Mitsuki Yamada

On the surface, Mitsuki Yamada is regarded as the top beauty of Koudan High School, but in reality she is a highly skilled ninja dispatched by the rival faction known as 'UN.' Possessing combat power capable of overwhelming the protagonist Kurou Kumogakure, she is cold-hearted with antisocial tendencies and openly displays a sense of enjoyment during fights. Despite her striking appearance, she harbors inexplicable habits such as eating boogers, making her one of the most threatening and enigmatic adversaries in the series.
