Habara, Kentarou

羽原健太郎

Kentarou is a highly skilled hacker who has spent most of his student years breaching various companies' systems to steal data, which he then sells on the black market. He feels no remorse for these actions, believing that the companies are at fault for neglecting their security. After Nagi saved him, he fell deeply in love with her and began assisting her in every way he could. However, Nagi restricts his involvement in major operations, fearing he might be injured or killed. Kentarou misinterprets this caution as her underestimating his abilities, so he frequently attempts to resolve incidents independently to 'prove himself to her'.
He has been close friends with Shirou Tanaka since elementary school. Despite his background as a hacker, Kentarou is the more outgoing of the pair; he openly laughed at Sakiko Michimoto while Shirou tried to restrain him. Nevertheless, Kentarou has acknowledged that Shirou is more reliable than himself and has been glad to have him as a friend.
