Hajime Nagumo
Kaori had developed feelings for Hajime ever since middle school and did everything she could to befriend Hajime in high school much to the latter's confusion, but Kaori only realized she had fallen in love with Hajime after he fell into the abyss. When Kaori reunited with Hajime when he came to rescued her and her fellow classmates from a Demon ambush, Kaori was immensely overjoyed but was completely shocked by Hajime's newfound ruthlessness when he coldly killed Cattelya, and how Hajime had truly abandoned most of his kindness and compassion which Kaori had admired Hajime for as when Kouki criticized Hajime for his actions, Hajime simply declared that showing unnecessary mercy to his enemies will only lead to his own death and if Kouki and her other classmates dares to go against him simply because they are against his way of doing things, he will massacred them all with absolutely no mercy even proving his point by holding Kouki at gun point and unleashed a full blast of Intmidation terrifying them out of their wits, making Kaori extremely confused by how much the man she had loved changed. After witnessing the last and only fragment of Hajime's lost kindness in protecting Yue, Shea and Tio, Kaori was determined to remain by his side no matter the cost she was determined to remain by his side no matter the cost. She along with Yue are the closest to Hajime due to madly falling in love with him since the beginning.

Yue
Kaori and Yue are normally seen arguing and fighting with each other over small things with most of their arguments revolving around Hajime or each of them trying to outdo the other. She's often told that they are really close to each other to the point of making Shea and Shizuku, their respective best friends feel envious toward their relationship. While she is usually shown to be antagonistic towards Yue, the two of them can work together effortlessly when the situation requires it and it does really seem like they respect and are friendly to each other.

Shea Haulia
Kaori is close to Shea as one of Hajime's companions and they love the same person though Kaori often feels jealous of her being the second person Hajime's accept as "Special" beside Yue. Despite her jealousy, Kaori rarely quarrels with her unlike Yue, they're always friendly with each other. Kaori considered Shea as a person that gives her hope by proving that Hajime's heart is capable to accept another girl's feelings.

Tio Klarus
One of Kaori's companions. She shares the same opinion with everyone with regards of Tio being a pervert. Though Kaori is shown to have some perverted qualities as well, she tries to hide behind Tio's antics in the hopes that it would overshadow hers. After Hajime accepts Shea as a lover, Kaori and Tio constantly support each other in order for him to accept them as well.

Shizuku Yaegashi
Shizuku is Kaori's most beloved best friend. She's really caring towards Kaori and often supporting and helping her to get along with Hajime. When Kaori is killed by Daisuke Hiyama during the invasion of the demon race, Shizuku is really devastated and almost breaks down if Hajime did not console her. After Kaori is revived, Shizuku is extremely happy and hugged her while crying loudly. Shizuku is very loyal to her as seen on her attitude that refused to accept that she loves Hajime because that would mean that she betrayed Kaori and will make her hate Shizuku. After Shizuku tells Kaori her feelings for Hajime, Kaori does not condemn her and instead asks her to rival against Yue and Shea along with her as comrades.

However, Shizuku becomes disturbed when Kaori starts displaying the qualities of a yandere and a stalker. She even feels bad for Hajime when Kaori starts making plans to get closer to him after she (Kaori) falls for him.

Myu

She was bothered by Daisuke's cruelty when he was bullying Hajime. She is unaware of Daisuke's betrayal until he murdered her to try make her as his undead slave until Hajime foiled it. After Hajime revived Kaori into a stronger body, Hajime revealed to Kaori of Daisuke's betrayal and had killed him.

Eri Nakamura
Eri was one of Kaori's closest friends in high school, whom Kaori affectionately refered as Eri-chan which the latter also seemingly reciporated by also addressing Kaori with the suffix chan and also offered any help and support she could give her after Hajime's supposed death, even strongly opposed to Suzu's suggestion to use necromancy to reanimate Hajime into Kaori's undead servant in case they had found his corpse out of consideration for Kaori. However, in reality Eri had never considered Kaori a friend, having been secretly and murderously jealous of her close friendship with Kouki, despite knowing Hiyama was the one behind the misfired fireball that led to Hajime's supposed death, Eri chose to kept it a secret from Kaori, even one sidedly offered to Hiyama to force Kaori into becoming his personal slave which Eri later proved by attempting to use Soul Bind on Kaori after she was killed by Hiyama for her to become his undead slave deprived of her own will. Despite so, Kaori held no grudge towards Eri for her involvement with her own death, even silently pleaded with Hajime to agree to Suzu's request to give Eri a chance for redemption.

Kouki Amanogawa

Suzu Taniguchi
