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. In the harsh journey, Hajime offered her to return back to the kingdom but Kaori refused and still remain in his side no matter how harsh the journey would be. After Daisuke murdered Kaori, Hajime used Spirit magic to revive Kaori by transferring her soul into Noint's body as a vessel, as Kaori wanted to become stronger so she could stay by his side. After Haltina Labyrinth, due to realizing how much his comrades (the harem) meant to him after his feelings about them were magically reversed due to magic, Hajime was forced to publicly admit that even Kaori had a chance to make him fall for her. She eventually success and became one of his wives.

Yue
Kaori meets Yue during the ambush of the Hero party. While curious about her at first, Kaori becomes enraged when Yue implied that she is unworthy of Hajime due to being shaken by his transformation and unsuited to becoming her rival in love. She decided to prove Yue wrong and steal the position of Hajime's precious person from her. 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.

Kaori is the only person who can understand Yue's incomprehensible explanations about magic as was shown when Yue taught Kaori how to use metamorphosis magic.

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. After Hajime fell into the abyss and Kaori wanted to see his fate with her own eyes, Shizuku promised to help her despite not believing that Hajime survived. During the ambush of the Hero party by Cattleya when it appeared that Shizuku would be killed, Kaori rushed to her side, stating that if she is to die then she would die by Shizuku's side. After Kaori made the decision to travel with Hajime, Shizuku was the main person to support her, even making Hajime promise to treat Kaori nicely by threatening to embarrass him by making up chuuni nicknames for him. 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. When Shizuku starts travelling with Kaori, she notices Shizuku's growing feeling for Hajime and subtly encourages her by telling Shizuku to be more honest with her self and that she needs to consider her own desires. 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 team up 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.

Daisuke Hiyama
Daisuke was deeply in love with Kaori. However, Kaori herself, doesn't hold the same feelings for him as she is already fallen in love with Hajime Nagumo. 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.

Ehit
Kaori once respected the supposedly benevolent god, Ehit while under the Hero party. However, when she learned from Hajime of Ehit's true nature as an evil god after being used as a pawn like the rest of her classmates, Kaori lost all of her respects for the god and remained in Hajime's side of his journey to opposed the god's intention for them to be his pawns in order to return back to Japan. Kaori's digust of Ehit has increased after personally witnessing visions of his past atrocities of instigating his worshippers to fight brutal religious wars and sacrificing innocent people for his twisted entertainment in the Sunken Ruins of Melusine as well as learning from Liliana how Ehit sent Noint to abduct her teacher Aiko and brainwashing her father King Eliheid and his ministers.

Kouki Amanogawa
Kouki is one of Kaori's closest friends. Kaori has known him since elementary school along with Shizuku as the three of them were always together all of the time. It is due to Kouki's presence that most boys that harbored crushes on Kaori didn't confess to her as they thought that they couldn't match up to Kouki. Unlike most other girls, Kaori is immune to Kouki's handsome looks and his charming personality as she knew how dense he was as well as his habit of interpreting things to his liking which prevented her from seeing him in a romantic light. It is due to his denseness and habit of interpreting things to suit his worldview that he was incapable of noticing Kaori's romantic feelings towards Hajime. Kouki treasures her and believes that they will always be together which is why he could not accept the fact that she wanted to join Hajime even going as far as to try to force her to stay with him by disparaging Hajime. During the trial in the Frost Cravens of Schnee, Kaori noticed and started worrying about Kouki's growing hostility to Hajime, as Kouki was proclaiming his desire to save Tortus from Ehit in a spiteful tone to Hajime. When Kaori arrived to Hajime and Kouki's deathmatch, she was shocked by Kouki's frenzied state as he attempted to kill Hajime while proclaiming his desire to reclaim Kaori and Shizuku for himself. Kaori, along with Shizuku, managed to convince Hajime to spare Kouki's life, despite Hajime's desire to kill him to avoid that kind of situation again. When Kouki wondered if it would have been better if he feel into the abyss instead of Hajime, Kaori slapped him as she became angry and sad due to him disregarding how much that event cause her pain. She begged him to not say such hurtful things as he was one of her precious friends.

Ryutarou Sakagami
Ryutarou is one of Kaori's closest friends in high school. She is close to him and cares for him but is sometimes exasperated with his behavior. Due to being the party healer, she becomes irritated when Ryutarou foolishly charges ahead without planning or considering his actions, which results in him getting injured. During the trial in the Frost Cravens of Schnee, Kaori became particularly irritated with him due to him being reckless in his fight with the Frost Golem, so much so that she asked if there exist a healing magic that leaves pain in it's targets. Kaori also dislikes being accused of being as reckless as him.

Suzu Taniguchi
Suzu is one of Kaori's closest friends in high school, whom Kaori affectionately refered as Suzu-chan. Suzu did her best to support Kaori by cheering her up when she was traumatized by Hajime's supposed death. After Eri's betrayal, Kaori attempted to help Suzu in reaching Eri by convincing Hajime to allow Suzu and the rest of the Hero party to travel with them. Kaori feels guilty whenever she accidentally causes Suzu to get depressed by mentioning Eri. After clearing the Frost Caverns of Schnee, Kaori promised to accompany Suzu to confront Eri and protect her if Eri attempts to harm her.

Lundel S. B. Heiligh
Kaori was Lundel's first love but broke up when she chose to leave him to join the Hero party. 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.
