Katsuhito Ichinose

Mizuhara's grandfather is a lively old soul, bursting with stories and a glint of mischief in his eyes. He’s got a wild shock of white hair that looks like it’s always styled by the wind, and his laugh is loud enough to echo through the neighborhood. With a penchant for colorful Hawaiian shirts, he’s the kind of grandpa who always has a classic car in the driveway, ready to go for a spin. His workshop is a treasure trove of odd gadgets, and he loves sharing his quirky inventions over tea. He’s like a walking, talking adventure just waiting to happen!
