A Kingdom of Quartz 4

In a world where angels protect the people against demons, a young orphan with pitch-black wings may hold the key to the kingdom's fate. An exquisitely drawn, dark fantasy manga for fans of Puella Magi Madoka Magica, Made in Abyss, and Witch Hat Atelier.

After narrowly avoiding execution by the Seraphim, Blue learned the horrible truth about Noah’s treatment at the hands of the Church. A short-lived adventure with Killian also brought Blue face-to-face with the mysterious Oracle, who urged her to embrace the darkness within her.

Blue then joined Steele and her Angels on an emergency expedition to find Adira’s team. Yet crossing the kingdom’s gates, they stumbled upon a grisly scene of fallen Angels and a pulsing egg, which soon began spewing forth Demons. As one giant Demon looms up over the rest, Steele points to something in its chest. Could that be...Adira?
