This series has an abundant amount of fan service

A brief scene of fully-clothed male-on-female masturbation as well as cunnilingus in either this series or its sequels.

Lots of upskirt shots and nude breasts and butts. Usually shots are looking up so either the girls' panty crotch or back is visible.

In one scene a girl is seen pulling her panties out away from herself to look in and pulls out a coin.

Lots of fighting, some blood.

Offensive language is semi-frequently used.

Many characters smoke.

The violence and misogyny might be off-putting at times.
