Shadow, 大友 陣

Harutora's homeroom teacher is known for being somewhat eccentric, with a relaxed demeanor that might surprise some people given his role as an educator. However, despite this laid-back approach, he has been praised for providing valuable guidance to students and advocating against strict school policies related to education. Despite losing his leg in battle with Ashiya Douman, Harutora remains a formidable figure who is well-respected for his past as a Magic Investigator and Divine General, where he was nicknamed "The Shadow" due to his stealthy nature. After resigning from his position as an investigator, he took on the role of homeroom teacher at Onmyo Preparatory School in order to monitor and safeguard Natsume, a student with unique abilities related to spirits.
