Chapter Four

Darkness will forever roam in my heart

Trapped by these chains

There seems to be no escape

Yukio rested his forehead on his cool wooden desk as he sighed. Grading papers for his exwire students and doing homework for his regular college classes was really time consuming, but a hardworking exorcist such as him couldn't complain. He had to keep up on his work and had to make sure to not fall behind on his duties as an exorcist.

Lifting up his head, he spotted the top of a picture frame that was nearly hidden behind a mountain of papers. He reached for the picture frame and pulled it out of its hiding place. In closer inspection, he found that it was a picture of him and his family a few days before he and Rin started eighth grade. Yukio was smiling at the camera with his father's arm placed on his shoulder. But something in the picture made his stomach turn and his heart tighten with regret. His father, who was grinning at the camera, had Rin, who was on the other side of their father, in a headlock. Though Rin appeared to be struggling to get loose with a look of annoyance on his face, there was a soft expression in his ice-blue eyes that clearly stated he didn't mind the position he was in.

It's been two years since he got a call from their father about his older twin brother's disappearance. There was only one body in that house fire, which was identified as Rin's roommate Jun Anderson leading police to believe that Rin was a suspect. It made Yukio and Fujimoto worry. I doubt it was really his fault – thought Yukio, caressing his brother's face in the picture as he recalled the last thing he said to his brother.

"I wish you were dead," he had said and the very answer Rin had given had torn his heart into pieces. His brother clearly told him out loud that he wished the same thing. Why Yukio had said those things he had no idea, but he regretted them with every fiber of his being. He wanted to tell Rin how sorry he really was, but now he couldn't.

Yukio then jumped up out of surprise, nearly dropping the picture in his hand, when he heard the ringer to his cell phone. Placing the picture down, he answered the call and placed the phone to his ears. "Yes, this is Okumura."

After listening to the other person on the other side, Yukio nodded his head as he said, "Yes, alright, I'll be there."

….

Feeling something gently poking him on his cheek and a small weight on his stomach, Rin opened one of his eyes having ice-blue meet with chocolate-brown. The owner of these eyes smiled slightly as she sat back on his stomach, applying her full weight as she held up Rin's cell phone, it was vibrating announcing that someone was calling.

Groaning, the half-demon pushed himself up into a sitting position and took his cell from the small child's hands. He looked at the number that read unknown caller. There was only one person who called under the identity of an unknown caller. Pressing the green button, he placed the phone to his ear and answered with a deadpanned, "What?"

"Don't 'what' me, Okumura!" yelled Ryuu's voice on the other end. "I tried calling you for about three whole hours and no answer! What's up with that?"

"I didn't feel like answering, but now I have to because Risa handed me the phone," Rin said, trying to hold in a yawn which didn't work out that well. He could literally hear Ryuu cracking his knuckles and loading his guns. That guy was a pain in the ass, but he was also a useful comrade to have by his side.

Letting a playful smile spread upon his lips, Rin spoke in a teasing tone as he ruffled up Risa's pigtailed golden hair. "I'm just playing, man, anyways what's up?"

"The evacuation of the city is nearly complete and the boss said it's almost time for us to make our stand," said Kai into the phone with his cheery-hyper voice, but even so Rin could still hear Ryuu getting ready to kill him and muttering things of what he would do once he got his hands on Rin, which had Rin make a mental note to stay out of the full-fledged demons reach.

Peeking over the edge of the roof of the building he was taking his nap on, Rin noticed that the streets were empty besides the few exorcists that were patrolling the area. "So… the target is?" he asked with a slight interest which caused Kai to yell in his ear.

"OMG, Rin-nii, you actually seem like you care!"

In the background, Ryuu scoffed as he said, "He's only interested in the kill not the details of the mission, cat boy, remember that." That comment caused Rin to chuckle as he made his own retort. "Gee, thanks, gun fanatic, I just love it when people say I'm bloodthirsty."

