Good anime, i really enjoyed, even if i dont like the type of romance between 1 boy and various girls. The fights were incredible good, and honestly i fell for Gero at the end with his shy face. The characters are very cute and interesting, really liked the dynamic, it’s wasn’t too hard. I would recommend it, even just because it’s a very fighting anime.
