Itsuki's Parents

Itsuki Takeuchi's Parents. Neither of them have been named and very little is known about them. Itsuki's father drives a FWD automatic diesel car, which Itsuki shows distaste for by calling it "antique". Itsuki's mother looks very similar to her son. They both appear in the Extra Chapter: Takumi Side Story

History
Itsuki brings Takumi round to his house on his 14th birthday, as Takumi wishes to be a delinquent as he thinks his father, Bunta, doesn't love him. They have a large meal, and Itsuki convinces his father to let Takumi have some beer, which Takumi finds bitter. Mrs. Takeuchi tells Takumi that he is mature for helping out with the family business, commenting that he's very unlike Itsuki. When Takumi insists that Bunta doesn't care for him, she laughs it off, and insists that he call his father to tell him where he is. At 5AM, Mrs. Takeuchi lets Bunta take Takumi home.

Itsuki later tells Takumi that he thinks his father's car is antique, after Takumi suggests he borrow his family's car instead of buying his own.
