Author's Note

Please don't hate me for writing Celestia this way and don't kill me if there are spelling errors in this. Thank you. This is the first time I have written a Twilestia fic where Celestia is a yandere so if I don't capture the yandere aspect very well then I am very sorry. All in all I hope you enjoy and expect more chapters to this story as well. I believe I have written the very first yandere Celestia x Twilight, so I hope that this story inspires other writers to write more yandere Celestia, because Celestia being a yandere or rather anypony being a yandere is a great concept.

If you want me to continue to write this story then leave a like letting me know you want to read more.

I am speaking for all writers out there, don't dislike a story without reading it first and don't hate on a story just because you don't like the ship that is presented. If you don't like the ship then don't read the story.

SHE ISN"T YOURS!!

It was a normal day for Celestia, wake up, raise the sun and do day court, such is the life of Princess Celestia, so when she finished and went back to her room she took off her regalia and tossed it aside. Celestia used her horn to place sound canceling spells and lock spells so she could have some privacy for what she was about to do. She went to her bed and pulled out a chest from under her bed which had many magical locks on it so no one could open it. Celestia used her horn to unlock each lock on the chest before opening it and looking inside. She used her magic to take out photos of Twilight Sparkle, her faithful student and began to smile at them before levitating more and more photos of Twilight out of the chest, there where photos of Twilight's birthday, her accomplishments, and some with just her and her mentor. But there were some where Twilight didn't know her picture was being taken. There were some of her walking down a hall, looking at a book, her in ponyville, talking to her friends, even some with Twilight going to the bathroom.

Celestia looked at all the photos of her beloved student and smiled a happy but creepy smile. She loved looking at these photos of her Twilight.

"I don't care if having these photos makes me a stalker, I will have you Twilight." Celestia said creepily.

Celestia sniffed and kissed the photos before placing them back in the chest and putting the magical locks on the chest and slide it back under her bed.

Celestia's head rose slowly, her smile turning sadistic as she spoke "I won't let anyone get in my way of my love for you..... no matter who it is. I don't care who I have to 'get ride of' to be with you my love."

Celestia rose from where she was on the floor and made her way to her bed to get some much needed shut-eye for tomorrow, for she had a certain purple alicorn to see. When she finally fell asleep she dreamed of the one thing, or, one pony she loved.... Twilight.

The next morning Celestia rose to raise the sun so she can begin her day off. Her sister told her she needed a day off and that she can handle all the work will she was gone, which Celestia was greatful for because Celestia needed this day off. Celestia went to the balcony and spread her massive wings to take flight, once in the air she began to make her way to ponyville. Some ponies saw her flying to ponyville but she didn't care, she was extremly powerful she could do what she wanted when she wanted and no-one can say otherwise, and there is a reason why no-one says anything.

Celestia flew over hills and passed through the trees to get to her destination, once she got to ponyville she hid in her favorite tree which was the tree she used to stalk Twilight from on a monthly basis. All that was left for her was to wait for her beloved Twilight to walk by and get groceries from the market which was every week at 5pm because she only buys enough food for that week before going go get more.

Celestia used her magic to summon binoculars to see her Twilight, she peered through them seeing Twilight with groceries walking back to her home but then she saw what she hoped she would never see in her long life. She saw a mare with golden yellow fur and a rich orange mane and a sunflower for a cutie mark walk up to Twilight and kiss her.

An audible snap could be heard as the binoculars were snapped in two then set on fire before disappearing. Celestia's eye twitched and her teeth grinding with anger as she saw some random mare kiss HER! beloved Twilight. She couldn't stand it she had to get rid of that mare so Twilight can be all hers and only hers. Celestia knew exactly how to get rid of that mare to.

She climbed down from her tree and began walking over to Twilight and her prey.

"Hello Twilight, how are you today." Celestia asked in her serene and calm voice. But in truth she was beyond angry at that mare that Twilight's with, but can't say nor show it because Twilight was there and she didn't want to risk being hated and rejected by her love, but then she would most likely foalnap Twilight and make her love her anyway.

Twilight jumped back, visably startled by the sudden greeting but soon relaxed noticing it was her former mintor.

