"Beastar"—a title bestowed upon creatures who demonstrate their greatness by combating inequity in order to unify carnivores and herbivores in an anthropomorphic animal community. Cherryton Academy has been without a leader like this for the past five years. However, following the murder of an alpaca within the school grounds, the escalating tension between the various species necessitates the presence of a Beastar to maintain peace and harmony. When Louis, the leading contender for this coveted position, declines the offer and leaves the academy, the student council proclaims that any student who apprehends the perpetrator of the aforementioned crime will be dubbed Beastar. Meanwhile, Legoshi's feeling of duty as a powerful wolf tasked with protecting the vulnerable drives him to investigate the occurrence. To make matters worse, he is unable to handle his finances.
