Heisuke Okami/Relationships

Akari Okami
Heisuke has a rather complicated relationship with his mother. The two love each other very much, and Akari has claimed that she does her best for him despite everything (she had him at the age of 16, so she never completed high school), it is often Heisuke who ends up being the responsible one in the family. This is due to Akari having a track record of being attracted to mean looking men, who are often strange or even dangerous. These men have then abused or used either her, Heisuke or the both of them in one way or another. Because of this it can be said, that she and her bad decisions are the core reason for most of Heisuke's troubles- yet despite this, Heisuke does not blame her, and is seen taking care of her when needed, proving how dear his mother is to him.

Unnamed Father
Heisuke did not have much of a relationship with his father, however, he is noted to look like him by one of Akari's exes. This is later on somewhat contradicted by Jiro, who theorises that the reason for why Heisuke and Yuu look alike is because they both look like Akari. It can then be assumed that Heisuke bears a striking resemblence to both of his parents.

According to Heisuke, Akari's attraction to mean looking men can be tied to the way his father looked.

Unnamed Grandmother
Heisuke was noted to be very close with his grandmother, and had promised her that he would graduate high school.

Yui Sendo
Heisuke and Yui are ex step siblings from one of Akari's previous marriages to Yui's father. Despite no longer being official family, Heisuke and Yui still considered each other family (though Yui denied this when questioned about it by Kota). Their personalities resemble each other very much, though out of the two, Yui is more proud and reserved, making her somewhat more hard to approach by nature (Heisuke was this way mostly because of the way he looked). Heisuke has spent most of his high school years not associating with her due to him being a delinquent and not wanting to harm Yui's reputation any further.

The two are very protective of one another, as seen by the multiple sacrifices Heisuke makes for Yui throughout the series, but also when Yui acts hostile toward Kako, who, despite having rejected Heisuke, was still on friendly terms with him, which to Yui came off as her leading him on to hurt him.

According to Heisuke, his mother and Harada ended up adopting Yui into the family, and she now spends a great deal of time with them.

Yuu
Yuu is Heisuke's half brother, and he is introduced while being babysat by Heisuke. According to Jiro, the two look alike.

Hajime Harada
Harada became Heisuke's step father, when he and Akari got married. Together they had Yuu, Heisuke's half brother.

Heisuke did not seem too thrilled about Akari and Harada's relationship at the start. Whether or not his opinion of this ever changed is unknown, but at least he and Harada seem get along fine.

Kako Motoya
Heisuke and Kako's relationship did not start out all rainbows and sunshine. After accidentally hitting her on the head, Heisuke was left feeling guilty, but found himself unable to apologize to her, for Kako was severely afraid of him. It took a little bit of trickery on Heisuke's part to get Kako to talk to him, leading to her noticing that Heisuke might be a good person after all, and forgiving him. Kako then proceeded to include Heisuke in her friend group, allowing him and Jiro to become best friends in the process. At some point, Heisuke ended up falling in love with Kako, but he later came to find that Kako was already in a relationship with another person. It helped him to get in terms with this when he found out that at least Kako's boyfriend (who, from the image of him that he had seen, seemed like another delinquent) was actually a rather smart, good person. It then came as a shock to him, that this boyfriend was Kota, the person he had sworn to hate.

When Heisuke believed that he was never going to see Kako again, he ended up confessing his feelings for her. It was then Kako's turn to fool Heisuke into talking to her one more time with his tricks, and Heisuke once more confessed to her, making her cry. Having come properly clean about his feelings, the two continued being friends, though Heisuke swore that he would steal Kako away from Kota. He never did this, however, as he respected Kako's feelings too much to even attempt pursuing her romantically. Instead, he eneded up supporting Kako and Kota's relationship when they were going through a rough time.

Heisuke loves Kako very much, and has not dated anyone since Kako got married. This is mostly because he felt like he did not have time for dating, and because he did not want to have to explain things about his past to a potential girlfriend.

Throughout the series, Heisuke is shown to be very protective of Kako. He has been shown (misguidedly) protecting her from Kota on multiple occasions, as well as protecting her from his old delinquent friends and the two's classmates. He often stands up for her, and is eager to help her in any way he can. Similarly, Kako will also take every opportunity to protect or help Heisuke, even going as far as protecting Yui, despite not having a good relationship with her, just because she wanted to help Heisuke and those he holds dear.

Jiro Nagakura
Heisuke's initial reaction of Jiro was very much the same as everyone else's; he thought the boy to be incredibly stupid. However, with time the two grew so close, they consider each other best friends. Not much of their budding friendship is shown in the series, however, it is mentioned that Heisuke often gets dragged into helping Jiro with his studies or hanging out at his place.

Heisuke mentions that it is Jiro's influence on him that has enabled him to cry more easily. He and Jiro are shown helping each other often, and it seems like they consider each other's sisters as shared (meaning that Heisuke sees Ichika as a sister and Jiro sees Yui as a sister). Kako also notes that Jiro has probably been Heisuke and Yui's only supporter up until she and Mikado found out about Yui's situation.

Mikado Yaguchi
Heisuke and Mikado are close friends, however, out of the group, these two are shown interacting the least. That being said, because Heisuke is not as protective of Mikado as he is of Kako, he ends up sharing more about his life to her than to Kako (though he seems reluctant to do so).

Kota Sagano
Heisuke and Kota's relationship starts out cold, to the point that Heisuke felt a deep resentment toward him, and Kota only saw Heisuke as a no-good brat. Because of their negative views on one another, the two often ended up in situations, where they tried to protect Kako from each other, thinking that she should not associate with the other. Their shared overprotectiveness of her ultimately led to a small fight, when Heisuke found out that Kota was dating her, and immediately assumed the worst about the relationship. It was then Kota was forced to reveal that he and Kako are in fact married, which further shocked Heisuke.

After this, the two slowly start developing a closer relationship, as Heisuke and Kota become something akin to frienemies- they are rivals in love, however, Kota also saved Heisuke from Akari's abusive ex, and often helps him in different ways, such as giving him advice, involving himself with Yui's case and even helping Heisuke pass his police academy exams and interview. Heisuke sees Kota as a rolemodel, and so, it is also Heisuke who is able to help Kota at the end of the series, when Kota starts losing his grip on life.

Ichika Nagakura
Ichika, Jiro's little sister, has a crush on Heisuke. He, on the other hand, cannot see her as anything other than another little sister, and is thus very clear in his approach to not lead her on. This does not affect her feelings, however, as seen in Case. 62, where Ichika, now a high schooler, is still very much infatuated with Heisuke.

Heisuke is shown to be very attentive and good at taking care of kids, which is where Ichika's feelings for him stem from- he ended up helping her get back to Jiro during the Oto High School cultural festival. After this, Ichika is always excited to see Heisuke, and even makes him valentine's day chocolates.

Just like Yui, Ichika knows of Heisuke's feelings for Kako and thinks that she is leading him on in order to hurt him and his feelings.

Ryu Katsunaga
Ryu thinks of Heisuke as Kota's protégé, and likes to tease him about it, almost to the point of being relentless. It can be assumed that Heisuke respects Ryu, as he was one of the main players in saving Yui from her father.

Kaoru Sagano
Heisuke and Kaoru are shown interacting only once, and at that point, Kaoru begs him and Kako to help Kota get out of his mental slump. Heisuke proceeds to do as she asks, and is very respectful toward her.
