Hitomi Aasu, the three-year-old youngest of seven sisters guarding Earth, yearns to hasten her maturation, fixating on acquiring adult physical traits. Her Earth Precognition ability grants visions of looming threats, though these manifest unpredictably—mid-sleep, during baths, or enemy confrontations. While accurate, her prophecies occasionally align with bodily functions or forecast obvious events, causing urgent danger alerts to be misread as bathroom emergencies. Outside these episodes, she radiates playful exuberance, her worldview colored by an upbringing among six eccentric elder siblings. Her name, drawn from the Japanese word for "one" (hito), ironically marks her as the seventh-born, following the family’s numerical naming tradition. The Aasu sisters wield strictly protective magic, relying on external allies for offense. As their primary early-warning system, Hitomi’s sporadic visions are treated with gravity, despite their chaotic timing. This juxtaposition of her childish impulsivity and vital guardian role weaves levity into high-stakes defense operations, blending urgency with inadvertent comedy.
