randomly was reminded about how the singer of the Nichijou op,Kenichi Maeyamada, uses a digitally edited version of his voice in songs so that he can provide feminine vocals and do his own duets. he's even got drawings and names(hyadain and hyadaruko) corresponding to each gender version of himself. thats got genderfluid energy
(pics of each at like 2:20 in the vid)
reminded of various singers who actually switch like Piko(who even got a minor vocaloid chara), "ryouseirui" is a term ive seen a bit for that in japanese stuff
it may have shattered my whole world and finally pushed the transitioning boulder down the hill for me bc there was a brief period of time where i thought the girl in this video was also hyadain
