Inamori is a blond, 20-year-old guy who showed up in the Gantz room before the Onion Alien mission. When Yamada Masashi tried to get everyone in the room to tell their names, ages, what they did when they were alive and how they died, he refused to do so. Instead, he kept asking for cigarettes. Kurono thought that Inamori had a girly face.
