Nora is a stray dog who joins Bun Bun, an abandoned puppy, and another dog named Bunta. She becomes a steadfast companion to Bun Bun on his quest to find his mother, forming a core group navigating challenges together. Their journey is fraught with danger due to pursuit by a cruel dog breeder determined to capture Bun Bun for dogfighting. Nora aids the group in evading this antagonist and surviving a world hostile to strays. She appears throughout the television series' 39 episodes as a consistent member of Bun Bun's core group. While a separate movie exists for the franchise, it follows a different storyline without Nora; Bun Bun searches elsewhere with different companions in that film.
