Prologue

Falling asleep in class was something that Rin Okumura did only to often. His left cheek usually had a knuckle imprint on it, from being leaned on as his hair fell messily into his face, his mouth gaped open as he silently snoozed. His teachers made it a habit to slam things onto his desk every so often, especially his twin brother, Yukio Okumura, who took to slamming a textbook as loud as he could next to his hand that held his pen.

Today, however was a day that his brother halted from his daily routine as a familiar white dog waltzed into the room and hopped up on Rin's desk, peering up at him. Everyone was silent as they stared at the dog, Shiemi struggling hard not to try to wake Rin as she peered up at Yukio, who shrugged in return.

"Rin," The dog said, softly, tilting his head to the side and peering up at him, blinking. When the boy didn't wake he transformed into his normal self, sitting down his legs folded as he imitated the sleeping boy, his hand on his cheek, mouth open.

Rin groaned in his sleep, making the demon who sat in front of him, peer at him from under his hat, his ears twitching. The boy groggily looked up, then yelped jumping back, hitting his head on the desk behind him in the process. "What the hell?" he gasped, clutching the back of his head as he glared up at Mephisto, who was smirking in response.

"Little boys should not sleep in class, you know," he stated in a matter-of-fact tone. He stood up, twirling his umbrella in the process as he looked behind him, tilting his hat upward slightly, "Come with me, I need to discuss something with you," he stated, turning his back fully to him, and smiling up at Yukio. "Please excuse him, he will be absent through the rest of class," he stated, earning a small nod from the younger Okumura brother.

Run grumbled, grabbing his sword, and following him out, ignoring the curious glances from his fellow cram students. His eyes remained narrowed as he looked over the clown's dress for today. Once again, he was wearing his jester pants, making Rin roll his eyes and look off to the side, sticking his hands in his pockets. He glanced upward seeing a fat green hamster peering at him from on the rim of the demon's hat, and blinked. "Um... you know you have a hamster on your hat?" he asked, watching as it hopped down to sit on Mephisto's shoulder.

"Hm... yes," was his only response as he led him to a door, and unlocked it. He held it open for Rin to enter, then closed it behind him, striding forward to pass him. "Eins...Zwei...Drei..." Pop. In a puff of smoke, the man turned into a dog once again, the hamster standing on his back, still peering back at him, curiously.

"What exactly did I do this time?"

They stopped, the dog's lazy-looking eyes peered back at him, as if thinking of what to say exactly, "Do exactly? Nothing."

Rin blinked and furrowed his brows, "Wait... If I didn't do anything, why are you taking me out of class?"

"Taking you indeed. Where I am taking you is to see something, nothing more or less."

Rin gritted his teeth. He hated the way the other man made no sense when he spoke.

"You do enjoy the comfort of a woman, correct?"

Run blinked and stopped, looking at the dog, confused, "Um..." what kind of a question was this?

"Yes or no answer, boy, not that hard-"

"Sometimes... But not always..."

This time it was Mephisto's turn to be confused, "Come again?"

Rin rubbed the back of his head, "Oh sure I've been curious about girls, but never really... more..."

Mephisto's eyes were wide open as he stared at him, still very much confused. "I see..." he looked down, his eyes drooping again, "Looks like what I wanted to show you is invalid," he stated, turning and heading back in the direction they came from.

Rin followed him once more, "What do you mean?"

"My sister wanted to meet you... She find's you rather... What was the word... Enticing? But I'm afraid if you do not have a fondness for girls more so than curiosity, her task would be pointless."

Rin slowed his pace as he stared at Mephisto's wagging tail. He bit onto his lip, not realizing how hard his teeth were clamped on it till he heard the Principal's voice counting in German and turning himself back into his normal form, and leaned over, taking his purple glove off, and wiped at Rin's lip, then licking the blood off his own finger, his eyes narrowing as he smiled wide. "So, I have a question for you." Rin raised a brow, awaiting the older man's question. "If you are not interested in women, does that mean you have been with a man before, and that is why you prefer them?" he tilted his head to the side, smirking.

Rin's cheeks tinted pink at the question, making him gulp as he looked off to the side, "N...No."

Mephisto's eyes narrowed more as his grin widened to full capacity, "Interesting..." he stood upright and turned, walking down the hall, twirling his umbrella chuckling.

Rin blinked and rushed after him, "Why is that interesting?"

"Oh...nothing," he sang, opening the door and scooting out, holding it open for Rin, "I suppose this means it's back to class with you," he stated, still twirling the umbrella, the hamster grinning down at him as he opened the door to his classroom, and using his umbrella to push him inside, "My mistake," he sang to Yukio, who stared at him, confused. He smirked, closed the door and headed back down the hall, chuckling lightly.

"What are you thinking about doing?" the hamster questioned.

"Oh, we shall see... but this will be fun."
