Synopsis: Wonder Rabbit Girl

Rei has always lived in the shadow of his brother, Nanami Ren. He lacks social skills, athleticism, and strong academic performance, while Ren is intelligent, well-liked, and accepting of Rei's flaws and lifestyle. However, Ren experiences a sudden mental breakdown, repeatedly screaming in terror about a mysterious character called Wonder Rabbit Girl. Seeking revenge, Rei takes it upon himself to investigate under the guise of his brother, armed with only a USB drive containing a list of the school's girls and their respective fetishes. He is convinced that one of these girls is connected to the elusive Wonder Rabbit Girl.
