Hoshina Shuuichi

The protagonist of the main story. Average build and height, with abilities that are merely adequate across the board, though his mental agility is exceptionally sharp.

He appears to be an ordinary male student, but due to the sexual abuse he suffered in the past at the hands of his older sister and her friends, a deep-seated distrust and aversion toward women swirls within him.

However, perhaps his lack of expectations toward women paradoxically makes him appealing? Reluctantly, he tends to be quite popular with girls.

Perhaps due to his trauma, he is highly wary of those around him. Regarding women specifically, his attitude goes beyond mere disregard—he views them as little more than tools.

Consequently, even towards Erina, who harbors feelings for him, he consistently treats her solely as a means to an end.
