"You bastard! Leave Yukio out of this!" Rin yelled at the green haired male who was stepping on Yukio's back, immobilizing him.

"I've searched the whole place for you. I finally found you, brother." Amaimon said in his usual, monotone voice. He left Yukio behind and approached Rin once he noticed and recognized the young child in his arms. "What have they done to you, aniue?"

"Step back! I'm gonna kill you!" the hald demon screamed, baring his sharp fangs at Amaimon. "N-nii... chan..." Yukio tried to call out for Rin. The green one didn't pay attention to Rin's warning; He came even closer, instead. He leaned forward to observe the shivering toddler since he was a bit taller than Rin. Simultaneously, the twins immobilized the demon king; Rin extended his free arm and wrapped his hand around the older's neck, while Yukio was pointing his revolver gun at the back of his neck. Cerulean eyes flashed, full of fury. His strong hands got wrapped around both Rin and Yukio's arms, stopping them dead on their tracks. Yukio's gun fell on the floor and Rin's hand unwrapped itself around Amaimon's neck.

"You are no match for me. Give me my brother." what the Earth King didn't expect, was Rin's knee in his stomach. "Ugh! H-how... dare you..." Amaimon immediately let go of their arms. Yukio reached for his gun. Amaimon noticed the young exorcist's weapon but it was too late...

BANG!...

A purified bullet dug its way all the way from Yukio's revolver into Amaimon's left shoulder. The male demon screamed in agony. Mephisto woke up in Rin's arms. The demon king was on the floor panting and breathing hard "you... w-will... pay for this..." Deep down the twins knew that he ment no harm. He was only searching for his lost, older brother. From previous experience, the twins knew that when Amaimon was around Mephisto he always had that attitude of I-don't-give-a-shit-about-you. Like Mephisto's presence was enough to make him feel complete. When he was around him, he was never in mood for fight. He only wanted to be around him. In Amaimon's eyes, his big brother was like a god. In Yukio's opinion, he was like a child abandoned by his parents who was only trying to protect himself.

The bullet was quite effective. Elements of purified water were now running through his bloodstream, making him weak and drowsy. Yukio knelt beside him, checking his pulses. Amaimon couldn't attack him. He was lying on the floor, holding his injured shoulder while blood was running between his long fingers. Mephisto was wide awake now, trying to free himself from Rin's strong arms. "Where are you going Mephisto? Let's go to bed. You're sick and you should get some sleep." Rin started walking towards the other direction while Mephisto was still trying to free himself. He finally bit Rin's hand and the second one almost let him fall in the ground. "Ouch! Why did you do that!?" Mephisto, now free from his caregiver's arms, ran towards the drowsy demon king who was like a feral creature, a wolf, in captivity. "What the-" he bypassed Yukio who was running some tests on Amaimon. The young child dropped himself on his knees in front of Amaimon's face and using his small hand, caressed the weak demon's cheek. Yukio didn't interfere. He thought that the child was safe. So did Rin... for an odd reason. Amaimon opened his eyes, looking up at Mephisto. "Aniue..."

The child's eyes flashed. Not green anymore, but yellow. The brightest yellow of the world. He stood up, on his short, child-like, thin legs, not taking his eyes from the injured demon. Suddenly, a lot of things started moving in the room; Books, clothes, picture frames, paper sheets, pens, notebooks... Alongside with them, all the clocks in the room started ticking anticlockwise. All of them; Watches, alarm clocks, wall clocks... even PC and cellphones' clocks started going backwards! "Umm... Rin... I don't think this is normal" Yukio said, looking all around. Rin said nothing. He kept staring at Mephisto, instead. What is he doing!? What's happening!? What should I do!? DAMN IT!

Suddenly, both Amaimon and Mephisto started screaming in agony, synchronizing their screams... Mephisto fell on his knees, revealing his sharp canines and long, pointed ears. An appearance way mightier than his normal form. His hair had become a darker shade of purple, almost blue. His eyes, bright yellow orbs surrounded by dark skin above and under the eyes. Two lines of crimson blood were rolling down his cheeks all the way from his eyes. His pale skin was a lot of shades paler with lots of purple veins coloring it, like a corpse.

