Ino and Neko both can match for half a day
they’re both stronger in sulong by Kaido’s own words
Ashura Doji can match Ino and Jack
Denjiro is called the strongest samurai in vivre cards
so yeah, YC+
Jack also fought Inu and Neko for a longer time, both at once and also at switching between a 1vs1 with Ino and Neko
Ashura only managed to match Ino without Sulong, and he fought Jack but it ended in a draw
Denjiro might be the strong sword user, Ino and Neko being Minks, especially Sulongs, goes far beyond simply being a swordsman
