Yukio ran towards the Demon that was currently trying to crush his brother under it's massive hoof. Rin was screaming and coughing up blood, in fact it was so much like that day that the brown-haired half-Demon froze just as he reached his twin, the sight of the blood making him choke on his breath. Unfortunately, his timing was horrible, "worthless pest! Didn't I tell you to go away!" the Minotaur Demon roared, smacking him away with his tail once again. This time he was thrown towards his students and also, the Kurikara. "Yuki!" Shiemi cried. "Hey Teach, you okay!?" Suguro demanded, as they helped him up. As Yukio got to his feet again, he looked up, seeing the blue flaming sword right in front of him. He reached out a hand for it, 'should I- no, no, I can't, what if I can't control myself this time?!' Yukio thought, worried. Suddenly Rin screamed in agony as the Minotaur stomped on his tail before going back to crushing his ribs. "Rin!" Yukio cried, terrified as he watched the Demon crush his brother to death. He shook his head, 'no! damn it, I don't have time to hesitate! If I do, Rin will die! I'm going to lose the last family member I have to my own fear! I won't let it happen!' he thought, reaching up and gripping the handle of the sword.

The Demon was enjoying himself immensely as he slowly tortured the disgrace of a Prince that had nearly killed his King. Suddenly a familiar voice called out, making him growl in annoyance. "LET HIM GO!" "How many times do I have to-" but he was cut off by the sight of the younger Okumera Brother gripping Kurikara's handle tightly, blue flames surrounding him. Yukio's ears and fangs had grown longer and his long brown tail was free of his pants, whipping around with blue flames flaring at the tip. The brown-haired Demon growled lowly "I SAID LET MY BROTHER GO, RIGHT NOW! OR I WILL KILL YOU!" Yukio roared, barely keeping himself under control. So this is what it was like for Rin. He made a promise to himself to stop hassling his twin about his self-control so much. "Oh really? You're going to kill me? Don't make me laugh you damn brat. Now wait your turn!" the Minotaur Demon replied, turning back to Rin as he did. Yukio glared at the monster, who dared to hurt his brother so badly. Before he could think about it, he found that his body was already moving. His opponent snarled and tried to knock him away again, but the brown-haired Demon dodged his fist, aiming to drive the sword into one of the places unprotected by demonic flames.

However, the Demon's huge tail again whipped out and knocked him back. He laughed, "you're not used to close-range combat are you? Even less with fighting with a sword! It's so obvious that you have no idea what you're doing, honestly, it's utterly pathetic! Not to mention insulting! I can't believe you were the ones who put my King into such a state. But I won't let you insult him any more with your weakness. I'll end you both today!" the Minotaur charged forwards and tried to impale him on his horns. Meanwhile, Bon was pulling Rin to safety, "nice job Teach. You distracted him long enough for us to get to Okumera" he muttered under his breath.

In the air above the fight, Mephisto sat in his floating chair, Amaimon in hamster form on his shoulder and a cup of tea in his hand, "well, well, I came back as soon as I realised something was wrong, only to find this." He looked down at his youngest brother as he fought the Minotaur Demon with all he had. Watching the way Yukio's flames were flaring up, the King of Time smirked, "he's starting to lose control of his emotions. Back when Yukio was human, he was always calm and composed in a fight. But now he's facing an opponent that he has no idea how to defeat, can't seem to hurt and who has already hurt Rin badly. All of this stress and anger is going to reach a boiling point soon, though I must commend him for being able to stay in control for this long. And when he loses control- BOOM!" Mephisto proclaimed, throwing his hands up dramatically. Amaimon turned to look down at where Shiemi was attempting to help with Rin's wounds, "Rin Okumera doesn't seem to be doing very well either big brother" he added. "Well, his chest was nearly crushed" Mephisto replied. He looked down at Yukio, who was slowly losing control of his emotions and flames, "what are you going to do little brother? Now that you're the one whose losing control" he asked himself.

Blue Exorcist

Yukio was struggling. Not just against the Minotaur Demon, but against himself. He was furious at the monster, and he could feel that fury threatening to overwhelm him. He shook his head, 'no, stay calm, stay focused. I can't lose control now, or everyone else will be in danger!' he thought, glancing behind him where Rin was recovering with the rest of his students, 'I have to protect them!' he thought. Seeing Rin in that state sent a bolt of white-hot fury coursing through him, but he gripped his head and tried to fight it off, 'no! stop it, calm down!' Yukio groaned. Before he could focus back on the fight, a fist was buried in his stomach, making him gasp in pain, "you're weak. And because you're weak, you'll have to watch them die now!" the Minotaur roared, grabbing him by the throat and dragging him over to his students and brother. Yukio struggled against the iron grip, but his strength was no match for his enemy's.

The others noticed the Demon's approach and got ready to fight, while Shiemi pulled Rin close to her, holding him protectively, like she had during the Training Camp. However, like with Yukio, all of their attacks proved ineffective against the Minotaur Demon, and he just knocked them all away easily. Shiemi was the last to get knocked away, as she clung tightly to Rin and refused to let him go. She glared up at the Demon threatening her dearest friends and possible boyfriend, "leave Rin alone and let Yuki go! They didn't do anything to you!" she cried. "Awe, how sweet, are you this brat's Mate?" the enemy mocked, indicating Rin. Shiemi didn't let up on her furious glare, determinedly staying put. "R-run Moriyama! He'll kill you!" Shima cried. But still, the girl held her ground, "Rin is precious to me. And so is Yuki. And I won't let you hurt them anymore!" she yelled. Nii jumped off her head and formed a protective barrier of Rohan around the two. "Ha! You think that will be enough to stop me? Think again you pathetic girl!" the Minotaur smashed the barrier to pieces with his fist, only to see no bodies underneath the branches.

