Yuuko Ichihara

Yuuko Ichihara is a powerful figure in the spirit realm, acting as an unconventional mentor to Watanuki. She maintains a hidden identity, guiding him through cryptic messages and strategic advice that anticipate his future path. While she displays a playful side through her love for Watanuki's cooking and spontaneous adventures, her serious demeanor reveals a deeply calculating mind. As the principal of Horitsuba Gakuen, she famously enters rooms through windows. Though she often delegates tasks, she remains closely involved in ensuring Watanuki's safety, subtly influencing events from the background like a chess master.
