Fushi no Majo wa Man no Inochi wo Gisei ni Shite mo Arikitari na Negai wo Kanaetai.

After being reincarnated in another world as an immortal witch lich with the appearance of a young girl, Yuurai is arrested by royal guards on the charge of killing and manipulating the corpse of a princess. While being tortured, she casts her “Descend into Darkness” skill, consuming twenty thousand souls to gain the mighty power of a Demon Lord—and in doing so, becomes a target for extermination. Yuurai is hunted by holy knights and first-rank adventurers before eventually coming face-to-face with the kingdom’s army of ten thousand soldiers. All she wants is to live in peace, but the vicious cycle never ends. (Source: Yen Press)
