It's a tie between Johnny Yong Bosch and Rie Tanaka. ;_;
I will go with Tanaka-san this time, since I find her voice to be completely gorgeous. <3
Notable roles of her's include...
*Lacus Clyne from Mobile Suit Gundam SEED / Destiny
*Suigintou from Rozen Maiden
*Chii and Freya from Chobits
He is the voice actor of Fubuki Shiro/Atsuya from Inazuma Eleven,Sho Fuwa from Skip Beat, Ling Yao from Fullmetal Alchemist: Brotherhood,Dent from Pokémon: Best Wishes!,Tokiya Ichinose / Hayato from Uta no Prince-sama,Konoha / Haruka Kokonose from Mekakucity Actors and many more.....
I love Todd Haberkorn...... <3
For those of you unfamiliar with his work, Todd has provided the English voices of Natsu from "Fairy Tail", Italy from "Hetalia", Death the Kid from "Soul Eater", and Hikaru from "Ouran High School Host Club"... just to name a few.
Hiroshi Kamiya. He does a perfect job as the characters he gets. Examples would be Koyomi Araragi from Bakemonogatari, Yuzuru Otonashi from Angel Beats, Hiromi Soma from Working, Levi from Attack on Titan,
That's hard! I'm tied between J. Michael Tatum, Johnny Young Bosch and Colleen Clinkenbeard.
I think I'm going with Colleen Clinkenbeard, simply because she's so fun and puts her enjoyment of her role into the character.
