While on the road to their field trip, Class 2-C's bus is enveloped in light, and the Goddess, Vicius, summons the students and their teacher to another world. The Goddess hopes to raise them as Heroes to defeat the Great Demon Empire, and she welcomes the students after appraising their abilities with her crystal. However, Mimori Touka is appraised as an E-Class, the lowest rank... and he's branded a trash hero.
This feels more like a cave
 than a set of ruins.
‫هذا كهف أكثر منه إلى أطلال.
Das sieht weniger wie eine Ruine
als eine Höhle aus …
Más que unas ruinas, parece una cueva.
Más que unas ruinas, parece una cueva.
On dirait plus une grotte
que des ruines.
Sembra più una caverna che un ammasso di rovine.
Isso parece mais uma
caverna do que ruínas.
Больше похоже на пещеру, а не развалины…
