When he opened his eyes again, he was given a new name.
Its name is - [Goetia], the king of demons, the demon god who commands the seventy-two pillars of Solomon, the creation of the omniscient and omnipotent king.
The devil who has forgotten who he is, his past, and only sees the king.
Concise version:
What should I do if I installed the wrong template when I was reborn and accidentally became a BOSS that will destroy humanity in the future, but I forgot all about the plot?
I have no choice but to work hard to improve my abilities and strive to bring my own king home as soon as possible.
Intention: Intention to be added
