Chapter 22

Rin was so blindly angry he just wanted to let his flames loose and burn something to a crisp. He was starting to scare himself. The power he had at his call was dangerous and deadly but so alluring. When he felt it flow through him he just wanted more. He loved the rush it gave him. And the need to use it, to let go, to control everyone around him was so strong. Rin was afraid of himself.

When he finally calmed down enough he realized he just made a fool out of himself. Bon was just concerned and when he was worried he tried to hide it behind anger. Rin knew it. Yet the other boy always managed to get on his nerves. For now it would be best for them to avoid each other. The last thing he wanted was to hurt him. Or scare him off.

Rin hid away and decided to try and train his flames again. Gabriel couldn't help him so he had to figure it out on his own. The next few days he sneaked around, using his sharp senses to avoid seeing anyone. He knew they were probably worried about him but he needed to concentrate.

Soon he found a nice routine for his training. First, Rin used all meditation exercises Lily taught him so he could calm down completely and listen to his body. Slowing his breath he just sat there for a long time. When his emotions were under control he let his angel side take over and fill his mind with familiar blankness. He didn't enjoy the feeling but it was for the best.

Then he took out three candles, like he did long before, when he first tried to tame his flames. It seemed like forever has passed since then. A lifetime maybe. Still, with Satan's powers on top on his own it was just as hard as then to light two of the candles without burning them to a crisp. He needed to be precise to succeed.

Finally after managing to light the candles to his liking Rin changed location and went outside. He made sure no one was around and took off in the air. Stretching his wings felt relaxing. He flew around for a bit and found a place away from main buildings, with some old shack standing on the side. Rin knew nobody was using it anymore and it just contained some junk. There, he practiced his flames again, sending them toward the old wall and trying not to do much damage to it.

At first he was bad at it. He wanted to leave a small burn on the wall – so the flames had to be hot enough – but not a big hole like he did before. It wasn't easy to make his flames do exactly as he wanted, to make them do an amount of damage he was interested in.

When he was too exhausted to continue, he sneaked into his old room. He didn't want to go back to his and Bon's place. Not yet. He wasn't ready.

The next day Rin did exactly the same.

It took him four days to be satisfied with his control and show his face to anyone again. Rin knew that it could still shatter if he was made angry enough but was determined to keep his cool. He let his golden flames out in the front of his mind and let the calmness guide him.

Yukio was irritated with him when he finally shown up. But when Rin explained he was training so he won't lose his cool again, his brother understood. Gabriel complemented him on his progress saying he looked better. Before he seemed to be a ticking bomb.

Bon was still pissed at him and when Rin came up to him, wanting to apologize, he just shook his head and left before the demon could open his mouth. He didn't show it but it hurt him. He was afraid his boyfriend had had enough of his problems. Rin didn't know what he'd do if that was the case. Too scared to go after him and actually ask, he let him be for now. Bon would come to him when he was ready to listen.

Meanwhile a man in an elegant, black suit walked through the city, a smirk on his face. His tailored suit and red tie looked out of place in a busy, tourist spot. He moved with a dangerous grace and the crowd somehow sensed it, letting him pass without a problem. Soon, he arrived at his destination.

He stood in front of a big fountain, enough of open space around him for what he needed. Suddenly, out of his sleeve a blade fell into his open palm and with a whirl and a feral laugh he slashed at a woman near him. Panic erupted in the busy place. It was too late to run, though.

Shiny, red blood flowed out of wounds the demon made, screams and laughter filled the air. A chant soon followed and the blood swirled around like a snake, following his words. A circle was painted on the pavement, elaborate swirls and curls making the design. The man grabbed a child in his arms just after killing it's mother. The kid cried and struggled but the iron grip never loosened. Suddenly, a cry was cut short as blood flow from the child's throat, making a pool in the middle of the circle. The man let go and stepped out of it. He watched in glee as a small Gehenna Gate opened. It was not as big as he hoped but now the only one who could open a bigger one was their new king. Unfortunately he wasn't keen on killing humans. Pity.

