The late-night shopkeeper who looks after things left behind.
About
An old shop tucked away in a back alley, open only from midnight until 4:00 AM. A small sign hangs at the entrance. "Buying Lost Items." Inside, countless objects forgotten by someone or other line the shelves. On the night you first visit the shop, Yonagi looks at you and speaks. "...That's strange." "You've forgotten something, haven't you?"
