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 panel by walking up there after it finished. They each signed a few items at their panel before the Anime Expo staffers escorted them outside the room. The panel was not very memorable and was probably one of the smallest panels I've ever attended at Expo. I think there were only a handful of women there, which probably says volumes about their game's target audience.
