S01E08 - Sauvons le monde !

Asahi finds out he has to retake a cooking class, having missed the previous one. He is delighted to find out that Yōko, Nagisa, and Shiho are joining him in making curry, but soon finds out that all three girls have trouble making it. Nagisa's directions lead her to make a chocolate cake, which is accidentally tossed out a nearby window where Akane catches it with her horn. After taking a bite, she falls in love with it. Mikan decides to buy Akane lots of snacks in hopes of getting an interview with her, but Akane slips away until Akari appears to wrangle her back to the home economics room. However, both women are sickened to find that Yōko and Nagisa got too enthusiastic and added something to the curry that causes it to spew poison gas. Later that night, Akane breaks down the wall of Akari's apartment and demands that she get Nagisa to make more chocolate for her. When Akari refuses, Akane responds by magically steering an asteroid towards Earth, threatening to destroy the planet. Yōko, Nagisa, and Shiho reunite to make chocolate in the same room, but Akari discovers that the asteroid veers off course when Akane loses concentration, so she ties her down to a chair and force-feeds her chocolates made by everyone except Nagisa. Even as Akane tries copying herself to reach Nagisa's chocolate, the other girls manage to fight Akane's clones off until she loses enough focus that Nagisa's comrades in outer space force the asteroid to make a U-turn, saving Earth from destruction.
