Sins of the Older sister(A Azur Lane x FNAF crossover)

XXX(Chapter 30) and Epilogue

The Moment Weser and Eugen heard their older sister's orders, Eugen immediately checks the monitors where William is and notices a button and presses it, causing William to stay away from the screen that he is using to take control of Freddy giving Hipper some time to prepare a much stronger anti-virus while Weser closes some metal doors and the vent as Roxy, Chica and Monty are trying to enter, with Eugen annoyed as the wolf manages to survive that, plus as time goes on Huge tentacles made of wires started to appear from the holes that are sealed in to room, causing the group to dodge them incase the got pulled by those 

This happened for 8 mins. until Weser burned William for the third time causing the three animatronics not to return, giving everyone a sigh of relief

Until Roxy slammed the wall where the vent is 

Roxy: I'll find you, you sleep slut

Eugen: Round 2 so be it then

Since Eugen has a strength of a shipgirl, she uses some of it to fight Roxy head on

And at that huge hole that Roxy made William entered it and was about to go close to Hipper, until he noticed Weser and then goes to her instead

As Hipper saw this she realizes what he is about to do

Hipper: Weser, get away from him!

As Weser heard those word it was to late, William grabbed Weser from the throat slowly some parts of her body turns into liquid metal and starts to transfer to William's body, giving him the ability to speak now

William: S-so this is one of Helen's c-creations?, F-fascinating I'll take your metal as mine now

As Weser heard this she can hear Hipper screaming her name until William summoned a knife as he used some of the metal to make it and throws is Hipper's chest, causing her to stop and cough some blood with Freddy carrying her, angering Weser from what happened to her sister 

Weser: This is my body

William: W-What?

Weser: THIS IS MY BODY, SO DON"T TOUCH WHAT'S YOURS!

and then the liquid metal in William's body suddenly started to crush him, causing him to drop and scream on the floor in pain and then it returned to Weser, but she make the the blade stay on Hipper's chest as it might kill her instantly is she removes it, as Hipper is stabbed in the aorta

With Eugen landing the final blow in Roxy's head, sending it flying and killing her, She , Eugen and Freddy who is carrying Hipper left the area as it starts to collapse with the massive amalgamation of animatronics taking William's body up 

And as they escaped the area and saw Butcher and Tallinn in the car with Daycare Attendant and Vanny(Who is still unconscious) some boarded the car while Weser stayed with Hipper on the back trunk of a car to assess her condition as they left the Pizzaplex as it starts to collapse with Hipper finally passing out due to shock

Epilogue

The Incident of the Pizzaplex collapsing went worldwide and investigations were made, with Eagle Union, Ironblood, and Fazebear Corp managing to cover up the real truth even without Hipper using her authority, safe to say she is glad every employee in the Corp. is loyal to her

As for Hipper, a surgery was made to reactivate her wisdom cube as it is the only way to heal the damage that William done to her, it worked, but because of this Hipper became a shipgirl and since It'll damage her work as a CEO, she made a AI to handle the Corp. and checks the situation from time to time

Freddy became Gregory and Elizabeth's Family personal bodyguard, as Hipper discovered that he has no family to back to causing Elizabeth to adopt him, and making him Annabeth's older Brother, while Daycare attendant became a full time nightguard for the main Fazebear Crop.

3 Years later, the Siren War ended causing Hipper and some shipgirls to retire, causing Hipper to return as CEO, but works at home to spend more time with her sisters

and they all lived happily ever after
