Is this shota tag? I check from title that even after ch 200 MC still child. God dam 12 and helf year old! as mc saying go they will not sex until 18. Why the hell are you adding R18 then? It's the worst when bad guys fucking girls and MC don't do shit.
The main character needs weapons. Maybe you could send them to the world of Arpeggio of the Blue Steel and try to get ahold of the fog warships, torpedoes, or missiles.
Have you thought about sending him to the Sekirei world? Or at least summon the girls from there. It's a world I've never seen being explored before and the girls besides cute are strong.
being honest nothing, but after growing up with the manga I have affection for the couple and respect for kenichi in contract with komuro, also if you want to see alexander get all the girls in the series especially the daughter of ma and freya and Kenichi's sister, and even though there is nothing wrong with her staying with miu inside of me, I will not like it, I cannot force the author to do something so I can only share my thoughts, it is not to offend or annoy.
