But their latest task is one that has seen failure from everyone who has attempted it: the subjugation of the impenetrable fortress of Doldrey.

This single event causes Griffith to lose his composure, and leads him to make a decision that will alter his and the Hawks' fates forever.

Beastar—a title awarded to beasts who prove their excellence through fighting inequality to unite carnivores and herbivores in an anthropomorphic animal society. Cherryton Academy has gone five years without one such leader. However, following the murder of an alpaca within the school boundaries, the growing tension between the different species poses a greater need for a Beastar to ensure peace and harmony. When Louis, the prime candidate for this prestigious role, rejects the offer and leaves the academy, the student council declares to honor any student who captures the culprit of the aforementioned murder as Beastar.

To further complicate his life, he struggles to manage his complex feelings for the white rabbit, Haru.

In a civilized society of anthropomorphic animals, an uneasy tension exists between carnivores and herbivores. At Cherryton Academy, this mutual distrust peaks after a predation incident results in the death of Tem, an alpaca in the school's drama club. Tem's friend Legoshi, a grey wolf in the stage crew, has been an object of fear and suspicion for his whole life. In the immediate aftermath of the tragedy, he continues to lay low and hide his menacing traits, much to the disapproval of Louis, a red deer and the domineering star actor of the drama club. When Louis sneaks into the auditorium to train Tem's replacement for an upcoming play, he assigns Legoshi to lookout duty. That very night, Legoshi has a fateful encounter with Haru, a white dwarf rabbit scorned by her peers. His growing feelings for Haru, complicated by his predatory instincts, force him to confront his own true nature, the circumstances surrounding the death of his friend, and the undercurrent of violence plaguing the world around him.
