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.
We're lucky to get even one 
in a single summoning.
‫نكون محظوظين لرؤية شخص

Que haya uno en un solo
grupo invocado ya es increíble.
Il est déjà si rare
d’en avoir un par invocation…

Classe S em uma invocação!
Обычно большая радость,
если находится хотя бы один.
