Title: Tanya Mistake

(Kuroryuu P.O.V)

When I heard that overpowering outburst of Ki that came from the hospital building. I immediately rush there to see what is going on, when I got to the rooftop of the hospital to my surprise what I saw was a little girl with blond hair, her clothing is a wreck and I can see things like her underwear... bra and other things.. I am not a pervert okay?

I am not into little girls to begin with, so what I am seeing should not disturb me in the slightest.....

I hid from her in the shadow and lower my presence to the extreme in order to avoid detection from her. Since I can feel something from her that is extremely dangerous. This girl is definitely not normal. So I try to hide with the best of my ability from her.

However, when I saw her face..... I was stun by her immature beauty, I am sure that she would be my type of girl if I was to give her 5-6 years to grow, but because I was so stunned by her looks that I had revealed my presence a bit. But it doesn't seem like she had detected me at all and she looks to entirely focus on something else with her eyes close.

Shiver!

Suddenly I felt like she had discovered me or something, but this feeling only lasted for a second. But it was definitely there like there was something inside of her that has detected me already.

Just who is this little girl?

Even though my hiding ability is not the best, but it should not be that easy for someone to detect me and those that can detect me when I am hiding from them, is only those that are on the same level as my father. So for her to detect me... she must at least be on the same level as a Slayer.

Which should be absolutely impossible!!!! even in my home world, there is no slayer that young and even I, who is said to be the youngest slayer, had never heard of someone capable of being a Slayer at such a young age.

So I just watch her from afar, not daring to get close in order to not start an unnecessary fight with her. However, I just can't help, but stare at her face and body, which made my face turn red.

(Come on... even if others call me a beautiful girl, I am still biologically male so I can't help, but blush when I am looking at a half naked beautiful little girl, okay? Yes this is perfectly normal and it prove that I am not a girl....) when he started to have dirty thoughts about her, he felt like that thing inside of her had stared at him again, but this time, it was full of malice like it is telling him to go hell....

Flash!!!

Suddenly that girl's body glow with an intense light that made it somewhat difficult even for him to see her. But after that intense light coming off her body had disappeared, she was also gone and this had left him dumbfounded.

Where did she go?

When I tried to sense her presence from the surrounding, I can't detect her at all like she had just vanished from this world... could she... be?

Is she..... an.... X-User?

That was the only explanation that he could come up with since the only other explanation is that she belong to 'that' Slayer Clan. But those 'people' would never venture out into the normal world. So it can't be them. So she can't be anything other than an X-User..... but if she is.... then that is too bad....

Since... all X-Users are his enemy.... so she is his enemy..... because they are the killer that had slain mother....

(P.O.V End)

On this day, Tanya made a bigger mistake that she will have to deal with later in time.... but that is not the only mistake that she had made on this day. Her second mistake was her ignorance to Silver plans and that Silver did not tell her about the meeting that she had with Len.

(Tuesday Night)

After, Tanya had given Len a kiss to the forehead and Left. Silver use some of her powers to enter Len mind again. Since after the last time that Silver had invaded Len mind, she was able to build a connection between them and was able to create a telepathic channel into Len mind. So even without Tanya kissing Len directly in the lips, she could open a channel into his mind whenever she wants.

One can think of it like Silver has found Len mental Address and can hack into his mental network and system whenever she wants. So the lesson here is to never let silver invade your mind or else you will regret it. Since once she enters, she is not leaving until she forge a way back into your mind.

Naturally, she did not say a word to Tanya about this.

“Len, do you remember me?” Silver said to Len, as she took a seat next to him in a movie theater that is created by Len mind.

Len was staring at a movie screen that playing the scene of him fighting Tanya when he was possessed by that shadow. But when he look over to his left, he was surprised to see her being there and said with a doubtful expression.

“Silver-Oneechan? Why are you here?!” he said to her in surprise.

“Haha... I am not here to visit you Len, but here to do business with you. Since this matter involves your cooperation as well.” she said with a small laugh.

“What matter?” he asks her inquisitively.

“I want you, to let yourself be posses by that shadow again.” She said as she looks at the movie screen and made some fake popcorn to eat as she watches.

“WHAT!? ” however, Len only look to her in pure astonishment after he heard her say that.

“Of course, I don't mean it that way, Len. What I want you to do, is not to let that shadow take over your mind completely, but only just enough to fool him into taking over you and believe that it had total control over you. But when the time comes I want you to completely steal his powers and destroy it from within. Since I failed last time, I believe that it is only right that you should do the job instead. Since I believe that the reason of why I had failed to destroy him, is not only because of my carelessness but also because of 'that' person and if I try to destroy that shadow again, there is no stopping him if he was to interfere just like last time. So, this time, I want you to be the one that annihilates that shadow once and for all and so quickly that 'he' could not interfere in time to save him.”

