El cierre de los servidores de Yggdrasil provocó la llegada del gremio de Ainz Ooal Gown al mundo de Danmachi. Ahora sus guardianes de piso junto con el líder del gremio se dedicarán a conocer los secretos que alberga este mundo. Mientras en la ciudad de Orario se ha vuelto implicada en un aumento de actividad por parte del calabozo, por motivos desconocidos las oraciones de Urano han perdido efecto y las muertes de los aventureros van en aumento. Los personajes de esta obra no me pertenecen.

Seven once-in-a-generation talents all apply to ANHS in the same year - rather than placing them all in Class A and having an extremely one-sided year of students, the school decides to assign these students to their own experimental class: Class-E. Despite their disadvantage in number and lack of resources like Private Points, can this small class of brilliant students climb to the top of the school? (All characters have their age altered to fit in the same year and are otherwise unchanged. Characters are taken from before the events of their anime, so Light doesn't have the Death Note and Lelouch doesn't have Geass.)
