Chapter 1: The blue haired demon

The blood felt good. It tasted good. "Heh. These humans are weak. So fragile." Said a certain blue-eyed, blue haired demon. He smirked as blood was all over him. There was only a couple of Exorcists left. The rest left in fear. "Come on brother, lets go before father gets mad at us for being late." A green haired Earth King was standing next to the demon. "Wait, there's someone over there.." He pointed to a girl, about 5'2. "Hmm? Oh.. She's playing with a demon..." The green hair demon walked over to her. The blue hair one teleported in front of her. "Hello there, human." He said, kneeling down for her height. She looked up and yipped. "Oh my GOD! A demon!" She screamed and ran. The demons stopped her from running away. The screams brought the exwires' attention and they pointed guns at the two of them.

"I'm Rin Okumura, prince of Gehenna. This is my brother, older brother, Amaimon." He smirks as Amaimon waves at her. "I'm Grace Berlitz." She said. "Why were you playing with the demons? Aren't you afraid of them? Like you are with us?" Rin questioned her. "Nope. I ain't scared of you, Rin Okumura. And your brother either." Rin was starting to like the blonde girl. He licked his lips. "She's gonna be my first female victim." He thought to himself. Amaimon was standing next to him. "Well brother should we spare her?" Rin looked at his older brother. "OF COURSE! Why wouldn't we?! She didn't even try to kill us. Despite her being an exorcist, we can give her a damn chance." He growls at him. Amaimon seemed to understand. "Well you're right young brother." He smiled.

Rin turned to face Grace and pointed right at her with his finger and placed a claw on her cheek. "You know, I already like you. You fit for a queen. Someday, I want to marry you and you can be my Queen of Gehenna." He whispered into her ear. Amaimon seemed to heard what Rin said to her and smirks. "We could use a queen back in Gehenna..." He had thought to himself and grins at the thought of it. "YOU!" Rin pointed at Grace. "You're gonna be my princess~ I've chosen you to be my princess." He slightly smiled and bares his fangs at the exwires and exorcists. "M-me?! WHY ME?" She shouted.

"You're special. Something about you I /really/ like about you, Gracey." She blushed at her new nickname the demon had given to her. "These damned exorcists and exwires would never let me get into her dorm. Not even for a freaking second. I hate these damn rules. Maybe if I fake that I'm a hybrid then they might let me in." He thought about his plan and smirks. "Lets go back to Gehenna Rin! Father's waiting for us!" Amaimon shouted at Rin. Rin growls. "Fine!" With that they both left to Gehenna.

Chapter 2: The demon gets in the school.

It was about 2:00 PM at True Cross Academy. The breeze was cold and nice. The trees blew in the air. But what interrupted a very beautiful, calm, and peaceful day was an explosion caused by blue flames in the sky. An exorcist that was tall, had dark brown hair, and glasses stood up and froze from the explosion. He was teaching his class about a lesson. "Okumura-sensi You alright?!" Bon stood up from the desk and walked up to the window. Shima walked up behind him then Izumo, then Shiemi, lastly Grace. They all gasped when the figure popped up in the flames. He was on the ground, had fake demon scratch marks that looked very realistic, he turned into a human to make the exorcists and exwires know he was human. But he wasn't just human it looked like he was a demon hybrid! He used his human blood for him to be a hybrid again temporarily.

Shiemi ran from the building and went up to the blue hair'ed boy. Grace followed but she remembers, this is Rin Okumura; Prince of Gehenna. A Demon. Not a hybrid. Yukio went up to his twin brother but he doesn't remember him much. "... Take him in. We must treat his wounds and make sure he's awake." He informed. Shiemi nodded and Bon tried to pick him up but he couldn't. Rin stood up on his own but fakely struggled. "Owe.. oof.. What hap- HEY! You.." He pointed at Grace and went up to hug her. "Missed ya." The group expect Yukio all gasped. Rin chuckled and let her go. Grace looked up. "I knew you were faking it-" Her mouth got covered. "Aye.. She's just excited because, I get to be going in her dorm right?" He looked around with a confused look but he naturally growled at each person in the group. Expect Yukio he had a different reaction to him. "Yu-Yukio?! He's a teacher here huh? Whatever. At least he'll take me in. He doesn't know I'm a demon right?" He took a big gulp before looking at Grace then back at the students.

