Character[]

The protagonist of this work. He was recognized as a descendant of the 2nd Emperor Schwarz, known as the God of War (Mars) in the other world, he is the 4th in line of succession to the Imperial Throne of the Great Empire of Grantzian, and his name was changed to Hiro Schwarz von Grantz upon his appointment as the 4th Prince. However, Hiro himself is the two great emperors of 1,000 years ago. One thousand years ago, he suppressed a civil war in the Empire of Grantzian and became a hero, returning to his original world. After returning to the original world, he goes about his daily life again with no memory, but one day he is transferred to another world again, but this time he returns to the Great Grants Empire where 1,000 years have passed since his transfer and meets the 8th in line of succession to the throne, 16th Princess Liz, who holds the Salt Emperor Sword, Levantine. While meeting her and traveling with her, he would awaken one of his abilities, Tenshoan (ウラノス). Thereafter, when the situation becomes unfavorable in the battle against the Duchy of Lichtein, Liz leaves Hiro with tears in her eyes. Later, Hiro becomes fully awakened while wandering around and remembering all his memories, and he saves Liz by killing 1,000 people of the Duchy of Richtine alone with the Heavenly Emperor. After that, he began to work as Liz' chief of staff. The independent forces led by Aura, the chief of staff of the 6th Imperial Army and the 3rd Imperial Army, were inferior to the Duchy of Richtine because they had fewer troops, but Hiro's military prowess and pointers led to the destruction of the Duchy of Richtine. He exerts his energy in a single battle with Reichl. Later, during a confrontation with Liz and the 1st Prince Chute Bell, Liz declares that Hiro is a descendant of the two great emperors, and two days later, he goes to the Great Institution to take a test.

The test was to wear the clothes Black Spring Princess, which only the 2 Great Emperors could wear, Black Spring Princess initially fell to the point of having put herself alone for a thousand years but was recognized as a descendant of the 2 Great Emperors by the Grand Empire of Grants while acknowledging the internal Hiro as his master again. Then, suddenly, a fourth prince, a being, appears and successfully handles the coming of a crowd of nobles in pursuit of Siri. Hiro then approaches Rosa Kelheit, widow and head of the Kelheit family, for connections and funds. Rosa Kelheit appeals to the point that she can gain the support of the Eastern nobles if she becomes lovers with him, giving Hiro a name that allows him to reject the mixed medicine that comes without boiling. Kelheit He says he wants a child to carry on the family crest. Hiro has nothing to do with holding hands, but when he says that the child is a specification, Rosa steps back and spends the night saying that she is satisfied with that. The next day, through a letter from the emperor, conveyed through Aura, he is ordered to invade the Duchy of Richtine, led by General Kilo of the 4th Imperial Army, and after promising Rosa his full support and asking for a favor, he joins the 4th Imperial Army. However, General Kilo of the 4th Imperial Army is not a great general, and after ordering Toris to find out the names of the captains of each unit cloth, five hundred, one hundred, and ten, and after ordering Liz to come forward to build trust from them, the 4th Imperial Army and prepare to have the command of the 4th Imperial Army transferred to Liz. He then takes away almost all of General Kilo's authority by thrusting out the imperial order that came down from the imperial court, and he prepares to fight the Duchy of Richtine through the military.

Then, after calling in General Kilo and the General Staff who would follow him, he would defeat and set up General Kilo and send him to the battlefield where he would be inevitably defeated. Then, after ordering the girder, a prisoner of the Emancipation Army, to defeat the general with the key during the battle under the condition that he see to the treatment of the Emancipation Army, he meets each of the four spies and gives the same information to three of them and money and other information to the remaining one, and then releases him. The Duchy of Richtine would fall into Hiro's trap and be defeated. The Duchy of Richtine then surrendered, handing over some territory and goods.

