It was the silent, dead of night. Not a sound was heard throughout the city. Then, the sound of something hitting wood is heard. Deep within the forest, two figures run into view before vanishing. A flash of red hits a tree, while a flash of pink went past them.

Then silence......

A ice shard hits the ground at high speeds. Then another. And another.

Frost covers a tree as the pink color passed it.

Silence......

A pillar of ice appears and rises to the sky. Standing on that Pillar was Serafell Leviathan in her magical girl outfit. Her bangs cover her eyes as she stared at someone who approached the pillar.

Serafell: You'll pay..... You'll pay!

She rains down more ice shards that keep freezing the area. The person dodges them and runs up the Pillar. They pull their weapon back and slam it into the top as Serafell jumped off. The pillar breaks as the person is left midair. Serafell makes a ball of ice and throws it, causing the person to shift their position and slice the ice boulder in half. The two then land on the ground.

Serafell: Deleting my save data was a big mistake (Y/N). I would have trained you if you asked.

The person walks out of the dark, revealing themselves to be you, (Y/N) (L/N).

(Y/N): I did ask you. Three days in a row. Before and after school and throughout the day. And you kept saying no because you wanted to play Dark Souls!

Serafell: But you deleted all my hard work! Well then, you wanted training, so I'll train you until you freeze!

She slams the end of her staff on the ground as a burst of icey wind fills the area. Then, the area freezes as multiple ice spikes come from the ground bringing that area into an Arctic apocalypse.

The spike of energy wakes up two peerage kings. Rias Gremory and Sona Sitri. Sona prepared to head to the area alone, while Rias wakes up her peerage before going to the area. When they get there, they see the frozen forest and meet each other.

Rias: Sona?

Sona: Rias. You've come to check this out too?

Rias: Indeed. It woke us up. And you too it seems.

Issei: I-i-it's f-f-f-freezing here.

Kiba: Agreed. Let's make haste.

Sona: I already have a feeling on who this might be.

They begin to walk, moving out of the way of the many ice spikes in the area.

Akeno: Who could have done this?

Rias: Sona, any thoughts?

Sona: One. But I would like to hold my judgement until I see for myself.

They then hear fighting and head to that direction. Their stopped when something crashed into Issei. More so someone. Issei lands on his back as the person sits on his face.

Serafell: That hurt you know! When I-

She stops and looks around at the people. When she sees Sona, her expression turns from angry to happy as she hugs her.

Serafell: Sister!! How are you? Why are you out so late? Don't you have school?

Rias' peerage is silent as they look at the two sisters. Issei still on the ground, perving at the fact that he had a girl sit on his face.

Rias: Mind explaining?

Sona: Haaa.....Serafell, meet Rias and her peerage. Everyone, meet Serafell. My older sister.

Serafell: Oh! I already know about all of you. (Y/N) always talks about you all.

Kiba: Wait. (Y/N)?

Serafell: Oh. Didn't she tell you about me?

Everyone looks at each other except Sona, who looks to her sister.

Sona: (Y/N) you say? Where is she now?

(Y/N): Oi Sera! You giving up already?

Everyone looks up to see you in a since spike looking down at them. You hold both of your Scissor Blades.

(Y/N): Oh. Hey guys. What's up?

Sona: Vanguard. Get down here.

Hearing the slight aggression in her voice, you comply and land beside her.

(Y/N): Y-yeah Sona?

Akeno: Oh my~. So obedient~.

Sona: Why are you fighting my sister? More importantly, how did you meet her?

(Y/N): Okay. So, Y-you see-

Sona: No excuses. No stuttering. Tell me. NOW.

(Y/N): O-okay okay. S-so one day Rias wanted me to kill a stray devil. When I went to the location, I ended up meeting up with her. She kept bothering me until she wanted to live with me. So I accepted and now she lives with me. Ever since she's just been at my apartment. T-the reason I'm fighting her is because I'm trying to link better with Senketsu. The reason I'm fighting her is.....

Sona: ....Is? I'm waiting.

(Y/N): Umm.......Well.....Uhh.

Sona: Hmm. I see. Serafell, why are you fighting my girlfriend?

Serafell: Girlfriend?! I didn't know you are in a relationship!

Sona: I don't have to tell you everything about me. Now, why are you fighting her?

Serafell: She deleted my Dark Souls save data!

Hearing that makes you take a few steps back.

Koneko: Ouch. That's a little too hard don't you think?

(Y/N): L-look, she doesn't do anything else. I asked her for a week straight!

Serafell: It was three days.

Sona: Hmmm. I see. Well then. (Y/N).

You flinch as you heard your name.

(Y/N): Y-yes?

Sona: Me and you are going to have a nice long talk over the weekend.

You jump a little and nod.

Sona: Now then, it would be best if we all went back to rest. We have school in the morning.

Rias nods as her and her peerage leave first.

Sona: (Y/N), one more thing.

(Y/N): Y-yes?

Sona: Restore my sister's save file. I know you kept a back up.

