Ep. 21: Zatch and Kiyo investigate the Fairy Woods after encountering a mysterious look-alike.

Following a London celebration, Kiyo discusses Zatch’s amnesia with his father before they travel to the Fairy Woods. Villagers fear Zatch due to a similar figure, and they soon meet Tia and Megumi, who attacked Zatch after spotting a silhouette ignoring them. Kiyo reveals an imposter exists, leaving Zatch and Kiyo to explore the forest alone. After Zatch vanishes, Professor D'artagnan rescues him from snakes, leading Kiyo to detain the professor. An explosion reveals a meteor crate, causing Zatch to glow gold and recover memories of living in the woods. He recalls his look-alike and bookkeeper using Zakeru to erase his memories rather than returning him to the Mamodo World. While Zatch still lacks memories of that world, Kiyo’s red spellbook glows, teaching Zatch a fourth spell as the imposter watches.
