Once the academy's youngest instructor, Claude vanished under mysterious circumstances, leaving behind a legacy that inspires Spica to pursue her dreams.

However, Spica struggles to gain traction in her magical training due to her lack of experience and connections. Her fortunes begin to change when she encounters a talking black cat endowed with magical powers. Eager to learn and improve her skills, Spica pleads with the cat to become her mentor, but he agrees only if she can find a way to lift his feline curse.
