Nami Tachiba is a supporting character in the anime I's Pure. She is a classmate of the main characters Ichitaka Seto, Iori Yoshizuki, and Yasumasa Teratani. Nami is known for being the mood-maker of the friend group, often bringing energy and cheerfulness to group activities such as school trips or projects. Her personality is outgoing, energetic, and expressive. She has a tomboyish and carefree attitude that can sometimes cause awkwardness among those around her. Nami comes from a very wealthy family, a fact that becomes apparent when the group visits her large house for a project. Her motivations seem to revolve around having fun and stirring up social dynamics within the group; she occasionally tries to push people together romantically and is not shy about showing off her body, which leads some to view her as a female pervert. In the story, she serves as a supporting friend and comic relief, often lightening tense or romantic situations. Her key relationships are with her classmates, especially Ichitaka and Iori, whom she interacts with frequently. Nami does not undergo significant personal development over the course of the series; she remains a consistent, lively presence. Notable abilities are not explicitly highlighted, but her talent for making situations lively and her comfortable use of her body for shock value are recurring traits. Physically, she has long blonde hair and black eyes.
