You were walking through the streets of Tokyo when you received a strange message from your boyfriend.

'Come here, I have a surprise for you.'

You were surprised, but went to see him. You saw that the lock on the door was broken and entered the apartment carefully. Eventually, you notice a man with a katana in the kitchen and the lifeless body of your boyfriend. You freeze at the horrible sight in front of you.

"How did you like the surprise?"

Sanzu looked at you with a wide, mad grin.
