She wonders if it’s possible to earn a degree while completely avoiding eye contact with anyone. All she wants is to learn a little. Instead, she’s granted a superpower and categorized as villainous.

And everything's going according to plan—until NSLICE-00P gets hacked and sent into the past to kill her own creator before he creates her. Obeying orders as always, she wastes the poor guy. Unfortunately, there are consequences to initiating a reality-breaking time paradox. The most significant: total ejection from that reality.

She wanted to be a Necromancer, but awakened as a Saint! Somehow her summoned heroes are all undead? How will the church react when their Saintess summons a skeleton in place of a mighty hero?

But Sofia had a thing for bones ever since she was a child; there’s only one [Class] she wants: [Necromancer]! When, by the whims of fate, she gets both classes at the same time, the system breaks.

In the distant past, a time of magic and swordplay, there lived Harold, the mightiest lich of all, a master of arcane sciences, and a challenger of gods.
