Longing to become a samurai, Usagi heads to the city of Neo Edo — where he accidentally frees a villain who was imprisoned for a thousand years.

Usagi and his friends battle Kagehito — a spider-like Yokai with multiple arms, legs and eyeballs — then must save Lord Kogane from an attack.

Gen receives treatment at the hospital as Usagi and Kitsune wind up in the middle of a disagreement between the Mogura and Bat Squadron.

Karasu-Tengu agrees to be Usagi's sensei if he captures the three Urban Yokai. Lady Fuwa launches her plan to rule Neo Edo by stealing the Ki-Stone.

The Neko Ninja Crew attacks the temple, forcing Chizu to choose a side. Gen heads over to his side job while Usagi searches for the second Yokai.

After Usagi and Chizu search for the last Urban Yokai in the Hidden Dojo, Usagi has a change of heart. Kagehito gets closer to finding his missing item.

Chikabuma sneaks away to warn Gen, Toshiko, Chizu and Kitsune about Kagehito's plan. After Usagi proves himself worthy, Karasu-Tengu agrees to train him.

Usagi reunites with the team as they battle Lady Fuwa and her ninjas. Kagehito launches a savage attack to attach the Clavis to the Ki-Stone.

The Ki-Stone fights to close the portal to would-be alien invaders but is missing an important piece. Can Usagi and the team find it in time?
