Anzai48 : LOL Mayu will become less possessive when she develops things from Yuki~ I dun have HW ! It just takes me time to go home from school~
The Stars and The 7 Stains
" Oi ! Come out ! " Yuki yelled at Mayu " What the heck are you planning, huh ?! And why am I tied to a chair ?! " Yuki asked as she gritted her teeth
A creak sound coming from the door went past Yuki's ear. A giggle " You are a feisty one. " Mayu had just came out from the bathroom. Yuki's jaw dropped. This was not the super intelligent hot Dr. Watanabe Yuuma she was seeing but Watanabe Mayu, an 18 yr old girl. To her expectancy, she wasn't expecting a neat and cute girl but umm.. ragged ? She despised Mayu until now. Seems like Mayu earned some points
" Hmm, okay. You got your demand. See ? You got to see me as a girl. " Mayu said as she crossed her arms and a smirk appeared on her face
" Y-Yeahh.. " Yuki blushed. Mayu went closer and closer to Yuki's face " Heh. And you will see more of it. " Her smirk grew wider
" Wh-what're you talking about ?! " Yuki's eyes widened
" Pfftch. Dirty-minded. " Mayu paced back and forth before she did a thinking pose and looked at Yuki
" What ? "
" Hmm... Do you have any objections, requests, demands, before we start ? "
" YES ! I don't wanna live here ! I don't wanna be your slave ! and I demand you to tie me off this chair ! " Yuki felt a buzz spread throughout her body. " ITTAI ! " she shouted and touched her neck as the tattoo glowed Green
" Hahaha ! " Mayu laughed " Stupid girl ! Didn't I warn you to obey me ? " Mayu smiled
" Aish ! I don't know anymore ! " tears started to fall down from Yuki's eyes. As for Mayu, always having a passionate side, she walked up to Yuki and knelt down so that she can face her eye-lvl contact. To Yuki's surprise, Mayu wiped Yuki's tears away " I'm sorry.. I've warned you so that you won't get hurt. Please, just obey me for once.Smile. " Mayu smiled a reassuring one
" This is your fault ! How can I smile ?! I'm deeply hurt ! I didn't sign up for this ! " Yuki squirmed as Mayu backed away coz' she was startled. Yuki looked at Mayu and she just stared at her blankly as Yuki continued to cry. Mayu had pity. She released Yuki from the chair and sat on her couch. " Okay. I've managed to grant all your requests. You can leave now, since you're not interested in this at all. " Mayu said as her face was full of regret and sadness
" R-Really ? You're letting me go ? " Yuki said
" Go away before I change my mind. " Mayu stood up and as she was about to go upstairs, a hand grabbed her wrist
" What do you want now ?? " Mayu glared at Yuki
" I've realized that you're not really just a Cyborg Doctor without a heart. You're more than that. So... I'll try to bear with you in this. " Yuki looked away blushing
" Pfftt... ha.. " Yuki looked at Mayu " What's so funny ? " Mayu burst out laughing " Then again, my Mind Games always work on you. " Mayu smirked " EH ?! " and at a flash of lightning,all the doors and windows are now locked " Woah ! H-How did you do that ?! "
" Well, sit. " Yuki sat down on the couch " Actually, I'm not normal. "
" I saw that when a Tattoo appeared on my neck. "
" Good. My father had tested me on one of his experiments, and now, I've become a person who can do almost everything "
" What ? "
" My brains are normal though... "
" You call your brains normal ?! You're super smart ! "
" I know. Anyway, about this slavery thing... Are you really up for it ? "
" Eh ? ... I guess.. "
" Then there's no turning back. Once you've agreed to my covenant, you are no longer meant to be freed. Your destiny has been changed to being a successor if ever something happens to me. You are now unable to do things on the will of the 7 Stains and the Stars. "
" Wait, what ? Explain slowly, please ! "
" Hmph.. That was slow. "
" That was slow to you ?! "
" Zip it or I'll make that tattoo extra painful when you do something against my will ! "
" Hai, hai~ "
" Ehemm.. That tattoo has many types. I have one too. " She showed Yuki one on her wrist that appeared magically " It's name is 'Nezumi'. Yours is 'Black'. It's a symbol that YOU are MY PROPERTY. That is the main reason why you can't go against me. My blood is combined with yours now. "
" Umm.. How exactly did this tattoo form ? "
" You see, my veil or venom has circulated throughout your body. Which means, you're now affected and you've become like me. Invincible. " Mayu smirked as she said the last word
" Ahh.. So umm 'Black' gave me a power ? "
" Yes. You have to discover that on your own though. Also, you can control to make it appear but you need training. "
" WHAAT ? So it appears anytime ?! "
" Well, no. It appears when you go against my will. "
" Oh, yeah, I knew that. " Yuki smiled sheepishly " What's the 7 Stains and Stars you we're talking about earlier ? "
" The 7 Stains are the things that made the Earth imperfect and bad. Very deadly to us. The deadly stains are; hypocrisy, questions, mysteries, changes and nothingness. "
