A Round-Robin Story's Ending Is Way Extreme.Feeling they do not have much to do today, Kodaka suggests that everyone participate in a round-robin story, in which everyone takes turns writing a chapter of a novel. Naturally, things do not go well as each member tilts the story towards their preferences and desires. Yukimura starts the novel with a twisted love story, depicting Kodaka as a samurai who falls in love with Yukimura as a sandal bearer. Yozora fills her section with acts of Sena as an innocent girl being raped by large creatures in the middle of a street in a village. Kodaka, normalizing the story, writes that the samurai saves the innocent girl from the creatures and continues his quest into a cave to defeat the rest of the creatures. Sena, seeking revenge, designates Yozora as an evil queen of the creatures and portrays herself a goddess, who defeats the queen and rescues the samurai. Yozora intimidates Sena for writing about the queen licking the goddess's foot. Kobato shifts the story to a completely unrelated plot, in which the samurai discovers Kobato as a mysterious girl, taking her with him on his journey. Maria adds religious references, in which the samurai takes the mysterious girl into a church to be cleansed from her stench, only for her to disintegrate for being a vampire. Finally, Rika concludes the story with the samurai and the sandal bearer in the form of mecha merging together as if by making love with each other. Rika tells Kodaka that stories have happy endings once love is established. As the activity comes to a close, the club members prepare to make friends.
