Hinata Urashima also known as Grandma Hina, is the original manager of Hinata. Upon retiring so she could travel the world she entrusted Keitaro with looking over the Hinata Inn.    In the manga, Grandma Hina knew all along that Naru was the girl Keitaro promised to go to Tokyo U with. She also knew the location of the Liddo-Kun shaped time capsule Keitaro, Naru, and Mutsumi buried beneath the sandbox when they were children.[1]    Despite only appearing briefly in the manga and anime, her visits and actions have a profound effect on everyone, especially Naru and Keitaro.

Keitaro Urashima promised a girl when he was young that they would meet up again at Tokyo University in the future. Sadly, in the National Practice Exam, Keitaro ranked 27th from the bottom. Knowing his grandmother owned a hotel, Keitaro intended to stay there while continuing his studies for Tokyo U, only to find out the hotel had long been transformed into an all-girls dormitory. Through an odd twist of fate, Keitaro eventually became the manager of the dorm, beginning his life of living with 5 other girls.

When Keitaro Urashima fails his entrance exams to get into Tokyo University for the second time, he's officially an unemployed and uneducated slacker. To make things worse, his parents have kicked him out of his house. Fortunately, his grandmother owns the fabulous Hinata Lodge and has agreed to take Keitaro in as caretaker. What he doesn't know is that the lodge is actually a girls' dorm and he's the only guy around! Most guys would kill to live with five sexy ladies, but if Keitaro's not careful, this job will kill him.
