About the Game
This is a simulation-style erotic game with humorous elements incorporated. The protagonist, Kotaro Morimura, gets into trouble after sleeping with his yakuza girlfriend, prompting him to go into hiding for a while.During this period, he teaches self-defense techniques to girls at a judo dojo and starts reaching out to female students with his desires.
As a player, you will take on the role of a self-defense coach, teaching judo techniques to your students. During this time, you may encounter some dojo challenges. If your strength and skills are insufficient, you will need to earn money through simulated part-time mini-games to improve your basic attributes. This will better enable you to guide your students.
