It's a "harem" you might say but the MC is Alpha as fuck and the traditional dense shonen doesn't really apply to him. Also the art is amazing the artist really knows what a body in motion looks like and just reading a fight can be a real feast for the eyes. There's a chapter where it's explained why character doesn't choose a girl and it's hilarious. Also in this story the character has don't read ahead is u don't wanna get spoiled or "offended";
This manga isn't for the kind of people that wants girls to be pure and innocent like chu2, kanata or pretty much anything Kyoani slings.
