Gokumon Nadeshiko Koko ni Ari

A powerful family with a dark heritage resides in a hidden fortress in Kyoto, feared by both magical beings and supernatural creatures. Nadeshiko, a member of this lineage, is known for her beauty and monstrous nature, feeding on creatures of the night. Her perspective shifts when she meets Amana, a striking and fearless woman who challenges her. Strange occurrences follow, including a hidden chamber filled with flowers, a sacrificial figure in a box, a curse affecting the school, and encounters with deceptive and formless entities. As they face these supernatural threats, they confront a deeper truth about themselves. Nadeshiko, who was once a monster in human form, and Amana, who is human in a monstrous body, form a bond that will be bound in blood.
