Misa

Daughter of Sai, and a professional killer working for Karasu. Misa is a teenage girl who wishes for a life without bloodshed. As the daughter of a professional killer (and protective father), Misa has trained from a young age in order to protect herself from the dangers of the world. However, as her father's work inevitably absorbed her life, Misa adapted her skillset to match those of a killer, using her youth and small figure to become the youngest and most discreet killer among her peers. Outside of work, Misa is still just a young girl. She's very friendly once she warms up to someone, and is protective of those close to her. [Taken from official website]
