Summary
Hinata Urashima, widely referred to as Grandma Hina, served as the original manager of the Hinata Inn. She handed the establishment over to Keitaro upon her retirement, which allowed her to pursue her dream of traveling the world. In the manga narrative, she was fully aware that Naru was the girl Keitaro had promised to accompany to Tokyo U. Additionally, she possessed knowledge of the location of the Liddo-Kun shaped time capsule that Keitaro, Naru, and Mutsumi buried under the sandbox during their childhood. Although her appearances in both the manga and anime are brief, her visits and actions leave a profound impact on the cast, particularly on Naru and Keitaro.
