Moriguchi Orito no Onmyoudou

A student named Moriguchi Orito arrives at a new school but becomes disoriented in the fog. He accidentally collides with a girl and experiences a sudden vision of her in a provocative stance. Mistaking his raised phone as a camera, she believes he photographed her and flees in distress, leaving behind her phone. Orito eventually locates the school, where he notices the students are unusual. His assigned seat is beside an unoccupied desk with a bag hanging from a strap identical to the one on the phone the girl abandoned.