This tale has been unlawfully lifted from Royal Road; report any instances of this story if found elsewhere.

“But Silver-Oneechan... will this work, can I do it?”

“It has to work and you must do it or else Tanya can never be at ease for the rest of her days because she does not know when that shadow will attack you again. Which will not only interfere with my grand plan. But also put her in danger of being exploited by the enemy because you could not protect yourself.”

“... I am sorry Silver-Oneechan..”

“Don't be, since I am the one who is asking you to risk your very existence for my own selfish gains. Len, this is the only method that I can think off. Since you can't become an X-User anymore and to become a martial artist takes times, even if you perform a special technique with Tanya in bed. It would not be stable. So I want you to completely become a Z-Monster like that shadow in order to protect yourself from now on. Since that is the only method that I can think of for you to be stronger in the short time frame that we have.”

“Why?”

“That shadow is created from the grudge of all those who had failed their dreams and their hopes crush to bits. You had once completely fused with that shadow, which means that you are not even a pure human in terms of existence and is now part of the opposite existence to that of an X-User. So you are incompatible with an X-User powers and even if I give you a Soul weapon or gear in order to turn you into an X-User, it will only lead to your demise, because of the rejection of your soul and the soul of the X-User that had their wishes and hopes put into it. While yours is tainted by that shadow with despair and loathing.”

“Even now I can see some part of you is not like that of a human, for example..... your right eye..” once she said that she materialize a mirror for Len to see.

Once Len saw his reflection in that mirror, he instantly became frighten because his right eyes are like that of a serpent's eye glowing in crimson madness. But that is not all, his hair that was blond in reality, is now partially black inside of his mind. Once he opens his mouth, he can see that part of his canine teeth is sharp like that of a vampire.

He instinctively held his body close, and shivered in fear of what he saw in the mirror that is reflecting himself that was inside of his mind. But then he heard Silver voice that snaps him out of his fear with her soothing voice.

“Though, I am not sure about the fact that you can't absolutely become an X-User since Enigma-X is the creator of X-User, only it would know if you can or cannot become one. but it is too risky for you to become an X-User Servant because if I give you the Soul Gear that father had. It is almost safe to say that you would not be able to fuse with it. So this is the only option that is left now and my powers of granting wishes are limited right now and so I can't help you in that department either. So I can only offer you a method for you to obtain power. But this method will involve you to discard your own humanity for power. So will you do it?” Silver ask as she looked deeply into his eyes. Her scarlet eyes have this charming power that made him feel calm and notices under her gaze... sorta like his decease sister Shera-Oneechan....

While under her gaze, he felt that he is not scared of himself, while under her gaze, he did not feel that he is not a monster, while under her gaze, he feels genuinely like her little brother and not the monster that had harmed her... he simply could not help, but feel charm by her gaze and that he could not resist her demands.

“If I do.... would Silver-Oneechan and Tanya-Oneechan still think of me as your little brother and not the monster that I will become?” that was the most important question he wanted her to answer before he could give his reply to her request.

“... Ha.. ha... HAHAHAHAHA!!”However, she only looks at him in surprise and then started to giggle and laugh out loud.

“Silver-Oneechan!!! that was a serious question!!” he told her seriously, but it only made her laugh harder. When he showed an annoyed face at the way she is laughing at him, she then stops laughing and said.

“Len... I don't care if you were not a human, I don't care if you were the evilest person in the world, I don't care if you were the greatest person in the world, I don't care if you were a devil. I only care about you because you are my and Tanya little brother. What you become does not matter to us, since you are our only little brother and we will still love you only for that. Monster or not, if you still act like you, talks like you, thinks like you, no matter the form you take, you are still you and you are our cute little brother. Does that answer your worries?” she said that while giving a sweet smile to him.

“That is unfair Silver-Oneechan... saying it so thoroughly like that...” Len blush when he saw her smile and turn his head away in order to hide his embarrassment. However, Silver then gave him an embrace that made him become more embarrassed.

“Huh? I thought you want a thorough reply from me. So I merely told you as it is..” she whispers sweetly into his ears like a succubus. Which turn his face redder than any tomato and his heart began to beat faster than normal.

“Think of this as my gift to you in order to help you succeed in my request.” after she said that, she gave a sweet smile to him, then disappear from his mind and return back to Tanya.

However, Len can only stare dumbfounded at the place that she disappear and give a small, but happy smile to her last words. Then said.

“Silver-Oneechan, even if you can fool Tanya-Oneechan... you can't fool me.... Shera-Oneechan....” he said quietly as he watches the rest of that movie inside of his mind.

When he awaken the next day, Tanya was already gone and a silver blade was pointed to his neck.
