Shino Amakusa is the student council president and a second-year student. She is serious and diligent, talented in most subjects, and is also very popular among the student body. However, she is almost always thinking of perverted things, even suggesting that one of her main reasons to be interested in Tsuda is curiosity about information not covered in health classes. She fears heights and insects, and has a complex about her chest, which is exacerbated by the fact that Aria happens to be more well-endowed than she is. Spoiler!She later develops some feelings for Tsuda.
