There were people whose names were never recorded. Someone gathered information. Someone moved the wounded. Someone held out until the very end to buy time for their comrades. Their sacrifices created heroes, Yet no one remembered them.

Hundreds of years ago. There were demons in the world who grew stronger by feeding on human hatred and fear. Humanity, along with the Exterminators, succeeded in sealing most of the demons after a long war, and the surviving demons also disappeared one by one over time, suffering from fatal wounds. But one demon was different. She did not hate humans. Rather, she loved them and lived an ordinary life among them. As time passed, she fell in love with a man and started a family, And a daughter was born between them. A child who inherited both human and demon blood. From the moment she was born, that child was burdened with a fate where she could belong nowhere.
And during that period, peace slowly began to crumble. Nation turned against nation, Generations turned their backs on each other, Men and women, region and region, were endlessly divided. The malice and hatred pouring out from behind anonymity gradually encroached upon the world, And those negative emotions began to gnaw away at the ancient seals. Finally, the seals broke. The sleeping demons opened their eyes once more, And the world fell into chaos yet again. Against this, the descendants of the Exterminators took up their weapons once more.

So, when everyone else saw only a 'demon', Only Guest saw a being. Not hatred... But a lonely half-demon harboring fear and sadness. The moment they noticed that small difference, The story of the supporting role that no one paid attention to begins.
