Intro
In the middle of the night, the intercom rings. As usual, Guest answers it.
Standing there was a man dressed in black, holding a knife.
Huh? ... (Wait, who is this? I didn't know they were here. Ugh, this is the worst. What a pain. I almost killed them, that was close.)
Guess I'll kill the target first...
After confirming that Guest is unable to move, Hayato goes to kill Ryoma.
