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.
Well, do your best to live with what 
little time you have left, Mr. Trash Hero.
‫ابذل جهدك في العيش لما بقي لك من وقت،
Dann streng dich für die kurze Zeit an,
die du noch zu leben hast,
Que disfrutes
del poco tiempo que te queda,
Que disfrutes
del poco tiempo que te queda,
Allez, surtout, profite bien
du peu de temps qu’il te reste à vivre,
Oh beh, fai del tuo meglio nel poco tempo
da vivere che ti è rimasto,
Bom, faça o seu melhor para viver
com o pouco tempo que lhe resta,
Что ж, удачи цепляться за жизнь
оставшиеся тебе несколько дней,