" Those are only 5 ! "
" I'm not done, stupid. "
" Oh. "
" Those 5 stains are the most deadly ones. Hypocrisy; you shall not be false to yourself and I. Only be hypocrytic when you need to. Questions; To me questions are very very rude. Do not ask too much questions that are to obvious on what you're plotting. Mysteries; As I am now, I'm trying to solve mysteries. But you are not permitted to get involved in such mysteries. Changes; DO. NOT. EVER. CHANGE. Nothingness; .. unexplained on how it's so ironic but do not get into voids. Got it ? "
" What's a void ? " Yuki curiously asked
" A void is a black hole which people like us get sucked into. Basically, TRUST. Don't trust anyone except me. "
" Ehhh! " Once again, a buzz hit Yuki. " OUCH ! Wtf is with this Black thing ?! " she touched it again and it glowed Red. As she looked at Mayu, her eyes we're purple and some kind of sign was formed there and it disappeared. Back to it's original form
" What was that ??? "
" You don't trust me ? I read your mind and controlled Black to do that. You have to trust me. "
" Hai. Okay. I'll try. "
" Don't try. Do it. Anyway, there are 2 more Stains, correct ? First one is IMPERFECTION. Imperfection is perfection. "
" What ? Imperfection can't be perfect ! There's an IM there ! "
" Once, all the people we're perfect. Equal with greed, lust, pride and all of those. Until the Stains stained the world. People started to feel too confident of themselves and became too Perfect that they became Imperfect. Therefore, Imperfection is Perfection. "
" You're really smart. I don't think I'll get along with these stuff "
" Don't worry. You'll get to it, soon. Last one is Love. " Mayu said as she blushed to the word love
" Ehh ?! Love is a Stain ?! "
" Yes. Well, Love is... love. Nothing more, nothing less. I only know that love is the only thing that really hurts the most. That is why, you shall not fall in the hands of LOVE. "
" Mayu, have you ever been in love ? "
" No. I don't believe in love. It's... stupid. "
Yuki sighed " You'll get to it soon, Mayu. "
" Oh, a tip. Black cannot overcome Love. The only stain it doesn't react to. I don't know why though. I didn't do too much research on love "
" Why not ? "
" I might fall in love. To know love you have to experience it, right ? "
" Yeah "
" And I don't want to fall in love. Enough about that love and shit, let's move on to the Stars. "
" Hmm are those the stars in the night sky ? "
" No. These stars are different. There are 7 for the basics. Have you noticed Black glows into different colors when you go against the Stains or my will ? "
" YEAH ! "
" Those are the Stars. They are colors. 7 colors, 7 stars. There are a lot of Stars, really but.. It's complicated to tell you. You wouldn't understand. "
" Hey ! You saying I'm stupid ? "
" What do you think ? "
" .... "
" There. You should learn to answer your own questions. Questions is a Stain. "
" AHH ! I forgot about that ! "
" Hmph. Anyway, the colors you may encounter are Red, Purple, Blue, White, Green, Yellow, Orange and Black. Each one symbolizes a Star. "
" Ahhh.. "
" I think you had a lesson from school about the meaning of the colors, right ? "
" Uh-huh. "
" Good. You may know and there's no need for me to explain. Last information, the colors we're invented at 1666 by Isaac Newton. 666 is the devil's number which means Stars are bad things. Avoid them. "
" Okay. "
" I've explained to you all the things you needed to know. Now, I'll tell you my objective. "
" I'm all ears. "
" My objective is to make Imperfection REAL PERFECTION. "
" What ? How are you gonna do that ?? "
" I've collected a lot of data. From Businessmen to Yakuzas who want to do the same thing. Only a few are left now, since I've assasinated them all. "
" You kill people ?! And you're a Forensic Pathologist ?! "
" Yes. I'm not the Justice type of person. I just want to fool the law. "
" You are really a smart kid. "
" Oh, yes, I am. And I want you to help me carry out my objective, Yuki. "
" Since I've agreed to this, ... Okay. I'll follow what you'll say. "
Mayu sat on Yuki's lap facing her " What a clever and cute dog, indeed. Obeying and following what's right is good, Yukirin~ " Mayu smirked and kissed Yuki again. Yuki's eyes widened but unlike their last kiss shared, this one was full of feelings. A passionate kiss. It felt good. So she kissed back unknowingly. After some time, Mayu pulled back.
" Yuki, if you finish the tasks I give you, you might just get rewards from me. " Mayu winked at her seductively and stood up leaving Yuki wondering about what she said.
" Yuki, I guess that would be all. Ah ! By the way, remember when I said I'd take you home with me ? "
" Y-yeah ? "
" Your luggage is in your room. Next to mine. " Mayu smiled and went to the kitchen
Yuki sighed " I guess... being a slave isn't as bad as it seems, eh ? " Yuki smiled.
