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.
Guess that's the difference 
between you and me.

Eso es lo que nos diferencia a ambos.
J’imagine qu’elle est là,
la différence entre nous.
È questa la differenza tra noi due.
Acho que essa é a diferença entre nós.
Наверное, в этом и разница между нами…
