Abenobashi: Magical Shopping Arcade (2001)

Sasshis Welt ist vollkommen aus den Rudern geraten. Seine beste Freundin Arumi ist im Begriff fortzugehen und seine Nachbarschaft soll im Namen der Stadtsanierung vernichtet werden. Doch die kleine Nachbarschaft hat eine große Überraschungen zu bieten, die sich unter dem Beton versteckt: ein Portal zu einem Paralleluniversum. Sobald dieser Abschnitt der Stadt planiert wird, wird das Portal weit geöffnet werden. Sasshi und Arumi reisen von einer fremden Welt in die Nächste. Um das Ganze noch surrealer zu machen, werden in den Welten beliebte Filme, Videospiele, Manga und Anime auf den Arm genommen.

Sasshi Imamiya is a precocious, hyper, 12-year-old boy who speaks with an Osaka accent and can be pretty.

Sasshi spends his lazy days hanging out with his best friend Arumi, having practically grown up together with her in the shopping arcade.

Arumi’s eccentric father and stubborn grandfather run a French restaurant in the Shopping Arcade known as the Grill Pelican.
