Kinzaemon Kiyose

Akira Kiyose's grandfather is a character who runs an onsen ryokan called "Kikunoyu," a place that looks like it could be the setting for an anime. His hot spring inn exudes an atmosphere reminiscent of another world, providing healing and a sense of adventure to those who visit. In the anime, his onsen often serves as an important location in the story, where characters come together to strengthen their bonds and grow. The "Kikunoyu" he manages is more than just a place to stay; as the setting for heartwarming stories, it holds a special place in the hearts of fans.
