"his soul evolved: in the accelerator sleeve cap. 29 it was mentioned that a soul that has experienced death more than 10,000 times, evolves in the NT 9 othinus kills a touma an infinity of times how much do you think your soul has grown since then."

I read that chapter again and you're right. Similarly, in Railgun, the merging of the clones with the original Mikoto caused her to start transforming into a Level 6. The fact that Touma shows no signs of growth after NT Volume 9 suggests that something is keeping him from this.

"touma has several powers that we already explained that depend on how they are used vary their effects, their origins are explained from different points of view, but they are all from the magical point of view, the scientist who still does not explain it is missing, no city scientist academic has explained, "when science and magic meet this story begins" is the slogan of to aru, magic and science are found in the NT 18 when they reveal to touma that in reality magic and science are 2 separate worlds is something that I invent aliester, science and magic were finally found from that volume."

That's a good point. Touma's powers are seen as just an urban legend to most of the science side, which probably explains the lack of scientific explanations. This suggests that Aleister, who's still steeped in magic and explains IB as a magical phenomenon, is wrong like all the others who tried to explain it as magic.
