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, becoming a target for extermination. Yuurai is targeted 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.
