(Y/N): I'm sorry what?

???: Wow. That's the second time you started a chapter with that saying! Is it a catchphrase?

(Y/N): Catchphrase? Who? What? Mikisugi, who the hell did you even create? Her voice is already annoying.

Mikisugi: Right right. This is Nui. I made her based on you.

(Y/N): Based on me? What does that mean?

Mikisugi: Well, she is your direct equal. I made her to be a counterpart in a way.

Nui: Yeah! You can say we are sisters! I always wanted a sister! Hey, can we fight now? I want to see how strong you are.

(Y/N): Guess I have no choice. Can I use Senketsu now?

Mikisugi: Yes, you may.

(Y/N): Fucking finally.

As you go to pull the pin, it gets stuck. Leaving you to groan and try to pull it with your teeth.

(Y/N): God damnit! This stupid thing! Senketsu, get this thing unstuck as I fight.

Senketsu:

You bring back out your blades and dash at the doll. She easily sidesteps you and kicks your stomach, sending you into the forest.

Nui: I'll go and train her privately. Be back in a few hours~.

She covers herself with her parasol before vanishing.

Kiba: Quite the unique thing you got there.

Koneko: You said that Nui is basically the same as (Y/N). In what ways exactly? Just physical measurements aren't really make them the same.

Mikisugi: Well, to be more precise.....

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

Your back glides against the ground before you stop your sliding with your blades.

(Y/N): Damn. She kicks hard.

Nui: I can kick harder if you want!

You quickly get to your feet and turn around, seeing the doll behind you somehow.

(Y/N): How did you get there?!

Nui: It's called being fast. Anyway, let's continue!

(Y/N): Don't you have a weapon? I'll feel bad if I kicked your ass and you didn't stand a chance.

Nui: Oh! That's right!

She reaches behind her dress. She let's the weapon spin around her wrist before pointing it at you. Both yours and Senketsu's eyes widen....well Senketsu's eye. Another scissor blade. This time in a purple color.

(Y/N): You......how?....But....

Nui: Did you not hear master? I. Am. YOU.

You can't stop staring at the blade. Your hands are shakey as you slowly take some steps back. You couldn't react as you get kicked again, sending you through some trees before landing on your back.

Senketsu:

(Y/N): I'm f-fine. I'm fine. That hurt like hell. She's strong.

Senketsu:

You start to get back up, but get kicked in the face. You go through one more tree before landing again.

Nui: Wow. Your really weak. And I'm supposed to be you? Wow. What a shame.

You get up and grab your blades before looking at her. You don't know what's up with her, but you can't let your guard down. By feeling a shift of wind, you turn and block Nui's blade with yours.

Nui: There's the fight I've been wanting! Come on sister! Let's fight until we both fall!

(Y/N): Shut up! Your pissing me off!

You kick her as she slid back a bit, but she wasn't fazed as she re-engage with your blades. She's fast. Very fast. And without Senketsu's extra strength, speed and overall power increase, your at a disadvantage. You push her back and try to catch your breath while staring her down. Nui just gives you a big closed eye smile.

Nui: Already out of breath? We're just getting started you know.

(Y/N): Could you be any more annoying?

Nui: Yes I can actually! Come on out!

You see smaller Nui's fall from her dress before clouds of smoke appear. Your eyes widen as you see more Nui.

(Nuis? Nu'i? What's the plural for Nui? Nuis doesn't sound right in my mind.)

(Y/N): I'm already hate this. Senketsu, got that thing unstuck yet?

Senketsu:

(Y/N): Better get done quick. I'm not gonna be able to handle for long.

You prepare for the potential beatdown you were going to face. The clone dash at you, swinging at you with their own blades. You manage to block them, but there are too many that you get overwhelmed and try to back away, but your blocked as some stand behind you. You cut them down before running deeper into the forest. You turn your head to see the dolls quickly approaching. You start slashing them down One by One, but it's still not enough as it seems like they double with each you kill. Your guard dropped as one grabs your arm. You swing her around and slam her into a tree before cutting her head off. One gets on your back and another grabs your leg. Your able to free your leg, but the one on your back keeps trying to restrict your movement. You kept running with the extra weight while killing more dolls.

Nui: Good good! Your improving! The more you fight as a human, the stronger you'll become!

(Y/N): Shut up! Your high pitched voice is annoying!

You slam the one on your back into a tree, getting you free. You stand your ground against the multiple clones.

Senketsu:

(Y/N): It's fine, don't beat yourself up over this. And besides, I need the exercise.

You start fighting against the clones again, running out of steam quickly. Your normal strength limited, but your definitely pushing yourself to your limits. You raise your blades above your head before slashing downwards, sending two red slashes forward, killing multiple clones.

