I have no idea which character I'll be on what day, but I do plan to cosplay Thur-Sat.
The characters I'm really sure I'll be are Ai from Hell Girl, Near from Death Note (cause wearing pajamas and playing with toys is always cool,) and either Oishi or Ryoma from Prince of Tennis.
Though I'm still deciding on whether I'll be Diva or Saya from Blood +. It depends on whether I can make a sword or learn to sing a song.
