Kazunari Ninomiya
At the dining table, (Sho Sakurai) and (Jun Matsumoto) are looking at a floor plan. Jirō writes his name in the space of the biggest room, but Gorō crosses Jirō's name out and puts his name instead. They continue to fight for the room until (Kazunari Ninomiya) takes the marker from them and writes his name in the space of the smallest room, puzzling the both of them.
