I'm not sure if it's too late to give requests for this year. But here goes:
Seiyuu:
Aoi Yƫki - Madoka Kaname from "Madoka Magica", Yuuki from "Sword Art Online II", Ichigo Amano from "Yumeiro Patisserie", etc.

Musical Guest:
Yuki Kajiura - composer for ".Hack//SIGN", "Tsubasa Chronicle", "Madoka Magica", "Sword Art Online" (both series), and others.

Again, thought I should get these in while I can. It may be a little late for this year's Otakon. Plus, it may be wishful thinking. Bu
