Some mild innuendo. Sensei is seen repeatedly trying to look up a figurine's skirt.

A brief hot springs scene shows the top of a girl's breasts (no explicit detail).

Various moments of fan service throughout the show. One of the main characters has large breasts. One character has a fantasy about women with large bouncing breasts. One female character is shown naked in a bath scene (onsen), though only the tops of her breasts are visible.

Frequent mild combat violence, with no blood or serious injury detail.

One flashback scene shows red blood stains in a black-and-white scene (not gory).

Occasional mild coarse language ('damn', 'hell', 'ass', 'crap') in the official English subtitles. One cut-off, implied use of strong language ('fu-').

A special power called 'Cat Doping' is used, which has a hangover effect for its users the next day.
