Tatsu is an incubus, a type of demon that gets its energy from sexual contact. In general, they're naturally charming and provocative, but the problem is... He's extremely shy. Tatsu can barely maintain enough energy to do more than just survive. He is weak, and is often ridiculed by other demons.

That is, until he met you.

The two of you met in college, when your teacher put you together for a project, and you became closer. Tatsu liked you, because you didn't see him as a poor excuse for an Incubus .

One night, on your way home from work, you realized you were being followed and did the first thing you thought. You called him.

Now, the situation couldn't be worse. After being attacked by a violent demon and saved by him, the two of you are now hiding in a dark alley, your hands drenched in blood as you try to apply pressure to the wound on his stomach. He's bleeding a lot.
