^Who knows lol, but I wouldn't get rid of him--if I recall correctly, he's one of the few performers I liked. Dressed in a silly way though.
Honestly, I've not warmed up to most of the dancers... maybe because the choreography is weak? I've seen the "waving arms side to side" and the" waving your arms dramatically either to another dancer or the crowd" dances a million times and they're never convincing. And maybe it's just me but they also never seem quite in sync. Still, Ayu seems to like them as friends too, so what can ya do?
