The monster attack has left Fort Tilia in ruins. Since they can no longer defend the fortress or stay there in safety, Takahiro and the remaining survivors leave to escape the Woodlands. Their destination is the Third Company's home of Aker. Trouble follows close behind them, though. The Skanda, a cheater with overwhelming power even among the students, receives news that Takahiro might've been the one behind the monster attack. Thus she begins her pursuit, ready to bring him and his monsters to justice.

One thousand Japanese high school students are suddenly thrust into an unfamiliar world rife with dangerous monsters. Their survival becomes dependent on those who awaken to unexplainable powers. Majima Takahiro, a normal second-year student, does not get any such power. Instead, he joins the majority of students building the homestead. But when a group of empowered students revolt, Takahiro is left wandering the forest on the verge of death. Having lost all faith in humanity, he finds salvation from an unlikely source: monsters!

Escorted by the elven knight Shiran, Majima Takahiro and Lily arrive at a fortress within the monster-filled forest. There, they meet members of the first expeditionary force and Takahiro’s best friend Mikihiko. Not everything is as it seems, however. As the two of them begin to learn more about this world and its inhabitants, they must closely guard their secrets from all those around them. Meanwhile, Gerbera, Rose, and Katou Mana remain hidden in the forest. They continue to keep a watchful eye on the fortress, but an unexpected event befalls them...

Takahiro’s group finds themselves in a hopeless predicament, facing off against the Skanda Iino Yuna’s overwhelming power. But thanks to Mana’s sacrificial play, they successfully overcome Iino’s strength. However, as a result, a landslide splits the party in two and half the group is washed away by the river raging below the cliff. When Lily manages to find Takahiro and the others who were separated, yet another cheater launches a sudden attack on them. With Takahiro’s forces scattered and exhausted from the previous battle, can he fend off this mad warrior?

When giant monsters roam the earth, "wildlife care" takes on a whole new meaning. That's where the Tamers come in--girls trained to soothe the savage beasts. But while co-existence is a way of life, it's still a little overwhelming for meek Ion Hidaka. Can she handle being one of the newest members of the Tatara Girls' Academy Tamers Committee? The monsters seem to think so!

A giant army of monsters suddenly attacks Fort Tilia. Among all the chaos and death, Takahiro and Lily must decide whether to reveal their secret, and invite suspicions that they were behind the entire attack. But if they don’t act, their new friends in the fortress will be in danger! Meanwhile, the cheaters of the exploration team, Juumonji Tatsuya and Watanabe Yoshiki, prepare a counteroffensive plan to repel the invaders alongside the army. However, at the final hour, the unimaginable happens. None can peel their eyes from this development!

Let the rivalries begin. If Jackson Hunt ever wants to become a champion monster trainer, he's got a long road ahead of him. And he's not the only one with dreams of glory. As a new season of the Djinn Battle League fast approaches, Jackson prepares to enter training camp -- a grueling series of tests to discover talented new tamers. The rules are simple: if you're not the best, you go home. For a young man who lives to battle, going home isn't an option. There's only one problem -- Jackson isn't so sure he deserves to be there in the first place. With competition heating up, Jackson's bond with his Djinn will be tested to their limits. But no matter how much he trains, if his new monsters won't work together, he won't stand a chance. The fighting will be intense. The rivalries, fierce. At the end of the road, the chance of a lifetime awaits. Against friends and foes both old and new, can Jackson prove he's worthy of a shot at the big leagues? Djinn Tamer: Rivals is the second book in the Djinn Tamer series, a monster-battling LitRPG for fans of Pokemon, Digimon, and Monster Rancher.
