He soloed what? Akaza was in full control during the entire fight, and was just toying with Rengoku because he wanted him to become a demon. Gyutaro is also far more lethal to demon slayers, one single scrath is enough to kill anyone. He doesn't even need to fight, he can just run and hide

Akaza was introduced in Mugen Train as Upper 3. That tells you hhow strong Rengoku was, he soloed a upper 3, while a team fought two uppers 6's. Wild shit.

Allona, Nezuko's blood demon art is able to burn only others demons. There was poison in Gyutaro's blood, so Nezuko managed to burn it. However, she doesn't have healing ability.
