PERSONA3 the Movie #3 Falling Down (2015)

A group of teenage girls enter a hot spring (loosely covered by towels) that is currently occupied by a group of teenage boys (also covered by towels). The boys comedically try to escape the hot spring without being accused of watching the girls. One of the boys leaves his towel, (successfully) covering his manliness with his hand. Because the boys and girls are covered only by towels, some skin is revealed.

A few scenes, including a flashback, where characters are shot and killed. Every character who is shot bleeds out.

Characters take an illegal drug to suppress their Personas.
