The Demon King, the very ruler of the Demonic race, the most powerful demonic being in existence. His Name.... Majin Ryujin the Demonic Dragon God. The youngest ever Demon King, and the most powerful. His Reign though only 5 years so far, has been the most peaceful for Demon Kind. That was until, the Holy Empire summoned a Hero from another world. In half a year the peace was broken, not due to Demon attack as some were lead to believe. But due to Humanity's Greed and Hubris, around three years into the war. The hero was captured, and brought to be judged by the Majin Ryujin for their crimes. Stripped naked, all their equipment taken and humiliated in front of the Demon King. The Hero looked... 

Embarrassed, yet somehow uncaring, scars riddled his feminine form some from battle, some from the abuse carried out by the Holy Empire. Crack like scars where the hero had been partly petrified and cured, burns, stab wounds, slashes, and more. Yet the Demon King didn't see the scars, he saw the underlining beauty of the hero.

Ryujin: "Hero, what is your name?"

The hero looked in shock for a moment, then began to think. It had been over three years since anyone asked his name. And he had nearly forgotten it, and it took him a moment to think of it.

Hero: "Yukino, Yukino Abarai...."

Ryujin: "I see, well Yukino Abarai..."

Yukino: "You're going to kill me right? . . . . . P-please?"

Everyone in the room was taken aback by the hero's no, by Yukino's request. It was so... looking into his eyes, Ryujin saw only... emptiness and magic power. A dead look that wasn't unfamiliar to him. He had seen a few demons with that look after the Holy Empire's forces attacked for the first time. And he realized, Yukino was probably as much a victim of the Empire as they were. Ripped from his home, treated like a tool of war. Beaten, abused, and broken into doing the Empires bidding with no choice in the matter and no way to return home. It was... 

Ryujin: "Unfair." 

Everyone looked at the Demon King in confusion including Yukino.

Ryujin: "How can I kill you, when you're as much a victim as we are? You never asked to be ripped from your home, to be beaten and turned into a tool for the Empire's war machine. If I killed you, I'd be as evil as the Empire claimed I am."

Yukino: "Th-then what are you... going to do with me?"

Ryujin: "Nothing, you can live here in the palace if you wish. We already destroyed the "holy sword" and all the other cursed equipment the Empire gave you."

Yukino: "C-cursed?"

Ryujin: "Basically it let a person puppet your body when ever they desired, even if you're exhausted or asleep."

A look of intense realization painted Yukino's face, that was why his body seemed to act on its own. He thought it was his "training" that made it like that, but he was wrong.

Ryujin: "Yukino." He placed a hand on the smaller's shoulder. "You're free now."

Yukino looked up at the taller, tears beginning to flow freely. Before Yukino feel to their knees sobbing loudly as his clutched his face. After a few hours of crying, Yukino fell asleep on Ryujin's chest. As the demon generals quietly discussed everything with the Demon King.

Ryujin: "What did you say?" His eyes flared a crimson red as he spoke.

Demon General of Medicine: "I said there is a lot of evidence of... well that the hero was... sexually abused."

Ryujin: "By whom?"

Demon General of Medicine: "By the humans your majesty..."

Ryujin: "Fuck... this... complicates things..."

The generals agreed, and they discussed things through the night. Yukino was likely more traumatized than they knew, and much more than he let on. Hopefully with time... he could be helped....

Different Forms of the Demon King Majin Ryujin:

Full Power, and unrestrained his strongest and most dangerous form. Only used in battle or in military meetings.

His Restrained form, he's smaller, has less muscles and looks a bit younger. Used during Public Appearances.

"Teen" Form. Used around the castle and its grounds, Most common form seen by his castle's staff. Used to keep his power in check and to conserve Magic Power.

Shota Form, Only used while relaxing or when his Mana is extremely low. Rarely seen, still powerful enough to destroy a large city block or so if not more. The Maids gush over him in this form and like to pamper him. He pretends to hate it, but secretly loves it as he never had parents to dote on him. And this is the closest he's able to get to having one.
