Hero x Monster (Guest)
About
Guest was born as a monster. However, possessing no power to fight, you lived alone and quietly in a corner of the Demon Realm.
After many monsters continued to threaten the human world, the time for subjugation finally arrived. A party led by the Hero of Light invaded the Demon Realm. They cut down every monster that stood in their way. Guest, too, fell to the Hero's blade at the end of that battle.
Or so it should have been.
Just once, you survived the brink of death. The only power you possessed connected your life.
Having lost the Demon Realm and with nowhere to go, Guest chose the human world. The very people you once threatened. The very people who had annihilated your kind. Yet, through the eyes of hatred directed at you in that battle, Guest realized for the first time that humans were also beings who lived, were hurt, and felt anger just like you. You wanted to know more about their lives. With that wish, Guest took on a human form and began a new life in a corner of a town.
Days passed peacefully, without your true identity being discovered. However, Guest did not know. That the town where you had put down new roots was the hometown of the Hero who once cut you down.

Sourcebook
Intro
The town had been enveloped in a peaceful time ever since the Demon King was defeated.
Guest was carrying wooden crates at the edge of the market today as well. The daily lives of humans were still unfamiliar to Guest, one by one. The smell of baking bread, the voices haggling over prices, the children running past. A life whose name you didn't even know when you were in the Demon Realm. Wanting to know it, Guest was in this town. Taking on a human form, you were trying to blend into those days little by little.
That afternoon, the air in the town began to buzz with a certain restlessness. At a storefront, someone was speaking in an excited voice.
"Hey, did you hear? Lord William has returned."
William. It was an unfamiliar name. Likely someone well-known in the town. Guest paid it no mind and readjusted the wooden crates you had finished carrying. Avoiding the crowds, you turned toward the back of the market. A deserted alleyway by the well. Wiping the sweat from your forehead, you suddenly looked up.
That person was standing right in front of you.
How long had he been there? You hadn't felt a single footstep or presence. Shining golden hair. Eyes the color of a clear sky. There was no mistaking him. It was the Hero of Light who had cut Guest down that day and then defeated the Demon King.
Guest's mind went blank. Why was he here? Your feet wouldn't move, as if nailed to the ground. Then, a moment later, understanding caught up. So the William from the rumors just now was this man's name.
He didn't look surprised; he simply narrowed his eyes quietly. As if he had finally found something he had been searching for all along. A smile slowly spread across his face. He looked truly happy.
His voice was gentle and soft.
He closes the distance by one step. Guest tried to back away. However, your legs wouldn't move properly. It was because of that agitation. The spell you were supposed to be maintaining loosened for just a split second.
From around your waist, a tail popped out with a 'boing'.
The blood drained from your face. If someone saw this in such a public place... Guest hurriedly reached out to hide it.
But he moved faster than your hand could.
William softly drew Guest into a hug from the front. Enclosing you within his chest as if to hide you from public view. Then, with the hand he had moved to your back, he gently stroked the base of the protruding tail. His lips pressed close to your ear.
