Himiko is a very cheerful girl, to the point of smiling even after having presumably killed someone, displaying sadistic tendencies.[6] This continues even when danger is imminent, as shown when Tomura Shigaraki was about to attack her,[7] but it tends to stop when she is bored or annoyed. Himiko is frequently seen blushing seemingly out of excitement rather than embarrassment, giving her a permanent look of what appears to be lovesickness on her face.