Alarms blazed through the Academy. Everyone gathered in the main Hall, waiting for Mephisto to tell them what was happening.

"Everyone get ready." Headmaster spoke and nervous silence fell around them. "A Gehenna Gate got just opened in a busy square in the city. A small army of demons got through and are killing people as we speak." An angry murmur flowed through the air. They thought it was over. Apparently not. "Exorcists are to divide into their usual groups and spread throughout the city. We need to take back control and save as many people as we can. Move!" He ordered and everyone obeyed with frantic movement.

"Rin. Please come here." Mephisto asked him when he noticed Rin was ready to go and kill everything standing on his path.

Rin was so angry all of his previous training was useless. His body erupted with blue flames and an atmosphere around him screamed death. He snarled at Mephisto's try to stop him and simply took off. It was his responsibility. His demons decided not to follow his orders. He will show them what it meant to disobey their knew king. With a powerful flap of wings, he was gone.

Mephisto sighed. He hoped Rin won't get too carried away. He felt a gentle hand at his shoulder.

"Don't worry. He might be angry now and out of his head but I believe in him. He will realize in time he need to stop." Gabriel said, his voice sure.

"I hope you are right. Because with power like his... no one would be able to stop him. I only hope he himself still can." Mephisto leaned back against his partner. He was so glad he had him. He gave him strength.

When Bon, along with Yukio and the rest of their group, finally arrived at the Gate the scene was already looking like taken out of a horror movie. The Gate itself was gory enough, obviously created with human blood and flesh. In the middle of it a black substance swirled and from time to time a demon escaped through it. Around it, bodies of men, women and children laid abandoned and still bleeding. Some violent demons were still ripping them apart after they died or were drinking human blood. A fury of blue flew around them, killing everything it touched.

Bon was so scared. Rin didn't look like himself at all. He snarled, his sharp teeth bared, slicing at every demon with his sword, flames hugging his body. He didn't even have to send them out, they were burning so hot bodies turned to ash when he got near enough. The demons that weren't stupid tried to escape and the exorcists easily took care of them. Rin killed his lion share though.

Finally, when there were no more demons around the square, Rin moved towards the Gate and with a quick, powerful slash of Kurikara he destroyed it.

Instead of landing, Rin flapped his wings and went deeper into the city. The group decided to follow him to see if they could help. The people here were all dead, nothing could help them anymore. Bon tried not to look as he moved around the bodies.

Rin flew around, using his senses to find every demon. He didn't care if they were killing anyone or not. Every demon unfortunate to cross his path got burned or sliced to death. Exorcists followed him, helping were they could but kept their distance. No one knew if Rin wouldn't attack them too.

Finally Rin managed to hunt down the source of the Gate's power. The well dressed man didn't stand a chance.

"You! You are the one who opened the Gate! How dare you!" Rin snarled at him and pinned him down with two well aimed gold rays. The demon screamed in pain at they pierced his shoulders and stuck him to the ground like a butterfly with a needle. It burned.

"Wasn't I clear enough when I ordered not to kill humans?! And you decided to open the Gate and let those mindless beasts roam? No. I will not allow that!" Rin was so angry he saw electric blue everywhere.

The man smirked even though deep down he was terrified.

"You think I am the only one! Ha! There are countless others that wish to take over this world. I am just the first brave enough! My failure won't stop the others so go ahead and kill me. Sooner or later they will make their move and you'll see you are powerless to stop them! We won't listen to a kid with stolen power!" He spat at him and Rin snarled in anger, twisting the ray in the demon shoulder until he screamed in pain.

"Rin... let us handle it. You caught him. Let us take him to Mephisto so he can face trial." Yukio tried approaching him but a wall of flame stopped his steps. He gasped. It was nothing like before, when Rin trained with him and the flames were just warm. No, this wall was burning so hot he had to take quick steps back so his skin wouldn't blister. It hurt. "Nii-san! Get a hold of yourself!" He shouted. Rin ignored him.