"Wh-What are you?!" Bon looked at Rin with fear as he saw a tail behind him. "I'm a demon hybrid." "SON OF A DEMON?!" Shima yelled out in fear. "Yea but I'm not gonna hurt you.." "How can we trust you?" Yukio finally spoke out. "...Because I'm your older twin brother! I can't hurt you, Yukio!" Yukio jumped. He had never expected Rin to remember him. "O-Okay. You can be in Miss Berlitz's dorm for now until we get a free one for you.." He smirked. "By the way, I'm Rin Okumura." He looked down. "Damn why did I give all of that information away?! But at least their buying it." He looked at Grace and smiled. "Looks like I'm staying with ya." The group left expect for Grace. "You plan this didn't you?!" She walked up to him. "Without a doubt, my sweet Gracey." His pupils glowed red for a split second before they went back to normal.

Chapter 3: A demon's girl.

After a couple of days, Rin was getting to be annoyed with being around exorcists. He despise them all. You know being a demon, the son of Satan and being in Gehenna throughout his life. He was raised to kill as many as he can. He didn't want to be friends with Any of them. He wasn't allow to kill or hurt his twin brother Yukio. He had already chosen a specific girl to be his girlfriend; Grace. It was about 10:00 PM. Grace was sleeping peacefully in her bed, Rin was sleeping next to her. He woke up. He smirks and gets off of the bed. "Gracey.." He whispered, trying to wake her up. "It's time to go back to my place. My dad's getting worried sick about me. He wants me to be home now." He whispered again. Grace woke up slowly. "No." She simply denied him. He growls and grabs her arm and summoned a gate with no problem. Then he jumps in with Grace, closing the gate behind them. Grace fainted. When she woke up an hour later she was on a bed. It was a queen sized one. Perfect for two people. The bed sheets were black, and the bed set was darkly colored.

Then something hit her nose, it made her sneezed. It was soft at the end. It was darkly colored. It was.. Rin's tail for God's sake! She gasped. "Where am I?" She looked around, it was cold and dark. Expect for under the blanket of course! "Welcome home my sweet girl." A voice from the darkness answered her. She looked around and saw it was Rin! He was in his true demonic form. Due to the demonic atmosphere. "R-Rin.." She shuddered. "Don't be afraid my love. We are home at last, away from those damned exorcists." "But they are my friends." "Not anymore." "If they find out that I'm with a demon they'll execute me!" "That's bul- Actually that's true. They could but I ain't gonna let that shit happen to you. If they even lay a hand on you, I'll kill them. Even if it means I die, dammit!" He softly yells out. Then he pulls her into a hug.

"Would you like to be my girlfriend?" He asked with an innocent look. It was too innocent for a demon. Damn him! He had a cute and handsome face. Despite him being a damned demon! She looked up at him. "... I... Yes... But what if-" She was stopped by a finger on her mouth. "No buts or what ifs. IF they find out, who freaking cares? I'll protect you. No matter what." He held her close to him, his tail wrapped around her leg like a vine.

He nuzzled his head onto her chest. "Rin.." She looked up at him. He puts his face up to her neck and move her head just a little to her right. Damn he was strong! He was 10x's stronger than her. After all he is a demon and have super strength. She felt his long, elf-like ears on the top of her jawline. He beings to kiss her neck and then sucked on it until it left a hickey. Now she's a demon's girl. The prince of Gehenna claimed her to be his. "Nobody can't have you. You're mine. And I don't share. I'll never share you with anyone. I don't give a damn what people would say about us." He said. He put her face up to her's.

"Rin... I.." She was stopped. "Yes, Gracey?" "Rinnie I love you.." She admitted it. His eyes widened but then he smiled, showing off his fangs. "I love you more, Gracey." He blushes at his new nickname that she had given him. She hugs him and kisses his cheek. "You call that a kiss? You humans can be pathetic but jeez Grace! Give me a real kiss." He joked. "But I never thought of it.." That made Rin smirked. "I'll show you a real kiss." Then after a moment Rin sat down on the bed and put Grace onto his lap.

