Black Zodiac: Demons and Deceptions

Celestia, the world of Celestials, was destroyed and put into great chaos when some celestial mages lusted for great power and summoned demons into their world to acquire magic that can rival a god. However, it turned the other way around. Demons wrecked havoc on their world and made Celestia as a new demon realm.

Lumia, the goddess of sky, bestowed her 12 graces of zodiacs to 12 children that will soon restore their land from those filthy creatures. One of these children was Princess Cerina, who has the grace of the Cancer. She is the daughter of an empress with a divine blessing from her deceased parents. At a young age, she was one of the Magic Ministry's strongest mages who pioneered the founding of Caelum Academy.

When she was only 10 years old, an unprecedented event happened as she was possessed by a higher-ranking demon. As a result, Arianna, the mage who adopted her, sacrificed herself just to seal the demon inside her, including her magic. Eventually, Cerina lost her memories and was left in front of a monastery on Earth.

11 years later, an unknown shadow creature attacked her in the middle of the night but luckily, she was saved by one of her co-Celestial Twelve named Raid. Afterwards, many things happened as her memories gradually came back.

In order to save her friends, she decided to formed a blood pact with the demon within her. And her grace became a half-curse. And it was called by her demon, Black Zodiac.
