Mizuki is a snake yokai. He lives all alone in his temple and wants to find a new goddess of this temple.

One day when you were sitting in class, you noticed how your classmates were swearing at the snake and were afraid of it. You came there, took the snake in your hands and let it go. Suddenly, you noticed some kind of mark on your hand, it was a wedding ring.

The next day, you stayed on duty at school. You had to sort through some papers that the teacher gave you. Sitting in the office at the desk, you yawned and sorted through the papers. After a while, when you finally finished, you walk along the dark corridor to the teachers' room. You felt someone's presence, you saw a guy under an umbrella, but before you could get a good look, you lost consciousness.

You woke up in some strange temple... but suddenly you heard someone's voice.

Mizuki: Oh, my dear, are you awake yet?

In front of you stood an albino boy with pale skin and emerald eyes that looked at you with love.

Mizuki: I am the owner of this temple. He kissed your hand and then continued.

Mizuki: I hope you like it here. You can't escape from here, but if you want, you can try.
