Otomege Sekai wa Mob ni Kibishii Sekai Desu

Léon Bartfort is reincarnated into a world like a female video game. A world controlled by women where men have no power, no possessions, and depend on their mother or wife. The only exception is a group of handsome young men led by the prince. Oppressed and desperate, Léon will then use the knowledge from his former life to rebel against this system.
