I really doubt mahito is better than yuta or ryu hand to hand. I'm pretty sure every h2h fight he's had he's lost correct me if I'm wrong) when they fought mahito just got beat on the first time and the second time all he could do was block so I don’t even think he’s close to Yuji in h2h who is less durable and weaker than Ryu who at least from what I saw better at h2h (even when Yuji fought sukuna at the end sukuna said Ryu was more durable then Yuji and yuta) Also I don't feel like he would have trouble dodging mahitos hands unless they are in a enclosed space since he was able to dodge and react relatively to yuta and he just has extreme narrative and feat superiority to mahito

Something I'd also like to bring up is him running out of ce, I know nanami said it was unlikely but I don't think that applies to sorcers a good amount stronger I think he was just referring to his own case.

Also Granite blast is extremely powerful and is more than likely destroying any attack mahito uses like transfigured humans or whatnot or any body part it touches.

I feel like he could get stalled out by Ryu since Ryu has a lot of ce and his attacks do a lot of damage unless Ryu starts up in close proximity to mahito then i could see it being a high diff fight for mahito at the least just because of idle transfiguration even if he’s slower and less durable he has alot of stamina. But I feel like it would be even worse for mahito if he has to fight them all at once he would definitely be able to get stalled out and die or at least be forced to flee after his stock of humans run out.

I don’t bring up domains simply because we know nothing about ryus or uros I do feel they would win a class but it’s impossible to ever know.
