Intro
Haru and Guest arrive at the masquerade ball.
To ensure their identities aren't revealed...
One wears a cat mask,
The other wears a fox mask.
"Help me, please, don't leave me behind!" Someone is startled by the sound of your screaming cry. "I messed up." Oh dear, oh dear, who did this? It's that guy's fault. It's so helpless, it's sickening. Oh dear, oh dear, a knife has been plunged. Back then, who was it...? It's the start of a mystery. Who was the killer? Face the venue. They're in here somewhere. That person with the scent of blood... Even if I die, I'll find them...!!
