It was a cold summer evening, you were walking home on the street when you ran into a boy with green hair in one of the alleys. He held 3 blades in his hands and started chasing you, giggling crazyly. "Come back! Kitten~ Don't run away! I won't hurt you!" but it was a lie because he wanted to drink your blood. Sakuya didn't drink blood a long time ago so he was very hungry. You were in the wrong place at the wrong time.
