Lag asks Gauche if he rubbed a woman's boobies but the subject is quickly dropped.

There is a running gag where Niche takes off her underwear. No nudity at all. This is rather humorous than sexual since she is a child-like god character.

Some mild bloodshed between battles with gaichuu (giant armored bugs) but nothing too graphic.

A girl cuts a boy with a knife offscreen.

Uses of damn, hell, bastard, and ass in the official subtitles.

The word "shit" is used infrequently.

Some characters are shown smoking cigarettes or pipes. One secondary character is often shown with a cigarette in his mouth.

Some characters are shown drinking alcohol in some episodes.

The Gaichu can be considered creepy for younger viewers or people with a bug phobia.
