Is Yasuo Magic and could he enter Demacia?

Technically, Yasuo's power comes from a special technique which is his wind technique, not magic. Fighting techniques like Yasuo's aren't counted as using magical powers as well and that he uses standard swordsmanship.

The fact that he doesn't use mana also says he doesn't use magic.

I think there is a difference between magic and what Yasuo and others in Ionia have. Their "magic" is very spiritual, as if it is an extension of the soul/shadow/body. I think Yasuo's "magic" is more of a special technique than magic.

stop kidding with me :'(

Yasuo uses wind sword techniques, not magic... kinda... like Zoro from Onepiece

Magic people can enter Demacia, they're just weakened. Though that does make me ask why Lux can walk around so freely.

Demica the land doesnt eat magic. One very specific material only found there does. It's what their biggest city wall's are made out of, and what Galio is made out of, and I have a theory what Lucian's relics are made out of as well
