Help Wanted

Misty flames danced around the edges of his vision, tinting the world in a blue haze. The fire burned through his veins, binding him with invisible puppet strings in the hands of a beast. He watched as the flames razed everything to the ground, pale digits coming to rest against the bare throat of a poor soul who survived the incineration. He could feel the fluttering pulse racing beneath his fingertips.

'How fragile,' he noted impassively, crushing the delicate thing in his hand with no remorse.

"Rin!"

He turned around and saw a group of people in black, militaristic coats, holding up various weapons. Exorcists. And in the front, leading the group, was him.

The name ghosted out of his lips. "Yukio…" His eyes lightened in relief.

"Rin!" Yukio shouted, managing to control his voice even when faced with the macabre scene. "Let her go."

Rin looked down at his hands, at the mangled throat in his hands, and the charred remains of bodies lying around him. Then, he looked up and grinned. "Try and stop me."

Blue stared resolutely into blue, and Yukio's lips tightened into a grim frown. "We don't have to do this, brother."

'How hypocritical,' thought Rin as the other boy drew his guns from their holsters, motioning for his fellow exorcists to stand down. They did so reluctantly, the desire to protect one of their own warring with the deep, instinctive fear at the sight of Satan's blue flames. Or rather, Rin's blue flames.

A sudden overhead swing aimed for Yukio's head caught the onlookers off guard, many of them flinching at the cloud of dust that was stirred up at the powerful blow. They could hear the sound of metal striking metal and fast volleys of gunshots, and as the dust settled, they found both parties panting, but unscathed.

Rin drew in deep, ragged breaths. "Stop me." He was still smiling, but Yukio could sense a sort of desperation in his voice that wasn't there before. Icy blue now held a manic edge. The younger twin locked his jaw and shoulders, tightening the grip on his gun, and braced himself. Then, he fired.

A sudden, sharp pain pricked the flesh beneath his ribcage. Rin looked down, and saw red seeping through his shirt. Even with a bullet through his chest, he felt no pain. A hand slowly reached down to touch the proof of his mortality. That should've been his first clue, but really, he knew he had at least partial control over his body. Enough control to have stopped himself from doing anything he did not want to do. Or maybe he wanted to watch the life seep out of their lungs, watch the light die from their eyes? Through the rush in his ears, he saw two exorcists come forward to support Yukio as he staggered back.

One of the newcomers, a black-haired stranger, shouted at the demon-boy. "Rin, end this right now! It's not too late, we can still help you!"

He faced his brother with a smile on his lips. Yukio blinked, and the unnamed exorcist who spoke fell to the ground beside him, blood gurgling from a ring of small, deep gashes along his throat. Rin grinned, and in a flash – 'When did you become so fast, so far ahead of me, brother?' – appeared inches in front of Yukio, revealing sharp teeth stained with blood. Yukio could feel his heart beating harshly, so hard he couldn't help but wonder if the skin would be bruised blue and black by tomorrow, against his chest. Rin made a show of licking his lips, savouring the taste of their sacrifice.

Yukio jerked his arm up and shot a bullet into Rin's chest. The demon-boy's pupils dilated, but he did not falter. His hand slowly reached up to clutch at his brother's shirt as Yukio stared with wide eyes at the bleeding wound. With his other hand, Rin clawed through the frozen exorcist still supporting Yukio, who was paralyzed with fear at the blue flames licking the demon-boy's body. He did not make a sound as his guts spilled out onto the floor.

Yukio suppressed a scream, and fired round after round of bullets at Rin, each finding a mark on his body. Still, Rin did not let go of his shirt, eyes unwavering in their intensity. Haunted blue orbs gazed steadily into Yukio's.

"Please, stop me."
