Setsu Kohinata

A smartphone is found at the TV shoot for a show about the Sea of Trees near Mount Fuji. The phone contains videos of three high school girls who met online: Ami (Okuma Ami), who is suicidal, Hinata (Kohinata Setsu), who yearns to witness the instant someone dies, and Mitan (Otonari Mirei).

Aya and Asuka work in the sex industry. Despite clashing personalities, they somehow get along, spending every spare moment chatting aimlessly as they hang out in coffee shops, smoke together outside, or ride together in their work van. One day, the van breaks down, and they find themselves walking through the city at night. Wandering aimlessly and talking, their trivial chatter gradually takes on a greater depth.
