Ishibara Yuujirou

Ishibara Yuujirou (ͳϺ) is Section U's manager. He just drinks tea or is sleeping, because he's just waiting for his retirement. He worked for 42 years and never was late or missed a day. He never gets angry. He doesn't laugh with a loud voice. He doesn't say things that aren't important. Nobody knows what he enjoys in life. He's like a hermit.

Ishibara's voice is done by Tatsuta Naoki (ζľ).
