>>10665565>>, it would lack the emphasis that he is indeed a 10 year old genius
I think the genius bit is really overstated, Negi is just a damn fine hard worker. He's smart, no question about that, and has talent, but his talents + brains pale to other people like Asuna and Konoka who are literally just power stations or to people like Hakase who are more traditional mad scientists.
I think of Negi as an above-average kid with a lot more opportunities granted to him because of his heritage; he has access to all the right people, the techniques and other shit to make him more powerful, which others like Anya don't have.
Put another kid in his shoes with his drive and we might see a similarly powerful character.
I'm not saying this is a bad thing, it adds a bit more layered depth to his character since it doesn't use the cliche genius plot device to explain a character's growth. Because I mean, Kotaro isn't exactly a genius but he's taught Negi some tricks as well - Ku Fei, Kaede and Setsuna are much the same. They're still young and though powerful not the top league.
