The world of Morphos Metaphor is set in the city of Kirimori, where supernatural events challenge the peace of its residents. Locals stir the rumored sightings of ghosts and shadows at sunset, the police receive monthly reports of missing people, and comatose has become a prevalent case among the patients rushed in most of the city's hospitals.

You are a student in Kirimori City's prestigious institution, Higashimori High School. The school prides itself with its high quality of education, living up to the school's firm belief that the best education can be attained, but only to those who have the potential to succeed.

Kirimori is a place where mystery and illusions embraces the city at night, although, there are no secrets which forever remain hidden, for the Arcana is the means by which all is revealed.
