Rara Shonai

Rara Shonai is the Photography Club advisor and a teacher that first appears in episode 3 of Season 2 (although a chibi version of her appears during the ending theme of all episodes in Season 2), but not much is explained about her until episode 4. In episode 3 of Season 2, she serves as the referee and scorekeeper of Taspony matches. She had a secret plan to get the Photography Club room an air conditioner, but forgot to ask.

Background
Rara-sensei comes from Shizuoka Prefecture to the east southeast of Nagoya. She complains that Shizuoka does not have stop for the fastest bullet train, the super-express Nozomi Shinkansen.
