Biography
Daisuke was the leader of the pack of bullies that constantly harassed Hajime, even after crossing into another world, He only saw Hajime as incompetent. The harassment became worse after crossing worlds and discovering that he had better stats than Hajime, beating him during training and passing it off as him helping him train; since nobody else would.

During the classmates' exclusion into the Great Orcus Labyrinth, a giant glanz crystal was discovered on the 20th floor. Daisuke tried to take it in an attempt to impress Kaori, but it turned out to be a trap that transported everyone to the 65th floor. They soon found themselves on a stone bridge and was trapped between a behemoth and and army of traum soldiers. He launched a fireball spell at Hajime while everyone was bombarding the behemoth with magic and caused him to fall off the bridge into his apparent death. He had convinced himself that nobody had seen him shoot it towards Hajime; later blackmailed by a fellow classmate who had heard him confess to the attempted murder. This classmate understood the reasoning behind his heinous attack towards Hajime and manipulated him aid in their plans by promising to give Kaori to him as a reward.

After it was revealed that Hajime was still alive, Daisuke completely denied it until he saw Kaori cling to him. His desperation grew when Kaori decided to join Hajime's group and begged her not to leave, but was unable to convince her otherwise. This in return lead to him begging Hajime for forgiveness in hopes that he and his group would join his. Hajime denied his request by subtly dropping hints that he knew that Daisuke tried to kill him the day they got separated from his class. This left him in shock as Hajime and the others left. Daisuke has a complete breakdown that night over not only failing to kill Hajime but also losing Kaori, but was reassured by his blackmailer that it was not the end and that he could easily get her back.

Daisuke later took part in killing the kingdom's knights, including being involved in the death of Knight Commander Meld Loggins, during the war between the kingdom and the demon race. When the demons invaded the 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; this was in order to allow Eri to make her into a puppet for his lust towards her.

He was brutally beaten by Hajime, having almost all his bones broken, later being thrown to demonic beasts, where he died after he was half-eaten alive by the demon army's monsters.

Relationships

 * Hajime Nagumo - Daisuke hated the fact that Kaori was interested in Hajime than him so he decided to make Hajime's life as miserable as possible, alongside his three other friends. This would later escalate to physical violence after they were transferred to Tortus. 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. He begins to feel scared and intimidated that his plan will be exposed and witnessing Hajime's inhuman strength. When Kaori decided to travel with Hajime, He became desperate along with his gang pleaded Hajime to rejoin them while saying sorry for what they did in in the past but the in response Hajime give him hints that he knows what happened causing him to back off in order to stay alive. Later on, after he killed Kaori and Eri's attempted "Bind Soul" failed, because of Hajime's arrival, Daisuke becomes mad and starts badmouthing Hajime for his failure to make Kaori his, but it only enraged Hajime even more and beat him senseless and threw him into a group of demons where he was left to be eaten alive.
 * Kaori Shirasaki - Daisuke is shown to be deeply in love with Kaori to the point where he would follow the order of one of his classmates who was blackmailing him if it would get him closer to Kaori. He is even willing to accept an offer from the demon Cattleya if it meant that he and Kaori were the only ones to survive. In his insanity, he went as far as to kill Kaori himself so Eri could turn her into his undead puppet who would listen to his every command until he failed as Kaori revived by Hajime into a stronger body.
 * Reichi Kondou, Yoshiki Saitou & Shinji Nakano - his three former friends and partners in crime. Alongside them, he would bully Hajime as much as possible mostly because they liked Kaori as well. However, in truth, Hiyama doesn't care of his "friends" as they are nothing but merely tools in order to claim Kaori for himself. After his and Kondou's deaths by Hajime, Saitou and Shinji are too scared to cross him and decided to never bully him again.
 * Eri Nakamura - one of his fellow classmates and his fellow traitor. After she discovers that Hiyama was the one who discovered that he (almost) killed Hajime she uses this knowledge to blackmail him into working with her.
 * Other Classmates - most of the other classmates ignore Daisuke bullying Hajime. After Hajime's alleged death, they show their animosity towards him since it was his actions that transported them to the labyrinth floor where it took place. Though when Hiyama put up a false act of remorse in front of Kouki and Kaori, they readily forgived him due to Kouki's misguided justice and Kaori's immense kindness as well as their overwhelming popularity with their classmates with the exception of Shizuku who have some doubts about Hiyama's deception and manipulation though she chose to put aside it for the sake of looking out for her closest friends. Later, Hiyama assisted Eri in betraying his classmates by massacaring Meld and the other Heiligh Kingdom Knights to turn them into undead pawns for killing his classmates in a death trap even personally killed Kaori their beloved class idol to turn her into his personal undead sex slave. Hiyama's atrocities left an immense and permanent negative impact on all of his classmates particularly Kaori's closest friends, Shizuku, Suzu, Ryuutaro and most of all Kouki who had place misguided trust in Hiyama. When Kouki furiously accused and blamed Hajime for not warning them of Ehit's schemes earlier in the Orcus Dungeon that had allowed Eri and Hiyama to betrayed them, Hajime coldly stated it is their careless optimism and delusional idealism at fault that they had nearly died and reminded them it is precisely their ridiculously naive expectations that fellow classmates must always help and protect each other is what had allowed even an idiot like Hiyama to manipulate and backstabbed them without even realizing it, a fact that all of them could not deny. Having personally witnessed Hiyama's horrific fate of being brutalized by Hajime before being thrown to be eaten alive by monsters served as a strong warning of the terrifying extends of Hajime's savage brutality as they are terror stricken of being subjected to the same fate as Hiyama if they dared to cross Hajime, even Kouki despite his dedication to justice and digust of Hajime's cold and pragmatic disregard for morality did not have the courage to completely go against Hajime due to his immense power and ruthlessness.
