Unbreakable Bond (Rin Okumura x Reader) {Soulmate!AU}

"I love you not only for what you are but for what I am when I am with you."

From the moment you met him, you couldn't stand him.

Rin was nothing more than a novice exorcist who believed himself to be more adept at fighting than everyone in his class, you included. As someone who trained their whole life to vanquish demons, pushing aside all luxuries in the process, you were quite offended by his arrogance.

He knew nothing of all the pain you went through growing up; how many loved ones were stolen from you by demons. Your whole family was gone and you were the only descendant left, the sole remainder of the [last name] legacy. You would rather be damned than to allow yourself be overshadowed by someone like Rin. So you challenged him to a fight.

And it was that fight that changed everything.

It was obvious you were far more skilled in fighting than he ever dreamed to be which was why it was so easy for you to defeat him. But somewhere amongst the chaos of battle, you and he made skin-to-skin contact for the first time. It was at that moment that the two of you froze in place, eyes wide in realization.

You had found your one and only soulmate.

Every shed of hatred you held for him dissipated at that moment. You couldn't bring yourself to hate him anymore. If anything, you were grateful for being able to find your soulmate; the one thing that some people go a whole lifetime without ever finding. It didn't matter to you anymore how irritating Rin could be with his false sense of arrogance.

After several quiet seconds passed by, you finally dropped your weapon and your knees buckled. Before you could hit the ground, he caught you in his arms.

"Are you okay?" he asked worriedly. "[name]?"

You looked up at him with unshed tears shining in your eyes. A rare smile was shown on your face; a smile of yours he never before saw directed towards him. "I'm not imagining this, am I?"

He laughed, fully understanding what you felt at that moment. "Looks like you'll have to continue putting up with my annoying ass."

Months flew by after that moment, but they felt like mere days to the two of you. Your fellow classmates found it amusing how the two people who hated each other's guts were now so undeniably in love. In all honesty, you found it amusing as well. After all, fate works in mysterious ways. That could never be doubted after discovering his secret.

You made sure that Rin knew everything about you whether it be your favorite color or darkest secret - ones that not even your closest friends knew of. He told you much about himself such as his childhood or how his father died at the hands of Satan. Even so, it was obvious there were still some things that continued to remain hidden.

Despite your growing curiosity, you never dared to pressure him. You knew there would eventually come a time when he told you and until that moment came, you were willing to wait. After all, there must be some reason for him to keep a secret from you. You just never realized how big that secret would truly be.

In the end, you accidentally discovered the secret yourself. You woke up one morning to him sleeping beside you, his sword you never once saw unsheathed lying just mere feet away. Your curiosity overwhelmed you to see what the sword looked like; to see why he never once used the sword in battle. You never once realized what dark secrets a mere sword could contain.

Rin woke with a start the moment the sword was unsheathed. You took a step back and dropped the sword in the process, but the mysterious weapon was no longer your main focus. You were far more concerned with the blue flames that engulfed his entire body.

He scrambled out of the bed and sheathed the sword, putting a cease to the blue flames. Every part of your brain repeatedly told you to scream for help, but your breath was stuck in your chest. Although the blue flames were now gone from his body, you could still see them playing on loop in your mind at the memory of your family being viciously slaughtered by demons and by Satan himself.

"You...," you managed to choke out, no other words coming to mind. The message came across clearly to him, though. He knew far too well that you were no fool - you knew what those blue flames meant.

And so he finally divulged to you, the person he loves most in this world, his darkest secret: he's the son of Satan.

"I'm so stupid!" he cried as he ran his hand up his face, grasping his dark hair within his fingers. "I should've just told you from the beginning, [name], I'm so sorry. I'm nothing like him - I hate him! I want to kill-"

You cut him off with a kiss. His eyes grew wide and his body went rigid as his mind tried to process the scene before him. Rin's fear that you loathed him slowly washed away with that tear-filled kiss.

Common sense screamed at you to kill him right on the spot. After all, he was the offspring of one of the evilest creatures in existence, yet you managed to drown out those dark thoughts. Your emotions, which you've always worked so hard to suppress, were finally finding their way back up to the surface of your mind and were clouding your acumen.

The bond shared between soulmates was far stronger than the mind.