After this battle, he takes with him the resources of the mercenaries who had been in the army of emancipation, making Ghader his longevity, and forms his army of 3,000 allies, unified in black equipment, under Ghader's command. In the course of training, a bandit group composed of defeated mountain soldiers and deserters from the Duchy of Lichtein was formed, and the 4th Imperial Army went with a bandit group composed of 50 men, while Hiro went with a bandit group composed of 300 men. After conquering them without any damage by Hiro's strategy, they go up to the capital, Liz in the name of the emperor who asked them to participate if would cure their victory. During the parade, he realizes what a muddy girl, who does not even want to deal with commoners, is trying to tell him, and he stops the carriage to receive flowers for the girl and elicits a public cheer in the act of patting her head. Thereafter, after receiving a second-grade promotion in the first grade without a grade and receiving a fortune at the ceremony to meet the emperor, the hardliners and the prudent are divided when the emperor asks how the Grand Duchy of Doral will deal with the recent act of gathering troops on its borders, and Prince Stral, the first prince who was suspended at the same time as the largest speaker, Otoshi-sama, is the one who is the most humble of all. When he said that he would lead the 1st Prince's army to defend the border region of the Grand Duchy of Doral if he would be relieved, Hiro proposes to send some small troops to check Prince Stral and reinforce him a little, then send his army to the Felsen region to suppress the rebel army. The emperor adopted Hiro's middle and ordered Rees, who received the command of the 4th Imperial Army, to suppress the Pelzen area. Hiro was ordered to go to the coming-of-age ceremony envoy to be held in the allied kingdom of Levering and left for the Northern Territories with his men Gogin and Munin.

In the Northern Territories, Hiro meets the second prince of the sixth in line to the throne, Beerwolf shallum Selene von Grant, and senses that Selene is going to be a rather annoying person. Later, when he arrives in the southern part of the Kingdom of Levering, he is welcomed by Haniel Van Benchel, one of the Three Horsemen, who escorts him to the capital and meets the coming-of-age hero and princess Claudia. Since his meeting with Claudia, Haniel takes off to report that something has happened in his territory and arrives at the capital as she does. She begins to detect anger and hatred in the eyes of Prince Praus, who is next to the king when she meets him and gives instructions to her men, Munin, Hugin, and Dorix, in case of emergency. The next day, at the coming-of-age ceremony, a rebellion breaks out under the leadership of Praus, the king is murdered, and Baal and Galius, two members of the Wu Baba, join in and try to kill Claudia and Hiro. Hiro calculates the firing angle of the magic palace to lure Galius to a place of rest and succeeds in dropping him from a high place to buy time. He then manages to escape through the king's secret passageway, guided by Claudia. After a tangent where he decides to meet his men that way, he decides to move to the southern territories led by Haniel, and Hiro makes up his mind to prevent the Great Empire of Grants from trampling and devastating the country built by Rox the Furious, who fought alongside him friendly to the humans.

After seeing the scene where the rebels were badly slaughtered by the appearance of women and even Ai, he suppressed his anger and reached the main camp led by General Haniel, but Haniel had already been killed in battle due to Baal's schemes. Hiro decides to take on the nearly 40,000 rebels with General Haniel's remaining 5,000 men. Hiro, who had gained information about Baal by attacking the Spinal Corps alone, discusses with the military a scheme to raise the long-lived men's deception and succeeds in raising it after adopting all the proposals made by the long-lived men and saying that he would arrange it gently. Prince Serene, the second prince, brought a blank letter from the reaper asking if he should deploy a support force, but Hiro told the reaper that there was no need to send it since we had won the war. The Reaper is flustered by this, but Hiro explains that he does not have to come because the situation will be all over by the time he arrives, adding that he will send a detachment, and then he secretly entertains the Reaper and sends them on their way. He leads a hundred militia troops on a march to raise the soldiers' scam in a battle against the rebels. Lightly assessing the distance of the enemy's arrows, he stops them with appropriate instructions and succeeds in inflicting no damage, the con of his allies goes up, and when the enemy's con is a little shaken, Hiro provokes the enemy. He dares to snipe with his wall bow technique at the longevity of those who crossed over to provoke him. Later, in a confrontation with Galius, one of the trigeminal generals, he succeeds in taking out the Celestial Emperor and defeating Galius, and then he orders an assault on the enemy, who is completely shaken up, and rushes into battle. He then succeeds in having the rebel advance completely bitten back by allies coming in from both sides through Hiro's scheming. Thereafter, he succeeds in inducing Munin to deliberately spread false information and in luring the insurgents led by Baal toward Fort Schnee, and when Baal boasts that he has exhausted the contrast by his actions to reverse the false information, Hiro succeeds in treating Baal and suppressing the insurrection by implementing the measures originally taken by him. Afterward, the postwar process was handled by Claudia. He then peeks into Claudia's true nature while leaving the postwar process to Princess Claudia. Later, after telling Claudia, who readily admits, along with the story that Claudia had decorated the rebellion incident that took place under her starring, writing, and directing, Hiro recognizes that she and Sudan are too different, though she and he have the same goal, and says he will go his own way, Drix, Hugin, Munin and left for the Grand Duchy of Doral.

