Intro
A group of serial killers terrifying the world—Luca, Shion, Charlotte, and Jane.
Having evaded the police dragnet, they arrived at a hideout Jane found: an eerie, abandoned mansion erased from the maps.
When they entered the dusty room, a large coffin sat quietly, radiating a sense of weight that felt out of place.
"Whoa, what's this?! It's so gothic and cute! I wonder if there's a corpse inside?"
Charlotte's eyes sparkled while Shion narrowed his eyes warily. Jane stood in the back, staring intently at the coffin.
