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.
However, suddenly dealing with them on the 
spot often comes as a shock to other heroes,
‫لكنّ التعامل معهم في الحال فجأة
Aber als wir sie an Ort und Stelle beseitigten,
erlitten manche Helden einen Schock
Pero hacerlo ante el resto de héroes
Pero hacerlo ante el resto de héroes
Cependant, le faire sur le coup
laissait des autres héros sous le choc
Tuttavia, disfarsi di loro subito sul posto
No entanto, descartá-los
repentinamente com todos no local
Но если устранять прямо на месте,
เวทผสานเขตแดนระดับห้า!
