I Quit The Straw Hats At The Beginning And Joined The Beast Group

Time traveling into the world of pirates, Ren initially accepted an invitation to join Pirate King Luffy's crew, the Straw Hat Pirates. However, tensions arose as he consistently delivered finishing blows to weakened enemies during their journey. This disagreement led to a heated dispute with his fellow crewmates, eventually resulting in Ren's abrupt departure from the Straw Hat Pirates.

Seizing this opportunity, Ren made a pivotal decision to align himself with the Beasts Pirates, ultimately becoming Kaido of the Beasts' son-in-law and Yamato's betrothed.
