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 world ain't so bad! 
A hot wind's blowin' my way!
‫أظنّ أن العالم الآخر ليس سيئًا!
Die andere Welt ist gar nicht so übel.
Bin jetzt voll dabei!
Este mundo no está mal.
¡Voy a reventarlo!
Este mundo no está mal. ¡Voy a petarlo!
Je le sens bien, en fait,
cet autre monde !
Potrebbe non essere male questo mondo.
Sono troppo forte!
Acho que o outro mundo não é tão ruim!
В другом мире тоже неплохо!
Я аж пылаю!
