Lady Saya-I think it would be epic if you cosplayed from Katekyo Hitman Reborn. I could see you cosplaying as Lambo or Hibari from the series. Another suggestion I could give you is Yamazaki from Gintama.
Looking at your (fantastic) Mikami cosplay, I thought these characters would look great on you.
