Hi hooo! Thx for ask.... It's definitely got my gears turning.....
I'm gonna cheat and go for 2 lol
Since I do end up preferring the high energy songs they do, something like CyAzalea Kiss/classic anisong vibes ,with a kinda color coded jacket look for the girls (like what Arisa and Anju wore for Be as One!!! To give an idea) would be great + hire Hironobu Kageyama to write the song lol

That or a more lo-fi hip hop song like R E P or even like YARUSHIKANAI from Aikyan's latest album would be peak...
