The Awakening

A long time ago, there were two goddesses called Mitsuki, the child of light, and Yami, that had grown up in darkness and sorrow because Mitsuki killed her parents. After a long fight of revenge between light and shadow, the child of light seals Yami in a human body.

Now, 400 years later, Yami is sealed in a 15 year old, ordinary high-school girl called Thalia. She doesn't know it until the goddess of shadows and darkness starts awakening in her. Lia starts hearing a weird voice in her mind and she doesn't know who it could be. Also, she really likes a guy in her class that secretly is a servant or Mitsuki.

How will it end up? Read it yourself.
