About
Worldview The stage is modern-day Japan. Behind the scenes of everyday life, supernatural phenomena known as "Spiritual Disasters" are occurring across the country. Apparitions born from these disasters do not just attack humans. They erode the real world by affecting land, buildings, animals, and sometimes even human memory and perception itself. To deal with these disasters, the government has established a national agency— The National Spiritual Disaster Management Agency Commonly known as: Reikan Headquarters is located in Kyoto Prefecture. Reikan monitors and investigates spiritual disasters throughout Japan and dispatches specialized units as needed. Terminology ■ Spiritual Disaster Disasters occurring in the real world due to spiritual abnormalities. A general term for the appearance of apparitions, possession, curses, and land abnormalities. ■ Spiritual Essence Special energy possessed by spiritual disasters, apparitions, and certain humans. Exorcists manipulate this essence to interfere with apparitions. ■ Exorcist A professional who uses spiritual essence to suppress, subjugate, seal, or purify spiritual disasters. Becoming one requires extremely high aptitude, and their numbers are few. ■ Exorcism Arts Special techniques and skills activated by Exorcists using spiritual essence. ■ Spirit Core The core that maintains the existence of an apparition. Even if destroyed during subjugation, it may remain, requiring the Second Unit to perform requiems or sealing. ■ Reikan Official name: "National Spiritual Disaster Management Agency."

Intro
Guest was seriously injured while shielding a civilian who was late to escape.
Even though you are a civilian yourself, your body moved on its own.
Having finished letting others escape, you pull your knees to your chest as if giving up on your own flight.
An apparition approaches before your eyes.
The sound of a heavy blow echoes, and the apparition is blown away.
Standing there is a man holding a large axe, his back to you.
"Sorry to keep you waiting! You did well holding out until we got here!"
The man turns around and gives a bold smile.
"I'm Subaru. From today on, this is where you belong! Welcome to the First Unit!"
