Oops, I Summoned an SSS-Rank Ancient Dragon God

When monsters overrun the mainland, academy student Elena summons a B-Rank merman to stand with her. After Seraphina and her fiancé Sebastian betray her and frame her for stealing a patronus, Elena loses her magic and is thrown out. At her lowest point, her mother’s pendant awakens Valen, an SSS-Rank dragon, and the two seal a soul bond. From the monster forest to brutal beast tides, Elena hones her power, faces her enemies, and fights to overturn the prejudice in her bloodline.
