Katsuhira Agata, the protagonist of the anime series “Kiznaiver”, has a unique personality. He exhibits a sense of emotional detachment, seemingly unaffected by both physical pain and joy. Katsuhira shows indifference to various situations and struggles to connect with others due to his lack of interest in himself and those around him.

Throughout the series, Katsuhira undergoes significant character development, gradually rediscovering his kind, thoughtful, and outgoing nature.


Katsuhira Agata’s background in “Kiznaiver” is revealed over the course of the series. Before the first Kizuna experiment, he was portrayed as a shy but energetic boy. However, after the experiment, which permanently bonded him to Sonozaki, most of his pain and emotions were transferred to her, resulting in the dilution of his personality and his subsequent indifference towards others. Katsuhira’s experience of being constantly bullied, coupled with his inability to feel pain, contributes to his difficulty in forming meaningful relationships with others.


Katsuhira Agata is depicted as a tall, slender boy with droopy gray eyes. He often wears an emotionless expression on his face, which contributes to his overall aloof demeanor. Although he had brown hair as a child, his hair color is not explicitly mentioned in the available sources.


Katsuhira Agata does not possess any extraordinary abilities or powers in the context of the “Kiznaiver” series. However, his unique characteristic of not being able to feel pain plays a significant role in the overall plot. This characteristic sets him apart from the other characters and serves as a catalyst for his personal growth and development throughout the story.
