Let's say Raijuta never gave up swordsmanship and was just as good as he was before Kenshin beat him.
And Raijuta will fight against Sanosuke Sagara that has fully healed arms. The same Sanosuke at the end of the Jinchuu Arc.
Raijuta will of course have an advantage with his sword. But Sanosuke will also have a higher number of uses of futae No Kiwami because his fists will be fully healed.
Fight to the death, who'll win?
