Daisuke Ishiwatari, and his co-worker, Toshimichi Mori, were two guests that were featured at Anime Expo in 2009. I obtained this particular signature at Mori & Ishiwatari's autograph session on the last day of the convention. Their line was relatively short as most people were lining up for Yun Kouga instead, so, they were ok with sketches. I asked Ishiwatari for a bishounen and ended up with this sketch of Jin.
