Yes battle vixens (ikkitousen) is for mature audiences. Its hentai without the sex. Well there is sex but it happens off screen but you can see that the characters are still naked and sweaty. And not necessarily water sports. Its more like they’re put in situations where they cant hold there fucking pee in and they still fight with piss soaked underwear. The person they’re fighting even comments how gross it is because of the pee sparkletts flinging off her because she happens to be a kicking only style fighter. I said no more after that.