"I will make an example out of you." Suddenly, his voice wasn't angry. It was almost too calm. And cold. So cold. Bon trembled hearing it. So did the pinned demon. "You will beg me to kill you when I'm finished with you!" The flame wall between him and the exorcists lowered enough so he could face them. Steel cold blue eyes met first Yukio's and then Bon's gaze.

"I am going back to Gehenna. This was a bad idea. They will never listen and never obey if I am not there. I will make sure this won't happen again." Then his eyes softened a little when he looked into Bon's eyes. "I'm so sorry." He said and it was like old Rin was back. Bon gasped, seeing the pain in his expression. "I'm so sorry Bon. I cannot stay here and I don't know if I'll ever be back, they are out of control. It is my responsibility to stop them. I can't do it from here. Don't wait for me." He stated and Bon gaped at him.

"What?! No! You can't be serious! I just got you back... I'm sorry! Please, don't leave me. Just promise me you will come back and I will wait for you! I will wait!" His voice was desperate. Rin closed off his pained expression. He needed to do this, it was for the best. He couldn't expect Bon to wait for years for him. Because now he realized that it will take much, much more time than a few days to make those bloodthirsty beasts obey him.

"Bon. It's over. I am not coming back. Get on with your life. Goodbye." He nodded towards his shocked brother and grabbing his prisoner, disappeared. Bon's pained eyes already haunted him.

Bon felt like his whole reason to live just got ripped away from him. Well, it was. What was he supposed to do now? He felt tears falling down his cheeks.

Yukio stood there, still in shock. He understood Rin's decision but that didn't mean he agreed with it. Realizing it was probably the last time he saw his brother, he let out a pained sigh.

Following days were filled with trying to control the situation after the attack. A lot of people died or got terribly injured. They were also terrified and unable to accept what they saw. Healers were busy walking around and helping while other specialized exorcists modified the victims memories.

Bon sat with Kuro in his room, staring numbly into space. He couldn't believe Rin just left him for good. He still expected him to walk back through the door and kiss him better. He didn't.

Meanwhile, Shiro was never happier to see his son, even if his deadly nature shown it's ugly head again. The exorcist was unable to control the angry crowd of demons and was almost defeated by them. Rin's arrival stopped the beasts from tearing him to pieces.

Quickly, Rin had Amaimon gather everyone intelligent enough to be able to listen to him. He had the demon he arrived with tied up so everyone could see him.

"This is a traitor. This demon here decided to disobey my orders and opened a Gate in Assiah. He told me he's not the only one. Well, look at what happens to people like him and think twice before you decide to betray me. I will always find you. And I will always treat you like this." After saying that, Rin summoned another sharp ray of his angel power and slashed slowly at his suit so it fell in tatters to the ground. Then, he pressed it very lightly to the demon chest. He only grunted in pain as Rin swirled it around. Suddenly, he added pressure and the demon screamed as it pierced and burned his chest.

Shiro paled seeing his son torture the demon with a stoic face. He knew it would be effective against every demon who thought about disobeying but still... this was awful. Even Amaimon was repulsed by it.

Soon, the demon was unrecognizable. He started begging for death some time ago and only his voice penetrated the deadly silence. Rin stabbed his body in various places, never to kill only to give as much pain as possible.

Finally when the bloody mess of the demon couldn't even beg anymore, Rin set him on fire with his flames. He made sure he would burn slowly. His screams filled the air again. When the lifeless body fell to the ground, it looked like scorched flesh.

"I hope you understood the message. As long as you are killing each other here, I won't interfere. Do whatever you want. But the moment you choose to take your blood-thirst out to Assiah... Be sure I will find you and I will make you beg and cry like I just did now. You are all dismissed." The demons couldn't get away fast enough.

Rin's little show got the message across. Don't mess with the new boss. Still, an echo of disagreement at the situation could be heard. In the following weeks Rin was busy moving around and scaring anyone who even thought about misbehaving. At free moments he missed Bon. The way they parted... they were still fresh after a fight and Rin never go a chance to apologize for that. Still, it was better to part in anger and disappointment than leave Bon with fake promises. It was better for him to be angry so he could move on easier. Bon could not possibly wait years for him. He already waited a whole year... The logic of it didn't stop the longing though. And the fact his own father seemed to be afraid of him now didn't help his mood.