Serafell: Wait you kept a back up!

(Y/N): I back up all my games. Even for your files.

Your then hugged by the girl before she returns to your apartment before you. Before you can leave, Sona pushes you against a frozen tree.

Sona: Try anything like that, and I might drown you.

(Y/N): N-noted.

She smirks and kisses you. Before you can kiss back, she pulls away.

Sona: Sorry there Vanguard, but think of this as part of your punishment.

(Y/N): W-what's my actual punishment?

Sona: You'll see~. Try anything, and I'll just make it worse~.

She licks your neck before teleporting. You let out a breath as Senketsu turns to normal.

Senketsu:

(Y/N): No kidding. She wasn't holding back. How much time can I last?

Senketsu:

(Y/N): That's enough to get back. Let's go.

You return to your apartment and rest, forgetting about the frozen over area of the forest. The next day, you enter the school, seeing Sona waiting.

Sona: Good to see that you've come.

(Y/N): And fear your wrath? I'd rather stay on your nice side.

Sona: Well too bad. Your already on my bad side. Just you wait. I'll have you begging when I'm done with you.

You gives a nervous chuckle before you two enter the building.

(Y/N): S-so how are things?

Sona: Well, finding out that your living with my sister is one thing. Her almost freezing you alive is another. I'm surprised your able to handle her. She hasn't had a strong opponent in a while.

(Y/N): Glad to know that. Although, I feel like she wasn't really serious.

Sona: She didn't want to kill you of course. So she must have held back to an extent.

(Y/N): Anyway, are you free after school? Maybe we could go out somewhere.

Sona: Well, I can clear my schedule during school and have nothing afterwards. But, don't expect anything.

(Y/N): Guess I deserve that at least.

Sona: Now, he get to class. Or I'll make your punishment worse.

(Y/N): I'm going I'm going.

You make your way to class and enter to see nobody there except Mikisugi.

(Y/N): Huh? Where is everyone Mr.Mikisugi?

Mikisugi: Oh, their in a different class. I need to talk with you in particular. So, come sit.

You do so, feeling nervous for some reason. Mikisugi rubs his hand through his hair, slicking it back and taking off his glasses as a purple light fills the room.

Mikisugi: Tell me. Are you planning to fight Raynare?

(Y/N): Huh? How did you know about that? Are you also trying to kill me!?

Mikisugi: No. The opposite actually.

You look at him confused. He reaches into his shirt and pulls out a sewing needle.

Mikisugi: This is my Sacred Gear, Endless Stitches. I'm able to change it's size and shape. It's able to sew anything, living and non living.

(Y/N): Woah. That's cool. What else can it do?

Mikisugi: I'm able to throw it and make it come back. I can also make multiple of them and hit certain pressure points to stop parts of the body from moving or freezing them in place. But, enough about me. Answer my question.

(Y/N): O-oh. Well, yeah. She's planning something with a nun that come to town-

Mikisugi: Asia correct?

(Y/N): How do you know that?

Mikisugi: I've been keeping an eye on you. Your the only one who can have the strength to save the world. Not only that, but I saved you from the fallen angel that tried to kill you back then.

(Y/N): What do you mean? Save the world? And what about that fallen? What's their name?

Mikisugi: I can't tell you that. But, I can tell you something that I found out lately.

You and Senketsu wait in interest to see what he means.

Mikisugi: ........Your not the only one with a Kamui.

Your eyes widen slightly. Senketsu's eye also widens.

(Y/N): Another Senketsu?! You can't be serious right?

Senketsu:

(Y/N): So your really serious?

Mikisugi: Definitely. I don't know who owns it, but it's name is Junketsu.

(Y/N): Junketsu......Purity? Whoever is it, maybe I can talk with them and get them on our side. Plus, if it's purity, then maybe their nice.

Mikisugi: You can hope all you want. But I don't know anything else. But, that's for another day. For now, you'll need this.

He hands you a Seki Tekko, but with a blue star on the palm.

(Y/N): Huh? A Seki Tekko? But I already have one.

Mikisugi: This one is special. You could say it way a gift from your girlfriend.

You blush a bit before taking it from him. You take off yours and put on this new one. It feels alot more comfortable. It also feels like magic is flowing through it.

(Y/N): Wow. I gotta thank her for this. It feels nice.

Mikisugi: With that being said-

He fixes his hair and puts on his glasses.

Mikisugi: -I'll be heading out. Nobody is going to come back to this room, so stay as long as you like.

(Y/N): You sure?

Mikisugi: Of course. Even allow your girlfriend in. Oh, but make sure you clean up here. I don't want to do it.

With that, he leaves the room. You lean back in the chair and kick up your feet.

(Y/N): Another Kamui Sacred Gear......

Senketsu:

(Y/N): I hear ya. But we still need to be careful.

You look to the Seki Tekko and see the star glow slightly. You stare at it before sighing. You pull out your phone and send a text to Sona.

(Y/N): There's only one thing to do when you need to waste some time.