Grace stared at him for a few moments. But then she felt cold lips pressed onto her's. They belonged to Rin. He gave her a soft kissed on the lips. She was surprised by that. She kissed him back the same way. She returned the kiss. He wraps his arms around her waist. "Tomorrow we can have some real fun if you want, and maybe start a family. Some day you'll be my bride." He smiled and nuzzles onto her. She smiled.

Rin yawns loudly. "Hey babe, I'm tired how about we rest and think about this tomorrow?" "Sure Rin.." She said softly. Rin smirks and got her off of his lap and lay on his back. She did the same. He cuddles up to her, his tail wrapping around her waist. Grace smiled. They both kissed each other for a good night kiss. Then they drifted off to sleep.

[The Next Day]

Rin woke up with a scared look. He couldn't find Grace. "Babe? Grace? Gracey?!" He calls out. "She went back to Assiah." Amaimon answered him. Rin growls and got dressed and goes up to a portal he had made to Assiah. "Grace I'll find you!" He said. "Good luck brother!" Amaimon yells out to him. "Thanks but I don't think I need it." He jumps in front of the campground of True Cross.

[In the classroom]

"Miss Berlitz. Why are you la-" Yukio stopped his question as he froze. "late? OOOOOOOOOOOOOOOOOOOOOO About that I was uh-" Yukio stopped her sentence with a glare. "Miss Berlitz, Why do you have a scarf on your neck? It is not cold. Please take it off." Grace had to listen to him, after all he was the teacher. She sighs. "Fine..." She took off the black scarf. Yukio gasps. "Grace, what in the hell is that? What or who did that to you?!" He pointed out her hickey that was noticeable on her neck. "Tha-" "You... You... Have a boyfriend?" Bon asked. "Yes..." "Wait that doesn't look like a human bite.. That's a demon's bite!" Shiemi pointed out. Yukio gasps. "YOU DATING A DEMON?!" He yells out. "Miss Berlitz you may be dismissed for today. You have alot to think about." "Shit... they knew..." She told herself as she ran out of the classroom and out of the building and bumps into Rin.

Rin grabs her arm before she could run any further. "Babe, why did you left?" "I had to.. I need to go to school today, they'll notice I'm gone.." "... Don't ever do that again! You had me worried sick now let's go home now!" "But Rin they found out about us!" "Who the hell cares?! They can't get you if you're in Gehenna now lets go!" He yells out at her and goes back to Gehenna by using the portal with her. "How did they find out? " Rin thought to himself.

Chapter 4: The new life in Gehenna.

"Grace, why did you ever go back in Assiah, you're Suppose to be here with me!" Rin yells out. "I know but-" "But nothing! I've already told you you're mine. YOU need to stay here in Gehenna so the Exorcists can never hurt you. I do not want you to die." "But a human can't be down here.." "Yea no that's not true, babe." He said while walking back to the palace.

[At True Cross]

"Where is she?" Yukio was searching for Grace. He couldn't find her. Then it dawned on him. "The demon must have taken her back to Gehenna with him." Yukio sighed and he sat down on the couch. "Damn, how can I let that one slip?" He facepalmed himself.

[Back in Gehenna]

"How did they find out she was with me? Dammit..." Rin thought to himself. He summoned some demons. "You need to protect her no matter what." He ordered to them. They nodded and just floated around Grace. "I don't need pro-" "Yes. You do now then, you stay by my side at ALL the time!" He told her. "But Rin-" "No buts babe. I love you and I want you to safe. I don't trust those Exorcists." "I love you too.." She then turns around and walked up to the bedroom.

Rin was now wearing a dark colored t-shirt and some jeans with dark colored shoes. "I know you don't like it here, but this is my home. Our new home I should say. You are now mine now. No one can have you." He pulled her close. "You should go change. If my dad come around here, then he'll say something due to your disgusting uniform." He took out a dark purple dress and gave it to her. "Here, wear this for now." She takes it and gets dressed. She came back with her hair in curls with a dark purple bow in her hair.

