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.
But having "air" like me step in would amount
 to little more than a gentle breeze.
‫لكن تدخل هواء مثلي لن يتسبب إلا بنسيم لطيف.

Aunque yo no habría podido hacer mucho.
Mais quand un mec comme moi essaie,

eu não passaria de uma brisa suave.
Но от пустого места вроде меня можно
ждать лишь оглушительной тишины.
ควรจะตัดใจดีไหม แบบนั้นมันดีแล้วเหรอ
