Into the Forest of Fireflies' Light

蛍火の杜へ

Six-year-old Hotaru Takegawa gets lost in a forest watched over by a mountain spirit and is found by Gin, a masked, human-like being who warns her that he will vanish forever if a human ever touches him. She keeps returning every summer to visit him, and the two grow close across the years even as Gin barely ages while Hotaru becomes a young woman. This Yuki Midorikawa one-shot was collected alongside three other short stories.