"C-Celestia, what are you doing here?"

"What, am I not allowed to visit my former student?." Celestia feigned being hurt by Twilight's comment.

Celestia looked down to see that mare still there so she put on a smile when she saw her and asked.

"I'm sorry Twilight, who is this you are with?." Celestia said faking curiosity

"Oh this is Sunflower Seed, my marefriend." Twilight said holding her marefriends hoof.

"Oh I didn't know you were dating someone, congratulations Twilight." Celestia faked being happy. The truth is she might be nice and kind to that mare on the outside but on the inside she was seething with anger and murderous intent towards her.

"Well thank you Princess thats very kind of you."

"Might I ask how you two got together?."

"Something told me you were going to ask that." Twilight giggled before telling Celestia how they met. "it was about 3 months ago and I was always interested in gardening so I tried it but low and behold I kinda suck at it, thats when Sunflower walked up to me and asked if I needed help which I accepted because I needed it and then one thing led to another and we started dating, we've been happy together ever since." Twilight finished with a blush.

Sunflower kissed Twilight on the cheek who began to blush. "Yep Twily here is pretty bad at gardening, she actually managed to burn the flowers without doing anything, how she did that I will never know but I can tell you that I am reallly happy being with her Princess." Sunflower said turning to her marefriend and smiling.

Celestia was doing her best to restrain herself from tearing this mare apart for kissing HER Twilight. 'How dare she kiss my Twilight and call her Twily, she is my love, not yours, there is no place for you. I'm going to enjoy watching you beg and plead for mercy and i'm going to laugh as I tear that false hope out of you by tourturing you until you die.' Celestia thought.

"Yep, Sunflower makes me happy, I love her." Twilight nuzzeled Sunflower's neck when she spoke causing Sunflower to blush heavily.

"Well i'm very happy you found someone but I think I need to head back to canterlot you know how the ponies get when they see there princess is missing for more than two seconds." Celestia giggled as innocently as she could doing her best to hide her unbridled rage.

"Oh, well I geuss I will see you later than, bye princess." Twilight said waving to Celestia before walking away with her marefriend.

'Soon Twilight, you will be mine and that mare will be out of the picture.... for good.' Celestia's happy smile turned maniacal when Twilight was gone."Hahahaha." Celestia quietly laughed maniacaly to herself.

When Celestia was sure they where gone she decided to follow them.

Celestia teleported in Twilight's castle and hid, waiting for them to get home. She watched the castle doors open to reveal Twilight and Sunflower. Twilight had her wing draped over her marefriends back as they walked in. Once they were in they closed the doors behind them and made there way to the kitchen to put away the groceries.

"I can't believe Princess Celestia came to ponyville." Sunflower said putting away some vegetables.

"Yeah, she likes to visit me from time to time to see how i'm doing and how my studies are coming along."

"Well I can tell you one thing Twily" Sunflower walked up to Twilight and whispered in her ear "Your my Princess."

Twilight's ear flicked as she blushed furiously. "S-Sunflower." Twilight stammered out.

"Well that's enough teasing for now" Sunflower said with a sly grin "Let's finish putting away these groceries, then we can have some fun, ok." Sunflower winked and kissed Twilight on the cheek.

If Twilight's face could go more red it would but she was already as red as tomato. She could only give a nod and started putting the groceries away with Sunflower.

From where Celestia was she was able to hear every word that her Twilight and that mare said to each other. Celestia's rage was just about to go overboard and she would have killed that mare right where she stood but she decided to wait. Celestia saw the two exit the kitchen and make there way over to the library to read. She saw the two on a couch with a book and Twilight had her wing draped over that mare's back as they read together. 'I want to read with Twilight like that.' Celestia thought as she kept watching the two.

Every now and again Twilight would kiss Sunflower on the cheek and Sunflower would do the same. This tore Celestia's heart apart seeing that. Celestia watched Twilight for hours looking at her well toned flank. She was practically drooling as she looked at it. She saw Twilight get up and place the book down on a table which brought Celestia back to reality.

