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.
Yasu, if you're gonna do it, 
do it when I'm not your teacher.
‫وأيضًا يا ياسو، إن كنت ستفعل ذلك،
‫فافعل عندما لا أكون مدرسك.
Mach’s zumindest,
wenn ich nicht für euch zuständig bin.
Y si es así, que yo ya no sea
su tutor.
Y si es así, que yo ya no sea
vuestro tutor.
Et Yasu,
évite tant que je suis votre prof.
Pure tu, Yasu. Fallo quando non sei
sotto la mia responsabilità.
E Yasu, se for fazer isso, que seja
quando eu não for seu professor.
Ясу, давай, если что,
при другом классруке.
