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.

Blue finally achieved her dream of entering Helios Training Academy and even managed to win some people over with her bright smile and indomitable spirit. Just when things were looking up, a mishap during a magic class triggered Blue’s dark power and left Tannith cursed.

Blue is then seized by the Seraphim, the Church’s pitiless adjudicators, and taken before the king to answer for her crime. The king seems all too willing to put her to death, but Cassian and Killian step forward to plead for her life. Can Blue undo the curse on Tannith and prove her innocence...or is it too little, too late?
