C15. A horrible H!P concert outfit.I hated the Pyoko Pyoko Ultra costumes so muchhhhh

I think they're SO ugly...

EDIT: Ooops, just realized it was meant to be CONCERT outfit hahaha... Well, then I choose the one used during the song Ame no Furanai Hoshi de wa Aisenai Darou at the 2008 Resonant Live concert. Weird pajama-like robe that reminds me of a priest clothes, but with lots of feathers O_o
