in episode 5 there is a bath scene in which multiple female characters are naked, but not sexually and steam covers their most risqué parts, one missed some of their underwear which is noticed by a fellow member

Hisone (main character) is often referenced by her measurements by another character. Hisone's flight suit leaves little to the imagination. The camera often focuses on Hisone's buttocks or crotch. There are a number of veiled sexual references throughout.
