A mage, lacking both talent and lineage, is burned to death by the magic he loves. He's reborn as Lloyd, seventh prince of the Saloum Kingdom, with his past memories intact. One day, in a forbidden library, he awakens a demon that wields ancient magic...

After making the Demon Grimoire his familiar, Lloyd sets out in pursuit of a dungeon with magically enchanted items and encounters Tao, a martial artist who uses Qi techniques. Lloyd assumes the alter ego of Robert and heads deep into a dungeon with her.

Deep within the dungeon lies a demonic lich that has laid many adventurers to rest. After forcing Robert to escape, Tao faces the threat alone, but is overwhelmed by the difference in power. However, just as the lich is about to finish her off...

With an interest in weapon enchantments and their effectiveness, Lloyd joins Albert and Sylpha on a monster hunt. After meeting Tao and reaching their destination the group encounters a pack of bearwolves, who regenerate unnaturally quickly.

Just when it seemed Sylpha was able to overpower the pack of bearwolves, the demon Pazuzu emits a miasma that has the knights collapsing to the ground. Once even Sylpha and Tao are rendered unable to retaliate, Lloyd finally makes his move.

With his new bearwolf, Shiro, in tow, Lloyd visits his sister, Alieze, in order to learn how to communicate with monsters. Afterward Lloyd is reunited with another brother, Dian, a blacksmith who is seeking to create the ultimate Spellbound Sword.

The kingdom has been infiltrated by a girl named Ren from the Assassin's Guild. Upon learning of her special ability as the Poison Blighted, Lloyd tracks her back to her hideout, sneaks in, and is attacked by a group of assassins with unique abilities.
