League of Legends – Japanese voiceover for Sona revealed

Announced back in October, the upcoming Japan server of League of Legends will get a full voiceover treatment for all its champions. It was not mentioned who did the voiceover for Sona, but I am guessing Riot Games are not going to be paying top seiyuus for each champion. Seen below is also the voiceover for Blitzcrank. There is still no word on when the Japan server will officially launch.
