Kaori Shirasaki/Relationships

Tomoichi Shirasaki
Tomoichi loves his daughter very much and treats her as the most important person in the world. Kaori loves her father very much as well but is antagonistic towards him at times due to his hostile attitude towards Hajime.

Kaoruko Shirasaki
Kaoruko loves Kaori very much and is more supportive of her relationship with Hajime than her husband.

Hajime Nagumo
Kaori had developed feelings for Hajime ever since middle school, but she only realized she had fallen in love after he fell into the abyss and became convinced that he had survived. After she reunited with Hajime when he rescued her and her fellow classmates from a Demon ambush, 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
A young dagon girl that Hajime rescued and later becomes his foster daughter. They are shown to have a good relationship but does not like it when she and Yue bicker around her.

Kouki Amanogawa
Kouki is one of Kaori's closest friends.

Suzu Taniguchi
Suzu is one of Kaori's associates.

Lundel S. B. Heiligh
Kaori was Lundel's first love. He unsuccessfully tries everything he can to keep Kaori out of the fighting and be by his side, but Kaori mistakes Lundel's as respect for one of the summoned heroes of Earth. Kaori confesses that he views Lundel as a younger brother much to his dismay.
