Majo no Kaigashuu

Aisya, a young girl living in an orphanage, possesses a mysterious power: when she paints with her own blood, the resulting paintings cause miracles. Yet the works born of her goodwill become tainted by human greed, and in time they begin to harm people. They have come to be known as “The Witch’s Cursed Paintings.” Aisya entrusts her final wish to her dearest friend—Loki, whom she herself had painted—and asks him to burn all of her creations. Bearing that heavy promise upon his shoulders, Loki sets out on a far-reaching journey!