Twilight and Sunflower went up the steps and toward the bedroom. They walked in and closed the door behind them, walking up to the bed they got in and wrapped up in the covers getting ready to sleep but turned to each other and gave each other goodnight kisses.

"I love you, Sunflower."

"I love you too, Twilight."

"Goodnight."

"Goodnight."

Celestia teleported in the bedroom and watched them fall asleep. She carefully waited until they were both deep in sleep and decided now was the perfect time to get rid of that mare so Twilight can be hers and hers alone. Celestia walked silently up to the bed and used her magic and placed a knock-out spell on her so she doesn't wake up, she carefully picked up Sunflower so she didn't wake her lovely Twilight. She began to smile evilly as she teleported herself and the mare into a secluded room below Canterlot castle which only she knew how to get to, not even Luna knows how to get to this room.

The rooms size was average with no windows and one metal door. A chair sat in the middle of the room with a single light source hanging right above it. The rest of the room was dark. Celestia put Sunflower in the chair and put restraints on her front and back hoofs so she couldn't move. Once she was secured to the chair Celestia slapped her with a hoof to wake her up.

Sunflower woke up slowly her vision blurred after just being woken up. She looked around taking in her surroundings as she thought about where she was.

"W-where am I. Twilight are you there?" Sunflower called out to the darkness.

She heard the sound of hoof steps in front of her and who she saw in front of her was burned in her mind. There in front of her stood Princess Celestia in all her glory. The smile on her face was so maniacal. The smile she wore could even rival Jeff the killers cheshire smile because it was so wide. The smile alone sent shivers up and down Sunflowers body.

Celestia began to speak but the tone was not the same as it always was, it was much more evil and sinister. "Your in my private room deep below Canterlot." She said

"W-w-why am I h-here." Sunflower was beyond terrified she was barely able to get a sentence out because of scared she was.

"Why?, WHY!, it's because you stole my Twilight, she was supposed to me mine and I intend to make her mine!" Celestia's rage was back and at full force. "And all I have to do is get rid of you."

This time it was Sunflowers turn to get angry. "Stole, I didn't steal Twilight from you, she choose to be with me and I lo-"

Sunflower was cut off by a flash of light and a large gash appeared on her left hoof. Blood started coming out of the gash and dripped on the floor.

Celestia's magic died down and she smiled her maniacal smile "You will be silent, little pony."

Celestia walked back into the darkness and the sound of metal could be heard. She walked back into the light and in her magic was a scalpel sharpened to the point. She walked up to Sunflower and placed her hoof on Sunflowers gash and pressed down. More blood came out of the gash as Sunflower winced in pain doing her best not to scream.

Celestia just kept her sinister smile and whispered in Sunflowers ear with a voice so evil and sinister it caused Sunflowers eyes to widen in shear terror "Does it hurt, I hope it does" Celestia backed away from Sunflowers face "Now why don't we have some fun" She levitated the scalpel in front of Sunflowers face "Shall we."

She took the scalpel and stabbed Sunflowers right hoof causing a yelp from her as blood came out of the wound.

"Stop!, please." Sunflower begged

"Stop?, why would I stop, we've only just begun." Celestia's tone changed to just pure insanity.

Celestia took the scalpel and began to slowly and painfully cut away at Sunflowers flesh. Bit by bit, chunk by chunk, Celestia cut away at the flesh. As Celestia cut the flesh with her scalpel, all she did was smile and hum a little song. Each piece that she cut off hit the pool of blood that was below her body with a disgusting splash. Sunflowers screams of pain were heard by no-one. Tears fell from her eyes and hit the floor, mixing with the blood. Celestia jabbed the scalpel into what remained of Sunflowers hoof earning her a scream from the pony.

"On to the other ones now." She said calmly.

Celestia took the scalpel out of Sunflowers hoof and stabbed her back left hoof and then her right. She repeated this about ten times to each hoof. She took the scalpel and began to cut away at the flesh. Blood spurted out and hit Celestia's cheek. Smiling, Celestia licked the blood off her cheek and continued cutting until there was almost nothing left. Sunflower was crying, begging and pleading for her stop. But her only response was a knife to her chest. More and more blood came out of her wounds and onto the floor making the large pool of blood increase in size.

