Sato Takaya (里 高屋 Takaya Sato) is a freshman and Banri's friend.
He has short black hair and wears glasses. He is near sighted.
Sato Takaya dislikes "Real Girls" and prefers "2D women" over them, which creates his nickname "Nijigen" (二次元) which literally means two dimensional around his peers. The nickname was created during a club welcoming party where he declares that he would live in the two dimensional world after stating his despair of the real world. After befriending Banri and having the chance to talk to "Real" women such as Linda and Koko, his view has thus changed prior his introduction to the show. It is noted that he attempts to make awful jokes to lighten up the mood at difficult times, and acts as the 3rd wheel in both Banri's relationship with Koko and Mitsuo's with Chinami.
He appeared for the first time in the party room Traditional tea club, like the others he appears to have forced entry by Shi and Sao, he then met with Banri who also be forced entry, when Banri offered and Banri refuse to drink, then they tell Nijigen and Banri to sumo match.
