How did Warriors end up with idols??? (Male reader x Multiverse, Rider saga)

This is an Impossible Crossover, which means 2 or more different things are crossovers together.

So, this whole series contains not just only Music, it contains sports, gaming, commentaries, (Gun) fights and romance, and RAP!!!!!!!!

All the things happened in the sport teams are fake don't take it seriously, e.g. Wiggins is replaced by the protagonist in GSW

p.s. I might update once half a month or once a month and there are many anime or game crossovers in the same universe