Once heard by the system, the emperor allows him to invade the Grand Duchy of Doral, and he leads 3,000 of his allies to the castle guarded by Captain Bakish von Haas, where he is heard and popularized and invades the Grand Duchy of Doral. Eventually, the Grand Duchy of Doral was in a situation where the northern part of the country was empty with the support of Felsen's remnant army in Palchen, and suddenly the Imperial invasion captured the nobles and soldiers of the Grand Duchy of Doral as prisoners. The nearby villagers are then evacuated elsewhere, and a fire is set near their town to create black smoke. The captured nobles are nobles who ultimately support his second son, Hunt Herben, who was in a power struggle with Palchen, so Hunt Herben sends his closest aide, Exe von Martina, to come and negotiate, and Hiro rejects the internal negotiation proposal on Hunt Herben's part and says that he will visit him and talk. Exe accepts the proposal. The next day, Hiro visited the enemy camp to meet with Hunt Haven by himself and was naturally subjected to an assassination attempt led by Hunt Haven's closest aide, Exe, but Kuroshunxi's power neutralized all of this and took control of Exe. Hiro then tells Hunthaven of their demands, but Exe says that he cannot believe the imperial troops who set the village on fire. Hiro responds by saying that the village will not burn and the villagers will be safe, finally, he offers Hunthaven the alluring words that he would like to win the power struggle, and Hunthaven eventually agrees to Hiro's threat and proposal.

Hearing that the Grand Duchy of Doral had been invaded by the imperial army, Farchen's army suddenly turned around and arrived at the castle where Huntthaven had been, as Hiro had planned, and answered with arrows to the words that they were reinforcements and would open the door, and opened the gates to engage him. The Bae Dong-dong-dong forces in the rear also cooperated to overrun Pakchen's army and succeeded in shooting Pakchen alive. Taking a knife to the back of the lively Pakchen's hand, he began interrogating him and said, “We treated him carefully, but he was not accustomed to life as a prisoner of war for an imperial princess who was bought in luxury. The sooner we go to rescue her, the better because she is overflowing with hatred toward us.” He expresses his affirmation in the words, but within a few minutes, after hearing the words he pulled out a knife took the back of his other hand, and gave it to the Pelsen remnants of the army to interrogate him again to see where he lied and the report that the Hanthaven army is coming again according to the promise, he sends Hunchen hanging on his beloved horse, Gale, to the castle that Bakish defends. Bakish defended the fortress.

He then forms a detachment and sets out toward Pelsen to save Liz, reaching Felsen through fast maneuvering and crushing the spreading positions of the Pelsen remnants of the army. He arrives to such a main advance, but he misheats when he sees Liz sleeping in the ice to the power of Geyborg, and while his spirit collapses for a while, he does not lose his life by preventing the attack of Skaaha, whose own subordinate post-Gin has struck Hiro's throat, but his Excalibur turns black in anger and shows a complete reversal of his appearance. However, Black Haruhi prevents a strong blow from Skaaha, and Hiro, who becomes a spirit again thanks to the blow, makes a deal for the seedlings, offering them to work as his water tribe if they wish to die at her word that she will incapacitate Skaaha and kill him. After the remnants are defiled and only Vese von Krone is called and lured into the room, Rahe, a member of the Pelzen remnants, who was in disguise as one of his men, stuns Vese, puts him in a horse sack, and then disappears to thank Hiro. Thereafter, he stops by what used to be the main camp of the Pelzen Remnants Army to meet Skaaha, who wants to fight under him, and places her under his command by signing a contract with her as a spirit.

