Guess Who's Back in Town?

Synopsis

Piecing the clues together, Tyson and Kenny realize that at least two different groups are hunting the Bladebreakers' bit-beasts, which puts the retired Kai next in line. At Kai's private school, an admiring student named Wyatt pesters him for lessons, then borrows Dranzer to prove himself and is crushed by a hulking stranger, Dunga. Kai steps in and battles Dunga to a draw, and the thrill of a worthy opponent pulls him out of retirement.
