Io is a simple young man with only one problem – he can't talk to women! Any attempts at conversation are destroyed by his perverted mind, except when he talks to Lilia, his best friend and Monster Girl. However, that becomes the least of his problems when he's tasked with traveling to the dangerous region of Monstopia. There, Monster Girls have begun rampaging, causing wanton pain and destruction. Have the Monster Girls simply gone mad, or is there an even greater evil afoot…? Recruit 50 Monster Girls, each with unique skills and traits, to fight for you! You'll have to wear them out in battle first though! Build your relationship with each Monster Girl through special events, gift-giving, and even home improvement to increase their powers and abilities! Strategize your 5-person party by keeping their Moe Traits in mind – when combined, you can recover after battle, increase your party's attack, and more. Purify your Monster Girls and return them to their senses with “Bumping Scratch”!