"Anyways, the target is a demon by the name of Shiroto," continued Kai, getting serious for once which was rare for him since he was always so hyper, probably due to all the sugar he eats. It wasn't much of a surprise for Kai to act like a child when he himself was no older than Risa who was only six. "The boss says he's a vital point in our plan."

Before anything else could be said Rin ended the call, he'd probably get scolded by Ryuu later for it, and sighed. Turning his attention to the small demon child sitting on his lap, he gave her a small smile. "You ready, Risa?" He knew the child couldn't talk; she refused to talk to anyone because her voice was like a sonic boom. But still Rin and the others in his group asked her questions or talked to her to make her feel normal.

Risa nodded as she smiled before wrapping her small, thin arms around his neck. Tucking one of his arms under her to hold her weight while in the other he held the hilt of his sword which was strapped to his belt at his side, Rin stood before leaping over the edge of the building. His black boot covered feet touched the cement without feeling any impact of the gravity.

There was no one around which was a good thing. He didn't feel like fighting against any humans. But there was a thick mist starting to fill the streets, miasma. Placing Risa down, Rin took off his leather jacket with quick pace and wrapped it around her to cover her face. "Make sure to be careful not to breathe it in, okay, Risa?"

Risa nodded her in understanding; she was very sensitive to a demons miasma.

Taking hold of her hand, Rin made his way down the street, keeping a tight grip on his sheathed sword the Kurikara. He would've left it behind for the mission, since he grew accustomed to using martial arts and his guns in battle, but Boss told him to take his sword saying that he would need it. Rin hated to listen to the demon, but he had no choice. It was either live as the demon's secret weapon or witness more people he cared about die. Even so he brought his favorite gun that Hideaki got him two years ago, hidden under his sleeveless shirt tucked in the back of his jeans.

Rin was about to turn the corner when he heard a yell from behind him. Hoping it wasn't a human, since he was ordered to kill anyone who saw him, Rin glanced over his shoulder, only to mentally face palm himself. "Just my luck," he groaned as he watched the two exorcists run up to him. "Anything I can help you two gentlemen with?"

"This area is off limits to civilians due to a poison gas leak," said the taller exorcist, who for some reason reminded Rin of his father Fujimoto with those weird glasses on his face and grey hair. "You must leave this area immediately."

Rin glanced down at Risa before walking away, letting go of the young demon child's hand. "I leave this to you," he said, his back facing away from her and the exorcists as he plugged his ears. The exorcists were about to call out to him again, but before they could the girl opened her mouth and suddenly a high-pitched screech shook the earth having their eardrums bleed as they screamed in agony, falling to their knees.

Glancing over his shoulder to the bloody scene behind him, Rin smirked at their pained filled expressions. Blood pooled from their ears and eyes, even from their mouths and nose as they lay there on the ground unmoving. "Risa, that's enough," he called to the child, and just like that she closed her lips together and the shock wave of sound was gone. This kid is defiantly a force to reckon with – he thought still with a smirk on his face.

Risa turned and held out her hand toward Rin to take and when he did her beautiful smile returned to her pretty little face.

….

Kai sighed as he just sat there on the edge of the roof of the building where he and Ryuu set up base, watching all the humans down below. "I'm bored! When do think you we'll be able to attack?" he whined having his cute little cat ears on his head flatten in his hair and his tail flick out behind him in boredom. He hated waiting, all he wanted to do was to have some fun even if the fun involved killing his half brethren down below.

"Would you shut up or I'll shoot you," glared Ryuu as he stood up and made his way over to where Kai was seated, the guns strapped to his waist looking even more dangerous than ever with the blood stains on them from their previous mission. Apparently Ryuu didn't have time to clean them off, noted the half cat demon with a frown. He hated guns, he liked bombs and explosives better.

Ryuu stopped near the edge of the roof, placing his hands on his hips as he stared at the human's below with disgust. He hated humans more than Kai did, though Kai's hatred was more like feeling something close to unwanted. His father was human while his mother was a demon who loved each other, but others couldn't see their love that way and hated Kai and his family.

"What's wrong?"

