Bound by Fire Prologue

Eight Years Earlier

"Are we close yet, Mom?" The younger twin asked, as he clung to his older brother.

His midnight blue hair cut short and his bright blue eyes watching him, as his older brother's mocha brown eyes looked down at him and his brunette hair fell over his eyes.

"We're almost there Aleka, be patient." Rin spoke, as he gave them a smile.

Walking behind him and in pace with one another his twin boys were strong and healthy sixteen year olds. Something that had been a big issue not long after they were born. It was the second week, after they held Isabella's funeral, that the both of them were getting weaker. Apparently their bodies had been developed to live in the Gehenna atmosphere and not Assiah's. Something that was jeopardizing their health and could lead to them both dying, and that was when Rin had made on of the biggest decisions in his life. He left for Gehenna to save the twins, and left behind everything he had in Assiah.

"Rin, stop and think about this." Bon spoke, as he grabbed the younger's arm. "If you go to Gehenna, Satan will-"

"Bon, I have no choice anymore." Rin interrupted, as he jerked his arm out of the older's grip and gave him a serious look. "Kaden and Aleka are all I have left. It was my fault, my lack of controlling my emotions that killed Isabella; but this I can control. If I take them to Gehenna I can save them. Then they won't die like Isabella did. Besides, without them I have nothing."

Before the younger could even turn around, the brunette n' blonde grabbed his cheeks and kissed him full on the mouth. A small gasp leaving the half-demon, before fell into the kiss and let the older have his way with him. The moment only lasting a few seconds, before the teen pulled away and Bon looked his straight in the eyes.

"You have more than Kaden and Aleka, you have me Rin." Bon spoke, as he brushed his thumb against the younger's cheek. "I realized my mistake of letting you go a few weeks ago, and this time I can't let you disappear. We'll find a way to save them, Rin. We'll keep them alive, just don't leave. Who knows if you'll even come back."

"That's just the thing, Bon. I have to leave. I love you, I've always loved you. Even when I had Nekoyoma I loved you, but right now the twins are more important. They're our children and right now I have to do everything to make sure they survive. You understand, don't you?"

In the moments after a wave of silence fell over them and Bon pulled him close to his chest. The younger accepting the embrace and cuddling into his chest, as his tail wrapped around the older's waist and kept them close. His blank's scent wrapping around him, as he smiled and leaned into him. Weight the older took with no problem at all, as he gently kissed the younger's head and tightened his grip around him.

"Promise me. Promise me you'll come back in one piece." Bon pleaded, as he buried has face into the younger's midnight blue locks.

"I will." Rin spoke.

"Then I'll be right here waiting for you." The brunette n' blonde spoke, as he reluctantly let go of the younger and held him at arms length. "I'll be here waiting for however long it takes for you to get back. So come back home soon."

"I will."

From then on out the journey had been hard. He had packed up everything he needed, the Kurikara included, and took the twins to Gehenna with Amaimon to watch after them. Even though, as weird as it sounded, the Earth King had been a big help. He helped protect the twins through their younger years and when they got around the age of six or seven, he started teaching them how to fight and protect themselves. Aleka the one how took to protecting and Kaden the one to fight. Which Rin didn't expect much less from the twins. As they grew up Kaden became the taller one of the two and never left Aleka's side. He was always their protecting him in his early years, till Amaimon taught him how to fight. Although the older was practically mute and rarely talked, he could get a point across fast to any demon that tried to harm the younger twin. All the while Aleka learned simple enchantments and learned how to protect others, while Kaden protected him.

This lifestyle continued all the while Amaimon taught him how to control his flames gradually over the eight years they were stuck with him in Gehenna's fast time cycle, but with one price of course. Just before Rin and the twins left for Gehenna not even a few days ago, Amaimon snapped the Kurikara in two. Yes it was supposed to be his 'demonic heart', but it had long since been. The moment he started training, was the moment the Kurikara became nothing but a weapon. Now he had full control of his flames and didn't need a sword and sheath to keep them in control. Sure he still had a professionally crafted demonic sword strapped to his back, but it was nothing more than a sword. A sword he could pull out and swing around to protect himself and one he could light on fire with his flames and use as an even deadlier weapon.

