Hello to any readers! I hope you enjoy this rather depressing story haha I suddenly came up with the idea for this and decided to go with it, I guess I like seeing my favourite characters in pain or something haha anyway, I don't think this will be a very long story, probably only a couple of chapters so I'll try to upload weekly. Don't be afraid to ask any questions if something needs clearing up! :)

Yaoi pairing: RinXBon

I do not own Blue Exorcist.

It's good to see everybody again!" Yukio smiled as he walked up to the group of ex-students, receiving various waves and greetings. "How's the job been treating you, now that you're all exorcists?" It had been some time since they had graduated and became full exorcists, all separating and following their own paths. Today was supposed to be the big reunion after many years.

"It was hard at first but I think we've all gotten used to our roles now." Bon replied honestly, a satisfied and proud smile on his lips. Everyone agreed with a nod.

"I'm so happy to be back with you all!" Shiemi squealed excitedly and clapped her hands together, a little green demon sat cutely on her shoulder. "Yeah guys, it's been so long!" Izumo said, earning a group of surprised faces. "Not that I missed any of you or anything." She crossed her arms and pouted, her cheeks slightly red. Shima chuckled, running a hand through his pink hair, slightly longer than before. "Aww but I missed you, Izumo!" He grinned and Yukio rolled his eyes. Still a massive flirt.

Everyone was laughing, sharing memories of their school days and discussing what they'd been up to in the last couple of years when Konekomaru noticed something was off. "Hey, isn't there someone missing?" He asked, stopping and looking around. This is when everyone realised that someone wasn't there, someone very important. Shiemi was the first to ask. "Yeah, Yuki, where's Rin?" Everyone looked at Yukio who stood there with a frown, his blue eyes sad and stuck to the floor. With a sigh, he pointed behind him. "He's…over there." Everyone looked over their former teacher's shoulder to find a lone Rin sitting under a tree on the school grounds, his expression completely blank as he stared forward with his sword resting next to him. Even his tail held no movement, it just laid there on the grass.

Everyone stared and frowned at each other. "Why isn't Rin coming over? Does he not want to see us?" Shiemi asked, her voice catching slightly. "He hasn't seen any of us for years and this is the way he behaves?" Izumo complained as she crossed her arms over her chest, offended.

Bon tutted and shook his head, taking a step forward. "What the hell is that pale ass demon trying to pull? Skipping out on us, eh?" Before Yukio could stop him, Bon was storming across the grounds towards the son of Satan, mumbling to himself about how he would stand for Rin's attitude. Upon reaching the dark haired demon, Bon crossed his arms and glared down at Rin.

"What the hell is your prob-" He started but completely froze when Rin looked up at him. The young demon's once brilliant blue eyes had faded to a dull navy colour, like the life had been completely sucked out of them. They held no emotion, no happiness, no pain, completely blank. His usual cheesy grin that Bon remembered so well, now a distant memory on Rin's thin and slightly cracked lips. The boy was like a zombie. Thin and pale with dark shadows under his eyes that seemed to envelope his entire face. Bon couldn't even speak, he didn't know what to say. The Rin that he knew, the one he'd fought with over and over again, the one he'd formed a friendship with, the one he eventually came to love and miss, was completely gone without a single trace.

Feeling a hand on his shoulder, Bon turned to look at Yukio, both with equally pained expressions on their faces. "Yukio…wha-"

"Leave him be." Yukio glanced down at Rin with a frown before turning on his heel and walking away, quickly followed by Bon and the rest of the group.

Once out of earshot of Rin, Bon swiftly turned around to face Yukio, practically pouncing on him. "What the hell happened to him?" He almost yelled, tears welling up at his eyes but refusing to fall although Shiemi was already crying. "Yeah, something is defiantly wrong with him. His face looked…lifeless." Shima added, joining everyone as they looked at Yukio for an explanation. The exorcist sighed and nodded, gesturing for everybody to sit down on the grass as he did so himself.

"Two years ago, shortly after you all graduated, me, Rin and a few others were sent on a mission. There was this house that had apparently been taken over by a demon so it was our job to investigate. When we arrived at the house, we decided that we'd send Rin in first so he could signal with his flames if he found anything. We all thought it was pretty good plan and Rin agreed with it so in he went." Yukio smiled sadly, knowing what was coming next. "Ten minutes later and he hadn't come out yet so we decided to go in after him. That's when he screamed." A slow tear rolled down Yukio's cheek, taking a deep breath, he carried on. "It was horrible. So full of pain. I'd never heard him scream like that before. It sounded almost inhuman. To this day, I still have nightmares about that scream…. Anyway, by the time we reached him, he was completely alone. The house was deserted, no other demon in sight. He's been like this ever since. He doesn't sleep, doesn't eat and rarely ever talks. He just stares. There's no emotion left in him. Even in combat, he doesn't show any anger or fear. He just follows orders with a blank face, like a machine. No one knows what happened in that house but he hasn't been the same since." Everyone stared at Yukio in shock as the male tried to get a grip on his emotions. Bon couldn't believe it, no one could. Rin was always full of life, always making jokes and in full spirits. No one ever imagine he'd end up like this. Lifeless. Cold. Broken...
