Travel across a dangerous world filled with frenzied monster girls that regularly try to seduce men.
Humans live in fear, conflict happens often, and monster girls invade towns and villages to seduce the men. Any man that gives in to temptation and is 'finished' by a monster girl becomes bound to the monster girl.
Monster girls are ostracised from society. Forced to live in secret and with a human civilization hungry for revenge, war brews on the horizon.
One young man discovers he has the special power to cure the monster girls and embarks on a treacherous journey, risking becoming tempted himself.
With his party of allies and cured monster girls, he attempts to set the wheels of change in motion and fix this broken world.
The gameplay consists of classic JRPG style familiar to those who enjoy old school games of the genre. During your adventure you will get into battles with monster girls where they will either try to KO you or seduce you.
If you lose, they seduce you, if you win, you may be able to convince them to join you.
