Shinsuke's Mother, an ailing older woman with sad eyes. Appears for the first time when Jin and Mugen burst into her house looking for Shinsuke after receiving a tip, she denies even having a son. Shinsuke arrives home much later, and she tries to get him to tell her what kind of business he's mixed up in but fails. She then finds Fuu hanging around the house the next morning and assumes she's his girlfriend; they talk and Fuu bonds with her. At the end of the episode, Fuu returns to speak with her but can't bring herself to say that Shinsuke is dead. His mother guesses anyway, and says it's justice brought down upon him for having turned to crime. She weeps for her son. (Fuu later mentions in episode 12 that she wants to write his mother a letter at some point to try and explain what happened.)
