- Daisuke to Hajime

Due to the attention that Kaori was giving Hajime, Daisuke tended to bully Hajime. After being transported to Tortus, his bullying rose to a greater extent where he started using violence and justify it as sort of their training.

Daisuke was shown to be a disloyal individual as was willing to abandon others if necessary, he was even willing join the enemies' side if its to guarantee his safety. He was also shown to be obsessed with Kaori and tried to apologize to Hajime after Kaori's declaration of joining Hajime's group just to let Koari stay with them. He was even willing do everything just to make her his and collaborated with Eri just to obtain Kaori even if it meant on killing her.

Daisuke can also be easily manipulated by those when Eri blackmailed him to part of her schemes.

After learning of Hajime's survival and seeing his new found strength, he cower and became terrified of him. However, he was left terrified even more when Hajime not only refused to forgive him, but revealed he didn't even care about his previous mistreatment which no longer meant anything to him anymore as he could see the madness and lack of sincerity in Hiyama's eyes by calling him and his gang worthless and weak. When Hajime revealed he was already aware of his actions and exposed Hiyama as the one responsible for his fall, Hiyama had a complete mental breakdown and became a deranged lunatic. Unlike his former gang who easily give up their pursuit on Hajime and their chance for Kaori's attractions, Hiyama was the only one who is very persistent for refusing to give up on Kaori's attraction due to his hatred towards Hajime having gotten even worse than usual. Despite it, Hiyama doesn't have the courage or strength to against Hajime when it's already too late to kill him this time as he had became more powerful even more than Kouki.

Like both Kouki and Ryutarou, Hiyama is an extremely reckless and ignorant dimwit when he foolishly attempt to kill his enemies without even thinking only to result of his ease defeat by his enemies as it demonstrate when he foolishly attacked Hajime only to be easily defeated and later killed by Nagumo.

Much like Kouki, Hiyama is also delusional when he believed Kaori is his which is only an empty fantasy from his head. Even when he was defeated by Hajime so easily, he is even more deluded to think he swore revenge on Hajime for ruining his last chance of taking Kaori for himself as well foolishly declare he will kill Nagumo no matter what it takes which is still an empty threat when Hajime killed him by feeding him to the monsters.

He also became afraid and enraged at the fact that not only the once weak Hajime gained strength that holds far more superiority than his own, but he will never get Kaori to be his girlfriend for the rest of his life. This caused him to fall into insanity to become a crazed lunatic, as he was willing to take part in Eri's plan if it meant he could have Kaori, even going as far as to kill her himself so Eri could turn Kaori into his undead slave. When Hajime ruined Hiyama's only chance to make Kaori his girlfriend and being betrayed by Eri, Hiyama badmouthed Hajime for ruining his chances even when he was severely injured, Hiyama has proved to be a more dimwitted and persistently sore loser when he attacked Hajime with a fireball before he could kill Eri despite her betrayal towards Hiyama and continually blamed Hajime for always getting Kaori's attractions and bragged his last words that he would will kill him no matter what it takes only for Hajime to tell Hiyama that his claims will be impossible for him as well Hajime telling Hiyama that he will not expect the latter to survive when Hajime kicked Hiyama to the courtyard as the monsters are approaching as Hajime expected. While severely injured and unable to move or fighting back, Hiyama is also terrified of the monsters as they are shown up to eat him alive as he screamed in agony and terror when they are continually devouring him as well tearing him apart after Hajime walked away and abandoned Hiyama to his miserable death.

Ironically, it was Hiyama's own arrogance and delusional fantasies of Kaori has lead himself to his own failures as well as his downfall due to his lacks of responsibilities and repentances. His own insolence has also lead himself to his demises when he was devoured to death by the monsters after Hajime easily defeated him.

Biography
Daisuke was the leader of the gang that constantly harass Hajime. Even after the summoning and the fact that he had superior stats than Hajime, the harassment became worse as he begun using violence during training sessions by disguising it as a part of their training.

During the their exploration into the Great Orcus Labyrinth, Daisuke tried to take a giant Glanz Crystal in an attempt to impress Kaori, but it turned out to be a trap and transported everyone to the 65th floor. They soon found themselves at a stone bridge and was trapped between a behemoth and and army of traum soldiers. At the end of the battle, he attacked Hajime while everyone was busy bombarding the behemoth and caused him to fall off the bridge. He later convinced himself that nobody was aware of his actions but eventually he was blackmailed by a fellow classmate and manipulated him by promising to give him Kaori as a reward if he help her with her plans.

Upon learning of Hajime's survival, Daisuke completely denied it until he saw Kaori cling to him. When Hajime killed Cattleya, Hiyama shown in fear and terrified of Hajime. His desperation grew when Kaori decided to join Hajime to stay by his side, but was unable to convince her otherwise. This resulted in him begging Hajime instead and asked him for forgiveness to comeback. However, Hajime refused his offer by subtly dropping hints that he knew who was the culprit behind his fall which left him in shock as Hajime and the others leave. Daisuke completely broke down afterwards but was reassured by Eri that he could easily get her back.

Betrayal and Death
Daisuke participated on killing the kingdom's knights and was involved on killing the Knight Commander Meld Loggins. When the demons invaded the Heiligh Kingdom, all of the students discovered that Daisuke and Eri were traitors when Eri commanded her army of undead knights to subdue her classmates. Unfortunately, Daisuke's betrayal was not discovered until he murdered Kaori by stabbing her heart.

When Eri attempting to used her "Blind Soul" on Kaori's body, Hajime arrived and disabled her spell caused Hiyama to be angry. When began to fight, Hajime kicked Hiyama straight to the wall damaging his internal organs and breaking his bones.

