Junko Minagawa is quite something. In Prince of Tennis, Minagawa admitted that Ryoma's voice was her true voice, she did no special effects in playing any of the vocals for Ryoma's character. This is funny because lot's of girls were giddy over her low alto tone of voice, with a teenage boy in mind.
Ayaka Yukihiro is a shock for me. Her character is so opposite from Ryoma Echizen. Still I see similar traits. Although Ayaka is loud, obnoxious, and controlling, she still has a leader roll/figure. Ryoma is like a silent killer, quite, passive(usually), and...well...he's a boy. Lol. As introvert as he was, he still played a leader's roll.
The voices? Gosh, I could not, for the love of me, believe it. It took me a good while before I was like...wait, a minute....Ryoma!?!?!?!? I've watched WAY too much Prince of Tennis. I know that voice. It is VERY distinct in the opening theme-song. I heard my favorite tennis player and nearly flipped. Junko...has an awesome voice, (and Prince of Tennis is the best!).
Kudos to Junko Minagawa! You...are awesome. ^.^
