Prologue

      up there is what Aika looks like

--------------------------------------------------------------------------------------------------------------------------------

"Sebastian, I demand an explanation! who was that pest?"

Sebastian only grinned down at Ciel as he put his hand across his waist and bowed down to his master.

"that "pest" you are talking about my lord... is actually one and on-"

THUD

the sound of the boy falling down the stairs and the glass breaking is heard through the empty hallways. Ciel's head snapped towards the door as his eyes glowed into the crimson red color, he stood up from his king sized chair and stood still staring at Sebastian as he stared right back at the blue haired boy with a teasing grin.

"too much trouble! take care of the boy, bathe him, dress him up! afterwards, send him to my office..."

Ciel sat back down to his chair and leaned backwards, crossing his legs and putting his hands in his lap.

"Yes my lord.."

Aaah~ how Sebastian wanted to play with this new toy, Ciel had NO idea. with the small smirk Sebastian left the office with Ciel staring daggers at the door. Sebastian walked to where the boy had fell with only the sound of his boots clicking. Of course, there was no one there, a vase was shattered on the floor with flowers laying on the ground lifeless.

with a small sigh, Sebastian pinched the bridge of his nose and left, looking for the boy he has saved earlier.

Meanwhile the boy named Aika was running around in the house looking for the exit, the more the boy looked, the more harder it was becoming, his vision was still blurry, he didn't understand where he was, and he was scared out of his mind. soon enough, he gave up and hid in the closet in one of the rooms upstairs. he hugged his knees tightly bringing them close to his chest as he sniffed, he wanted to go back to his home, he wanted to see his parents once again.

Sebastian walked upstairs as the sound of his boots clicking was heard through the empty hallway, a teasing grin danced on the devil's lips as sniffed the air, his grin only widened. Sebastian grabbed a door handle of Ciel's room and slowly opened it, it made the creaking sound. He stepped inside and looked to the left, then to the right.

He hummed lowly and approached the closet door. his lips drew upwards into a wide smirk, his hand reached for the door and opened it slowly as it made the creaking sound.

Aika was there hugging his knees, his blonde bangs covered his left eye as the other shined in a bright emerald green color through the sunlight. Sebastian kneeled down and reached out a hand for Aika to take with a warm and reassuring smile.

Aika looked at Sebastian and hesitated. he didn't know whether it was safe to take the demon's hand or not. he was scared, yes he was. when Aika looked at the demon's face, suddenly everything around him disappeared, his heart started to calm down as his eyes softened at the warm smile Sebastian had on his face. Aika's hand slowly reached to take the demon's hand still hesitant a little.

Sebastian scooped Aika in his arms. Aika wrapped his arms around the demon's neck, while Sebastian held him by his hips, "W... who are y-you...." the boy asked stuttering, his voice was a music to Sebastian's ears, he has never heard someone who had as sweet voice as Aika's.

The demon chuckled lowly and replied with a small grin, "Sebastian... Sebastian Michaelis at your service~"

"....... Aika......" he said quietly, quiet enough for Sebastian to hear him.

Sebastian only grinned in return. Aika hasn't raised his head from the demon's neck as they left the room.

"W..where are we g-going?..."

"I'm going to bathe you first, get you dressed and then we will go down the stairs the meet my master." Sebastian replied quick.

"M-master?..."

"Mmhm~ Ciel Phantomhive, the one I've made the contract with."

"Oh."

Aika nodded as they walked into a different room this time, this time the room was all white. Sebastian walked into the different room once again and scooped him into the bath. he stripped Aika out of his clothes in a swift movement. Sebastian started to bathe him humming a soft tune with a teasing grin.

he saw Aika's smooth and slender neck, he brushed his fingers against Aika's neck, then he was bought back to his senses and stopped. 

after the bathe, Sebastian put the clothes on Aika. they were now walking down the stairs, the smaller male's eyes were still blurry as he stumbled a bit but was quickly caught by Sebastian, "now now, be careful little kitten~" he grinned.

"S-sorry..." the boy said simply, looking at the wrong direction. Sebastian has noticed this but decided to stay silent about it.

They were now standing in front of Ciel's office door. Sebastian gently knocked on it only to hear a faint, "come in." in return.

Sebastian opened the door for Aika, he looked up at the demon who grinned teasingly and then the office and stepped inside.

Ciel stared at the smaller male deadpan, his eyes furrowed slightly as he recognized the smell of the Nephilim, "You bought... Nephilim here?..."

Sebastian bowed slightly, "I have my reasons mi'lord..."

The demon smirked secretly as he recomposured himself standing still. Ciel had eyed Sebastian for a while now with a raised brow, his eyes seem to glow in crimson red cokor as if studying Sebastian.

"..... Very well.... Your name?" Ciel glanced at the green eyed male in the corner of his eye.

Aika took a step forward and looked back at Ciel, "My name is Aika..."

He said and put his hand across his heart as if saying that he was grateful for what Sebastian did, but in his own way.

Ciel cracked a small smirk barely visible, "Mmhm... Names Ciel... Ciel Phantomhive... The lord of this mansion you have stepped into..."

He gets uo from his seat and fancily walks towards the smaller male slowly, "and i.... Have a few rules i need you to keep at any costs..."

The boy was confused by the actions of Ciel but nodded anyway, "first... As you have already noticed... We are out of the maids... I want you to be one... Sebastian will give you the uniform... I want you to come whenever i tell you to... Got that?.."

Ciel looked down at the smaller male as his eyes flickered inti the crimson red color. Aika quickly nodded and looked at the wrong direction again.

"second... Don't cause any trouble, or there will always be the punishment waiting for you..."

"third... Don't talk back to me... Like ever!..."

"the last but not the least... Fourth rule..." Ciel smirked and leaned down to Aika whispering huskily in his ear, "you do... Everything i tell you... After all... I have your family in my hands~"
