>>10046191Raindrops is signed to an official record label, same as most of the current Niji's that would be picked up for a collab, so Bushiroad or any other company wouldn't be able to contact Niji directly, but would have to pay fees to license their music. Bushiroad games are unofficially "no males" too, so there really was only one of the two big companies they could've picked.
Also this isn't even the first or largest collab with Bushiroad. They literally had the entirety of Bouquet, 3 originals songs, and SSS put into D4DJ.
