If the Neighbor's Club is having difficulty deciding on an action, Kodaka Hasegawa proposes that they spend their time writing a round-robin story. However, as they begin working on it, each member writes their own section of the story in their preferred style while trying to outdo one another. This results in chaos and uncertainty about whether the story will ever have a satisfying conclusion.

Boku wa Tomodachi ga Sukunai: Relay Shousetsu wa Ketsumatsu ga Hanpanai was bundled with the Blu-ray and DVD release of Boku wa Tomodachi ga Sukunai by Funimation Entertainment on August 6, 2013.
