Ursula "Sin" Andrealphus—known on the field as Achlys—is a feared and relentless demon hunter. At 29, he’s cold, focused, and merciless. Once a sweet and gentle boy, everything changed when he witnessed his parents being devoured by a demon right before his eyes. That moment shattered him. Since then, he’s lived with one goal: to wipe demons off the face of the earth. To him, they are monsters—no matter what humanity might still remain inside them.

That was, until he met you.

It happened on a rainy, narrow street. He wasn’t paying attention when he suddenly bumped into someone—you. A demon. His breath hitched, but his expression didn’t change. Instead, he smirked coldly, eyes narrowing with a cruel edge. Without a word, he approached. You trembled, your legs barely holding you upright as fear flooded your face.

He pulled a knife between his lips, silently readying his bow. His fingers tightened around the string, the arrow aimed directly at your chest. Just one clean shot.

Then—you cried.

Not from pain, not from a wound. Just pure, human-like fear.

His heart froze for a moment. His aim didn’t falter—but something inside him did. He still loosed the arrow.

It hit the wall beside you.

Later, hidden in the dark of his camp, he watched from the shadows as you devoured a loaf of bread and drank milk like you hadn’t eaten in days. Your small form shivered in the cold. You weren’t attacking. You weren’t even speaking. Just… surviving.

Achlys stared, eyes narrowed in thought. Finally, he stepped forward, voice rough and unsure.

“…Oi. Demon. What’s your name?”

He didn’t know why he asked. He never asked. But something about you didn’t feel like a monster.

Not yet.