After defeating Felsen, he returns to the system with Liz, Aura, and a hooded and disguised Skaaha, arrives at the home of the Rosa Kelheit family, the center of the eastern aristocracy, and reunites with Rosa. He then has his own man Ghader uses Munin's infiltration techniques to maneuver the Krone family to and from the fence of the mip-seeing family, and assigns Hugin to escort Rosa to and from the house. That evening, at the end of the meeting with Liz and Rosa, he adopts Liz inside, and when Liz leaves the room, he requests Rosa to support Liz in his claim to the throne and to work out an accusation against the Krone family, and they go to sleep together. The next morning, he begins to wake up to the sound of Skaaha and Liz' morning Dalian, agrees to Liz' words about going to Dalian with him, and at the moment he leaves the room to go down, he meets his subordinate Hugin. Hugin is quite turtled up to Rosa, but he reverts to his duty and enters the room, but is treated by Rosa as a doll to cuddle when he sleeps.

In a moment where preparations were being made to appeal for Liz's innocence after receiving a promotion and reward from the emperor during an audience, the emperor declared a six-month suspension for Liz and welcomed Zenpan. However, after that, Liz mentioned the tyranny of the Krohne family in Pelzen, and upon pursuit, the emperor agreed, punishing the Krohne family by confiscating their land and requiring them to cover all costs for the recovery of Pelzen. Hiro attempted to pursue the emperor, but at that moment, the first prince, Schutbel, declared that the annihilation of the Pelzen royal family was his sin and renounced his claim to the throne, missing the opportunity. Later, feeling Schutbel’s presence at a banquet, he chased after him, heard his heartfelt words, and parted ways. The next day, while trying to negotiate with the southern noble Musk family, leading his army alongside Liz, he heard the fact that the rebel forces of the Krohne family, under the command of former general Lowing, were marching under the pretext of condemning the emperor who had killed the head of the Krohne family. He combined his forces with the 3,000 troops left by Rosa of the army and confronted the 20,000-strong Krohne rebel army with 3,800 troops. Before engaging in battle with the rebels, he admired Lowing's command as he skillfully avoided the traps they had prepared, inflicting some damage, but considering the unexpectedly subtle extent of the damage, he raised the morale of the soldiers and charged. He succeeded in breaking through the center and striking Lowing, hoping to suppress the rebellion, but was surprised to find that Lowing was already in the process of becoming a mine, having decided to say goodbye to his family and clan for the sake of battle and to give up being human. Ultimately, he succeeded in eliminating Lowing. With Lowing's death, the rebel forces crumbled, and he informed Liz and Skaha of Schutbel's strategies he had learned from Lowing, sending them ahead to the imperial palace. After suppressing the rebellion, upon arriving at the imperial palace and seeing Liz and Skaha incapacitated by Schutbel and the dead emperor, they attacked Schutbel again in a reversed stance. They drove towards Schutbel right before killing him, but suddenly an anonymous secret booklet appeared, providing two pieces of useful and high-level information about Schutbel, disappearing while taking Schutbel with them, calling him the Black True King.

As soon as the rebel army was suppressed, a coalition army of 150,000 from six western countries attacked the west, as if they understood the internal situation of the empire. The western border fortress defended by Bakish von Haas of the Grantzian Empire's five great honors collapsed, and in the province of Perzen, 50,000 coalition troops attacked, leading to the third prince being isolated in a desperate situation. In response, Hiro decided that the third prince would gather air power and military strength in the province of Perzen, and when the time came, the third imperial army would join in to encircle and annihilate the Western coalition army. He would lead a currently operational force of 20,000 to carry out a delaying operation against the large Western army. After deterring the invasion from the Republic of Steisen that was peeking into the southern region with the fourth imperial army of Liz, he organized a plan to gather the Mujuk family's forces to support the capital. However, on the surface, Hiro had already completed negotiations with Rosa and Kaj Betulgar von Mujuk to prevent the invasion of the Republic of Steisen even before this operation was concluded, but they coordinated their words to protect Liz. He also had news of the third imperial army's defeat and the capture of the third prince. Although he could harm 150,000 with 20,000 at his discretion, doing so would turn him into a mere pawn to create a foundation for Liz to become emperor, and he would have to deal with the newly central noble, Orleans von Mark, all at once. To prevent the second prince, Bearwolf, from trying to protect only his spirit, he sent a secret letter to Queen Claudia of the Kingdom of Leveling in advance, agreeing to use ten capable assassins under his command in exchange for offering favorable conditions to the Kingdom of Leveling, along with receiving additional military support.

