Allies

 * 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 from the past. But now they are terrified of Hajime after he murdered Cattleya not only his monstrous strength and ruthless but lost Kaori in process due to her love for Hajime alone. However, in truth, Hiyama doesn't care of his "friends" as they are nothing but merely tools in order to claim Kaori for himself and betrayed them when he let Eri killed Kondou. After Hajime killed both Kondou and Daisuke, two of Daisuke's so-called "friends" Nakano and Saitou were terrified to cross Hajime and not wanted to met the same fate as Daisuke when they apologized to Hajime and will never get in his way or harming his comrades (harem) including Kaori.
 * 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 which turn him into a monster as she uses this knowledge to blackmail him into working with her.
 * Ehit: Though not meet face to face, Ehit is amused of Daisuke. Daisuke works for the god along with Eri to kill all of his classmates and reanimated them as their undead slaves.

Enemies

 * 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 chose to travel with Hajime, 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 in the past but in response Hajime gave him some hints that he knows what happened, subtly warning Daisuke to stay out of his way if Daisuke wished 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 attacks Hajime with a fireball (but has no effect on him) while badmouthing Hajime for Daisuke's own failure to make Kaori his, but that only enraged Hajime even more as he brutally thrashed Daisuke breaking almost all of his bones and damaged his internal organs. When Daisuke was bragging how he will kill Hajime and make Kaori his one day, Hajime put out of Daisuke's misery after threw him into a group of demons where he was left to be eaten alive and Hajime watch pitilessly and Daisuke was screaming as Hajime got revenge of Daisuke for killing Kaori but not caused Hajime fell to the bottom abyss.
 * Kaori Shirasaki - Daisuke was shown to be deeply in love with Kaori to the point where he would do anything jut to obtain her but failed due to not only Hajime's survival, but his monstrous strength as well. 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 to only avenge Kaori. After Daisuke's death and Kaori's revival, Hajime revealed to her of Daisuke's betrayal and had killed him.
 * Other Classmates - most of the other classmates ignore Daisuke bullying Hajime. But in truth, Everyone hates him and his gang deeply for their selfishness lust for Kaori and bully many people including Hajime. After Hajime's alleged death, they show their more 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 or harming his comrades (harem) including Kaori, 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. After they were given by Hajime's warning, they still held bitter memories of how they hated Daisuke for what he have done while back in school and Tortus.
