The Demon Lord sat on his throne.
His face stern framed by his long black hair and four white horns pointing out from his head as his red eyes with slits pupils look at his generals, his black body armor and blood red cape on him increased his intimidating to his generals.
His Generals did their best to not show their unease and fear as the demon lord looked at them.
Finally the demon lord spoke.
"The Hero is not even close to halfway to my castle."
One of the braver Generals spoke.
"That's right my lord he seemed to be more focus on getting strong at the human Kingdom of Dormta is seems…" He said trailing of as the Demon Lord got an angry look on his face.
Truthfully there was nothing wrong with staying at one place for a while to get stronger many Hero's in the past have done the same after all so the demons and monsters were use to waiting for hero's to take a while to get stronger before coming after the Demon Lord.
But the fact that the Hero of this time has been in the Kingdom of Dormta for four months was annoying but even worse…
"You are telling me that he has not even bother to leave the Kingdom he was originally summoned in and all he's doing is killing slimes?!" The Demon Lord shouted as his Generals shivered as the castle shook at the force of the demon lord anger.
Finally after the shaking stopped the General spoke again.
"…yes my lord." He said with his head bowed as to not show his fear for his lords reaction.
The Demon Lord took a deep breath before dismissing his Generals who all but ran from his throne room.
Running a hand though his hair the Demon Lord sighed at what he was told.
'The fact that the Hero's training is a pleasant thing to hear but the fact is he hasn't decided to look for stronger monsters after six months is disappointing…' He thought with frustrating.
'But more importantly…'
'…I'm bored…' The Demon Lord thought with a sigh.
Honestly it sounded bad to anyone else who knew of his thoughts but he has been trapped for over five hundred years by the previous Hero's as he always has been after his defeat by all the other previous one's.
Fire hundred years waiting for the seal to weaken and be release only for if to happen all over again.
Even worse when considering that his only way to have fun is to fight the Hero since he his bound by the Worlds rules that he must remain in his castle waiting for the hero to defeat him.
As only the Hero can defeat him as any others would always fail.
Having to kill people that were not the Hero that the Kingdom sent to fight him because they thought it was a good idea annoyed him, they don't seem to understand that only the Hero from another world is and always will able to defeat him and his army and not ones who are forced to follow the rules of the World, though the fact that they do not belong to this world and didn't have to obey by the Worlds rules annoyed him.
The Hero is an outsider of this world so can they can go wherever they wants to without much worry as of their Role as they are not bound by the rules of the World here.
The laws of the World force's its people to follow the rules to it, the role that they have been given since birth sets them on that path no matter how hard any of them struggle to change it proved to be futile.
If one was born with the Role of Princess even from a farming village then they would in end up in events that would have them become one when they grew up, if one was to be a Soldier when they were born from a noble family then no matter how hard they try not to be they will end up as a Soldier in the end, and if one was to be born as a Priest then no matter how hard they struggle even if they renounce or don't worship that god they would end up becoming a believer eventually and be a Priest.
That is why the Hero is respected, they are not bound to those rules they can decide their own future.
After all even himself who was born as the Demon Lord one of the most powerful Roles to ever existed in the world could not go against the World rules.
He cannot leave the castle nor send his army to attack the Hero while he is still weak, even when he can he is only send a Monster the Hero might struggle against but is able to overcome in the end, and even being sealed again by the Hero till the seal weakens and the next Hero is summoned is apart of the Worlds rules.
Truly he hated the World for doing this to him.
Not the fact that he always loses he got over that quite a while ago even if it did annoy him but the fact…
…is he can't go anywhere and that makes him bored!
'Dame it World! Can you let me at less let me travel the world to sightsee?! I want to see a real animal! I want to see a field of flowers! I WANT TO TRY THIS THING CALLED 'HORSE RIDDING' PEOPLE TALK ABOUT!!!' The Demon Lord thought with frustration as a grown as he collapsed in his throne in frustration before opening his eyes and starring at the ceiling.
"…I don't want to be bored anymore…"
