Miyako Saitou is a radiant-skinned woman with upper-back length strawberry-blonde hair that has bangs hanging on the left side and rouge-colored eyes. She is initially stated to be a young wife and thus can be assumed to be in her mid to late 30s by the time Aqua Hoshino and Ruby Hoshino start high school. After becoming more mature and kinder following Ai Hoshino's death, she is always shown wearing casual clothing to reflect her new motherly and work-driven self.