Yet, after eight years in Gehenna, everything was perfect. The twins were as healthy as they could be, minus Aleka's asthma he had on occasion, and he had full control of his powers. All that was missing in his life was one thing.

"Is this it, Mom?" Aleka asked, as he pointed to the huge gates and the sign that read 'True Cross Academy'.

"Yes, this is it; but we got a little more to go before we reach home." Rin spoke, as Aleka huffed and Kaden messed up his hair with his free hand.

The younger twin softly laughing and leaning against his brother, as Rin lead them through the gates and through campus. A number of students watching them as they moved to their next class, as Aleka looked around curiously and watched the teens the same age as them rush around. Kaden keeping the younger close and glaring at any guy that looked his brother over and let out a soft growl at one teen in particular who whistled. An act Rin decided to let slide, for the only fact that he knew Kaden could control his anger, as he turned down the familiar path and stopped at the start of the bridge. His sons stopping just behind him and Aleka giving him an odd look, before he followed the male's gaze.

Standing in the exact location as eight years ago was the abandoned dorms. The whole building redone from top to bottom, as the half-demon stared at the building and didn't even notice the front door open. A voice calling his name catching his attention, as the male quickly averted his gaze away from the building and his eyes fell on the figure standing in the doorway in pure shock.

Still standing at six foot and decked out in an exorcist uniform was none other than Bon. His hair still it's brunette n' blonde color and still swept back with a bit of hair gel, as the younger felt his chest contract and hesitantly took a step forward.

"Bon, I'm-"

The teen couldn't even get through half of the sentence, before his blank bolted out of the doorway and ran over to him. The older male suddenly wrapping his arms around him and holding him close, as he buried his face into the younger's neck and let out a shaky breath. Both Aleka and Kaden staring at their father in both surprise and confusion, as Rin hugged him just as tightly back and breathed in his scent. A soft sob escaping him, before he was softly sobbing into the older's chest and Bon was holding him tightly against him.

"I-I'm finally home." Rin managed to speak between sobs, as Bon held him tightly against him.

"And I'm glad you came back in one piece." Bon spoke, as he gently released the younger and gently cupped his cheeks. "I've missed you."

"I-I've missed you, too." The young softly spoke, before the older pulled him into a soft kiss.

"Mom, you said I wasn't allowed to do that with Kaden." Aleka complained, as Bon suddenly pulled away from the kiss and looked at the younger twin in complete shock and confusion.

"Surprise." Rin hesitantly spoke, as he gave him an innocent look.

"I'm guessing Aleka looks like you and Kaden looks like me." Bon spoke, as the younger nodded. "And Aleka just said what, exactly?"

"It's a long story." Rin spoke, as he turned toward the twins and gave them a smile. "Boys, this is your father."

Almost instantly Aleka's face turned bright red. The teen immediately burying his face into Kaden's chest, as the older twin gently pat him on the head and Bon sighed.

"You, Mr. owe me an explanation for why you've been gone for eight years." Bon spoke, as Rin smiled and gave him a smirk.

"That we can discuss in our room." Rin smirked, as Bon returned the look and swept the younger off his feet.

"Kaden, Aleka, make yourselves at home. Your mother and me will be up in our room. Don't come in if the doors locked."

Without another word, the brunette n' blonde carried the younger off toward their home. Leaving the two twins all by themselves in front of the house.

"I'm confused, why would they lock the door if they're just talking?" Aleka asked, as Kaden looked down at the younger and gently messed up his hair.

"You have a lot to learn." Kaden spoke, as he walked past the younger and headed for the door.

"Wait! I'm confused!"
