Haganai: A Round-Robin Story's Ending Is Way Extreme

僕は友達が少ない リレー小説は結末が半端ないL（゜□゜）」

Bored in the Neighbors Club's quiet clubroom, Kodaka Hasegawa suggests the members write a relay novel, each one picking up the story where the last left off. Yukimura starts, then Yozora, Sena, Kobato, Maria and Rika each take a turn, and the tale quickly spins out of control as their personalities hijack the plot. This bonus OVA is a standalone short tied to the Haganai series rather than a continuation of its main story.
