A/N: Yeah, so this is my first fanfiction, don't go easy on me. I need to learn how to improve my writing so I can be as awesome as the other people on this site. Anyway, I appreciate any criticism including harsh ones, because that tells me that there is, in fact, someone out there that finds my work in need of their strong opinion. So, I get something out of it. As embarrassing as it might be, I won't even mind if you type a five paragraph review on why I shouldn't exist in this world because of how horrible I write (although I do find myself at least mediocre, if not average). Ah, it doesn't matter.

Oh yeah, before I forget, this fanfiction has it set where the Ishiyama students are aware of demons. I might add a little omake someday about how they found out. Also, I'm not an expert on Walpurgis Night, so I may have tweaked things. A lot.

On to the story.

It was a bright and sunny spring day. Perfect weather for a morning stroll to school. Warm, pleasant, peacef-

"GYAAAAAH!"

"Shut up."

Never mind.

As usual, some poor souls foolishly attempted to extort money from the very, very handsome, cool, respected by all young man. Being the caring and upright human being he was, this young man "lectured" them on the wrongness of their acts.

So he kindly proceeded to beat them up and bury them in the walls of nearby buildings.

"Ah, are you finished, Oga?"

"Hurry up, human."

There standing on the sidelines were Furuichi Takayuki and Hildegarde. Furuichi was lazily texting on his phone with one hand, and distractedly playing with his hair using the other. Hilda just stared on at the comical scene of carnage, whilst ignoring the countless pleas for mercy and cries for help. Her eyes locked with the cause of the extortionists' misery. "Baby-on-Back Brawler", "The Rampaging Ogre", "Chief of Ishiyama", Oga Tatsumi. They glared at each other for a moment before Oga turned away and rubbed his neck tiredly.

"Yeah, yeah. I hear ya."

"So, explain why you're here again?" Oga was sitting at his desk staring at Hilda. They were waiting for class to start, and it was rather noisy in their room. But what was important was the fact that Hilda was there. It was rare for her to attend class, so when she insisted on following them, he was taken aback.

"Tomorrow is April 30th," she declared as if it was obvious. Furuichi and Oga just continued to look at her, waiting for an explanation. She gave them a condescending sigh and began to speak again.

"April 30th is Walpurgisnacht. It is the night where demons become more powerful, in simple terms."

Furuichi narrowed his eyes in confusion and thought for a moment. After several seconds, he looked at Oga playing with Baby Beel in his lap, then back at Hilda.

"But isn't Walpurgis Night just a day when witches are allowed to make mischief before "the land returns to life"? It's some kinda holiday in eastern Europe with bonfires and stuff, right?"

Hilda gave another exasperated sigh and shook her head.

"No. In the Demon World, Walpurgis Night is the time when your powers increase exponentially. You take on a different form to contain the excess energy and celebrate at a festival. It is custom to display your strength and there is even a ball to present others with the beautiful body you have temporarily gained."

Oga looked up from his fun with Beel and turned to look at the two.

"But why are you here today? Can't ya just go home and study cooking so that you don't kill everyone with your freak ass hell food?" Oga promptly received a face full of Hilda-cookies, but she still answered his question.

"Young Master is still an infant and cannot properly control his powers. He is also of demon royalty, and that makes it unpredictable when determining what will happen that night. So I am here to monitor the changes in Young Master of today and tomorrow. It would be bad if something was to happen and the whole city was destroyed. I don't want to clean up something so troublesome."

Both Furuichi and the revived Oga sweat profusely at the idea. In their minds, they imagined a scene of Baby Beel electrocuting everyone to death. It wasn't very pretty. Furuichi just laughed awkwardly and fidgeted in a nervous manner. Oga, who only understood half of it, glanced back down to Beel who cocked his head to the side confusedly.

"Aih?"

The rest of the day went fine. Maybe a bit loud and annoying on Oga's part, with the extra company and all, but otherwise fine. Beel luckily didn't act up at all, and had been rather quiet throughout the entire school session. Hilda seemed to notice and she became a bit worried. Even if it was the day before Walpurgis, her Young Master was sensitive to the shift in demonic energy. Hilda had explained during lunch break that sometime before Walpurgis, demon's powers would weaken. She compared it to the waves during a tsunami. Before the tsunami strikes, the water recedes, being drawn in to build the power of the deadly wave. Oga had just grunted as if he wasn't interested in things like demons. But if you looked closely enough, he had a concerned glint in his eye as he looked up at Beel resting on his shoulder. He quickly looked away, too fast for anyone to notice.

They arrived home later that day in silence. Furuichi had gone to his own house after reassuring Oga that it would be alright. Even if he hadn't seen Oga give any indication to his concerns, Furuichi had known the stubborn man long enough to realize the unspoken distress. But in truth, it wasn't what Hilda had said that was worrying him. It was the way that Baby Beel was acting. He didn't tell anyone yet, but something odd happened earlier that day.

-Flashback-

Oga collapsed on the ground, laughing breathlessly after running away from Hilda's watchful eye. He was sprawled out on his back with Beel sitting on his chest.

"Haha, hey Baby Beel. That has gotta be the greatest escape from Hilda I have ever succeeded in. Actually, that's the only time I've gotten away."

He looked up at Beel who was sitting quietly on his chest as it quickly rose and fell. Beel crawled towards Oga's face and situated himself on Oga's neck. Beel's eyes were shadowed and he was uncharacteristically silent. Then, Oga felt a sudden and threatening burst of demonic aura weave itself around Beel's body like shadowy tendrils of darkness. He slowly moved the chubby hand toward Oga's forehead, eyes glinting dangerously. When his hand touched center of his "parent's" head, Oga's eyes widened and his body jolted. All he could feel was emptiness. As if all the power was drained from his very soul, and left to stay in the rotting shell of his body. Then, nothing.

…

Oga had awakened to find that it was near the end of school. He figured he passed out, but from what? I can't rememb—Baby Beel! That's right. I was… Oga looked around him to find Beel hovering over his face, looking worried and confused. Oga stared at Beel for a while, and then sighed. He couldn't really understand what happened, and that feeling of emptiness. It must have had to do with the withdraw of power before Walpurgy something. But, even though he should tell Hilda, he felt like… Like Beel woudn't want hime to. Like Beel would be angry if he did. He thought about things for a while as he absentmindedly pat Beel's head.

-End of Flashback-

Oga and Hilda didn't speak at all as they prepared for bed. Hilda left to sleep with Misaki after bidding her Young Master a good night. Oga lay in his bed and stared at Beel. With nothing else to really do, he just flopped on his bed. Beel crawled near the pillow and remained silent. Oga had a bit of a staring contest with Beel, but he lost interest and stared at the ceiling. His hand was throbbing a bit. It made him tired and want to sleep, even though he didn't want to, really. But, it was getting harder and harder to stay awake. So as Oga drifted into a stated of unconsciousness, he felt as if someone was calling him. No one was there, though. Other than Baby Beel, who was watching him.

"Oga…"

Who is calling me? Who…? Oga drifted to sleep while thinking about who could possibly be calling him. He couldn't think clearly and his vision was fading to black.

"Oga…"

A/N: And there you have it. All finished. I may or may not continue this, it depends. But I most likely will, since I already have the next chapter or so done. I got bored. Seriously bored. Updates will be in a day or few, just because I want to hold it out for a while. Hopefully this story is looked at by one person. And hopefully that person will point out any mistakes I made.