Nui: That's a new move! Your already learning!

(Y/N): I said shut up! I'm already sick of you!

You send more slashes of energy at her and the clones. She keeps piling on pressure that you get overwhelmed. Your arms then get grabbed from behind. You try and slash the many still coming your way, but your range is limited. You take alot of punches before they let up and back away. Your blades are removed from your hands as you look at the doll.

Nui: My oh my~. My first real fight being alive and I'm already so excited! We should do it again when your stronger!

(Y/N): Senketsu, I'm in a bind here!

Senketsu:

Nui: Say, why don't we play a different game?

(Y/N): A different game? When I get free, your gonna-

You didn't get to finish your sentence as you get kicked below the waist, right in the balls. Your eyes roll back as you feel pain surge through your body. Your body shakes violently for a bit before you look at the ground. Your body struggles to intake oxygen. Your gripped by the hair as your eyes gain focus, looking at the living doll.

Nui: Time for game 2! I personally jammed your transformation device to prevent you from changing. You'll be able to transform when I'm done with you, but for now, let me explain our game. I'm gonna beat you up. More specifically, I'm going to beat you to the brink of death. All those other Protagonist get power boost from almost dying, so it should work with you.

For once in your life, you stare at someone with fear. You were powerless against her without Senketsu. The only sound that filled your ears were the giggles of the Doll and her clones.

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

Issei had soon returned, having been exhausted through his training. He falls onto the couch as Asia walked over and started healing him. Everyone was sitting around as Mikisugi explained more of what Nui is.

Rias: So let me understand. Nui isn't really a copy of (Y/N)?

Akeno: She's a theoretical scenario of her being at her peak.

Koneko: That's a stretch if you tell me. How would you be able to guess what her peak would be?

Mikisugi: Look, I know it sounds far fetched, but believe me when I tell you, Nui is stronger then she looks.

Issei: I still don't know about all this. Your just our teacher. Yet you know so many things that a normal teacher wouldn't.

Rias: I do agree with Issei. What are you really?

Mikisugi: You want to know. Then I'll tell you.

He snaps as the blinds over the windows close. He slicks his hair back, giving off that purple stained glass tint. He takes off his glasses and unbuttoned his shirt before letting it glide down his shoulders but still staying on his elbows.

Mikisugi: Who am I? I am Aikuro Mikisugi. To be honest with you, your previous teacher was taken under custody so I can take his place.

Issei: Wait what!? Why would you do that?!

Rias: I find it unbelievable as well. But, let him finish Issei.

Mikisugi: As I was saying. I had to do it so I could get closer to (Y/N). I was actually the person to set up her meeting with Senketsu.

Rias: Really? Then that would explain alot. But, I'm still not too convinced. Your still hiding something aren't you?

Koneko: Yeah. And can you put your shirt back on?

Mikisugi: No can do. For, I will tell you. I run a secret organization. Nudist Beach!

Everyone was silent as the man waited for their response. A droplet of sweat falls from his forehead before clearing his throat.

Mikisugi: As I was saying. I am the leader of Nudist Beach! The goal of Nudist Beach is to keep balance between the human world and the world of you devils and angles.

Rias: I see. Your not from Japan are you?

Mikisugi: Correct. I'm actually from America. But, Nudist Beach has spread all across the world. We even have a base in Japan here. You could also say I'm here for work.

Koneko: Still, your sounding crazy.

Mikisugi: Alright. I get it. But, you just have to trust me. One day, I'll tell you all the real reason that I want to train (Y/N).

Rias: Alright alright. Anyway, shouldn't Nui and (Y/N) be back by now?

Mikisugi: Trust her. You may have just met her recently, but she is worthy of your trust. Although, they might be it be back until tomorrow.

Akeno: Hmm. I wonder how her training is going....

Koneko is getting a bad feeling, and she definitely doesn't like it. She doesn't know why she would be so worried about you. Knowing you, your able to handle yourself......but she can't shake the feeling.

Akeno: Koneko?

The girl jumps a bit before looking to the queen.

Koneko: Oh. Sorry. I was thinking.

Akeno: That is alright. You were spacing out for quite a while. Rias wants everyone to take a break before we continue training.

Koneko: Okay. I'm going for a walk.

She gets up from the couch before leaving. She goes and sits under a tree. Maybe she's just overreacting. You'll be fine...... You'll come back fine......she hopes.....

Koneko: This....feeling.....Could I.......be interested in her?....No......I can't be. That wouldn't be right. She has Sona. It'll just be wrong to confess to her....
