Deo

"I am the light called upon from the heavens...to destroy the Earth."

- Deo Deo (デオ, Deo) is a Demon and one of the Thirteen Calamities, sealed within Bellum, the country of warfare. After being freed, the broken seal destroys its original body, forcing it to retire to a form of pure white light. It ended up travelling at incredible speed, until it eventually struck a girl in Fiore, possessing her body, claiming it as its own. Deo now tries to recover its lost form, whilst trying to blend in, taking up the alias of Kokoro Hakuma (心白魔 (ッッコロ ハカマ), White Demon Heart), a normal schoolgirl who an introvert and anti-social.
