Kabe Taijin, whose real name is Taito Kawabe, is a central character known for his exceptional skill as a rapper. His background is rooted in a difficult adolescence; as a socially awkward high school student, he struggled to express himself and connect with his peers, often feeling like an uninteresting outsider. This changed when a classmate introduced him to the music of his future rival, Sekitoba Kung Fu. Discovering rap gave him a long-sought-after medium to channel his inner emotions, transforming him from an isolated teenager into a formidable competitor. He went on to win the prestigious DRB Rap Battle Competition three consecutive times, earning him titles such as The Magician of Words, The Inventor King of the Rap World, and The Precision Machine of Rhymes.

Despite his success, the relentless pressure to maintain his winning streak took a severe toll, leading to extreme stress and a debilitating stomach ulcer. After collapsing on stage during a victory announcement, he swore never to rap in public again and retreated from the music scene, living a reclusive life. His personality is ordinarily soft-spoken, polite, and reserved, often hiding his features under a hooded jacket to avoid recognition. This shy demeanor undergoes a drastic shift when he performs; on stage, his voice takes on a tone of steeled resolve, delivering lyrics with merciless and unrelenting precision, capable of captivating an audience and stirring deep emotions.

Kabe’s motivations change dramatically over the course of his story. Initially driven by the desire to express himself and later by the fear of losing his champion status, his return to music is sparked by a chance encounter with the strategist Zhuge Kongming at a laundromat. He is coaxed into a rap battle at the club BB Lounge, where he is also moved by a performance of the song Find the Way by the aspiring singer Eiko Tsukimi, a track that held significant meaning for him in his school days. After defeating Kongming in the battle, Kabe agrees to join their mission to help Eiko achieve her dream, finding a new purpose in using his art to support another artist rather than for personal glory. His ultimate wish granted by Kongming was not a material reward, but the restored ability to rap, which reignited his passion.

His key relationships are central to his development. He forms a close bond with Eiko Tsukimi, whom he affectionately calls Eiko-chan, growing from a reluctant collaborator into a supportive creative partner and protector. This is notably demonstrated when he intervenes on stage during her concert, using his rap skills to roast hostile audience members and deflect their negativity away from her. With Zhuge Kongming, Kabe initially sees him as a strange individual but grows to respect his strategic mind, even as he remains unaware of the elaborate tactics Kongming uses to motivate him. His relationship with his former idol, Sekitoba Kung Fu, is also critical; he must confront this unresolved rivalry to find peace. Through preparation and a return to his roots with old friends, Kabe is able to face Sekitoba, and his rival ultimately concedes defeat, acknowledging Kabe’s growth.

Kabe Taijin’s character arc follows a clear path from isolated self-doubt to a reintegrated artist who values camaraderie and purposeful creation over competition and accolades. His notable abilities extend beyond his technical mastery of rhythm and rhyme. He possesses a powerful stage presence that captures audience attention and the lyrical skill to redirect crowd hostility through dissing and roasting. He is also shown to be a perceptive individual, though his innate sensitivity means he thrives with a reliable partner rather than by facing challenges alone.
