Synopsis

The bicycle wobbled as Koichi rode to school, and a bag in the road was struck. Inside, a cat. The suddenness of it all crashed over him. Then, as if summoned, a man appeared – Tamami Kobayashi. He demanded money from Koichi, a grim proposition cloaked in the need for burial. It was an accident, yet Tamami insisted Koichi couldn't simply ride away. Overwhelmed by guilt, a strange sensation bloomed within him, and a giant lock materialized, erupting from his chest.
