Ahh, I thought you said he already trasnformed into his Awakening form in the manga. But yeah, I'm 100% sure Kaido is already capable of awakening his fruit.
His father was, and I'm pretty sure he learned the concept of Breath of all things and swordmanship from him.
Ryou and the Breath of all Things share the same concept but they're not the same thing. If they were either Zoro's master would have called it Ryou or Hyogoro would have called it Breath of all things. The two are from the same country afterall. There's no need to differentiate between them if...
Kaido is training Luffy obviously. Ever since he hallucinated Oden's shadow on Luffy, Kaido decided to make Luffy strong enough so he can die under his hands. It's just his suicide tendencies acting up. Someone get a shrink for this guy, he seriously need help.
