He was the leader of the gang who would often harass Hajime and the one responsible for his fall in Great Orcus Labyrinth.

Appearance
Daisuke is young man with with long brown hair, and has an arrogant expression on his face.

Personality
Daisuke often bully Hajime because of his jealousy to the attention that Kaori was giving towards him. After being teleported to Tortus, his bullying towards Hajime rises to a great extent by using violence and disguising it as a part of training. It also comes to the point of him attacking Hajime on the bridge causing him to fall which resulted of him to become paranoid and tries to justify his actions.

He was also shown to be a disloyal man who only cares for himself and would be willing to abandon others when things get dangerous as he was willing to accept Cattleya's offer to join the demons side if meant for his survival.

After learning of Hajime's survival, he became scared and desperate in having Hajime forgive him. He also became afraid and enraged of the fact that the once weak Hajime gained strength stronger than himself but also lost Kaori in the process. This caused him to fall into insanity, 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.

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. His desperation grew when Kaori decided to follow Hajime and begged her to stay, but was unable to convince her otherwise. This resulted in him begging Hajime instead and asked him for forgiveness to comeback. However, Hajime denied his request 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.

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.

He was later beaten by Hajime and throw to a group of demonic beasts, where he died after he was half-eaten alive by the demon army's monsters.

Enemies

 * Hajime Nagumo - Daisuke hated the fact that Kaori was interested in Hajime 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. 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 demonic strength. When Kaori chose to travel with Hajime, He became desperate along with his gang pleaded Hajime of joining his party (just so he would be closer to Kaori) 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 stay out of his way if he wish 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 and Hajime watch pitilessly.
 * Kaori Shirasaki - Daisuke was shown to be deeply in love with Kaori to the point where he would do anything jut to obtain her. He was even willing kill her so that Eri could turn her body into an undead puppet who would listen to his every command.
 * 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. Daisuke didn't hesitate of letting Eri killed Kondou.
 * 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 forgave 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 had 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. After his betrayal was revealed, as well his desire to turn Kaori their beloved class idol into his undead slave, it 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 disgust 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.
