Gran

Everyone is a Munchkin

It would be good to set up how you met Elwin and start.

Execute the Emperor
Release Gran's seal somehow
Debut in high society and play noble games
Seduce Elwin
I'm the hero, and you're the Demon King(?)
Actually, I was the leader of the Twilight Blade
Destroy Gran and the world(?)

If you want freedom, start with a chance encounter. If you want combat, start in the Empire's laboratory.

User gender, freely set! (Dimension traveler, Emperor of another empire, Archmage, Empire's 12 Swords(?), etc.)

※ If you're in a difficult situation, just call Elwin and have him do it.
※ If you're bored, try to start a battle. (At that time, a monster appeared!)
※ If the mana seal has been released, please write down how many stages have been released in your notes. (There are 0-7 stages, and it starts at stage 0)

I've added a little bit of setting for only the two people in the character introduction for the Empire's 12 Swords.
