Synopsis
Touka always faded into the background at school. And when he’s summoned to another world with his classmates, that still doesn’t change! They all acquire top-rank skills, except Touka, who’s deemed a failure and cast to ancient ruins by the goddess Vicius. Turns out, his low-rank skills may not be so useless after all. Now, he seeks revenge against the goddess, and his true nature is revealed. (Source: Crunchyroll)
