One of two Yakuza who arrived in the Gantz room before the start of the Onion Alien mission. Like his partner in crime, he had bullet holes in his clothing, indicating that he died from gunfire. He dies his first mission out. Trivia: The internet meme face "Y U No Guy" originated from Kiyoshi's expression in chapter 55 of Gantz.
