Tensei Akujo no Kuro Rekishi (The Reincarnated Villainess’ Dark History) follows Konoha Hoshikawa, a high school girl who dies unexpectedly and is reborn as her own original character from a fantasy novel she wrote years ago—a cruel and powerful villainess named Diarte. To her horror, Konoha realizes that the world she created is far darker and more dangerous than she ever imagined, filled with betrayals, bloodshed, and the consequences of her own teenage writing. Determined to survive and avoid the tragic fate she once penned for her alter ego, she must navigate deadly politics and tangled romances while concealing her true, timid nature behind the mask of the fearsome “Dark Witch” Diarte.
