Koume's brother came to Hanamaru Kindergarten to keep an eye on her. He absolutely adores his little sister, and goes into a freeze when she is in trouble. He was there because the school field day is fast approaching, and Koume wanted to join the footrace. He is worried she'd end last and cry. Anzu and Hiiragi had an idea: for Koume to practice. Since Tsuchida-sensei cannot fill the part of a coach, they asked Kusano-sensei to be Koume's coach and trainor.

Yamamoto-sensei thought it was a line from their favorite manga, and wished that someone would tell that to her. This led to Tsuchida-sensei thinking that she's just too unperceptive...
