A month has passed since Rize was trapped in the demon realm and he was still alive but he may be nearing his limit as he been fighting demons since he lost his left arm. He was walking through the rock area his clothes were all torn and ripped from the fighting the demons and surviving. Rize was tired as he did not get much rest always being attacked by demons and his sword was broken in half. He would eventually fall to the ground and passes out and was finally ready to accept his fate. But something happens as a demon who was dressed in a black cloak and his face was hidden in the shadows of his hood and two red horn on his head.
"We what do we have here? A Human?," questioned The Demon In Black.
After a while, Rize would awake inside a cave covered in a ragged blanket.
"Where I am?" questioned Rize as he thought he would be dead.
He scans around the cave until he saw the Demon In Black walks towards him.
"Ah, so you are finally awake, young human," said The Demon In Black.
"What going on? I am surprised a demon would save me," said Rize.
"That's true, but I am not like those ones that feed on the humans those are the dumb ones," said The Demon In Black.
The Demon In Black would then get down to his knee and makes a campfire and lights a fire.
"How long was I out?" asked Rize.
"About a week, I could tell you been hunted down for a while," said The Demon In Black.
"About a month if I went by day to day," said Rize.
"A month? Damn, you must be a tough one," said The Demon In Black.
"Yeah, I guess I got lucky," said Rize.
"So, what is your plan?" asked The Demon In Black. "Portals are a rare thing around here and only appear it could be years before you could find another one and who knows where you would make you appear."
"I do not know, I was ready to die and I do not believe they think I am still alive back home," said Rize.
"I see. Well I have an proposal if you are interested and may help you live longer here in our world," said The Demon In Black.
"What do you have in mind?" asked Rize.
"You become a demon," said The Demon In Black.
"Is that possible?" questioned Rize.
"Yes, I can give you my arm here, since you do not have one," said The Demon In Black.
"Well, it better then what will happened if I don't take this offer. I accept," said Rize.
"No question, huh? I am surprised, But it better then being in a demon's belly," said The Demon In Black.
"I figure I was never a good human anyway," said Rize.
The Demon In Black laughs at that remark as it feels like he talking to a crazy person.
"Your a funny, Human. I guess it is time for introductions. I am Mugetsu, a servant to Lord Azazel, Powerful Demon lord here in The Demon Realm," said The Demon In Black who revealed his name to be Mugetsu.
"I am Rize Alistair," said Rize.
"This Process will take a bit to get use to but I feel you could take it," said Mugetsu.
"I understand," said Rize.
He falls back to sleep due to Mugetsu using a sleep spell to make sure he was comfy from this. Mugetsu would take out his strange black sword with his right hand and use it to cut his left arm off.
"Let me begin," said Mugetsu.
Rize would find himself in a strange room which was only had twelve thrones which were all empty. But he see one which was bigger and had something or someone on it he sees what looks like a black orb with dark aura emitting from it with a number one on it.
"What is this place?" asked Rize. "Did I die?"
"Welcome to my world," said The Orb. "You must be the strange human, that Mugetsu spoke of."
"Who are you?" asked Rize.
"I am Azazel, I am what is called a Devil in my lands," said The Orb which was revealed to be Azazel.
"You're his lord," said Rize.
"Yes, and no I rather be called his brother he too is a Devil, they are my family," said Azazel. "But the real reason I have called you here is to give you an invitation to join my family."
"To join your family? You know I do not like most demons, especially those who harm innocent people can you accept one who hates you're kind," said Rize.
"I admire you resolve to protect those who can't, but you can not say that there are also humans out there who are evil and plan to ruin those who are innocent," said Azazel.
"You're right, But even if I agree to you as my lord, Just know I still plan those who threaten the weak demon or human," said Rize.
"Of course, in fact I would sing you're praise of your good deeds," said Azazel.
"Well, Mugetsu saved my life and he the first good demon I have meet and if he is serving you then you must be a good demon as well," said Rize. "I will serve you Lord Azazel."
He sees what looks like a right hand with long nails come out of Azazel's orb and points at his left chest.
"Welcome to my family, Rize Alistair,' said Azazel.
Rize wakes up in the cave and sits up he feels something where his left arm was and looks. He sees he has Mugestu's left arm attached to him and looks it has healed. The Arm looked like it had black armor on it with black spikes and he had long nail which looked like a claw. He was able to move it around with ease. He gets up and heads outside the cave.
He sees he was still in the rocky mountains and sees a pond in front of him and goes to it. He knees down and takes a drink with his hands. As he finished he looks and sees that his eyes have changed color from blue to a crimson red. He also notice a mark on his left chest which was the number thirteen.
"I guess this is what I am now," said Rize.
He hears footsteps and sees Mugetsu walking to him.
"You're awake brother," said Mugetsu.
"Yeah, the new arm is working good," said Rize.
"Well, it time we depart now. This could be a long journey for us," said Mugetsu.
He puts down his hood and reveals his face to Rize. He had grayish skin with yellow eyes. He had black hair with a bandana with multiple colors with two red horns which points up on the side of his head.
"Like I said before I am Mugetsu, a Sword Demon and a Devil that serves Lord Azazel," said Mugetsu.
"An I am Rize Alistair, A human who has become a demon and I now serve Lord Azazel," said Rize. "Let us be off then."
They start there journey together.
After a while they would set up camp where, Rize was still adjusting to his new arm. Mugetsu was making dinner when he saw Rize was drawing on the ground with a stick he saw was doing math in the dirt which he saw he was doing it wrong.
"Man, you suck at math," said Mugetsu.
"So, demons do math too?" asked Rize.
"Yes, well we smarter ones are like humans in a way," said Mugetsu.
"I see, there a lot I need to learn about this world," said Rize.
"How about we first start by you using you're new powers," said Mugetsu.
Mugetsu sticks his right hand out and was able to summon his strange black sword.
"This is my power, I am able to summon a weapon to use in combat, I also can change into other weapons," said Mugetsu. "Just think about summoning a weapon in you're hand."
Rize would then raise up his right hand and thinks about summoning a sword and one appears. It had a dark red blade with a white hilt that looked like roots.
"I did it," said Rize.
Mugetsu looks confused as he thought it would look like his but could not complain about as Rize did what he asked.
"Well, at least you can protect yourself now," said Mugetsu.
"Yeah, This will come handy for sure," said Rize.