When the two demons stopped screaming in pain, the things in the room stopped moving around. Yukio and Rin couldn't believe in their eyes. They were both speechless and taken aback. Mephisto fell on the floor lifelessly like a rag doll tossed away by a child that got bored of it. His small body ended up next to Amaimon. Amaimon, self conscious now, was trying to catch his breath while a burning sensation was eating away his injured shoulder. Yukio extended his arms to lift Mephisto up, but Amaimon wrapped his arm around the kid quickly, bringing him closer to his chest. His teary eyes looked up at Yukio. "What did you do to my brother?" his voice was not firm or stable because he was crying... it was so rare seeing someone like Amaimon in such a state. Rin approached them too. Why did Mephisto want to help him? Was he aware of their fraternal bond? Why did he do that? And more importantly, how did he do that... Both Yukio and Rin, noticed the blood pool on the floor "Aahhh... I should bring some bandages and maybe a pliers for the bullet... I'll be right back!" Yukio stood up and started running, while being confused about the whole situation. Rin knelt beside the injured demon and without letting go of his demon sword he locked his eyes with Amaimon's. "Why are you here" Rin wasn't even asking, he was demanding an answer. Amaimon held his brother even closer to him "If your only family had gotten lost, you would do the very same thing" Rin couldn't understand Amaimon's admiration and fondness for Mephisto. Well, of course they were close, but he had seven more brothers, so, what makes Mephisto so special? On the other hand, he was right. Rin wouldn't be able to handle Yukio's disappearance. His one and only brother ment the whole world to him. Well, that must be what Mephisto was to Amaimon; His whole world...

Rin's eyes softened a bit. He was now sure that Amaimon ment no harm. In his condition though, he wouldn't be able to harm anyone even if he wanted to. Rin scratched the back of his head in embarrassment. "Well, aaahh... I guess you could stay here... until you get better, that is!" the half demon looked elsewhere, still embarrassed. Amaimon kissed Mephisto's head, who was still in his arms, unconscious. "Thank you" he closed his eyes and said nothing more. Rin thought about all those things that had changed his life in these few hours. First, Mephisto turns into a small child with a whole different personality than his adult self, after that, he's in charge of taking care of him for God knows how many days or months and finally, Amaimon...

Yukio returned with new bandages and the first aid kit. "Well, let's see... First of all, I have to pull the purified bullet out of his shoulder..." the young exorcist turned Amaimon over, removing Mephisto from his grip and placing him on Rin's lap once again. Behind the glasses, his eyes fell on a small, red thing on the floor. Yukio wore a white glove and took the small object in his hand. He looked closely at it and fixed the glasses on his nose. "This is the bullet I used! It should be still in his shoulder! How is that even possible?" Did his body reject the bullet itself? No, it must be something el-No way... the young doctor's eyes fell on the green-eyed child on his brother's lap. "It was all his work!" Rin looked at his 'little one' too. "So what do you say, dude? Did he reveal his true power or something?" Yukio looked Rin in the eye "That, my brother, was just a hint of his true power. It's a Gehenna royal demon we're talking about. He has power beyond imagination! You don't even know who you're dealing with! We, exorcists, are no match for him. He'll burn us to the ground with a single strike! That's why the Vatican has to keep him on its side. He's either the greatest ally of humankind or its most dreadful destroyer. And all these powers and potential exist in this child, the one that you treat like a normal person, well Rin, I hate it say it but he's not normal! Not at all!" Yukio was now yelling. It was obvious he was under a lot of pressure.

Rin understood that his brother was trying to protect him, but he was already feeling so attached to Mephisto that he couldn't see the whole truth. He lowered his head while Yukio was tending on Amaimon's injury. "First of all, you were the one who agreed on taking care of him, and secondly, I figured out that he's not that bad... I mean, look, what separates a human child from a demon child? It's only natural not to know how to control his power. I promise, he means no harm! Just let me help him... please, Yukio. Don't you see? He's not opposed to Satan for no reason; His own father rejected him. He was all alone, like you and me. At least, we had the old man..." Yukio finished his work on Amaimon's shoulder, helping the green-haired male sit up. Amaimon hissed in pain. The young doctor exhaled.