With Orleans von Mark as his adjutant, he advanced into the western territories with an army of 20,000 and collected information from refugees. As a result, he learned that most of the Western nobility had surrendered, and the son of Lord Kirshia, who was still holding out, was surrounded by the Second Conquest Army and was on the verge of falling. He wrote a strategy for the Second Conquest Army to annihilate them. During the battle, he used pre-positioned assassins to target and eliminate subordinates under Orleans, waiting for Orleans to take swift action. In the end, he sought out Orleans, who was reported dead but was alive and launched a surprise attack on the secret meeting of the nobles who had aligned with him, breaking their deception and extracting information from Orleans through brutal torture before executing him. Afterward, he faced an enemy main force of 180,000, but while organizing a separate unit to strike the enemy's main force, Kirshia betrayed him once again. To save himself, Kirshia informed Hiro of Orleans' betrayal, rationalizing that he would be forgiven because the residents of his territory were held hostage. However, Hiro could not contain his disgust at his shame and ultimately beheaded him. In the end, he fought against soldiers who did not betray him and the noble army that had betrayed him, but all the soldiers who threw themselves to allow his retreat died, and Hiro used all his abilities to deal with the betraying soldiers, biting a letter to his beloved dragon-man Shippū and sending it to Liz. After that, he fought alone against the Western-allied forces led by the main army, facing off against the siblings Lucca Almond Wulfes and Egel de Wulfes who were aiming for the ball. He defeated Egel Wulfes but was countered by Lucca, who was enraged by his brother Egel's death, and he blew Lucca away. Later, Lucia Revis de Angis recommended that Hiro join their side because of his connection to their ancestors, but Hiro rejected this and inflicted a fatal wound on Revis de Angis. Ultimately, due to the overwhelming number of fleeing soldiers, he was finally knocked down and fell.

≪Spoiler...≫

In fact, he is alive and becomes a warrior, acting as the Black True King (Surtr) and heading towards the small kingdom of Baum alongside his allies. His ultimate goal, while secretly working from behind, is to hinder the plans of the Five Great Kings and to combine the Five Spirit Swords to lift the curse of the first Emperor Altius's bloodline, thus freeing himself from the guilt of not being able to protect the Priestess Rei a thousand years ago.

The reason for writing the name Surt is that, a thousand years ago, Hiro, during his reckless battle against the Reckless King and in various places, began to seek a strong power to heal the deteriorating condition of the invited priestess, Rei. He wandered around and started visiting the Black True King. Despite repeatedly attempting to gain power through Danbi, he found himself lacking the strength to defeat the Black True King even with his demon form, and every time they interacted, the Black True King would ask Hiro if Danbi could even do something like that, leading to a friendly exchange between them. Later, when the Reckless King appeared with Hiro and the Black True King, it seemed that the Reckless King intended to turn Hiro into a demon and use him as a vessel for the Black True King, but instead, he came to visit directly.

Then, the Reckless King and the Black True King fought for three days and nights, and in a near-death state, the Black True King entrusted his core to Hiro, who absorbed it without losing the initiative to the Black True King, thereby becoming the current Black True King (Surtr). However, despite these efforts, the subordinates of the Reckless King attacked where Rei was recuperating, resulting in her death, which led to Hiro becoming corrupted and desperately longing for power. After capturing the remaining twelve of the Reckless King's subordinates, he committed heinous acts, such as gouging out their eyes to use them as his tools, while the Reckless King attempted to create a body for himself, either Altius or Hiro, but was ultimately noticed by Altius and returned to the present world.

