if we're being 100% self-indulgent here viskei is my answer. joyful heart maker is literally one of sidem's best songs like. Ever in general we need MORE hard rock hxj so why not just take it all the way with viskei!!! or maybe even metal!!!! let em rebel!!!!

If we're talking what's a bit more realistic though than. maybe something jazzy...idk I really think sidem needs to start playing up hxj's playing card theme more cuz their music tends to focus more on the season theme but the playing card theme is SO SO SO good but it's mostly just tied to their aesthetic so like...a whole song based on the playing card theme!!! like with a symbolic title and lyrics and everything (and also a cool af set of outfits based on the cards would be nice) idk I just hope that the next cd series does something like signal and lets the units all do something a lil different...please...I need to see HxJ do as many genres as possible!!!

I just want them to get more hard rock music tbh JIOFPERJGPOIWRJHPOIJRTOJRPTHOIJTPO

OR If we're being SUPER duper self-indulgent. kimidori from ml music. give me hxj versions of Both retale and pan to film NOW bandai namco it's the least you can do for me after everything
