9 of Japan's leading animators were asked to create a short segment that followed the theme of "Robots," for their inclusion in this film. Essentially, this "movie" is 9 short films, all independant of one another. The common element is human interaction with robots, namely the consequences of creating life with one's own hands, played in nine very different ways. 1: Opening (Atsuko Fukushima and Katsuhiro Otomo) 2: Franken's Gears (Koji Morimoto) 3: Deprive (Hidetoshi Omori) 4: Presence (Yasuomi Umetsu) 5: Star Light Angel (Hiroyuki Kitazume) 6: Cloud (Mao Lamdo) 7: A Tale of Two Robots (Hiroyuki Kitakubo) 8: Nightmare (Takashi Nakamura) 9: Ending (Atsuko Fukushima and Katsuhiro Otomo)

The Earth lies darkened and deserted. Despite the best efforts of the film's heroine, Hikaru, the evil-filled castle of Cephiro has taken over the world and stands in the center of a lifeless Tokyo. Before the ice-witch Alcyone can take her revenge on Hikaru, she is rescued by Lantis, a young man who seals her into a magical maze where she is challenged to prove her powers while her friends are hunted down by Cephiro's warlocks. Fleeing through the silent city, Umi and Fuu must seek out the sleeping Mashin; godlike creatures that will fuse with them to form giant warriors of awesome destructive power. But the Magic Knights are afraid, untrained and alone... will even the Mashin be enough to save them from the evil acts of Cephiro?

Kazuma Satou, former NEET and current reincarnated adventurer, finally returns home after the incident at the Crimson Demon village. He is joined by his ever-reliable companions: self-absorbed goddess Aqua, one-trick pony arch-wizard Megumin, and masochistic crusader Lalatina Ford "Darkness" Dustiness. Following their recent exploits, the party is one step closer to vanquishing the Demon King and his armies—a terrifying task that Kazuma is eager to ignore for as long as possible. Things, however, are not going as smoothly as the group would like; they are constantly racking up debt, getting sidetracked during missions, and falling into traps due to their recklessness and eccentricities. As the party struggles with their perennial issues, they receive an invitation from a princess interested in hearing tales of the group's "heroic" deeds. Darkness' pleas to refuse the invitation only fire the others up to accept it, marking the start of yet another uncanny adventure with unforeseen consequences.

Sousuke Kaburaya, an impoverished detective, meets Sara, a princess from another world with magical powers. They start living together, and Sara quickly adjusts her life to modern Japan.
