there was a poster that showed Ashs rivals for the league and Kaki isn't on there. So I guess they dont fight which is sad coz they also seem like rivals and I actually thought they would battle since the scene before UlaUla (league was mentioned and Ash and Kaki were fired up, so i thought they would battle in the future event)
I have nothing against his rivals here, but 3 of them only had a bit screentime. Kaki would have been better coz then he has someone that not only appeared for like 1 or 2 episodes.
They are all official characters, so it's not like Tyson or whatever, but they really didn't had that much time in the anime BEFORE the league (kinda like his last-minute rivals in OS and AG) and now are his rivals here. I mean, it's better than original characters just made for the anime, but i just wanted to point that out.
i just would change Ilima for Kaki because Ilima had his last episodes last year february(?) and is now back for the league.
Though they kinda foreshadowed that they would battle back then, but I at least wished he had more screentime than just his episodes back then