"You look so cute, baby~" He said while hugging her, his tail wrapping around her waist. Grace seems to sigh. "Can we ... visit Assiah every now and then?" "Well.. if we do we need to get in a disguise. The exorcists now know you're with me. I'm a demon. You need to stay here for now at least until they don't need to kill you." She nodded.

[Back in Assiah]

"If that demon is with Grace, should we kill him?" Bon asked Yukio. "No... We shouldn't." "Wait what?!" "I know that may seem wrong but we shouldn't take that away from Grace. If she loves a demon then let her. There's no reason to kill anyone." "But we have to... it's our job!" "I know, Bon but.. just leave them alone for now." "Fine." With that he left.

"Rin.. I hope you don't come up here, they're gonna get you and Grace if you even step close to this campground." Yukio hoped that Rin wouldn't come up here.

[Back in Gehenna]

"Rin I do love you." Grace said while sitting on the bed. Rin sat down next to her. "I love you more, but lets rest up, we gotta big day tomorrow." He said while laying back, taking his shoes and socks off. Grace lay down as well. He cuddled up to her close, his demon ears rubbing against her cheek. She nuzzled back and cuddles close to them. Then they slowly drifted off to sleep. "Yukio... if I do come back to Assiah please let the exorcists know to to kill me." He thought in his head.

The next day they woke up. Rin held Grace close to him. "I know you don't wanna live down here but why don't you and me come up to Assiah and go the the amusement park?" He asked her while he held her in his arms. "Sure Rin!" He smiled and lays back down. "Eh, I'm still tired how about we go later?" "Sure." She cuddles next to him and lays her head on his chest. He smiled and rubs her back gently. Then they drifted back to sleep.

[ Back in Assiah]

"Class!" Yukio said, bring the students' attention. "We are going to the amusement park close by here. To catch demons." He instructed. The class the cheered. "For now, lunch break!" He dismissed them all. "Why do I have a feeling Rin's gonna be here? I hope he isn't coming up for a visit." Yukio thought to himself as he went to the cafeteria.

"I hope Yukio won't see me up there with her.."

TIME SKIP

TWO YEARS LATER.

Chapter 5: The wedding. The new beginning of a new life.

Grace was in a pretty pink and purple dress with matching bows in her curly blonde hair. She sat on the grassy field of the grassy meadows filled with beautiful purple, red, sapphire blue, and pink flowers. It was sunset, Rin was dressed nicely. He looked at Grace and hid a black box behind his back. He called out Grace's name and as she turned around he kneel on one leg and looked deeply in Grace's eyes. "Grace I know that we only knew each other and been dating for two years, I want to be with you for the rest of your life. I want you to be my bride. Will you marry me Grace?" He opened the box and showed a pretty golden ring with rubies, sapphires, emeralds, and diamonds. Grace's eyes watered in joy and as she smiled widely to her boyfriend and now soon to be husband. "Yes I will marry you." She said in a happy tone.

Rin smiled so big that all of his teeth showed. Including his sharp fangs. He put the beautiful ring on her right ring finger. The wedding was in two weeks they planned it all out a week later. Two weeks had passed and the wedding is here. Grace walked down the aisle. She wore a beautiful wedding dress with a vial in her hair which was curled. She had some pretty make up on and held a beautiful bouquet of flowers. After a while the speeches were done. The priest said "You may now kiss the bride." Rin leaned down to Grace's face and kissed her on the lips and she returns the kiss.

After the reception was over Grace and Rin went home. They both laid down after they went into their pajamas. Rin looked closely in Grace's eyes. "I want to have children Grace.. maybe 3 or 4... I wanna try for one... maybe twins?" He asked her while getting close to her face. Grace smiled and nodded. "I could use some more company around here.." She agrees with him. He kisses her passionately and the kiss deepens. Rin broke the kiss with Grace for air. He then smirks and starts to kiss her neck. He positioned himself to be on top of her.
