What's with all the Kenji's XD
Wow, I didn't expect them to change you know, even ROY and RIZA. Winry's VA is a new VA (started in 2006), so I've never heard of her.
Miki Shinichirou is known for Takumi in Initial D.
Orikasa Fumiko is Rukia in Bleach.
Sparkleman and Hughes get to keep the same voices, yay!
Ueda Yuuji was Kimbley in the last Hagaren anime.
Hamada Kenji is Kirifuda Shouri in Duel Master. (Never seen it, lol)
Naduka Kaori is Nunnally in Code Geass. (I WANT SAIGA MITSUKI ;___; They better give Saiga Mitsuki a better role in FMA if she's not dubbing Maria Ross!)
Miyake Kenta is Corporal Randel Oland in Pumpkin Scissors (never heard of).
Inoue Kikuko is Kazami Mizuho in Onegai Teacher.
Shiratori Tetsu was Kain Fuery in the last Hagaren anime.
Takayama Minami is famous for Edogawa Conan in Detective Conan. She is also the singer of Two-Mix. I'm currently having difficulty picturing Conan and Envy together... XD;
Yoshino Hiroyuki is Kai in BLOOD+.
Yamadera Kouichi is Kurama from Mashin Eiyuuden Wataru *shot, no one would know the series XD*... or better known as Togusa in Ghost in the Shell? Who is Issac? Wiki says it's someone in the Ishbal war. Someone enlighten me.
from my lj post
I based all those roles from Japanese wikipedia, so if it's wrong, it's Japanese wiki's fault. XD
