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)...

Garde asks Haruna to perform a secret technique to locate Radan. Gardo thinks that the huge evil spirit detected by Rume is Radan, and heads for the swamp with Ryuga and Rian. Meanwhile, Tatsumi (Katsuhiro Higo) is night fishing in the swamp when a bewitching beauty (Mero Imai) suddenly appears and invites him to join her. Haruna prepares to perform a secret technique, but for some reason D. Ringo stops her...