It seemed every relationship he had crumbled again. It was over with Bon. Shiro was afraid of him and displeased with his torture show. Amaimon avoided him and tried to keep him as far away from Anastasia as possible. And he was sure Yukio was disappointed with him leaving like that. Rin was left alone with his flames and couldn't be more miserable. Yet, he carried on because now he had a great responsibility and couldn't just run off.

Slowly the situation in Hell got under control. Repairs started to rebuild the city back to it's previous glory and less aggressive demons and souls started showing up around the streets again. Business started once more and life seemed to move on. Shiro moved out of the castle in an excuse of helping with rebuilds but Rin knew his father was disappointed with his behavior and wanted to get away. The king lived alone in his empty castle.

A month passed since he last saw Bon. His heart grew cold in an absence of his mate. Rin moved around the place restlessly not knowing what to do with himself now that the situation was more or less under control.

"Rin!" Amaimon voice woke him up from his daydreams. He looked towards him curiously. He didn't see his demon brother for some time.

"Yes? What is it? Did something happen?" He asked, worried. He was so depressed he didn't want to go out and punish some demon for idiocy.

"Yes. It would be best if you came and see. I'd rather not be the one to tell you about this..." He said and it got Rin worried even more. Amaimon was never scared of him yet now he looked about ready to bolt. He stood up and followed the Earth King. What could be so bad?

"We found him being tortured by some idiots. I took care of them for you. He'll be fine."

Amaimon gestured into one of the rooms Anastasia had for her patients. She kept up the healer work and was quite good at it. Suspicious, Rin entered and Amaimon made his escape.

What – or rather who – he saw on the bed all beaten up made his heart almost stop in fright. He couldn't believe his eyes.

"BON?! What?! No... why? Why are you here?" He asked, panicked, moving towards him. His hurt boyfriend – ex-boyfriend he reminded himself – looked up at him with hope.

"Rin... I am so glad I finally found you..." His voice was weak. His face sported purple bruises and his chest was bandaged. His arms had nasty slashes all over his skin.

"How are you here?!"

"I... please don't be mad at me! But I couldn't stand it! I tried, I really did! But I just couldn't!"

"Wait... what are you saying?" He asked, even more panicked when an idea came to his mind. But no, Rin thought, Bon didn't... couldn't...

"I'm sorry. I know you wanted me to move on but I just couldn't. I love you, you bloody idiot! Flames or not, devil or not, I love you! I don't care how angry you get or how out of control. I simply can't live without you. You idiot, you made me so dependent even on the idea of you that when you took my hope of seeing you again away... I couldn't cope. I knew how Shiro got here... so I shot myself to get to you." He finally admitted and Rin felt the air leaving out of him. He dropped down on a chair and just stared at him.

Bon fidgeted under his heavy gaze and started babbling again.

"You were gone for weeks and it was chaos and everyone just wanted to help people and focused on that but I could only think of you. That you are all alone with demons you had to control when you had problems controlling yourself and I knew you struggled and I just wanted to help you with this and be with you and I missed you...!" The words left his mouth with a rush and suddenly Rin moved again. He leaned down, grabbed his shoulders to pin him down gently to the bed and stared into his eyes, his burning gaze close to his. Bon gulped.

"You. Fucking. Moron." He didn't say anything else and captured his lips with his own. How could he stay angry at him when it was obvious Bon missed him just as much as he missed Bon. There was no sense to stay angry at him when the deed was done and there was nothing he could do about it. Rin made his choice to leave. Bon made his choice to follow him into the dark. What mattered was that he wasn't alone anymore, the deadly prince in a ghost castle, ruling from afar. He had his hope and his reason to live here in his arms and he decided to never let it go again.

The future might not be bright and easy but now Rin knew he would make it. He was ready to face it because he had his mate here at his side where he belonged.

They would be just fine.

The end
