I think he just had "raw" magic, and the spells are too complicated now. Evan has been using complicated spells from start (since he was teached when he was a kid i mean), so none of them are truly "natural", or even if you are a natural you have to refine your skills to reach full potential
Tbh I don’t get why niro is only having trouble with magic now ┑(￣Д ￣)┍ like he was such a natural before and author made him op but then it’s like he got nerfed all of a sudden just for plot or something.... like just make him work for it in the beginning then, no point in making an op chara then saying nvm...
This is just my opinion though, I still like the story and characters that just stood out to me.
P.s. neria is waifu for laifu
