I think the 5 Kage could win this pretty easily. Mei’s corrosion Kekkei Genkai and Katsuyu’s acid can melt any of the Animal Path’s summons. Tsunade can take out the Naraka Path pretty easily, which would prevent any resurrections. A can blitz the Preta Path and take him out so that he won’t be able to block any ninjutsu from the other Kage. Gaara and Onoki can hold off the Deva Path, Asura Path, and Human Path (which isn’t much of a fighter) while the other Kage take out the Naraka and Preta Path. Once those two Paths are taken out, the battle becomes much easier.
