A few sexual references. Nothing too horrible.

A few scenes with girls changing. Not intended to be sexual, but occasionally someone will accidentally sneak a peek.

One scene involves a girl asking a boy to put suntan lotion on her back. She then takes off her bikini top and lies on her stomach.

so was almost raped after being kidnaped

One scene two girls appear that they are going to have sex in a bathtub. But, since both were mermaids, they were trying to test how long they could remain in their human form.

A few scenes involving either mixed martial arts, swords or people punching eachother in the face (usually meant for a laugh)

A few minor swear words like "damn", "ass", and "pissed/piss-head".

Some minor insults like "jerk".

One character calls another character "A Little Shit". He is meant to be in the Yakuza, and this is meant for a comical effect.

Some minor drinking here and there.

The Yakuza might frighten some.
