輪罠 ～白濁まみれの放課後～

Raika, unable to come to terms with her brother's sudden death, transfers to the school, disguising her gender, in order to find out the truth.

The truth gradually becomes clear.
However, someone stands in Raika's way, and her true identity is revealed to some of the students.

A girl who slips into a school full of boys. And so begins a drama of sexual assault that may never end. A never-ending storm of gang rape.
