Movie
Description
Shino Amakusa holds the position of Student Council President at Ousai Private Academy, progressing from second-year to third-year status. She presents a serious and diligent persona, achieving top academic marks in most subjects and garnering significant popularity. Her appearance features long purple-black hair, pinkish-purple eyes, and a height of 165 cm, typically clad in her school uniform.

Contrasting her model-student image, Shino frequently indulges in perverted thoughts and sexual innuendo, justifying her interest in fellow student Takatoshi Tsuda as curiosity beyond standard health education. This contrasts sharply with her strict enforcement of school rules, notably introducing Student Council Rules each episode. She harbors notable insecurities, particularly about her breast size compared to her well-endowed friend Aria Shichijō, alongside fears of heights and insects.

Her background includes prior experience as elementary school student council president alongside childhood friend Misaki Amano. Shino demonstrates domestic competence, etiquette knowledge, and enthusiastic anticipation for events like festivals, often losing sleep beforehand. She holds a specific admiration for the historical figure Oda Nobunaga. Her room contains a distinct teddy bear featuring a ball gag, a gift from Aria. A younger sister appears in later series episodes.

Shino's character development reveals evolving romantic feelings for Takatoshi Tsuda. While initially denying romantic interpretations of their interactions, she exhibits behaviors such as blushing at his compliments, holding his arm during a mall visit, and showing consistent concern for him. An OVA confirms this romantic interest, depicting a failed confession attempt. Rumors about their relationship, spread by newspaper club head Ranko Hata, persist throughout the series.

Additional details include her birthday on June 12. The etymology of her surname translates to "rain grass," while her given name carries varied potential meanings (e.g., "bamboo grass," "history," "purple"), possibly derived from the feminine version of Amakusa Shirō's name. Ownership of the teddy bear with a ball gag reflects her complex personality.
