Kyonyuu Onna Senshi Dogeza Saimin

This is an anime adaptation of the Visual Novel by Lune.

The story takes place in a Colosseum, where the world’s most powerful warriors compete in order to get first place in the ranking. However, at the bottom of this ranking is a fairly weak man who, thanks to acquired hypnotic abilities, is now able to resist all the fighters present in the arena, but also to organize sexual shows with female rivals.
