Mikiya's daughter and Dougen's granddaughter. She is about 10 years old. She runs away from home after reading on Internet about her family being in charge of a yakuza organization.
SpoilerAfter that, Orihara Izaya uses her to attack Heiwajima Shizuo and involve Shizuo in his plan to help Asuki Group gain the upper hand against Medei Group (to which Awakusu-kai belongs) in their upcoming negotiation of peace. At the same time, Yadogiri Jinnai hires Vorona and Slon to kidnap her. She ends up being saved by Shizuo.
In Vol.7, she asks Akabayashi to make her stronger so that she can one day beat Shizuo. Akabayashi takes her to the gym Orihara Mairu goes to so that she can be taught fighting skills. Since her feelings towards Shizuo have become mixed after Shizuo saved her life, she sees Vorona, who claims that Shizuo is her "prey," as a rival.
