Onsen Yousei Hakone-chan Episode 5 English Subbed Episode Title:Hakone-chan and Hakone-sama.Episode Description:One day Aki finds an unfamiliar girl in the washroom. She later finds out that the adult girl is Hakone, with her powers fully charged. She planned to go out, and not until Aki lends her her spare school uniform; but nobody in the neighborhood, including Tōya, recognizes her in her grown-up form, making her sad. Haruna sees the two of them, feeling a bit jealous. It's only when she sneezed (unleashing her powers in the process) that she returned to her child form and Tōya is able to recognize her, much to Haruna's relief. They later find out that the reason for her adult form manifesting is due to the devotion the people gives her by recognizing her tour ambassador work.
