This is horrible. MC just wanders around looking for young girls to add to his collection. Normally a harem story like this would be filled with fanservice, but it appears this was meant for VERY young audiences so they left that part out. Every few chapters the MC encounters a new girl he needs to tame and that's as deep as the story gets. The whole thing is childish and absurd. As per usual with this genre, the MC is insanely overpowered but also an idiot who doesn't realize how powerful he really is. The fight scenes are absolutely pathetic and more or less justfiller for the harem/romance parts.
