A man appears at D. Ringo's shop asking to buy a bag.

The bag has the same mark on it as the wooden box that previously contained the Yinga object.

Ryuga and Rian begin their search using the mark as a clue.

Ryuga chases the driver (Aja Kong) carrying the crate, while Rian disguises herself and goes to the antique shop owner Danke (Lou Oshiba)...

Leaving the injured Daigo behind, Ryuga, Rian, Lume and Gardo head for Ladan. Sitting on a throne, Jinga finally brings the legendary Radan Castle back to life in the present day. The Radan Castle contains a terrifying ability that will drive mankind to despair.
