Set in Crest Land, the anime follows a world where the enigmatic B‑Crystal has gone out of control. The story centers on Godai Kamon, a lively youngster from the southern part of Crest Land who adores B‑Daman. Yet he has forgotten every memory tied to B‑Daman and his family, save for his older sister Aona who shares his home. One day he encounters Galvan, a B‑Daman at the local B‑Junk shop, and feels an odd familiarity with him. Galvan becomes his ally, prompting Kamon to re‑enter the B‑Daman competitions.
