I honestly think they'll cut team Tangsooyuk entirely. Bam is under FUG's care, and Team Tangsooyuk is Rachel-less, which seems to be the animation team's main focus. My honest prediction is a Second Season starting on AA getting news from the guy who defeated a ranker on f21, and that mini-arc of him being betrayed by Rachel too.
Then Bam appears at the Workshop with Reflejo's team, fights team Leesoo that ignores his identity, and AA and Rak join in disguise after figuring out Viole = Bam. Team Leesoo has to win the Gongbang to rescue Viole, which happens after they defeat Reflejo and get aided by Lero ro to escape. Meanwhile Rachel fetches Emily and uses her to get around and escape. End of Season 2.
Season 3 would revolve around Hell Train entering, Hoaqin, Rachel's continued failure, and Bam's victory with the help of Yuri. Sacchi, Boro, Aka, get axed. Daniel is FUG's HT guide, and Hoaqin becomes Rachel's substitute Bam. I think even Yura Ha might get axed. Less characters mean smaller voice acting crew. When they defeat Hoaqin at Dallar Show, end Season 3.
Then all things considered, I think this might be the end of this anime version altogether. At the end of Season 3 Bam would meet Rachel and breakup with her once and for all, showing her that he is better than she is, and that she should go her own way from then onward. And that he would climb with his friends for his own motives, rainbow in the back, good prevails, friendship is happiness, THE END.
Two seasons from now, remember this prediction. Lol
