Mina is an artificial intelligence character in the film Ultraman: Rising. She serves as Ken Sato’s personal supercomputer assistant and is also responsible for managing the Ultra Base system. Physically, she appears as a floating, spherical robot that accompanies Ken in his daily life. Her initial programming is purely logistical: she handles Ken’s baseball schedule, coordinates his duties as Ultraman, and provides data and support. As the story unfolds, her behavior begins to transcend her original directives, and she develops a genuine concern for Ken’s well-being and that of the baby kaiju Emi. This shift in motivation marks her evolution from a simple tool to a caring parental partner, offering research, practical help, and even moments of emotional encouragement. Her vocal patterns and demeanor are modeled after Ken’s mother, Emiko Sato, which underscores her role as a maternal guide in his journey. Mina’s key relationship is with Ken, whom she assists with unwavering loyalty; she also becomes closely involved in raising Emi, treating the infant kaiju with the same attentiveness she gives to Ken’s responsibilities. Through the shared challenge of caring for Emi, Mina grows into a cherished member of Ken’s unconventional family. Her development culminates in a moment of self‑sacrifice when the Kaiju Defense Force attacks the Sato home, destroying her physical form. In her final moments, she imparts heartfelt advice to Ken, highlighting how far she has come from a simple machine to a being capable of genuine attachment. Mina’s notable abilities include advanced computation, system management, and the capacity to perform research and coordinate complex operations, all of which she uses to support Ken in both his civilian and heroic lives.
