NTR Childhood Friend Asuna

NTR Childhood Friend Asuna is a Japanese erotic adventure game based on the popular gacha game Blue Archive. In this fan-made production, the player controls Asuna Ichinose (renamed Asuna Nanase for copyright reasons), a beautiful student whose good looks have made her the target of her perverted teacher, Hanada. After being cornered and drugged by Hanada, Asuna wakes up in a basement which has been converted into a "hypnosis room" to brainwash her into becoming his sex slave. She only has a limited amount of time to overcome Hanada's traps and escape before she will succumb to the hypnosis and become his slave forever.

The player controls Asuna as she explores the basement and solves multiple-choice quizzes and puzzles that will help her escape. Falling into one of Hanada's traps will trigger a sex scene. The amount of times Asuna is caught in a trap will determine which ending the player gets.
