In the Kingdom of Ridill lives a genius magician known to be the first person to ever use chantless magic. With this amazing skill, Monica Everett joins the Seven Sages as a hero who can defeat powerful dragons, such as the legendary black dragon, all on her own. However, the truth is that the Silent Witch developed chantless magic due to being too shy—preferring to live on a mountain top, far from society. Her secluded lifestyle changes, though, when a fellow sage tasks her to covertly defend the second prince, Felix Arc Ridill, from attempts on his life. Unfortunately, that means she will have to go undercover as a student at Serendia Academy. Between guard duty and her social anxiety, Monica is facing her most difficult mission to date.

Joe Yabuki is a troubled youth, whose only solution to problems is throwing punches at them. What he lacks in manners and discipline, he makes up for with his self-taught fighting skills. One day, while wandering the slums of Doya, Joe gets into a fight with the local gang. Although greatly outnumbered, he effortlessly defeats them, drawing the attention of Danpei Tange—a former boxing coach turned alcoholic. Seeing his potential, he offers to train Joe into Japan's greatest boxer. At first, Joe dismisses Danpei as a hopeless drunk; but after the trainer saves his life, he agrees to live with him and learn the art of boxing. Unfortunately, Joe's personality makes him an unruly student, and he often falls back to his old ways. To survive the harsh world of his new career, Joe needs to trust his mentor and master the techniques taught to him. However, the road to becoming a professional boxer is rife with struggles that will test his mettle to the end.

Yabuki Joe is left downhearted and hopeless after a certain tragic event. In attempt to put the past behind him, Joe leaves the gym behind and begins wandering. On his travels he comes across the likes of Wolf Kanagushi and Goromaki Gondo, men who unintentionally fan the dying embers inside him, leading him to putting his wanderings to an end. His return home puts Joe back on the path to boxing, but unknown to himself and his trainer, he now suffers deep-set issues holding him back from fighting. In attempt to quell those issues, Carlos Rivera, a world renowned boxer is invited from Venezuela to help Joe recover.

The anthropomorphic animal society stands at a precipice. Following the unmasking of the carnivorous murderer at Cherryton Academy, the school introduces a new segregation policy to protect herbivores, further fueling public disdain for carnivores. Meanwhile, the black market for meat thrives like never before, and the Shishi-gumi, a powerful gang of lions, faces upheaval after losing their leader. A shadowy, violent figure emerges, intending to seize control of the Shishi-gumi with the introduction of an appetizing energy drink for carnivores. Having left school, Legoshi, a gentle gray wolf at odds with his predatory instincts, attempts to lead an unassuming life; he only uses his innate strength to protect the weak. However, his involvement with the academy's murder investigation draws the attention of the current Beastar—society's leading authority. For the sake of his controversial relationship with white dwarf rabbit Haru, Legoshi clings to his sense of justice, even when he sinks into the chaos caused by rising tensions between carnivores and herbivores.
