So far, Fanime only has one guest that I'm interested in (Satomi Sato) and she is (sadly) not enough to make me fly all the way from the East coast for... So hopefully you guys will be able to invite at least 1 more from my long list of 40+ guests to make the trip more worthwhile!!
Studio TRIGGER - This is a no-brainer. Super popular panels. I went to other conventions that hosted them and they always bring great crowds. (I would love to see Sushio or Yoh Yoshinari but any TRIGGER staff is fine with me

)
Minako Kotobuki - Voice Actress. Since you're bringing Ritsu from K-On, can you also bring Tsumugi? Pretty please

She also voiced Natsu in Baby Steps and Asuka from Hibike! Euphonium.
