In the mural of the last chapter, there was a monster on the right hand side that looks like it has Dragon’s tattoos on it.
If that is indeed Dragon’s power, I could see Teach killing him and giving the fruit to Shiryu’s sword.
Shiryu’s name has the Japanese word for dragon, Ryu, in it. And his epithet “of the rain” would make a lot of sense if he could control the weather.
Ultimately feel like this could be a viable way of making Shiryu a top tier, if that’s really what Oda wants.
