Yamato said that the remain Beast pirates should stop fighting. They move on udon and had their Hq in Udon.
King has new clothes(Zoro cut his previous one) and even Queen clothes been not burned. They got healed and even have time to eat and drink sake. No mentioned about them handcuffs or something and if you look they don't wear any cuffs.
It is clear that Oda used them as hypetool for the upcoming event. 70 or 80% health doesn't matter, for Oda they end as hypetool to show Aramaki power.
It better to accept now since this is just the begin of Oda wanking for the Admirals. Aramaki is not her to take a L, for that Oda respect the Admirals to much. That is like BM or Kaido getting defeated in less then 10chapter and this is not going to happen.
Means Aramaki just start yet and will show soon far crazy feats and probably face off the Alliance,defeat multiple characters, if Oda really set up Aramaki to crush the party.
Anyways the point Ryokugyu made is self-explanatory and turning the entire region into a forest is nice touchu as well
Dude casually change entire region in a forest, he was not even trying. We will see his true power when he face off the alliance.
