Why is Kaido asking BM for a DF instead of getting one himself
Strong Rookie outclassed by every top-tier around him, trying to survive/sticking with stronger fighters.
If this theory is correct, we should see a lot of God Valley from Kaido's perspective.
I think Kaido is Harald's son with an Oni, and that Harald went to God Valley because of Rocks/humanitarian stuff.
Really interest if Kaido ran into his Dad on God Valley.
I think Kaido's Mom was the Oni Queen (Yamato is Oni Princess) who lived on a Sky Island that broke off from Elbaph during the Void Century War. Since they had less resources, they shrank in size, until they were more Kaido/Yamato sized, rather than Loki sized.
Harald met Kaido's Mom on a Sky Island, but couldn't find her again, because the Sky Island had no Log Pose, and drifts around aimlessly.
Kaido got to Vodka Kingdom by falling from a Sky Island, IMO: whole family loves skydiving.
