Akihabara is known as a shining beacon for otaku culture everywhere. But in a not-to-distant future, that culture is on the decline due to a mysterious affliction causing widespread memory loss. As a result, Akihabara has lost its luster. However, in one of the few remaining otaku shops, Izumi and a handful of comrades hatch a plan to restore lost memories and return “Akiba” to its former glory.
