1. The Goddess Announcing Her Summons

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)
