Isekai Quartet 3

Though after completing all given tasks, Tanya Degurechaff, Ainz Ooal Gown, Subaru Natsuki, Kazuma Satou, and other students of Class 2 are shocked after knowing that their time as students is not yet finished. Now, there is no way to return to their world, and these strange but funny students are trapped in some unfamiliar condition. Likewise, they grow together, so staying closer is not bad. The sudden arrival of the new transfer students erupted in funny moments and more chaos. However, their weird but somehow relaxed school life continues to no end.
