This necromancer is going to seduce the beautiful girls who are already dead.

The descendants of time travelers—five genius girls—possess divine power. Winning over them would allow one to surpass humanity! However, they seem to have been dead for decades, making them impossible to win over?
"It's just a dead person. Just dig up the grave, pull them out of the coffin, and that's it. Sorry, but we necromancers really can do whatever we want." — Necromancer Abyss
