Keijo is freaking fire. It's a sports manga with girls using their butt and ass to fight. And the action is as good as a fighting shonen manga, actually stellar. It feels like a parody of fighting shonen in some aspects. Even the main lead is just an oblivious girl with a feeling to Keijo. Also there are some really cool special moves like Tittihypnosis and Ass Vacuum Wave. The characters are also amazing and everyone goes through some interesting arcs unlike in the anime. Not to say the anime is better but it didn't fully adapt the story yet. My favorite is Kusakai Mio. The beautiful lesbian who ishorny for everyone and knows what girls like. This comes into play in fights too which is honestly sick explaining why she is such a prodigy. Nobody could beat her honestly. She is erotic and cool.
She made even me fall in love with her.

It is a must read for weebs that like hot girls, cute girls, action and all that jazz.
