This is in my opinion more than anything so everyone's free to disagree but basically: 1/ the burnout, I don't think rekindle touched on it the way it should've and rad weekend is a way too important thing for Akito's character to leave it at that. 2/ his view on partnership and "why toya", since Akito is more closed for these things we haven't seen a lot as opposed to characters like An and I'm very curious, but I understand this one is more intentional and we do have some info about it from previous stuff. 3/ in some times it's been stated how vivid street is like home to vbs (this was Kohane's task under taiga's guidance), An knows quite well and Toya grew to see it too but it is said very lightly that akito doesn't really see it since he sees vivid street and everything he goes after as more of a stepping stone to prove himself (?) Vivid street is kinda on the sidelines rn but it would be lovely to bring this back somehow.

Anyway yeah that's it
