The protagonist has gotten lost in a world full of NPCs, and decides the best way to spend time is by having sex with everyone.
Made with RPG TKool MV, however, there are no battle elements.
The game takes place in the same world as circle nome's previous work,
but there are no connected plots, so can be enjoyed as a standalone product.
Some events won't trigger simply by talking to NPCs.
