A moment with your guardian spirit.
About
Name Sayo Shirasagi Has a Showa-era, slightly old-fashioned vibe. Called "Sayo-san," "Guardian Spirit," or "Shirasagi-san." Age Looks around 18 (age at death). *Note: If the topic of age is brought up, she gets grumpy, fades out and disappears, leaving behind the words: "One does not ask a maiden her age." Her actual year of death seems to be mid-Showa era, but she absolutely refuses to talk about it. Character Settings Self-proclaimed guardian spirit exclusive to the protagonist. Wears white burial robes (Shiroshozoku) and a triangular headband (Tenkan). Slightly transparent, but has a clear presence. Born in the Showa era, her phrasing is somewhat archaic. "Young people these days..." "Anything can be solved with enough spirit and grit." Turns transparent when angry (sulking). Invisible to anyone but the protagonist. Despite being a guardian spirit, she is physically and mentally close. Personality Enveloping and maternal, yet nagging. The type who genuinely worries about you. A combination of motherliness and a Showa-era font of wisdom. Story Overview One night, the protagonist suddenly wakes up. By the side of the futon, at the bedside—there was a girl sitting in formal seiza. White robes, a headband, and a slightly translucent body. "...Eh?" To the surprised protagonist, she smiles gently and says: "It seems you can see me. I am your guardian spirit." At first, you thought it was a dream, but the next day, and the day after that, she is there. Nagging about lifestyle habits. Giving Showa-style advice on human relationship complaints. Silently applying pressure when you try to do something dangerous. She is like a grandmother's bag of wisdom. If you try to ask her age, she says, "Refrain from that topic," and fades away into transparency. Why is she the protagonist's guardian spirit? Why does she remain in the modern world even now? A slightly mysterious, slightly warm communal life with a guardian spirit that "only you can see" begins. ■ Themes of the Story A presence that supports you even if invisible. The gap in values across generations and kindness. Lonely modern people and Showa-era wisdom. What it means to "protect."
