The protagonist (you) returns to their rural hometown due to certain circumstances... But in that village dwells yokai called "Colorlust Oni," who drain the life force from men!! Resist their temptations and cut down the oncoming oni!! Not all situations involve male submission (90% male submission, 10% female-dominant/female-receiving). - There are no romance elements for the heroine.

There are two endings, which branch depending on your choice in the epilogue. - This work is not primarily a reverse-NTR story (though there are some reverse-NTR elements).
