Chapter 1

"... I'm really curious of Yui-neechan's whereabout... Not only she haven't contacted us for almost two months, the people in the church wouldn't even tell us where she is" said a girl whose wavy purplish silver hair falls just slightly under her shoulders as she twirled in her newly made purple-white sweet lolita dress with stripes, a lot of frills, laces and ribbons.

"By the way, how's my new dress? It's cute, right?" she asked to her other three sworn sisters. One of them, a 17-year-old dirty blond-haired girl in generously exposing sleeveless white shirt and very short laced shorts with white belt - sighed and peeked at the girl.

"Hm-mm... Yea, it's good, Mayu..." she said with bored tone as she sighed.

"Really? You think so, Lacie-neechan?" the girl called Mayu said with a delighted smile.

"Angela?" Mayu called for a girl with very long white hair who was busy knitting a scarf. The girl named Angela snapped out of her sea of thoughts when Mayu called her.

"How's the dress I made for you? You're comfortable with it?" Angela gave a seraphic smile and nodded as Mayu eyed at her white 3/4 sleeved-dress with striped hem underneath a rose-coloured laced jumperskirt and her wide ribbon tie. There's no hair accessories for her because for Mayu, Angela's silky white hair are the accessories itself.

"Urgh... I'm so bored... Where's Kuro-neechan anyway?" Lacie groaned as she rolled herself on the couch and accidentally hit a certain brown-haired girl who was sitting on the same couch causing her to drop her book. The brunette groaned and glared at Lacie who didn't even give a hang of her mistake.

"Hey! What's this? You just knock the book that I was reading! Now I've to find back the page that I've lost" she scolded as she stood up.

"What?! It's not my fault! Who asked you to sit here, on the same couch as I do" Lacie retorted.

"What?! Apologise and I might forgive you for the mistake" the brunette replied, only to have Lacie's scoff.

"Hell no, Miss Nichola Anne!"

"Urgh!"

"Argh!"

Mayu and Angela tilted their heads as they silently watch the routine cat fight between the two. Yes, it is their routine to at least fight once a day. It was serious at first for them and only their oldest sister would be able to stop them. Eventually, it bores them and they just let them do what ever they want - unless it turned worse. Then, the door of the room opened and a head peeked into the room.

"Getting along well I see..." the black-haired girl said as she stepped inside, revealing her full body - a slender girl clothed in a V-neck white shirt that exposed a bounteous amount of cleavage underneath a sleeveless black jacket with fur-bordering hood. Her languorous black eyes looked at the girls in front of her.

"Okaeri... Oneechan..." the younger girls greeted in unison.

"Where have you been?! We're so bored, you know" Lacie complained.

"Only you, that is" Nichola said.

"Did you search Yui-neechan's whereabouts?" Mayu asked.

"Did you?" Angela nodded. Kuro smiled and lifted a piece of paper.

"HOW?" the four said again in unison with shocked and amazement.

"I have my ways... And apparently, the relatives the priest mention are someone we've never know..." Kuro answered.

"The relatives... Who?"

Kuro looked at the address on the paper which were given by one of the boys she forced to spill out the information.

"Sakamaki... And she went to a famous night school called Ryoutei Academy" Kuro explained.

"Ryoutei Academy? ... Oh, it's that school for prissy rich brats and idols if I'm not mistaken" Lacie said. Kuro nodded.

"So, now that we've known where Yui-neechan is... Shall we go and visit her?" Angela suggested. Kuro yawned.

"Yes we will..."

"Really?" Mayu said almost delighted when Kuro replied, "But not today or tommorow..."
"Eh?!"

"Don't "eh" me... I'm exhausted right now and I really could use some sleep... Good night." And with that, the raven went straight to hit her sack.

"ONEECHAN?!"

"Sakamaki... Huh...? I don't know... But... Hmm..." Angela murmured with her own self.


"What a creepy mansion..." a commented slipped smoothly from Kuro's lips as she stared at the ominous-looking mansion of the Sakamaki estate. It's weird how the driver just sped away after they got off the taxi.

"I wonder what's up with the driver?" Mayu questioned.

"Don't bother him... Let's just focus on meeting our beloved sister that we had been lost contact for almost two months already and see what's wrong?" Lacie said, gaining most of the girls approval as they walked pass the entrance gate while Kuro just stood at her place, unmoved. Her suspicious eyes looked at the gate like it was a portal to another world far beyond they were right now. Her sisters were far in front already at the other side of the gate. Kuro didn't shake off the feeling and walked towards the mansion.

"Whoa..."

"It didn't look THAT big when we're at the gate" Nichola said.

"How luxurious can her life be that she forget about us" Lacie commented.

"Yui-neechan... Forget about us?" Angela asked.

"Don't make such speculations..." Kuro scolded the girls gently as she looked at the majestic foyer and the surrounding rose gardens.

"Let's see if anyone's home" Kuro proposed.

KNOCK

KNOCK

"Hmm... It's either they're not around or they're all deaf" Lacie said with a shrug when there were no answer from the inside after a long series of knocking and waiting. All except Kuro sighed.

"What now? We don't even bring anything with us to wait for her..." Angela said.

"I say we leave... We can visit her another time" Nichola said.

"All of you wait at the garden... I'll go take a look around" Kuro said with ordering tone as she moved away from the foyer to explore the rest of the estate.

"Ah... And she's gone" Mayu said.

"She said wait... Hmm... Hm? Hey look!" Lacie alarmed the three girls as she pointed at the opened door.

"Eh? It's open already? We should call Oneechan" Angela said.

"She's gone already" Lacie replied impatiently as she walked towards the foyer only to gain Nichola's protest.

"Lacie! Oneechan asked us to wait here!" she said. Lacie pouted. Then, an idea struck her mind.

"Aww... Look, Nichola is such a good-girl... Obeying Oneehan~ Or maybe, she's just scared..." the sly girl said as she went towards the door.

"Why you!" Annoyed with Lacie's words, Nichola dashed towards the door and entered along with her.

"AH! Nichola-neesan!Lacie-neesan!" Angela called.

"Mayu-chan... They went inside."

"Huh... You must be kidding me... And they are supposed to look after us..." Mayu sighed.

"What to do now?" Angela asked.

"We'll have to follow them then" Mayu responded. The two entered the mansion. And as they entered deeper into the mansion, the doors behind closed without a sound.
