On Yomi's Tardis.

Yomi was dressed in a black business skirt adjusting her as She sat down before Yuuko and Miharu as she crossed her arms, "Ok then let's say the nightmare force is thinking using my sister's mind that means she'll expect me to show up in my tardis and try to force it out of her system."

Miharu raised her hand and said, "But she won't expect Yuuko to be the one to force Akihisa to purge it!?"

Yuuko looked to her and blinked and Yomi nodded and said, " why yes that is true!" She then hand Yuuko a knife.

Yuuko's eyes widen as she jumped and asked, " why the hell did you just give me a knife!"

Yomi rolled her eyes, "A time lords system purges upon regeneration, how do we regenerate? We die and move on to our next lives! So you will need to sneak up and strike Akihsia with this!"

Yuuko gasp as her eyes widen in horror as she said, "What the hell did you just say!?"

Miharu then got beside Yomi and said, "She said if you want the Akihsia you love back, you got to kill the current one! Now come on we have to distract an evil alicorn and you have to kill your true love!"

the Pegasus then fainted were she stood form the horror of what was just said to her.

Meanwhile on the Alien planet it's people were in rags chained and bowing to Queen Aeternitas who was sitting on a throne that looked to be made form dark magic clouds and bones as she sighed and raised her check on her left hand.

the Evil Queen said, "I mean come on it's been a week I know my good good sister is not so good at the time and date part of time travel but this is just stupid! I am waiting on a battle of wits in which I will win and spread my emperor here!"

At that point a Red Tardis appeared and Aeternitas rose up and said, "About bucking time!"

At that moment The door opened and Yuuko Yomi and Miharu walked out and Miharu's eyes widen as she looked up and down the evil form of Akihisa.

Miharu's jaw dropped and said, " hi Akihisa!" she sounded stunned.

the Evil Queen smirked and said, "One it's queen Aeternitas now! And two Miharu this view isn't for you, Yuuko my darling what do you think!?"

Yuuko had a nose bleed and blinked before she let out " I like muffins!"

the evil Alicorn time lordess giggled as she covered her mouth with her hand, "aaww I stunned her stupid with my beauty!"

Yomi had her sonic in hand and said, "sister please stop this! This isn't you just fight it long enough you know the regeneration system purge can not only cure you of this parasite but destroy it!"

In a moment the four anthro ladies found themselves on top of a castle as Aeternitas rolled her eyes and said, "why would I want that! My greatest fear out living Yuuko won't happen! With all this extra power I can simple pause time around her making her as eternal as me!" She said as she summoned what looked like a board sword make of dark magic mist.

Yomi turned to fire a sonic pulse but a veil of dark mist covered Aeternitas as she charged through it and Yomi's eyes widen as she avoid to the left to avoid the sword, witch's blade slashed right through the stone like it was nothing.

The Evil queen shouldered her blade and said, "did you really thing the same tricks would work on me? I know all you got and how to counter it! IF you won't join me Sister dear then I offer you this deal leave your sonic and tardis and leave! You may live so long as you are never before me!"

Yomi adjusted her glasses as her horn glow red making a red energy blade come form her sonic giving her a beam saber katana witch she charged to sword fight with her sister as she said, "Poor Celestia! I know how her cartoonself feels now!"

the two Time lordess clashed blades of magic rapidly before the Queen took to the air and made her horn blow to fire off fireballs.

Yomi was then panicked as she was slashing fireballs and looked to Miharu who just stood there nose bleeding, "STOP LOOKING AT MY SISTER AND HELP ME WOMEN!"

Miharu then shock her head and turned to fire off a horn energy blast only for what looked like Skeletons made of Black mist to grab her and make her magic stop.

Aeternitas laughed evilly as she said, "you think I won't protect myself form a threat!" she laughed not even looking at Yuuko who was now hovering behind her! The Evil Queen then said, "I know who's a threat and who isn't and I know how to counter! You can't win!" she then felt what seemed like Yuuko in tears hugging her form behind.

she looked back and calmly said, "I will comfort you later my love, but right now…!" she then yelled in pain as Yuuko let go and the evil queen fell to the ground on her knees her dark magic constructs vanishing as she grabbed at her stomach and pulled out a knife and held the wound.

She stood up shaking a golden glow coming form the wound as she looked to Yuuko in shock and horror.

Yuuko was in tears and said, "I'm sorry Akihsia this just isn't you! This isn't the pony I love! It's the nightmare force! I hope you'll forgive me when you are yourself again post regeneration I'm sorry!" She then covered her face crying as she fell to her knees repeating that.

Queen Aeternitas's eyes widen as they returned to normal as black mist start to leak form her slowly returning her to her normal Alicorn form as she reached for Yuuko smiling as she said, "I understand and thank you my love!"

the golden light soon covered Akihisa giving her a new form she was still female, but she no longer had wings or a horn, She was brown furred and black maned with blue eyes she was still dressed in Queen Aeternitas outfit.

The Anthro earth pony girl then stood up and stumbled over to Yuuko who had fallen to her knees and she fell down on top of her uncovered yuuko's face and kissed her happily.

Yuuko returned the kiss in tears just as much as Akihisa.

Miharu just blinked and said, "well now… that happened!"

Yomi then used her sonic to summon her Tardis she walked in then walked out with a copy of her sister's sonic and hand it to her as she said, "yes it did and if I was ever turned evil I would hope you would do the same for me!"

Yomi then used magic to pick up her passed out sister as she said, "come on let's get her out of here!"

Yuuko got up sadly and walked in Followed by Yomi and Miharu.

Later on back in the normal Tardis.

Akihsia was hugging a crying Yuuko, " It's ok Yuuko I'm here I'm here and you had no other choice I'm still here and I still love you!"

Yuuko cried and said, "but I stabbed you In the gut!"
