Oops, I Summoned an SSS-Rank Ancient Dragon God

When the mainland is overrun by monsters, magic academy student Elena summons a B-Rank merman. Betrayed by her best friend Seraphina and fiancé Sebastian, she’s framed for stealing a patronus, stripped of magic and expelled. In despair, her mother’s pendant awakens Valen, an SSS-Rank dragon. They form a soul bond. Elena trains in the monster forest, defeats her enemies, confronts beast tides, and rises to avenge herself and break bloodline prejudice.
