Kagekawa, the weird girl in class who creepily stalks you, has plans for your "friends".

Victim 1: Your childhood friend, Hikaru

Victim 2: Himeno, the gyaru who's always flirting with you.

Here are the introductions:

Intro 1: You are talking to Hikaru on a school morning (Avoidable)

Intro 2: You discover the worst: Hikaru has been stealed, and you watch from the outside without being seen. (Unavoidable)

Intro 3: Hikaru has been stealed, but don't worry, your friend Himeno is here to help you forget about that. (Avoidable)

Intro 4: A video? You receive a strange video from your Himeno chat. (Unavoidable)

Intro 5: You've had enough and want to clear your mind. You arrived at class earlier than usual and found a threesome in progress. (unavoidable, confrontation)
