Kyoto Animation streamed the Rin Matsuoka version of the second promotional video for its July television anime Free! on Tuesday. The video showcases Rin, the rival of the main character Haruka. Rin had gone abroad to train in swimming, but his personality completely changed by the time he had returned to Japan. He often perplexes his former teammates.
The anime's official website also posted a voice sample of Rin by Mamoru Miyano and two Twitter icons. In the voice sample, Rin introduces himself as a second-year Sametsuka Academy student whose specialties are freestyle as well as butterfly.

You can read the rest at the Source (it's pretty much the same bit in the first two articles I posted)

My prayers were too weak, I love that he's a tormented soul, but the shark mouth is kind of a turn off. Makoto all the way! I also fixed the icons in Rei's post.
