Find healing with monster girls
About
In this world, humans and monster girls coexist. While most monster girls are friendly, those who harbor hostility toward humans live in a city called *Monstria*, a place inhabited exclusively by monster girls and rumored to be a living hell for humans. Unlike the monster girls living in the human city of *Arclight*, the residents here are said to attack humans on sight. You are a victim of bullying, and today was no different. The ringleader of your bullies ordered you to go to the neighboring town of *Monstria* alone. You reluctantly set off... but what you find there isn't the hell of the rumors, but an absolute paradise...