Looking around, the Demon couldn't see his prey anywhere. "Damn, I can't believe they got away. Oh well, then I guess I can kill the rest of these worthless humans in the meantime" he chuckled. "n-no! don't!" Yukio rasped, still being choked in the Minotaur Demon's massive fist. "Oh, don't worry. I won't kill you yet. You'll get to watch me kill both of them before I kill you" he replied with a wicked grin.

Meanwhile, Shiemi cradled Rin in her arms at the top of a tree, Nii keeping the both of them safely anchored to the branches. "Oh no" she muttered, tears welling in her eyes as their enemy slowly began to walk towards her classmates, still choking Yuki in one hand. "what do I do now? I'm useless, always needing help from Yuki and Rin. But when they need me, all I can do is run away!" she sniffed, beginning to cry quietly. A movement in her arms brought her attention down to Rin who was slowly beginning to stir. "Rin?" she asked softly.

Blue Exorcist

Yukio was running out of options and time. More than that, his control was slipping away. He was being choked to death by the Minotaur Demon while he was heading to start killing his students, and still intended to kill Shiemi and Rin. The stress of the situation, along with his frustration and fear was beginning to overwhelm him. "P-please, no! Leave them, alone!" he begged, struggling against the other Demon's massive strength. "Oh don't worry. I'll make sure that you'll all see each other again very soon!" the Minotaur sneered, aiming a punch at Izumo. "I humbly appeal to thee, oh Goddess Inari! Grant my request! Leave not my prayers to the unfulfilled!" the purple-haired teenager cried, reciting as fast as she could. Uke and Mike appeared and attacked the enemy Demon, only to be punched away easily. "Is that the best you can do?" he mocked. As the Minotaur prepared to kill Izumo, something snapped inside the younger Omumera twin, "I SAID STOP!" Yukio screamed, gripping the Demon's arm with both hands and squeezing as hard as he could. The Minotaur screamed as the younger Demon crushed his arm. Everyone gaped as their Teacher was dropped to the ground. "I swear, I won't let you hurt them ever again!" Yukio screamed, enraged as his flames grew even stronger than they had been before.

Mephisto smirked, "well, well, it seems our ever calm younger brother has finally snapped!" he exclaimed excitedly, watching as the boy snarled ferally at his opponent. "Do you think he'll be as fun to play with as Rin Okumera Big Brother?" Amaimon asked. "Perhaps, but remember what happened the last time you pushed that boy too far. He almost killed you, twice" the King of Time reminded his younger brother. "True, but the younger one has only just awakened his power. He'll at least be a bit fun to play with for a while" the green hamster replied. The two Demons then turned back to watch the fight.

Blue Exorcist

"Damn you, you filthy half-breed brat!" the Minotaur screamed, furious and in pain. Before he had a chance to retaliate, Yukio kicked his leg so hard that the bone snapped, forcing him to drop to one knee. "I'll kill you!" the enemy Demon roared, punching the ground so hard with his uninjured fist that huge pieces of the earth came lose and attempted to crush Yukio. But the smaller Demon dodged them easily. After the ground had stopped shaking, the brown-haired boy picked up a lose piece of earth and threw it at his enemy. Before it could hit, it was smashed away by the Minotaur's tail. "I am going to torture you to death. Slowly, painfully. And even when you scream for mercy, I still won't kill you. I'll make you regret ever having been born you disgrace!" he roared. Yukio growled in response.

Rin groaned as he slowly woke up, "oh, God, I feel like I was hit by a bus over and over again!" he muttered, opening his eyes to see a teary Shiemi smiling at him in relief, "oh thank goodness, you're okay!" she cried, hugging him tightly. "Ow! My ribs are still tender Shiemi!" he yelped in reply, making the blond girl instantly loosen her hold, "oh! Sorry! I didn't mean to hurt you more, I promise!" she exclaimed, ashamed. Rin slowly sat up with the young girl's help, "what happened to that Demon?" he asked. Shiemi opened her mouth to explain, only to be cut off by a furious scream from down below. Rin, recognising the voice instantly, though never having heard it like that before, crawled to the edge of the branch they were on and peeked through the leaves. What he saw made his eyes widen in shock and horror. Yukio was surrounded by blue flames, ears and fangs large and sharp. He was currently on the Minotaur Demons back, arms wrapped around it's throat, slowly crushing it. But what really caught Rin's attention was how out of control his brother seemed. His flames were going everywhere, burning the grass under them to ashes, face filled with fury and eyes- his eyes looked just like Satan's, just like his when the Kurikara was nearly broken. "Oh shit! This is really, really bad!" the indigo-haired Demon moaned.

He moved to get out of the tree, "I have to stop him! Calm him down before it's too late! If I don't, he'll go after the others next! Damn it, where the Hell are the teachers!?" Rin growled, furious at himself for letting things get this far. Shiemi tried to stop him, "Rin wait! It's too dangerous, and besides, you were really badly hurt before!" the blond-haired girl cried worriedly. "Don't worry, my injuries are already healed. Besides, Yukio is my younger brother. But he's always been protecting me. Like I said before, it's my turn to protect and help him. I need to step up and act like an Older brother should. And right now, I'm the only one who can stop him before he goes completely out of control" Rin proclaimed, jumping out of the tree, and running off to find the Kurikara. Shiemi watched him go, "please be careful Rin. Please" she prayed.
