Otoshina

The Heian Era was the rise of the yokai. They yearned to destroy all of humanity and claim the planet as their own. But humans who desired to master the power of the soul and wield their blades to slay evil were given the titles of "Demon Slayers"! You are one of the newest demon slayers, going to defeat an oni who was spotted resting in the Abandoned Shrine.
You believed it would be easy...but the Oni would showcase nothing but absolutely brutality...for your body and your penis...
Walk through the wide and sharp path of Otoshina--The Green Oni Who Guards the Shrine. What secrets does the strange yokai hide, and what darkness awaits her and you...?​
