I can make a normal scenario of Keaton if anyone wants that. And, also I hope you guys enjoyed this because this was my very first Yandere one shot. So... carry on

'Where's that treasure of mine at...?'

Keaton looked around for you as he was sniffing you out. Keaton has grown an attachment to you... a little unhealthy attachment.

If he couldn't find you he would sneak into your private quarters, sniff your clothes, and hoped by following the scent he would find you alone... only with him.

Keaton's nose finally picked up your scent as he perk up his ears and ran towards the scent. He ran up to it until he stopped dead in his tracks.

You were petting Kaden. His fluffy tail was wagging as you petted his ears.

"Ahh, (y/n)~ I love it when you groom me~"

You giggled as you petted them some more. "It's hard not to touch your ear when their so fluffy!"

Keaton's throat let out a growl as he quietly backed away. His inner werewolf was mad that his mate was being taken from him.

Keaton didn't see, but backup into bones of remains of bear skeleton, stripped down for meat and fur.

Just then, that's when it hit Keaton of what he should do...

Keaton sharpened one of his bones from human remains as he was going to get back his treasure.

He found Kaden asleep outside the castle, but nearby as he slept under a tree. The fox spirit hum quietly in his sleep as Keaton eyes glowed with anger as he quickly stabbed at the fox.

Kaden woke up, yelping and whimpering in pain as his blood could be seen in the dark night. Keaton stabbed him through the chest and near his heart as Kaden was losing a lot of blood.

"W-why...? K-Keaton...?" The fox said weakly as his throat cracked.

"You took my treasure! She's my greatest treasure of all~ SO I WANT HER FOR MYSELF!!!"

Keaton lunged at the fox as he stabbed him through the chest so many times...

Keaton laughed darkly as he thought of everyone... and they all should die...

Keaton was covered in blood. Done murdering everyone in their sleep by the time he came up to you.

You opened the door and screamed at seeing Keaton in blood.

"K-Keaton?! I know you hunt, but you're covered in blood more than usual!"

"Don't you love the scent of everyone you loved dead~?"

Fear took over as tears spilled down your cheek as you could imagine them dead... everyone...

"W-why...? WHY?!"

You lunged at Keaton as he dodged in time and grabbed your arm twisting it behind your back.

"Why? Because they took away the love I had for you!" Keaton reached down and kissed the nape of your neck as it send shivers down your spine. "Now I have my greatest treasure of all to me and only me~"

You screamed, kicked, and punched at Keaton to let you go. Keaton growled as he raised his hand. "SHUT UP AND LOVE ME!"

A hard smack to the head knocked you out as darkness took over...

Groaning in pain, you woke up to Keaton kissing your neck lightly as you were tied to a bed with rope.

Fear rose inside you as you started to shake the ropes in hope to get loose. Keaton growled as he tightly tighten the ropes.

"You're not getting away from me sweetheart~ You're staying with me~"

Tears flow down your cheeks as you looked up at Keaton with pleading eyes. "K-Keaton... s-stop! I don't want this! I don't love you!"

Keaton growled as he bite your neck hard, hard enough to make a mark as you screamed in quick pain at the burning feeling of his werewolf teeth biting your neck.

"But I've marked you as my mate~ so that means~" His hand rubbed your thighs up and down. "We can start a family~ I wouldn't mind my treasure having a litter of children~"

Sobs escaped you as a headache started to form inside your head. "K-Keaton... n-no..."

Keaton smirked as he looked at your body with hunger. "Oh yes my sweet treasure~ you better get ready now~"

Keaton kissed you as he pinned you down with his body weight. You screamed and cried as you knew you couldn't do anything but cry...
