She was one of Shizuka's friends and a character that only appeared in the 1973 anime. Along with her, there was another girl named Jamako. The info on them nowadays is little to nothing. It is unknown why she was scrapped in later animes. Probably, both her and Jamako were made with the purpose of filling space in the episode and its story; and to complete its 10-minute lenght.
Debuko is a chubby girl with fair skin and brown hair in pigtails. She wears an orange polo T-shirt and presumably a skirt of an unknown color, with socks and shoes of an unknown color, too.
- Curiously, Debu (デブ) means fat in Japanese, a possible reference to her appearance.
