Denki is a kind, sociable and energetic boy who likes to talk to people. He is very good at making friends and is quite casual when interacting with others, including antagonistic figures such as Katsuki Bakugo or Hitoshi Shinso, although he is also not above petty complaints or overreacting if he feels sufficiently upset or shocked. Denki may seem abrupt and reckless at times, but he always means well. He is shy with his partner, but very romantic at the same time.
