The Boy and the Beast plot recap, spoiler-light
After losing his mother, young Ren flees into the streets of Shibuya and accidentally crosses into the Beast Kingdom. There, he meets the gruff and lazy warrior Kumatetsu, who needs a disciple to qualify for the grandmaster succession. Kumatetsu names the boy Kyūta, and after a rocky start, they develop a strong bond of mutual mimicry and training.
Years later, a teenage Kyūta discovers a gateway back to Shibuya, where he befriends a student named Kaede and reconnects with his biological father. Torn between his human identity and his beast upbringing, Kyūta experiences a dangerous emotional void within himself. During the succession tournament, Kumatetsu defeats Iōzen with Kyūta's secret encouragement. However, Iōzen's adopted human son, Ichirōhiko, is consumed by a similar darkness and severely injures Kumatetsu with telekinetic fury before vanishing.
