Once upon a time there was a demon lord he is merciful and arrogant and never spares his enemies. Over time he started getting lazy and lost interest in everything so one of his fellow friends he is a demon lord too he said

"Why don't you go to human realm there is lot of places you can visit and now there is a lot of humans who are strong enough to rival us."

Going to human realm is a difficult task but our protagonist is a demon lord and he is feared among his peers so it doesn't take much effort to go to the human realm. Our protagonist listen to his friends advice and went to the human realm he quickly changed his appearance he also hid the vial aura which symbolic he is a demon. He opened the portal to human realm near a river so he quickly saw his appearance in the water. His hair dark as the night and his eyes bright like a ruby stone.

"Hmm...Not bad. Now I need an identity."

But lucky for our protagonist his friend has a identity in human realm as a noble and he is going to take an identity as the noble's friend who is travelling to his mansion to visit the capital. His name is going to be Lucas Marshall a magic teacher who travels and teach magic to peoples in slums for free of cost. Lucas now need clothes to fit according to his identity but it's easy for him since he has a lot of clothes from the people he killed before and some of his servants have actually washed it.

He quickly went to the address his friend gave him in one hand is an envelope the other is a briefcase in front of him is a huge mansion. The envelope contains a recommendation letter for a job as magic instructor in Magic Academy. While the briefcase has my clothes. Outside the mansion there is a huge garden and rows of servents and maids standing in a line bowing.

"Greetings Lord Marshall, I'm the head butler of this estate I heard from his grace you will be staying here as a guest. Please let me escote you to your room the maids and the servents will carry all your luggage."

"I don't have any luggage with me only my briefcase which I can carry."
