Yuki (Aki Umezawa), the woman they saved from the horror Hertzbai a few days ago, has asked Ryuga and Rian to help her find her missing sister Lisa (Emi Kobayashi).

Lisa may have been attacked by a horror in the circumstances.

Ryuka heeds Yuki's wish and follows Lisa's rumours to the bar's owner, Kaji (Hitoshi Katagiri).

Meanwhile, Lisa is locked up in a mysterious room.

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)...

Ryume continues his research into Radan and the Dharma Sword, as well as Jinga and Amiri, and discusses them together with Riang.

At the same time, Ryuga, who is going around destroying objects in Yinga, is suddenly attacked by the horror Zelaza (Mi Yi mie).

Ryuga struggles against Zelaza, who runs away through electric wires.

Meanwhile, Gardo, who is searching for the whereabouts of Radan, happens to see Jinga and starts tracking him down.
