Nana Sempai is a supporting character from the anime Golden Time. She is a third-year university student and a former member of the Japanese Culture Festival Research Society, where she was a senior to Nana Hayashida, known as Linda. Nana Sempai lives in the apartment next to Banri Tada and is often seen carrying an electric guitar. She is the vocalist of a rock band and dresses in punk-style clothing, giving her a tough and intimidating appearance. Despite this exterior, she is genuinely kind and caring. Her personality is no-nonsense and blunt, but she uses that directness to offer practical and helpful advice to Banri during his moments of crisis. She acts as a mentor figure and a stabilizing presence in his life, providing a bridge between his isolated apartment existence and his social life at university. Her motivations are rooted in a desire to look out for those around her, particularly Banri and Linda, without becoming entangled in their romantic drama. She does not undergo a significant personal transformation over the course of the story; instead, she serves as a constant, reliable friend. Her key relationships include a close friendship with Linda, with whom she shares a history in the festival club, and her role as a neighbor and confidante to Banri. She also interacts with the wider friend group but remains somewhat on the periphery. Her notable abilities are limited to her musical talent as a rock vocalist and guitarist, and her emotional perceptiveness, which she uses to give sound advice. She is not involved in any supernatural or exceptional feats.
