There is so many great voice actor out there, it was quite hard to choose only one.
After thinking about it, I stop my choice on Suwabe Junichi
His the one behind the voice of Aomine Daiki (Kuroko no Basuke),Grimmjow Jaegerjaquez (Bleach), Keigo Atobe (Prince of Tennis), Undertaker (Kuroshitsuji), Worick Arcangelo (Gangsta.), and more recently Viktor Nikiforov from Yuri!!! on Ice.
He have one of the low tone sexy voice
