he should have done Mugen no Hane as that features the vocals of his juniors ie. A.B.C.Z & Kis My Ft 2 as I think that's a great song
& Hazuki twittered a while back ago that Kis My Ft 2 is supposedly going to debut this year
omg I hope it's true @_@ as it's really long overdue for them to debut ;___ ; & so's other bands like A.B.C.Z !
Kis My Ft 2's a mini version of KAT-TUN & Fujigaya rocks while Senga's just plain girly/silly xD
