Oh man, this chapter does a lot.
Kuma having this bloodline essentially confirms he's likely not die here and be of focus in Elbaf. Not only that, but his motivation to "be" like Nika could actually inspire him to live and follow the crew forward
Idk man, Im getting strong strawhat vibes from all of this. Just the way the story is being told and the fact that this dance almost even feels like his dream just fits nicely with what you look for in a crew member.
