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...

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!

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.

Majima Takahiro welcomes his former assailant, now given the name Gerbera, as his third servant. With Lily and Rose still recovering from their ferocious battle, Takahiro begins exploring the forest alone with Gerbera in hopes of finding more monster companions. But he has a mountain of problems weighing on his shoulders, from ensuring the safety of his group to improving the strained relationship between Rose and Gerbera. Not to mention he still hasn’t figured out his own relationship with the human Katou. On top of all that, now Takahiro has to decide whether to change course toward a potential human presence Gerbera informed him of or continue struggling through the dense and dangerous forest in this unfamiliar world.

The monsters seem to think so!

The new girls of the Tamers Committee are coming into their own as monster caretakers, yet the monsters remain ever mysterious.

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?
