Matsumoto-kun is just about to turn sixteen when he accidentally bumps into and injures his mysterious high school senpai, Mizushima-kun. Now, he is bound to make it up to him. But the lines aren't clear on just how far this new angst-filled, steamy relationship will go?

Pieces of curse fall from the sky as if to mock the cruelty and evil of humanity. These stones create wretched beasts and the blood of these beasts turn human flesh into the undead. There is only one thing that can destroy these hellish fiends - Jade Stone.
