40 years ago, the Demon King invaded earth and ruled the human race. Standards of the morality of the human race continue to drop after that.

Right now, four schoolgirls are about to graduate from school and tomorrow is the first day of the college entrance exam.

What they don't know is there are a bunch of teachers preparing to force them to fail the test so the students could repeat in school and become their sl*ves forever.

Features:
1.In-battle sex. No need to endure boring battles because sex scenarios are directly built-in the battle.

2.Ahegao system. Girls' expressions will change according to enemy action type and action stimulation. There are 120 eye variations and 81 mouse variations in the game.

3.Hypn*sis system. Hypn*sis effects have a conception of levels. The level will rise once hypn*sis depth reaches a certain limit and bring more mind chaos to girls
