its pretty clear he only has eyes on 1 girl.This is pretty much battle junkie manga. Romance/harem is secondary if not tertiary Bakahong
I'm kinda glad its not added because i would have thrown it into the typical harem. I really like ho a the girls have their own personalties and are super strong. Plus hear its totally about the battle junkie
So I started this under the impression that is wasn't a harem. The Harem tag needs to be added.
