Comet Lucifer

On the planet Gift, deep underground veins hold a coveted crystal resource known as Giftium. Sougo Amagi, inspired by his late mother’s work as a researcher, spends his days in the mining town of Garden Indigo searching for the rare specimens found only in the area.

A school dispute sends Sougo tumbling into the abandoned mine’s depths, where he encounters something far more extraordinary than any gemstone: Felia, a mysterious red-eyed, blue-haired girl who appears from within a massive crystal. As Sougo and Felia grow close, a covert organization closes in, intent on exploiting her abilities—forcing Sougo and his friends to protect her while uncovering who she really is.
