12 year old Sasshi Imamiya and his best friend Arumi have always lived in the Abenobashi Shopping Arcade, until a series of freak accidents closes it down and propels the two boys into a seemingly endless parade of alternate worlds, where the shopping arcade, albeit vastly changed, is the only constant. Can the two boys catch the little demon that seems to offer a way home? With the Abenobashi now closed, do they even want to return? With a self-referential approach to other forms of anime and an off-beat humour, this contains the first four episodes of the series. Episodes are: 'Mysterious!'; 'Adventure!'; 'Combine!' and 'Blaze!'