Celestia sighed with disappointment "This just isn't enough, I need something bigger to do the job." Celestia walking back into the darkness and came back moments later with a cleaver in her magic "This should do it."

Sunflowers eyes widened with fear "I'm going to die."

Celestia wasted no time she went straight for it this time. The cleaver came slamming down in Sunflowers right hoof causing her bone to break with a sickening crunch as blood sprayed out but she kept cleaving until the leg came off hitting the ground with a thud.

"AHHHHHHHHHH." Sunflower was bawling her eyes out begging for Celestia to stop.

"Keep screaming, no one can hear you when we are 100 feet below Canterlot and the walls are magically enchanted with sound silencing spells of my own design." Celestia leaned in and whispered in Sunflowers ear. "In other words, scream all you like. No-one can or will ever hear you."

Celestia began to laugh maniacally as she swung the cleaver into Sunflowers left hoof this time and went straight through, a clean cut with the leg coming off and hitting the floor. Blood spurted out of the wound almost getting Celestia.

"AHHHHHHHHHHH." The pain from her injuries was to great and she already lost alot of blood, so she passed out from the blood loss and pain.

"Awww, she passed out, well we can't have that, i'm done yet." Celestia used her magic and jabbed a needle with adrenaline into Sunflower causing her to wake up to feel the pain once again. "Can't have you falling asleep on me now can I."

Sunflowers voice was weak but she was still able to speak "Why are you doing this to me?"

Celestia was getting annoyed "Do I need to repeat what I said." Celestia closed her eyes and placed a hoof on her forehead out of annoyance then opened them again "It's because you stole Twilight away from me."

"But I didn't steal her away, I love her, I love Twilight with all my heart." Sunflower was crying again, not from the pain, but from realizing that she will leave Twilight.

Celestia's eye twitched with anger as she was getting frustrated with her and she finally snapped going in a blind rage. She took the cleaver in her magic and swung wildly at Sunflower, the sound of flesh being sliced and slashed could be heard with each swing of the cleaver. Celestia was hacking chunks and pieces of her flesh off, blood splattered everywhere, some of it splashed on Celestia, the rest went flying on the walls, on the ceiling, and on the floor covering the place in it.

As Sunflower was about to die she thought about one last thing that broke her heart 'I'm sorry Twilight that I have to leave you alone like this. Please forgive me. I love you.' A final tear came down her face as she let out her final breath.

After 10 minutes Celestia finally stopped swinging and dropped the cleaver on the floor with a loud clang. She looked at what she did to Sunflower. Her chest completely ripped open with her guts and intestines spewed out on the floor, pieces of her body were littered everywhere in the room, her face unrecognizable, and her jaw completely cut off.

Celestia just stared at what she did with a blank emotionless face until she started to laugh uncontrollably

"AAAHAHAHAHAHA I did it AHAHA now Twilight AHAHAHA will be all mine AHAHA and only mine." Celestia's maniacal laughter rang throughout the room. She laughed for a solid 3 minutes before calming down to take a breath. But then she thought about what she was going to do to cover this up.

Celestia rose a hoof to her blood splattered chin a rubbed it thinking about what she was going to "What am going to do, what am I going to do" then it hit her "I know exactly what to do."

Celestia teleported out of the room and to her personal chambers to wash the blood off her self. Once she was finished cleaning herself she made her over to her desk and used her magic to summon a random photo. She then used an illusion spell that only she knew and turned the existing photo into a picture of Sunflower having sex with a stallion. She knew that Twilight could detect magic but this illusion spell was of Celestia's creation it turned what ever you wanted into something else and it leaves no magical residew, so the spell becomes undetectable like it was never used in the first place.

"With this photo I can convence Twilight that Sunflower cheated on her with this stallion and when I was showed this picture I banished her from Equestria."

Satisfied with her little story she placed the photo in a secret compartment in the desk where no one will find it. She walked up to her bed and flopped on it wrapping herself in her blanket but just before she fell asleep she whispered one last thing to herself.

"Soon Twilight, you will be all mine and mine alone."
