The more I think about this chapter, and this flashback, the more I hate it. There's nothing wrong with Kuma's backstory, it is just so dragged on and cloying it was impossible for me to actually feel sad (or anything else but boredom).Reading the entire flashback was an unending torment. Kuma knowing Nika was a rubber man, the umpteenth Zoro moment sneaked in, and the Sanji's slander right before the beginning of this SBS material flashback just made it worse.
With this said, I like Kuma and Bonney and I hope she joins the strawhats. Much better than Yamato or Carrot. Now it is Sanji time.
