1. Naru Narusegawa, Love Hina
Have you ever seen an anime where someone punches somebody else, and the someone else goes flying into the stratosphere, possibly trailing blood?
That’s frequently referred to as the “Naru Punch,” because she frequently employs it on Keitaro, the hapless protagonist of the anime Love Hina.
Naru administers these punches after Keitaro cops a feel, catches her naked, or she catches him with any of their other, frequently clothing challenged roommates, and just basically doing anything perverted, which means it happens several times an episode.
The tragedy is that every single one of them are accidents, and Naru is beating an innocent (although extremely unlucky) man.
2. Akane Tendo, Ranma 1/2
Akane Tendo is a practicing member of the Tendo Martial Arts Dojo, so she’s got some training in kicking people’s asses.
And while she occasionally does need to defend herself from fellow martial artists, she generally uses her skills more to beat her fiancé Ranma Saotome.
She does this because he frequently verbally abuses her, calling her ugly, a tomboy, or dumb; by generally making fun of her; or just mocking her cooking, which is admittedly terrible to the point of inducing paralysis.
This mocking/beating ritual is actually a form of courtship for Akane and Ranma, while they refuse to admit their true feelings for each other for hundreds and hundreds of episodes, so in a sense, you can say they both abuse their audience, too.
