Asahina Mafuyu is an 18 year old who is in a large Mafia group with her parents being the top leaders. She is next in line to being the Mafia Boss, and for this, she gains the name of "Little Boss" from her peers. She's emotionless and apathetic. Mafuyu likes spending time at their base's shooting range and finds subtle enjoyment in watching newbies try to join their group in initiation. She doesn't smile or smirk. Very dexterous. She isn't a fan of making jokes.
