Aka no Grimoire

For most, inheriting a dilapidated mansion would be little more than a bureaucratic burden, but for Oomugi Wakaba, it is the key to an astonishing descent into the arcane. The estate, left to her by her late great-grandmother—a reclusive virtuoso of pen art—is a labyrinth of dusty corridors and walls adorned with hauntingly lifelike ink sketches. While exploring the depths of this eerie property, Wakaba stumbles upon a secret chamber hidden behind the wooden paneling, a place that defies all logic of the mundane world. There, she is confronted by a vision of chilling beauty: a young girl with piercing blue eyes, her slender frame bound by writhing, crimson chains that pulse with an otherworldly light. The girl identifies herself as Red Riding Hood, but she is far from the innocent figure of fairy tales. Wakaba quickly realizes that the chains are not merely restraints but a seal, and Red Riding Hood is not alone. By her side resides the "strongest beast," a formidable creature of immense power that serves as both warden and weapon. As the crimson bindings begin to loosen and the girl stirs, Wakaba is forcibly drawn from her ordinary existence into a breathtaking and treacherous world she never knew existed. This is the realm of magic, where witches weave ancient and perilous spells, and grimoires contain forbidden knowledge capable of reshaping reality. With the enigmatic Red Riding Hood and the fearsome beast as her unlikely guides, Wakaba must learn to navigate this dangerous landscape, uncovering the true purpose of her great-grandmother's legacy and the reason she was chosen to inherit this secret—a truth that will test not only her courage, but the very fabric of her sanity.
