@Kanol Of course she'd still be more experienced than him, but he's still way more powerful in a way that he can just make anything she does mostly ineffective. Also he has more than mana reserves, I don't know the full extent of it cause I'm only reading the manga, but when they talked about the fact that he's creating his own endlessly expanding world and that touching on the territory of the goddess. Also yes I'm complaining that he isn't prepping for a fight to come out of nowhere. 1, he's not safe in a heavily fortified human city, cause if he loses his mask people will mistake him for a monster. Second...Tomoe, Mio, and how we lost chibi Tomoe...were all 'random' incidents. Like the danger came to him, not the other way around. So by now, with the fact that he has taken people into his protection, common sense should say "Prepare so that I'm ready to at least protect people if something random happens again" I don't expect him to become a combat veteran, but Tomoe trained all those others, she could've trained the MC to the point that he'd at least have a grasp of how he can use his powers in battle, which is honestly enough to beat almost anything, and the things it can't, probably enough to escape.
