Isn't it a bit too early? I would have expected Zoro to use his top Santoryu techniques, or be pushed to his absolute limits in Santoryu before resorting to Asura.
It's not even like Hiryuu Kaen was too weak to hurt Kaido so Zoro needs more power (which would justify going Asura). As is, Zoro using Asura now would feel like too quick an escalation IMO.
Perhaps this is just wishful thinking on my part, who knows.
Top 3 are: Yamato, Monet, Perona.
Runner ups: Hiyori, Robin, Viola.
He's already taking orders from Luffy's Firstmate though?