When Hajime about is about to kill Eri, Hiyama foolishly attacked Hajime with a fireball (but has no effect on him at all) and was later beaten by Nagumo and kicked Hiyama out of the courtyard with a group of demonic beasts, where he died and abandoned by Hajime and the others to his miserable death after he was half-eaten alive by the demon army's monsters.

Legacy
Later, after the war in Heiligh Kingdom, what was left of Hiyama's dissected corpse was discovered and later buried near an unmarked grave. Hajime enlightened his old classmates that Hiyama was the one who caused him to fall intentionally, not accidentally which caused the "Hero Party" to retain their bitter memories of their hatred toward Hiyama back at school and the traitor he became and not sympathize. Hiyama's former falsely friends, Yoshiki and Shinji, apologized to Hajime and swore to never cross him or his comrades allowing Hajime to keep Kaori for himself. Even after returning to Japan, his classmates have not forgetten Hiyama's betrayal and never respected him since.

After the remaining students returned to Earth, Hiyama's family learned of Hiyama's death through Hajime and Aiko and attempted to get revenge on Hajime for killing him, but suffered a complete breakdown by mysterious means from Hajime in retaliation for their efforts.

Relationships

 * Hajime Nagumo - Daisuke's former bully victim from the past, but now his direct murderer. Daisuke hated the fact that Kaori was interested in Hajime and not him so he decided to make Hajime's life as miserable as possible. This would later escalate to physical violence after they were transferred to Tortus and Daisuke obtained a strong combat job compared to Hajime's non-combat job. It would escalate to attempted murder after he saw Kaori coming out of Hajime's room one night. Later, after finding out Hajime had survived the fall into the abyss, he begins to feel scared and intimidated that his plan will be exposed and witnessing Hajime's monstrous strength. After Hajime murdered Cattleya, Hiyama is terrified of Hajime of his demonic powers and ruthlessness. When witnessing Hajime tell Kouki of he will kill him even if they were classmates, Hiyama shown in greater fears. When Kaori declared she is leaving with Hajime, Hiyama's fears has became even worse when witnessed Hajime easily defeated Kouki in an unarmed duel of Kouki's failed attempt to take Hajime's party (harem). When Hajime and his party prepare to leave for their journey while Kaori joining them, he became desperate along with his gang pleaded Hajime to join the Hero party (just so he would be closer to Kaori) while feigning an apology for the treatment they gave him in the past but in response Hajime has told Hiyama that he doesn't care for his early mistreated anymore and gave him some hints that he knows what happened by calling Hiyama and his gang to be worthless and weak, subtly warning Daisuke to stay out of his way if Daisuke wished to stay alive caused Hiyama to fall into insanity and not only Hajime has obtained strength far superior than him, but lost his chance getting Kaori to become his girlfriend. Even in his insanity, he feared if he harmed Hajime's harem (including Kaori), he will be killed by Hajime in cold blood. Later on, after he killed Kaori and Eri's attempted "Bind Soul" failed, because of Hajime's arrival, the wounded Daisuke becomes mad and attacks Hajime with a fireball (but has no effect on him) while badmouthing Hajime for Daisuke's own failure to make Kaori his girlfriend, but that only enraged Hajime even more as he brutally thrashed Daisuke as he breaks almost all of Hiyama's bones and damaged his internal organs. While Hajime gripped the severely wounded Hiyama at his neck, Hiyama blamed Hajime for gotten Kaori's attractions but Hajime responded as he told Hiyama to stop blaming others when they gotten affections from beautiful girls even if they're idols. Hajime has sadistically tormented Hiyama as the latter considered his level to be a stoop while back at school and on Tortus due to his lack of responsibilities and always sits around insulting people as Hajime called him a weak, selfish and pathetic bully which is the main reason Kaori will never fall in love with Hiyama and will never become his girlfriend for the rest of his worthless life as Hiyama brought nothing but his failures and his own downfall. When Hajime was willing to offer him to repent his actions and realize his wrongdoings in order to spare him, the dimwitted Daisuke was persistently bragged his final words that he will kill Hajime and make Kaori his girlfriend one day which is only an empty threat. With these insolence, Hajime had quite enough of Hiyama's persistently and delusional beliefs as he put out of Hiyama's misery, making his death more painful and despair after kicked him out of the courtyard into a group of Freid Bagwa's monsters where he was left to be eaten alive and Hajime watch pitilessly as Daisuke was screaming in terror and agony but he then walked away and abandoned Hiyama to his death to confront Eri of her betrayals after Hajime got revenge of Daisuke for not only what he did to both Nagumo and Kaori, but also the innocent people that he had murdered for Eri's evil schemes. Hajime then ruined Hiyama's already tarnished reputation when he enlightened his classmates the truth of his "fall" incident including the part there was never an accident causing the so-called "heroes" to lose the slightest sympathy they originally had for Hiyama and completely wrote Daisuke Hiyama as a self-deluded traitor.

He was even willing kill her so that Eri could turn her body into an undead puppet who would listen to his every command but failed due to Hajime's arrival. Hajime killed Hiyama not only to avenge Kaori, but also the innocent people that he has murdered. After Daisuke's death and Kaori's revival, Hajime revealed to her of Daisuke's betrayal and he killed him for his stubbornly betrayal.


 * Eri Nakamura - One of his fellow classmates and his fellow traitor. After she discovers that Hiyama was the one who discovered that he failed to kill Hajime which turn him into a monster as she uses this knowledge to blackmail him into working with her but failed due to Hajime's interference.

While Eri witness of her pawn of being so weak against Hajime, Eri has turned her back on Hiyama and betrayed him when trying to convince Hajime to make Kaori as his slave.
