Comet Lucifer

The town of Garden Indigo is home to Sougo Amagi, a young boy who inherited his interest in Giftium, a highly sought-after crystalline substance, from his mother, a researcher. Sougo lives in a small but prosperous miner's community where he has opportunities to collect rare crystals, but his life takes an unexpected turn when he discovers Felia, an enigmatic girl with red eyes and blue hair, emerging from a large crystal in an old mine. Felia is being pursued by a secret organization and Sougo and his friends must help her evade capture and uncover the truth about her powers and origins.
