Ezreal and K'Sante are vocalists. Sett and Kayn (the deep voice is supposed to be Rhaast, his stage alter ego) are rappers. Aphelios is instrumentalist and songwriter, his sister Alune is band manager. Yone is producer and DJ, he is also "mom" of the group)
Personally the Blooper video they made for this won me over, it's absolutely adorable. Also, can we get a hell yeah for heavily implied canon Settphel? We love a himbo and his sassy BF.
In the Kayn's part it is Rhaast rapping. The og rappers voice isnt that deep if i know correctly but since Rhaast is rapping they pitched down his voice so it sounds deep ( and i actually love this arrangement a lot ). Ezreal is Baekhyun and Baekhyun loves playing LoL and ezreal he fits the character perfect.( and EXO is my favorite kpop group im so lucky TAT). Aphelios can't sing but he had great voice ( he lost it ) but there is a song called ''Lost in Silence '' which people assume ( it is fan made so it is not canon ) it is his song before losing his voice. Yone ... poor him i just... he must handle these brats and also always worry about the cost and budget. He is so mom like really even his introduction he has the '' band mom '' fact. It fits him so well and he is producer&DJ( two brothers both DJing I hope is Yone's fate doesn't end with a single song. ) K'sante is the one singing at the bridge somehow that bridge always gives me chills. Sett is so gay for phel istg. If you listen discord calls or look at the blooper video omg their interactions, moments eveything is calling him out and im here for it. I mean in spirit blossom skinline they were somehow canon now in this too they have moments it is just feels right and im happy also his cat ears hat
They did release what each band members role is in the group. Yone is like the "dad" of the group. Not sure what Aphelios' role is if I'm honest. But I know for a fact that his sister is in the splash art and she legit has no role. lmao
Aphelios became a crazy good instrumentalist after losing his voice. He did every instrument played in the song. Alune (his sister) is the group manager.