"I'm not saying it wasn't my idea, I'm just trying to protect you. Don't be so opened up, Rin." Rin lowered his head once more, like a spoiled child that his parents wouldn't buy him a toy he just saw. Yukio smiled at his brother's childish behavior. "Oooh, Good God! Okay, fine. I promise, I'll help you, Rin. Isn't that enough?" Rin's light blue eyes lit up "I knew you weren't a jerk, bro!" Yukio stood up "Okay, let's finish with all of this. Help me lift Amaimon up, Rin" the half demon teenager stood up as well "Kay, but first I have to put Mephisto to sleep. I'll be right back!" Rin left the room and walked into his and his brother's dorm room. Mephisto was still unconscious after the show he put on. Rin lay his small body under the blankets of his own bed. Mephisto was back to normal; No blue hair, or purple veins, or blood... Unfortunately, he was back to being sick. Rin remembered that, and checked his temperature putting his hand on his warm forehead. "Not good" he monologued. The child exhaled because of his half brother's touch; He was feeling good with Rin's cool hand on his hot forehead. He opened his feverish green eyes, waking up after a long time. "Rin... help... me..." Rin brought his face closer to Mephisto's while caressing his cheek. "Shhh... it's okay. Everything's gonna be alright, pal! I promise... Sleep for a while and I'll be back" he dampened a piece of cloth and put it on Mephisto's forehead. He then stood up and left the room quickly. He then went back to assist their other 'guest'. Yukio put his arm around Amaimon's waist and so did Rin. The boys helped the demon walk to their dorm room. "Why are we doing this? You didn't shoot him in the knees or something, did you dude?" Rin asked, trying to synchronize his pace with Amaimon's. "It's not that simple, Rin. Once elements of purified water enter a demon's body they start dissolve blood's ferrum and other elements that are important for the immune system and that makes the demon feel weak and drowsy and it will finally lead him to death." Both Rin and Amaimon turned to face him in shock. He continued while a drop of sweat rolled down his forehead "Well, thanks to Sir Pheles' interference you just avoided the last state!"

They made their way in the dorm room. Rin felt a sting in his heart seeing his little one in such a state. "Let's put them in the same bed so Sir Pheles won't feel cold anymore, shall we?" offered Yukio. Rin nodded without taking his eyes from the child, like the perfect guardian. Amaimon fell lifelessly in the bed, beside his once-older-now-younger brother. Mephisto was in the in-side of the bed so he would fell off. "How are you feelin'?" asked Rin a bit sympathetically. Amaimon turned to face him, examining him with his tired, half closed eyes. "I feel sleepy... tired..." Yukio came in view "would you like something to eat or drink?" he was trying to be more friendly, feeling sorry for what he did to him. He was only trying to protect Rin, after all. "No... Aniue needs water..." the twins looked at each other. "How do you know?" Amaimon turned to look at Mephisto's sleeping form "I feel it... I know what's going through his mind..." Yukio fixed his glasses on his nose. "Alright, I'll be right back" said and closed the door behind him. Rin knelt beside the bed impatiently. "What else do you sense?" Amaimon turned to face him. A mischievous grin appeared on his tired face. "Why do you care so much, anyway?" Rin was taken aback. He had to think about it for a while. He couldn't believe he was about to unbosom himself to one of his worst enemies. He gulped without letting Amaimon notice. "I know Mephisto is not who he want the rest of us to think he is." Amaimon closed his eyes, unable to cover himself with the blanket. "Well, don't underestimate him..." he was acting like he knew something more. Well, of course he knew since he was his brother but Rin was feeling that he was hiding something big... Amaimon sensed Rin's dissatisfaction that was caused by his laconic answer. He then decided that he would tell him something juicy (and of course rated as a top secret) as a thanks for letting him stay in their dorm. Of course that piece of information would damage Mephisto's cover and schedule but Amaimon was determined to play that card anyway. Deep down he knew that neither Rin nor Yukio would use this information to sabotage Mephisto. He grabbed Rin's hand and held it in his own.

"What if I told you that Mephisto is a hybrid?"

Rin opened his eyes widely. "What do you mean a hybrid? Something like me?" he wasn't even sure if he wanted to here Amaimon's answer. Amaimon's dull eyes lit up. "Nah... No, brother... Even more powerful... You stand no chance against him..." "Wh-wh-wha' do you mean by that?" Rin was so confused right now. Man! Mephisto? A hybrid? But if he wasn't the son of a demon and a human... then, whose son was he?... Could it be...

"Yes. My brother is the unholy offspring of the demon Lord and an angel"
