Duel Masters - S04

This is the sequel to "Versus Revolution", picking up where the battle between the Invaders and the Revolutionary left off. It serves as the final season, bringing the "Versus" saga to its conclusion. The strange "V" mark on Katta Kirifuda’s forehead once held a hidden power, but it has since been sealed away. Though breaking the seal doesn’t seem to have a major effect, something unexpected happens-Hamukatsu, his hamster, suddenly starts talking! Even stranger, more hamsters like Hamukatsu begin appearing. Soon, Katta and his friends learn of a secret group called the "Rare Killers," whose members are posing as transfer students at their school. What connects these talking hamsters to the Rare Killers, and who are they really? The final battle is about to begin.
