Demons and Ghosts, Hell's King and King of the Dead: What If?

What if Clockwork had allowed Rin to change the past?

Rin appeared in a flash of light, looking at his father and himself on the other side of the roof.

"I can fix this..." He murmured, flipping up his hood, letting his tail hang free.

Rin raced toward the two with inhuman speed.

He wasn't subtle, he didn't try to be. His only priority was to save his dad.

Shiro and Younger Rin turned to look at him, eyes wide.

Neither was able to react as Rin grabbed Younger Rin's arm and leapt into the air, through the roof, yelling, "Sorry! You can have him back later!"

Younger Rin struggled, but with Rin's full demonic power unleashed and not sealed, even his human form was stronger than Younger Rin.

Rin didn't waste time in surrounding him and his younger self with blue flames, teleporting them a few miles away from the monastery, because Rin knew that Shiro would come after him.

They appeared in a forest, and Rin let go of Younger Rin.

Younger Rin stumbled back, wide eyed with fear.

"Who are you? You're a demon, aren't you? You want to take me to Satan!" Younger Rin scowled, but the fear in his eyes was unmistakable. "But the old man said blue flames are the sign of Satan! He told me I was the only one who possessed them besides Satan!"

Rin himself remembered the same fear his younger self was experiencing.

"I'm a demon, you're right about that, but I do not want to take you to Satan. That's the last thing I will ever do, trust me. Right now, I'm trying to save D-Shiro." Rin sighed.

"What's that supposed to mean? Save the old man?!" Younger Rin asked, eyes narrowed.

Rin sighed, slipping off his hood and staring his younger self in the eyes. He was glad he was in human form.

Younger Rin gasped, stumbling back. "You're...me?"

"With a few deformities," Rin answered, "But, yes. I'm a demon, though. Look, I'm you from the future. In my time, Shiro died because of you...me...us."

"What...do you mean?" Younger Rin swallowed.

"I got angry, I was mad Dad kept the truth from me my whole life, and while it wasn't the right thing to do, he was only trying to protect me. I yelled at him, told him to never call himself my father again. He slapped me, but inside, his heart broke at my words. His will wavered, and that was just enough for Satan to possess him. Shiro took control just in time to stab himself and save me. I unsheathed Kurikara in my panic to save him. While I closed the Gehenna Gate, I lost my dad, and became half demon," Rin explained.

Younger Rin teared up. "No..."

"I came back to fix that, to give you another chance to have a father. I don't know if this will change my own future or if it will only change yours, but either way, it doesn't matter to me. If it only affects you, then I'm glad I managed to save at least one version of myself from a whole load of emotional turmoil and pain." Rin sighed.

"I-" Younger Rin didn't have a chance to speak as his future self was thrown into a tree.

"Rin! Are you okay?! We have to go, now!" Shiro barked, grabbing his son.
