The last Yaiba episode, titled ‘Another Maken,’ saw Onimaru’s demonic transformation give him horns and a sinister demeanor. The following day, buoyed by his previous victory, Yaiba faces Onimaru again at Sayaka’s school. Confident, Yaiba underestimates his opponent, who now wields the lethal Wind God Sword’s gust powers and easily overpowers him.

Learning that only the Thunder God Sword (Raijinken) can match this threat, Yaiba and Sayaka journey to meet Miyamoto Musashi, Raijinken’s guardian. Yaiba draws the sword from its pedestal, but its spirit seizes control until Musashi intervenes and commits to training him.
