The teen raising badass

Introduction: Um, this is my first time publishing a story at FanFic so please go easy on me. If there's any grammar mistake(s), please inform me. I'm not that good in it. Anyways, this is a crossover between Beelzebub and Ao no Exorcist. I was inspired to write this story by this one picture I saw with Oga and Rin looking all bad ass. Both Ao no Exorcist and Beelzebub are my favorite anime/manga. So here you go, hope you like my first story. Ugh..

Disclaimer: Ao no Exorcist belongs to Kazue Katou while Beelzebub belongs to Tamura Ryuuhei. Even though I really wish to own Okumura Rin and Oga Tatsumi... Just imagine if I had them...My god..-drools-

The 'Child' Raising Badass

"…and stay out!" a hoarse scream can be heard after that gruesome battle. The victims of the rampaging ogre was badly beaten and definitely not in a good condition. They looked like as if they was just got stomped by some humongous beast. That aside, the brunette walked away from the scene and doesn't even bother to take a second look at what he just done. To him, what matter was that he was satisfied that he got a good fight. It had been a week since he got himself into any good brawl. He thought of what to eat since he realized his stomach had been growling a bit louder than before. "I think I'll go and get myself some of that croissant." He suggested himself.

"Thanks, Granny!" He took a bite of the croissant he just bought. "Damn, it's tasty! Granny's shop never failed me." He took the normal route he usually uses whenever he's heading home. The brunette-haired teen only looked forward, oblivious towards his surroundings. Suddenly, his eye caught a silhouette of something floating on the river. Curious by the vision, he walked towards the river to assure his anxiety. "What the hell?" With an awkward look, he muttered to himself. There was a blue-haired kid drifting unconsciously on the river. Oga just stared at it with a blank expression as the kid gets carried away by the flow of water. "Not my problem. See yea, kiddo" the brunette strutted away since he thought it was better not be involve in an event like this. Why should I care?

"Thanks for saving me." The blue-haired kid coughed a bit as Oga gave him a discomfited stare. "W-what is it?" The kid was dressed in a school uniform that the brunette doesn't seem to recognize. 'Black coat? Black pants? Red-black-white stripes tie?' Oga was trying to figure out which school uniform was that but no satisfying answer pops in his head.

"Hey kid, what were you doing in the middle of the river?" the brunette questioned.

"Like hell I know" Wow, talk about language "I was in class like usual and I got a bit sleepy so I tried to close my eyes for a while then this ugly old man came in out of nowhere and captured me and now I'm here at this unknown place."

"…."

"W-what?"

"…."

"WHAT? DON'T JUST STAY SILENT, DUMBASS!"

"You're not from here, aren't you?" Oga finally spoke up.

"Duh! Were you even listening to what I just said?"

'Wow, this is something' Oga's mind spoke. The day turned out to be rather weird and random than normal. "Sheesh...why did I even save you?" The taller teen scratched the back of his head while making a confused look. I hate it when curiosity consumes me. Oga was annoyed at himself and his habit of letting anxiety taking the lead. "So… you said there was this old man kidnapped you, right? Shouldn't he be with you since he's the one behind this happening and all…" The brunette asked the other teen, still confused at all this 'capturing' and 'randomly floating on the river near my neighborhood' stuff. "I don't know… maybe he ran off somewhere since he doesn't want to get punched in the face by me for bringing me here." The blue-haired teen retorted in a fierce tone. Definitely pissed off. "Hmm… since you don't actually come from here, that means you don't have any place to stay, right?" Wait, am I trying to offer him to stay at my home? "Obviously. I guess I'll have to find an empty house somewhere to take shelter. If there's any…" The kid grimaced a bit at his misfortune. Then Oga abruptly spoke up.

"Wanna stay at my place for a while?" Oh my god, since when I was this kind?

"…Can I?" That innocent look! MAKE IT STOP!

"Err..Yeah, sure. But only until this problem solve and you'll have to find that old guy. He's the one behind these scenes."

"Yeah..thanks for the offer by the way…" The blue haired kid's cheek turned pink a bit as he looked away.

'How did it ended up like this?' Oga pondered as he made his way towards his home along with the other teen. Oga took a glance at the kid beside him. Awkward..He's rather silent than before. "Oi, what happened to all your complaints just now? Your silence is creeping me out." The kid didn't give any respond. To be honest, the kid was damn noisy a moment ago. Non-stop ranting about how much he hated going to school, about his twin getting all the girls, about what's happening to him right now, about-

"Are we there yet?" Looking all exasperated, the kid abruptly asked.

"In a moment."

"…."

"We're here."

It was rather a normal 2 floor house. Different from what the blue-haired kid had anticipated which was an old house with a creepy and eerie surrounding –since he has this murderer face. Oga noticed that the kid has this mortified face and asked, "What's with the look?"

"Oh! It's nothing. It's…just that.." the kid frowned a bit after being startled with the sudden question.

"You suspected it to be an eerie house don't you?"

"Yea.."

"…."

