Nené Sakurada is a five-year-old girl and a member of the Kasukabe Defense Force, the close-knit group of friends from Shinnosuke Nohara’s kindergarten class. She typically presents herself as sweet and proper, but beneath that surface lies a strong-willed, sometimes bossy personality that she has inherited from her mother. She enjoys orchestrating elaborate pretend games of “real house,” which often involve dramatic arguments or divorces, and when frustrated she vents her anger by hitting a stuffed bunny. In the film, Nené is drawn into an adventure when a time-traveling woman claiming to be Shinnosuke’s future bride appears. Along with the rest of the Defense Force, Nené travels to a dystopian future to rescue the adult Shinnosuke. Her motivations are rooted in her loyalty to her friends and her natural curiosity, though she also displays a practical, occasionally manipulative streak. In the future timeline, Nené encounters her adult self, who has become a kindergarten teacher. This encounter highlights her personal development: the adult Nené retains the same core personality traits but has channeled her energy into a nurturing profession, showing a more responsible and caring side. Throughout the story, Nené contributes her quick thinking and assertiveness to the group’s efforts. Her key relationships include her fellow Defense Force members—Shinnosuke, Kazama, Masao, and Bo—with whom she shares a bond of friendship that persists across time. She also interacts with her future self, providing a mirror for her own potential growth. Notable abilities include her talent for manipulation and persuasion, often used to steer games or get her way, as well as her capacity to adapt to strange situations without losing her composure. The film does not give her any supernatural powers; her strength lies in her personality and her role within the group dynamic.
