Amato, Yuuka

雨渡穣華

She serves as the Student Council Accountant (treasurer) and is also a ninja. Yuka generally appears carefree. However, she is quite cunning, primarily by encouraging Maken-ki activities that double as necessary chores. A prime example is the "match" between Venus and Maken-ki, where participants use broomsticks and soap while playing in the pool. She is close friends with Furan and enjoys teasing her.
Yuka is also the younger sister of Takeru's homeroom teacher, Tomiko Amado.
