Peruru shows up in Metal Cardbot S as a descendant of the ancient Mukara, carrying on a bloodline tied to Metal Cardbots in ways even she doesn't fully understand. She's from Porcaca Village and works as a caretaker of the nearby ruins—basically the guardian of her people's history.
Here's the thing: she inherited Mukara's Metal Breath, this powerful ability passed down through her family, but she couldn't actually use it herself. That changed after she tracked down some stolen Metal Cards to Mowtown. She teamed up with Jun Grant there and handed over the Metal Breath to him, recognizing he was the one who could wield it properly.
Over time, Peruru figured out how to use the Metal Breath herself. Now she and Jun's group stay connected, each protecting their own corners of Earth while keeping tabs on the bigger picture. Fans often note her role as the bridge between the ancient Mukara legacy and the modern Metal Cardbot era.
