An confesses to her feelings by running away. Kibou confesses to her by showing her the future they already had. The entire show is about a girl realizing love isn't something you choose in a single moment, it's something you become over a lifetime. A single episode that somehow does more for romance than most series do in twelve.

When her childhood friend Yuuki tells An that his family is moving away and confesses that he wants them to date once he returns, she panics and runs off. At the castle entrance she finds a portal, steps through, and lands fifty years in the future. A young man named Kibou and his robot rabbit butler offer to show her around a city full of modern technology and flying personal robots. Along the way Kibou reveals that An is his grandmother and Yuuki his grandfather, and tells her she need not feel so uncertain about what lies ahead. The single-episode romance and sci-fi ONA was made to promote tourism in Ogaki City, Gifu Prefecture, with a script by local novelist Kou Nakamura.
