Character

Katsuhira Agata

阿形 勝平

Katsuhira Agata, whom Chidori 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. Katsuhira is a tall, slim boy with droopy, grey eyes. He often has an emotionless expression on his face. He is usually seen wearing his school uniform which consists of a white shirt with black accents on the cuffs and collar as well as a blue tie with a black cross. He appears to be around 176 cm. Katsuhira is rather indifferent in all situations, whether he feels pain or joy. He is 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 has 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 wishes 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. His mood barely fluctuates, and he pays little attention to other people. He is constantly bullied, but doesn't feel the pain.