Ryuu barely spared Kai a glance before looking back at the humans below. Following his gaze, Kai noticed one human in particular, the one human Boss told them to look out for, Okumura Yukio. "I wonder if Rin runs into his little brother would he be able to kill him."

"I doubt that," said Kai, pulling a piece of foiled wrapped chocolate from his pocket. "Even though Rin-nii acts all bloodthirsty and mysterious or even like he hates the world, there's no way he could kill his own flesh and blood. He's not like us, Ryuu. He still has a heart, though he hates to admit it."

Ryuu then decided to look at him then before turning his back on Kai and the humans below. "Let's just hope he doesn't mess up."

….

Glancing up, Yukio couldn't help but feel that someone was watching him. He didn't see anything; the city should've been evacuated. Nothing should be left in the city limits besides the exorcists and the demon they were suppose to kill. But even so Yukio couldn't help but feel there was something else out there, waiting and biding its time.

"Is something wrong, Okumura?"

Jolting slightly in surprise, Yukio stared into the eyes of his companion Arata, who appeared to be worried. The man just met Yukio starting today, though he knew his father, the exorcist appeared to worry about him. It was probably because Father told him to keep a good eye on Yukio and help him when he needed it.

Yukio hated having others look after him; it reminded him of his older twin brother Rin. His big brother protected him from anything and everything, even the demons that he couldn't see. Even though Rin couldn't see the monsters when they were kids, Yukio always ran to his side for protection and then the demons would leave him alone. Those monsters were afraid of Rin, though Yukio had no idea why.

In a way he still didn't.

But still he hated being protected by others now; he was stronger than he was before. Maybe not as strong as his brother or Father, but still he wasn't a child that needed an adult watching over him anymore.

Smiling, Yukio placed his hand on his Arata's shoulder to try and reassure him. "I'm fine, just a little nervous since this is a really big mission. I haven't had one of those for a long time."

"Don't worry about that, Okumura. I'm sure everything will be fine. You are Shiro's son, after all."

Yukio nodded his thanks before looking up at the building they stood in front of, the building that hid the demon's nest. He got a report that a high class demon was hiding in this building, but he never thought the demon could be this strong. He wasn't even inside the building and still he could feel its power. It was deadly and suffocating. Yukio found it a surprise that he could even breathe or stand on his own two feet.

Just what kind of demon are we hunting – he thought, glaring at a shadow of some kind that walked passed one of the windows from within the building. He pushed that thought aside and started to assemble his team, getting ready for the hunt.

….

Crouching down low the ground, Rin let out a small breath of air as he leaned in closer to the wall. The demon was just around the corner and by the sound of things he was feeding. His mission was to take the beast into custody in whatever condition he could, but it still had to be alive. That wasn't a problem, but Rin couldn't help but feel his demon blood boil, hungering to spill blood.

Reaching for his gun, he slowly stood to his feet. Calm down, if I'm too excited I might end up doing something that I'm not suppose to… like killing him. He took in deep breaths and then let them out slowly as he tightened his grip on the trigger of his gun, holding it so it was level with his shoulder as if he was an expert. And he was.

"Who's there?" growled the voice of the demon. "Come out and I might just let you live."

The demons voice was deep and it sounded as if there were more than one person talking at the same time, Rin noted. But the thought never stayed processed in his mind for long. He pushed himself away from the wall, glancing down at Risa as he gave her a signal with his eyes to stay put, before he turned the corner down the hall.

What he was met with was a grand sight that had his demon blood scream out in bliss. Blood was all over the walls and floors even the ceiling. The demon he was hunting,in the form of a human, was crouched over the body of a human woman and her child, dead from the look of it, his mouth and sharp teeth covered in their blood.

The demon glared at Rin with his crimson eyes. "A half-breed?" he questioned before his eyes suddenly widened with realization. "No… from the smell of things you're not just a half-breed, but the great king's favorite spawn. Why is the son of Lord Satan doing here hunting me?"

