"So what will it be, Brother?" The demon smirked.

Rin ground his teeth in frustration.

"Don't Rin!" Yukio protested. "It's exactly what they want-"

"You don't think I know that?" Rin shouted, breaking his train of thought. Rin Okumura had always anticipated that something like this would happen, but whenever he thought of how he would get out of the situation, his mind would wander and he's lose interest quickly. However, whenever he did try to come up with a plan, Mephisto had always been a major player-who, at the moment, was absent.

'I'm going to kill that bastard,' Rin thought angrily.

"Made up your mind yet?" The demon snickered, and Rin saw its grip tighten on Yukio's throat.

When Rin saw the light fading from his brothers eyes, he put his sword back in its sheath and he felt the flames that marked him as Satan's son reside back within himself. Rin didn't look up, but he heard his brother fall to the ground and start gasping for air. As long his brother was alright Rin could sacrifice himself.

"Now was that so hard?" The demon asked, his voice slick and smooth.

Yukio looked up, wide eyed and shaking his head. "Rin, what do you think you're doing? What about me? Or the guys? What about Shiemi?"

Rin stopped in his tracks, but refused to look his brother in the eye. He took a moment before speaking, knowing that words would have failed him, had he have spoken a moment ago. Regardless of the pause, his voice still trembled. "I'm not going to let you die for me. What good will that do anyways? You're saying that I should just let him kill everyone that I care about so I'll be left alone, with a guilty conscience that tells me that I had the chance to save you? No, that's not going to happen. Even if you're upset or depressed you'll still have people to turn to. I'm not leaving you alone." He stopped talking when he sensed my voice going weak again.

Yukio, however, didn't hesitate to reply again. "I need you, Rin! We don't have a mother or a father-all we've got left is each other!"

Rin sighed. Rin admits that his brother's words struck a chord with him, but not enough to let Yukio die on his watch. "I thought you were the smart brother, Yukio? I'm not actually going to die-even you know that-and if I do come back, er-different, I'm counting on you to bring me back to my senses, got it?" Rin turned to face him, one last time, and forced a smile on his face.

Yukio ignored everything his older brother said and struggled to reach him but Rin continued to walk away. With each step Rin took, he could feel pressure forming in himself and panic began to spread in his thoughts. Was he making the right choice? Would they really leave his friends and family alone? These and other thoughts flooded Rin, nearly making him stop and turn back-but he went on.

The demon smiled and grabbed Rin's swords from him, laughing. Rin's reflexes kicked in and he reached for it, but he stopped and pressed his hands to his side-there was no turning back at this point. "No use for this anymore," The demon snickered. With a large amount of pressure, the blade cracked before falling to the ground in two separate pieces. Rin stared in shock while his blue flames spread across his body-now uncontrollable. Rin clenched his teeth and looked down at the ground. Now that the sword could no longer control him, it would be impossible for the Vatican to allow him to live in peace in this world. Rin couldn't turn to look at his brother again when tears began to form in his eyes.

'Stop it,' Rin lectured to himself. 'Even though the choices were limited-in the end it came down to my decision. I will not cry.'

Rin breathed in and out to maintain a steady voice before speaking. "Goodbye, brother."

Rin noticed Yukio calling his name, screaming after him, but it was nothing but a small buzzing sound as he approached the portal that would bring him to Gehenna; the world of demons-the world he belongs in.

He stepped through the gate and all of the warmth of the human world left him instantly. Panic seized up inside him as he tumbled through this new, cold world and regret began to fill his mind immediately. While Rin was silent from fear as he fell, the demon was laughing and turned to smile at Rin.

"Welcome home, Brother, Father is waiting."