Few seconds passed by and tension was building up around them. Oga sighed a bit and turned the door knob. He took off his shoe and-

"TATSUMI!"

"Oh shit, duck now kid!" Oga pulled the surprised kid's down, avoiding the oncoming falcon kick.

"What the fuck, sis?" It was Misaki. Oga Misaki. The brunette's older sister. A bit shocked at the sudden commotion, the blue-haired kid jaw dropped and he swore that was the most brutal sister he'd ever met in life. "Don't WTF with me! Why is there a beautiful hot woman in your room? Not to mention that she's wearing a Goth Loli kind of dress!" Misaki scowled at Oga, looking all angry and shocked at the same time. "What? What kind of crap are you talking about?" Oga raised one of his eyebrows and shoved his sister aside a bit since she was blocking the entrance. "Go check yourself, pea-brain." The older sister placed both of her hand at her waist and made an irritated face. Oga climbed the stairs and headed towards his room while the other kid was still at the door, amazed by Oga's sister's incredible strength.

"Who are you, kid?" Noticed there was another presence, Misaki asked with a sweet smile.

"Err..oh! I'm your brother's acquaintance." He blushed a bit since he finds Oga's sister to be quite a looker.

"Oh. That's weird. Oga rarely brings anyone back home besides Furuichi. Nice to meet you. I'm Oga Misaki. Tatsumi's sister. Your name?"

"Its Oku-"

"WHAT THE FUCKKKKKKKKK?" A loud scream that interrupted their conversation can be heard from upstairs. Without any second thought, the both of them rushed towards Oga's room. When they reached there, they found themselves Oga sat down on the floor looking all stunned. "See," Misaki spoke up. "I told you there's a woman in your room." It's true. There was an eye-catching woman stood inside Oga's room. She has emerald colored eyes and shiny blond hair. Everyone would start interpreting she's a foreigner after seeing her not-so-asian face.

"Young Master, you're safe." To everyone's surprise, the woman uttered out of nowhere. "Did she just call you 'Young Master'? HOLY SHIT!" Misaki exclaimed then landed her hand on Oga's shoulder. "Congratulations, bro" was her last word before she exited the room since she thought it was better not to meddle with the young couple's meeting. "'Yo-Young M-Mas-Master'...?" Oga stammered at the sudden name she just called him.

"Not you, mortal. The kid behind." She corrected the misunderstanding.

"Wha…? Me?" The blue-haired kid pointed at himself in appall.

"Yes, Young Master."

"Okay, okay. What's going on here? Why is there an egoistic looking woman in my room and how did she even get here?" Still perplexed at the occurrence, Oga asked no one in particular. "Moreover, why did she called you 'Young Master'? She's your maid or something?" The brunette glanced at the so called 'Young Master' with his index finger pointed at the blond-haired woman. "Don't point your dirty finger at me, fool." She hissed at the teen and walked towards the blue-haired kid. "So you chose this man to be your parent, Young Master?" She gestured her hand towards Oga in a rude way. What…? Parent?

"Err…I'm sorry but who are you?" The kid asked the unknown woman.

"What are you talking about, young master? I'm your maid, Hildagarde. I'm here to serve you."

"Since when I have a maid! Not to mention a hottie." The kid shouted and thought, 'maybe we did have a maid all this time but Yukio didn't tell me 'cause he wants to keep her to himself. Yea, maybe it's that.' "…..Anyway what's with the parent thingy?" Oga barged into their conversation after his curiosity took over him. "Fool, did you know that young master came to this petty world so he could find himself someone worthy to raise him? It was an order by the demon king or more known as Satan." 'What…? Okay now it just doesn't make any sense.' Oga assumed in his mind. Then Hilda continued, "It was said that the first person he clings onto once he gets to this world means that the human was cruel and merciless enough to be chosen and raise young master to become a demon king where he could destroy the whole humanity. It seems that he chose an ignorant like you to be the parent." She finished her sentence.

"Wait! Wait! WAIT!" The kid yelled, "What the hell do you mean? You lost me at the 'order by the demon king' part. Why does it sound as if I'm related to him?"

"Huh?" Hilda was a bit puzzled. "Of course you are related, Young Master. That's why he ordered you to find a ruthless, strong, doesn't-care-about-his-comrade person to raise you and become a great demon king to eliminate this world. So you could inherit his position."

"…And why? I'd never meet this 'demon king'."

"You're confusing me, Young Master. Did you lost your memory on your way here? You are his son. The Satan's son. Of course he wants his own son to be great like him and take control both of the worlds once his life runs out."

This was when silence conquered the moment. No one seemed to say anything after the whole 'The Satan's son' thingy. A shocked face was carved at each of them besides Hilda. The 'Satan's son' was the most shocked at the moment. Out of the blue, Oga asked the Satan's son something.

"Hey kid, what's your name?"

"It's Rin. Okumura Rin."

"Oh…doesn't sound anything like a demon's name…hahahahaha" Oga continued laughing hysterically after that. Maybe one of his brain's wires snapped after hearing such ridiculous statement. Yeah, raising the Satan's son. Definitely bad ass…