"Sorry, but I'm not that bastards son," snarled Rin, aiming his gun at the demon's heart. "I work for a greater and much more interesting cause. Satan is just an obstacle that's in the way."

Smirking, the demon placed his clawed hands on the floor and threw his head back as he started to howl. The howl was ear piercing, almost like Risa's sonic boom. Suddenly Rin noticed something come flying his way. Rin didn't really see what it was, but what ever it was it sent him flying sideways, his head smashing through the windows and almost his body. Before his whole body went flying out the window, Rin caught himself, cutting his hands on glass.

Glaring over his shoulder at the demon with blood pooling from a cut above his eye, Rin bared his fangs as he said, "You asshole, that fucking hurt!" But his rage was short lived when he noticed that the demon had some kind of tail. It wasn't all that surprising that a demon had a tail, all of them did, even Rin. But this guy's tail was like that of a lizard with spikes… no, bones sticking out of it at the sides.

Just what the hell is this guy? – thought Rin as he pushed himself up away from the window. He glanced over at Risa and then back at the demon. He couldn't let her fight this guy. Even with her voice being a sonic boom, this guy would kill her before she could even part her lips for an attack.

The demon sneered at Rin for a brief moment before he leapt up, breaking the ceiling above him as if it was nothing, and disappeared as he laughed.

Cursing, Rin ran after him. "Risa, I want you to get out of here and meet up with Kai and Ryuu!"

….

Risa watched as Rin leapt through the hole in the ceiling after the lizard demon. She wanted to go with him, but she knew Rin was right. She stood no chance against that demon. He'd kill her before she could even use her sonic boom attack, and then what? Rin would be punished by the boss for her death.

She hated to see Rin in pain, but Rin didn't seem to mind. He was tortured day in and day out, not seeming to care if he lived or died. But Risa knew different. She had the power to read others heart, almost like the boss, though he fed off the dark emotions in one's heart. She could feel that Rin was suffering and that he regretted being alive.

When ever she read these emotions in his heart, it would always pinpointed to a human – most likely the same human that Rin called out to in his sleep… the human by the name Jun.

Closing her eyes, Risa clasped her hands together. "Please be careful, Rin," she said in her mind, sending the thought to Rin knowing he would hear her.

….

Cursing, Rin flipped out of the way of the lizard tail as he fired another round of holy bullets. No matter what he did, it didn't seem to phase the lizard-like demon, not even the holy ammo that he got from Amber. Was this guy even a demon? But the thought never had much time to process in Rin's mind when he was suddenly grabbed around the neck and slammed face first into the floor.

Clenching his teeth together, Rin reached for the hilt of his sword. If holy water and bullets aren't going to work, then there's only one thing left. But before his hand could even touch it, the demon grabbed him by the wrist, digging his claws into Rin's pale skin, drawing blood.

"Do you really think I'll let you unleash you're true power?" smirked the demon.

Rin glanced at his sword before glaring at the demon in front of him. Even without his sword he could unleash his flames, but they weren't as strong. If he did use them now all he would probably succeed in was giving the demon a suntan or at the very least burn him due to the demon's tough skin. Shit, why does stuff like this always have to be difficult?

Closing his eyes, Rin was getting ready to summon his flames, but then he heard something… it sounded like a gun being fired. Ryuu? No, the way Ryuu fired his guns sounded different than that. Opening his eyes, Rin noticed that the demon was glaring at something from behind Rin.

Out of curiosity, he followed the demon's gaze and what he saw caused his heart to suddenly stop and his eyes to widen in shock. Time seemed to have stopped all together. Standing just down the hall with a small handful of exorcists was his baby twin brother, Yukio, aiming his gun at the demon that held Rin down. It was obvious that he fired off the rounds just then due to the smoke seeping out of the barrel.

Rin just couldn't believe his eyes.

Yukio was right there, right before his very eyes after so many years. He didn't look like the crybaby that he always protected as a child and he certainly didn't look like the asshole that he was back then before he left to True Cross. He appeared stronger and held himself in high praise.

He was different and yet he was the same.

He was his baby brother.

The End
