Isekai Quartet (Japanese: 異世界かるてっと Hepburn: Isekai Karutetto) is a Japanese anime series that serves as a chibi-style crossover between the light novel series KonoSuba, Overlord, Re:Zero − Starting Life in Another World, and The Saga of Tanya the Evil, all published by Kadokawa Corporation.
One day, a magic button suddenly appears. The protagonists in KonoSuba, Overlord, Re:Zero − Starting Life in Another World, and The Saga of Tanya the Evil all press the button and move to a parallel world — another brand new isekai — where a new story featuring high school life begins.

|In the KonoSuba world, Satou Kazuma’s party comes across a big red button. Meanwhile in the Overlord world inside the Great Tomb of Nazarick, Ainz Ooal Gown receives reports from Floor Guardian Demiurge of strange red buttons randomly appearing throughout Nazarick. Megumin intentionally pushes the button and soon Ainz follows by setting theirs off as a result of accidentally sitting on one that suddenly appeared on his throne. Both series' casts are sent to another world featuring a school. They soon learn they are not alone in the new world as the cast of The Saga of Tanya the Evil were also sent to the world as a result of Tanya von Degurechaff pushing two buttons during the upgraded Elenium Type-97 experiment. Soon the cast of Re:Zero joins them inside the school as Kurt von Rudersdorf takes on the role of school principal.|

|Roswaal L. Mathers takes position as one of the school teachers and introduces the "school life" rules for the students. The students are then allowed to introduce themselves to their class peers. Later after school is over, Ainz and his Floor Guardians walk on a sidewalk when they are confronted by Aqua, who explains that she cannot allow the undead to continue and attempts to use her magic to vanquish them. She fails and is immediately hit on the head by Kazuma, who proceeds to apologize to Ainz and drag Aqua away. The next day, Aqua is punished by Roswaal for trying to start a fight with her fellow students.|

|After Roswaal tells to the class not to do anything to that threatens their school life, Demiurge explains to the class that his belief is if they try and break any rules of school life, they would be hindering their opportunity to return to their respective worlds. The class is then presented with a talent show that'll happen in the upcoming days, where Subaru explains to his series' cast during lunch that he has a good talent planned. Meanwhile, Tanya is eating lunch with Viktoriya Ivanovna Serebryakov outside when she notices Ainz and starts to suspect he might be the accursed "Being X". When class resumes, she confronts him and demands that he meets her outside of class in park after school, which angers Albedo. The two instead agree to discuss the matter now at the park while Albedo is forced by another teacher, Erich von Rerugen, to remain in class.|

|Tanya and Ainz discover in the park that they are both humans that have been sent to other worlds. As the two get to know each other better, Viktoriya arrives after class to retrieve Tanya and leave. Albedo, who spied on the two talking before they departed, becomes infuriated. The next day, Subaru and Kazuma are respectively carried by the much faster Rem and Darkness as to avoid being late to class. After seeing that they both had the same idea, both ask to be dropped but are consequently late for school, while Rem and Darkness arrive just in time. Subaru and Kazuma are punished and discover that they both have been transported to another world based on the fact that they have Japanese names. The two talk on the school roof and Kazuma becomes jealous when he finds out Subaru is surrounded with girls that are actually useful, unlike his party. Kazuma vows to become his enemy as a result.|
