cool song and group! this is their debut
the song was composed by Seiko Oomori and the choreography by ex BiS3 member Mina (or "Chantmonkee") there isn't much info about the members yet other than the one in the "Love me" sweater is called Sakura Hamabe and the one in the white jacket is Tenka Ono
in any case just by having Seiko and an ex BiS member helping behind the scenes they already have a lot of people interested in them, looking forward to what they planned next
