A brief recap of Yaiba episode 4

Yaiba episode 4 picked up the story from the ending of episode 3, depicting Onimaru fully embracing his demonic abilities. Given his motivation to acquire Yaiba's Raijinken, he ended up resurrecting eight demons, instructing some to hunt down Yaiba as well as his precious sword.
Elsewhere, Yaiba begins his training under Musashi to eventually wield the Raijinken. Although Yaiba doubts his own abilities, Musashi reassures him that believing in one's own self is the first step to realizing destiny. In the meantime, Onimaru overthrows the Japanese government, bringing the entire nation under his own reign.

Yaiba and his companions end up fighting two of Onimaru's demons, one of whom joins the former's companions as an ally. Although Yaiba manages to defeat the remaining demon, he loses the Raijinken's orb that apparently contained the sword's abilities and spirit.
Yaiba and his companions leave Tengu Mountain for the former's training to eventually defeat Onimaru, who had completely embraced his demonic qualities by that point. The episode ends with Miyamoto Musashi revealing the location of Sasaki Kojiro's sword, which also happens to be a demon sword similar to Onimaru and Yaiba's.
Yaiba episode 5: What to expect
Yaiba episode 5 follows the actual consequences of Onimaru overthrowing the government and simultaneously becoming the sole ruler of Japan.
Given that Yaiba still cannot wield the Raijinken at all, the next few episodes will follow him trying to tame the sword's spirit in order to become a capable enough opponent for Onimaru.