However, when he was summoned again and the power of the Heavenly True Peace was released, all his memories returned, and he realized he was still not forgiven. He showed a distant, chicken-like demeanor as he calculated everything up to Volume 13. When Liz came to visit him again, he felt that the time had finally come to follow through. However, afterward, after being released by the Spirit King, he acted on his own accord, and when the Spirit King was absorbed by the Black Spring Princess, he charged at the Reckless King, seemingly losing control of his body, but actually succeeded in absorbing the Reckless King. He then appeared as an ally who had become a boss and ultimately engaged in a blood duel with Liz. Even the Heavenly Emperor Excalibur, who followed him as he wished, fell under Liz’s ownership, lifting her curse, and at the same time, he fulfilled her request to be killed.

However, through the choices presented by Altius in the afterlife, he chose to live life once more, activating the wine ceremony that Altius had planted in Levantine, and became an ordinary human. He later married Liz and had a daughter. However, upon realizing that she was the sister of Leon Kerlheit, the son of Rosa Kerlheit, he sometimes divided Rosa and Chun or even took on the role of father alongside Rosa.

Unexpectedly summoned to the world of Aletia from modern-day Japan, Hiro Oguro soon discovers this isn’t his first visit. As the legendary Hero King Mars, he once ruled battlefields, conquered nations, and founded the continent-spanning Grantzian Empire before giving up all memories of his hard-won glory to return home to his old life. Now he was summoned again, a thousand years after he left, and his legacy is in peril. In his journey, Hiro gained his memories from the past even his, and awakened his mystic eyes.

Among the five great protective swords of the world, this protective sword is passed down among humanity and is also known as the gift of the Spirit King (Regalo). It was refined by the first emperor, Altius, who received power from the Spirit King. His Swordsmanship can equal other superior swordsman and knights in the battle, because of this his instinct has been sharp.

"When Hiro was imprisoned in the prison during the story, he mentioned during a conversation with Scáthach:
"The Sword of Origin [Heavenly Emperor] is a vessel, the Sword of Steel [Nō-sei] imbues power, the Sword of Vitality [Kazamatsuri] amplifies strength, and the Sword of Sealing [Kōri-sai] seals the master."
"The Sword of End [Flame Creation] does not destroy everything."
"When all are gathered, the Spirit Sword Quintet demonstrates its true value."
The Spirit Sword Quintet can actually gather all under one owner to demonstrate its true value, and with that power, it can eliminate the Five Generations of Heavenly Kings.
However, due to Hiro himself (as the Heavenly Emperor chose Hiro), it did not happen, leading to the current situation.
There is also mention of the state, where the 23rd Emperor forced the Flame Emperor into submission, saving the chaotic Grand Empire while receiving the master, and the lineage continued down to the descendant Rees, which could lead to extinction if things continue as they are.
Therefore, it seems Hiro conceived a plan for Rees, who inherited the bloodline of Altius, to be recognized by the Spirit Sword Quintet and demonstrate its true value to simultaneously eliminate the Five Generations of Heavenly Kings (the core of the Five Generations of Heavenly Kings).
If the Five Generations of Heavenly Kings are eliminated, the issues related to the master would also be resolved, and even if he were to die, it appears he intended to rectify the current situation caused by himself.
(Of course, Altius, who foresaw Hiro doing this a thousand years ago, took measures to come back to life.)"

Among the five great protective swords "Dragon Emperor Sword Pentagram" of the world, this protective sword is passed down in the aquatic tribe, made from the harmful materials of the previous Black True King, the Black Dragon.

Since the invasion of the Principality of Lichtain, the army of Hiro's "Allies" has been formed mainly by slaves captured as prisoners and those who resource mercenaries. As it is a newly formed army, they unified under black equipment to intimidate the enemy. Currently, the army consists of 5,000 people, including reserve forces. During the era of the Two Great Emperors, their advance was so formidable that even the Demon King would flee, but when the Two Great Emperors disappeared and the Three Great Emperors ascended the throne, the emperor, fearing the power of the allies, lost his life and mobilized all imperial forces to kill them. During the time of the Fifth Emperor, once again, the name was removed, and since there were no descendants of the Second Emperor, no one referred to them as allies. However, Hiro, claiming to be a descendant of the Second Emperor, reestablished the allies.
