Nanami Tenchi is a supporting character in the anime Daa! Daa! Daa! (also known as UFO Baby). She is a classmate of the main protagonists Miyu Kouzuki and Kanata Saionji, and becomes one of Miyu's closest friends. Nanami has short brown hair and is often seen alongside her other friend Aya Konishi. She is generally playful and energetic, with a lively disposition that makes her easy to get along with. However, she can become tired quickly after strenuous tasks. She has a noticeably large appetite. Nanami prefers old‑fashioned styles of clothing and is described as somewhat tomboyish; she enjoys sports and is the tallest among her friends. She is practical and sensible, and unlike many other girls at school, she is not romantically infatuated with Kanata. Her primary role in the story is as a loyal friend to Miyu, frequently going shopping with her and Aya, and providing casual support during the everyday adventures and challenges the group faces. She is occasionally aware of the unusual events surrounding the alien baby Ruu, but her involvement is mostly that of an ordinary classmate who is trusting and reliable. Nanami does not possess any supernatural abilities or special skills beyond her ordinary talents; her strengths lie in her down‑to‑earth nature, her good humor, and her dependable friendship. Over the course of the series, she remains a consistent and steady presence, showing little dramatic change but demonstrating the value of having a grounded, cheerful friend in the midst of chaotic circumstances.
