Aniplex Kiznaiver cover

Katsuhira Agata (阿形 勝平 Agata Katsuhira), whom Chidori Takashiro refers to with the nickname "Kacchon", is the main protagonist of the series.

He resembles the sin of Sloth. In modern Japan, his sin is "Gudon" (The Imbecile) meaning Idiocy. His identification number that appears when the Kiznaivers experience pain is D-1.

Appearance Edit

Katsuhira is a teenage boy with silver eyes and white/brown hair.

PersonalityEdit

Katsuhira was initially rather indifferent in all situations, whether he feels pain or joy. He was shown to be emotionless and is also shown to be oblivious to the feelings of other people, despite wanting to build bonds. Due to his lack of interest in himself and others around him, he had trouble forming connections, with the exception of Chidori.

However, it seems like his lack of interest started in grade school, as Chidori's love confession stated that she wished he would go back to his fun and caring self.

Katsuhira, despite having little emotion, does care for those around him, even to the point where he is willing to risk his own safety for the other Kiznaivers, including jumping off a bridge early in the series to prevent Tenga from doing the same thing. His mood barely fluctuates, and he pays little attention to other people. He is constantly bullied, but doesn't feel the pain.

In episode 10, Katsuhira is shown to be a shy yet energetic boy before the first Kizuna experiment. In that same episode, it is also revealed that once he was permanently connected to Sonozaki, most of his pain and emotions went to her, thus leaving his personality diluted, and his attitude towards others indifferent.

However, throughout the series, he gradually returns back to the same kind, thoughtful and sociable boy he was back then. He is also very forgiving, as seen when he holds no grudges towards others despite what they put him through, especially Sonozaki and Tenga as well as his bullies. This new personality was retained in the anime's sequel, "Pop'n Music 19 TUNE STREET: The Kiznaiver Arc".

AbilitiesEdit

While technically a disability, Katsuhira does not feel pain. This means when the other Kiznaivers are affected by someone else's or their own pain, Katsuhira is not inhibited at all. Despite this, he still bleeds and takes damage when his own body is injured. It is later shown that most of his pains goes to Sonozaki due to their permanent Kizna bond, but when he feels emotional pain, it hurts him as said in the show multiple times.

Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more rare conditions in which a person cannot feel (and has never felt) physical pain.

RelationshipsEdit

Noriko SonozakiEdit

Though Katsuhira claimed that he did not know Sonozaki, the two of them were experimented on as children, though he does not remember this. In the beginning, Katsuhira's heart starts to race when Sonozaki gets really close to him. She takes note of this and asks him why, and he responds that he has never been that close to a person unless they were beating him up. Rather than calling her Sonozaki like the rest of the Kiznaivers, he calls her Nori-chan, causing Chidori to get jealous at first. He is also the first to ask for her contact information and invited her to the summer training camp in episode 5. In episode 6, Katsuhira finds Sonozaki and expresses his disappointment towards her, which is the most candid thing he has ever said to anyone. As well as him being extremely truthful towards her, it seems as if he thinks very highly of her, which is why he was disappointed with her actions. It seems that she is the key for remembering his past.

In episode 8, the Kiznaivers had another mission/experiment about love. A chart is drawn with all the love interests and it is said by Noriko that Katsuhira's love interest is her. Noriko leaves the lab to see if she can draw out Katsuhira's romantic feelings. As he has flashbacks about his childhood and Noriko, he runs outside just when Chidori was about to confess to him. He saves Noriko from a falling statue and sees that Noriko herself is the girl who he had constant flashbacks about. At this point, Noriko says that he exists inside her because she wants to find herself (because she isn't capable of feeling anything) in him and possibly because it is a way to draw Katsuhira's feelings.

It is said that Katsuhira has romantic feelings for Sonozaki, but Katsuhira himself says that he's not sure about that and that he only thinks about her most of the time. It is later revealed that Sonozaki and Katsuhira were both Kiznaivers when they were younger and are still bound together. In episode 9, Katsuhira is seen voluntarily hugging Sonozaki and stating that when he hugs her, all kinds of feelings swell up inside him. Sonozaki is seen questioning this.

At the end of the series, it is noted that Katsuhira is in fact in love with Noriko and regained back all of his pain and emotions after Noriko had released them. They are both seen in a hospital where they talk and reconcile, and almost kiss before Chidori and the others interrupt them. In response to Chidori freaking out from this sight, Noriko says their relationship will start off pure unless Katsuhira supposedly pushes her to the ground one day. 

Chidori TakashiroEdit

Chidori is a very close friend of Katsuhira, being with each other since pre-school. Despite the fact that he was oblivious to her love for him, which was unrequited, he has shown some form of care for her a few times. Due to being unable to realize her feelings for him and the initial jealousy that began to form as he focused on Sonozaki, he tends to end up mistakenly hurting her a great deal. After coming to terms with things, they have kept their friendship still going strong at the end of the series with Chidori even commenting on Katsuhira and Sonozaki's new relationship, stating she was okay with such a thing but only if they kept a pure relationship due to their current ages.

Yoshiharu Hisomu Edit

When Hisomu is first mentioned in episode 3, Katsuhira states how he feels sorry for Hisomu and starts feeling the want of having a connection with another person. Katsuhira soon realizes while the Kiznaivers are chasing Hisomu that he probably won't talk to them unless only one person like himself went to him. Katsuhira goes to meet with Hisomu, who asked if he could die for him. Later in that scene, Katsuhira causes Hisomu to bliss out after jumping off a bridge into oncoming traffic..

Later in episode 5, it is shown that Hisomu was trying to hurt Katsuhira purposely, after asking him if he could hold the firewood he was chopping or if he could sit underneath it. Hisomu also states that he is especially happy to meet Katsuhira, hinting that he has a certain interest in Katsuhira.

Through the later part of the anime Hisomu and Katsuhira show a close friendship and deep trust in one another, similar with Tenga as they both have lived together or as it suggest in the show.

Hajime TengaEdit

From the start of the anime Tenga has always shown close friendship with Katsuhira such as saving him from bullies in ep1. This continues throughout most of the show up until ep10 where Tenga is frustrated at Katsuhira‘s confusion when the Kiznaivers begin to be able to hear each other's deep thoughts, this is because of Tenga’s love for Chidori. However, after this, they soon revert to being friends in later episodes.

Nico NiiyamaEdit

These two seem to have a budding friendship. In episode 4, Nico gives Katsuhira the green peas she doesn't like. In episode 5, she protests to the fact of Katsuhira getting hurt by Hisomu. In episode 10, Nico, Katsuhira and Hisomu decide to stay friends even without their bond.

QuotesEdit

"Yare Yare Daze.."

"Even if I don't have feelings, I can still think. Even if I don't have pain, I'm sure I can still connect."

"I'm indifferent when it comes to connections with others. I think that's probably because I'm not interested in myself."
