Yaiba Kurogane is determined to become a true samurai, but things take an odd turn in the jungle.

Yaiba has come up with a plan and is willing to do nearly anything to provoke Onimaru to a duel.

Onimaru now wants to fight Yaiba, but something's off, not least the horns sprouting from his head.

Yaiba has the Raijinken but it's the Thunder God that turns the tables on him. Then there's Onimaru.

Yaiba et al. head to Ganryu Island to learn about an arcane maken but end up at a shady hot spring.

Yaiba and his companions finally reach Ganryujima, where they encounter Mr. Spider — and a resurrected, but somewhat peeved, Sasaki Kojiro.

Musashi and Kojiro's duel must proceed as recorded so Yaiba can return to his original time, but Yaiba's careless comment threatens to change history.

Needing to develop a new sword technique that can counter Onimaru, Yaiba undergoes further grueling training with Musashi — and a scheming Kojiro.

Yaiba and his companions storm Onimaru Castle, but they fall through a trap into the depths of the stronghold and face Onimaru's new henchmen.

While Yaiba rides high, Onimaru tempts the young hero. And in pure Yaiba fashion, eyebrows rise.

A showdown's heating up between Yaiba and Onimaru, but the neighborhood rumor mill is even hotter.

Yaiba and team learn of an orb that promises gravity-defying powers. But an undead assassin awaits...
