A few days after the hectic battle against Inverse Tohka. Y/n has fully recovered and is down at the kitchen eating lunch. The the few days after the battle Kurumi moved in with her and Miku. Miku didn't approve of the move but she couldn't say no to her little sister. If you ask me i think shes spoiling her too much. Y/n then sees Miku in a get up as she approaches the front door.
Y/n: So Miku nee where are you going?
Miku: Oh im going to visit darling! Ill be back before dinner.
Y/n: Alright try not to be so clingy to shido. You almost killed him by asphyxiation last time you hugged him.
Miku: Mou!! I was only happy to see him!!
Y/n: You almost killed him. Good thing Kotori knows CPR.
Miku's face kept pouting.
Y/n: See you later Miku nee chan. Dont miss dinner okay?
Miku: With the way your acting, you look like the older sister.
Y/n: Hey im just looking out for you.
Miku: Yeah yeah, i have to go now bye bye little sister.
Miku then leaves to go to shido's house, leaving Y/n alone in the mansion. Kurumi went earlier to a cat cafe and she is taking her sweet time.
Y/n: What to do.... What to do.... Oh i can finish all the paperwork for the business.
Y/n the goes over to her office inside the mansion which originally belonged to her foster parents. She then looks a family photo of them at the back of the room.
Y/n: I miss you....mom....dad....
Y/n held her tears and looks at her desk, to her suprised the paperwork was already done and sorted.
Y/n: I guess I finished it earlier than expected.
Y/n thought for a minue before returning to her room. The room changed a bit during her time here but it still had the Black and white gothic look to it. The only major change was a PS4 at the west wall of room.
Y/n: I guess i could finish the Campaign for Air Combat 7
Y/n then spent 2 hours completing the game untill she got a call from Kotori.
Y/n: Kotori. I wonder what does she want.
Y/n turned off her console and stood up from her position.
Y/n: Kotori i know your spying on me so if you can hear me Teleport me to the Fraxinus.
Y/n on cue a bright light surrounded Y/n as she was teleported onboard the Fraxinus.
Y/n: Soooo what do you need me for Kotori?
Kotori was sitting on her command chair with her iconic black ribbons. She even has a lollipop inside her mouth.
Kotori: We'll for starters could you explain why you have such destructive powers? The measuring device used to measure a spirit's energy broke when you transformed into your Astral Dress.
Y/n: U dont really know but i did receive a Saphira Crystal from Phantom, but it was only half
Kotori: I see still doesn't explain the huge amounts of energy you released
Reine: I may have a theory Captain.
The two turn their heads to the sleepy scientist on board the Fraxinus. Reine Murasume.
Reine: My theory us that when the Saphira Crystal broke in two sthe resulting breackage released a large amount of energy. Refining the second half of the crystal giving it a enormous power boost.
Kotori: I guess that would explain it alot. Lets move on from that topic shall we?
Y/n: Okay? Why did you bring me up here.
Kotori: Well i want to negotiate a deal with you
Y/n: What kind of deal?
Kotori: You helo us Incapacitate spirits so shido can seal them and in return we wont persue your sister.
Y/n: Hmmm let me think about it.
After a few minutes of thinking, Y/n reached a decision.
Y/n: Okay I'll help you neutralize spirits for shido to seal. You have to keep your end and not try to seal my older sister. She still has some unfinished business to do.
Kotori: Okay okay we wont go after Kurumi. Wecome onboard, <Cardinal>
(So she has 2 allias <Akumu> is from DEM, Japanese for Nightmare. For Ratatoskr she is known as <Cardinal> I remember reading about it. It was codename for Soviet generals who helped the CIA during the cold war perfect name for someone who is going to help shido againts her own kind)
Y/n: Nice codename
Kotori: I just thought of it myself.
Y/n: So yeah ill help you and in return you will not try to persue sealing older sister.
Kotori: Deal.
Y/n: Can you teleport me back? I have to go eat dinner with Kurumi and Miku nee chan.
Kotori: Sure, Reine can you take her to the teleportation room?
Reine: Okay captain *yawn*
Y/n: Kinda feel bad for reine, not getting enough sleep.
Reine: follow me please
Y/n: Okay
Y/n follows reine towards the teleportation room. When they arrived Y/n gets into the pod and reine types in the coordinates of her destination.
The pod closes and a bright light shines in the pod. Before anyone coudl notic Y/n was back in her room being monitored by Kotori still.
Back at the Fraxinus
Kotori: Her help might just chage the course of this whoel situation.
Reine: I agree, in terms of raw power she could even surpass the first spirit.
Kotori: Not to mention her Inverse form.
Reine: We just have to orevent that from happening. She might go berserk and cause the end of the world as we know it.
Kotori: Yeah theres that
Kotori then unwraps another lollipop and puts it in her mouth.
Unknown location
Isaac Westcott was looking at his holographic screen when Ellen came into his office.
Ellen: Sir Isaac we have been informed that <Akumu> made a deal with Ratatoskr.
Isaac: Interesting. Well its not important to me. Whats important is to capture her at all cost.
Ellen: With all due respect Mr Isaac what does she have that you want.
Isaac: Well for starters I want to see her Inverse form and how powerful it is, if possible neutralize it. She was able to go and beat Inverse <Princess> in her base form. Imagine how powerful is her Inverse form going to be.
Ellen: The recovery team is already standing by on my orders.
Isaac: Good I want her, in this building, inside the containment chambers. We need to neutralize her Inverse form right now or else we'll be in big trouble in the future.
Ellen: I understand Mr Isaac.
Ellen the goes to leave the room leaving the CEO to his own thoughts. He then smiles looking a picture of Y/n in her Astral Dress.
