Commonly known as "Grandpa". One day, he suddenly became younger. He lives in a farmhouse in a rural area around Hirosaki City, Aomori Prefecture, with his wife Ine, working as an apple farmer.

He is set to have been born in the early Showa period and has been married for 58 years. In addition to being handsome, he has a toned body from working in apple farming.
