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.

The story begins with Hanabi, a sixth-grade girl who is neither an adult nor a child. She deals with issues such as accidentally witnessing her homeroom teacher kissing, and worrying about experiencing physiological changes before her friends. The series depicts a 12-year-old girl's innocent worries and first love.
