Yandere Simulator One Shots (Completed)

68: My Inner Markings

This suggestion is from PrincessElina1 . It's a continuation of 'Marking You To Be Mine' and 'Bound To My Markings', so go ahead and read those one shots first. They both focus on Inkyu Basu and Sho Kunin, while this one shot focuses on Sakyu Basu and the person I ship her with thanks to tumblr.

Succubus! Sakyu Basu x Oka Ruto:

Sakyu, Inkyu and Sho walked home from the school, with Sakyu still carrying Oka. Her body was weak, and she was fading in and out of consciousness after Sho had bitten her. The streets were still dark, but the sun was going to start rising soon. They reached Oka's house, while Inkyu and Sho continued walking, Sakyu stopped to drop Oka off. She looked at the girl in her arms, and realised she was unconscious again. Sakyu sighed, placing a small kiss on Oka's forehead. Sakyu had feelings for the small occult club president, but never showed her. She banged on the door several times, waiting for someone to answer. Nobody did. Eventually, Sakyu decided to just leave Oka unconscious on her doorstep. She didn't feel good about it, but she had to go home before the sunrise. Someone would answer the door soon, right? She knocked several more times as loud as she could before running away.

A week later, Sakyu was relieved to see Oka at school again. They were both on the school rooftop, with the only other people being Kuu Dere, Midori Gurin and Mai Waifu. She hadn't been in, and Sakyu worried for her, even if she didn't show it. She walked over to her, and it became evident she wasn't 100% ok. She was clearly weaker, and looked a little skinnier and paler than usual.
"Can I talk to you in private?" She asked. Oka's eyes widened a little as she nodded her head. They both walked to a more secluded area to talk. "How you feeling?" She asked, looking at her arm which was covered by her usual grey spider web gloves.
"G-good." She lied, not making eye contact. She wasn't feeling too good. Her body was weaker, and she fell over every hour or so. She sometimes even passed out for a few minutes.
"I'm glad to hear. D-don't get the wrong idea. It's not like I care." She suddenly snapped, feeling her tsundere side coming out. Oka looked at her a little confused. "Ok fine. I kinda care, b-but not like that!" She snapped again, still confusing Oka. A small tear filled her eye. "A-are you crying? Don't cry, Baka!" Sakyu snapped, a little upset. She wasn't upset with Oka, she was upset with herself for not being able to confess to her.
"W-what do you mean?" Oka asked, her voice shaky and confused. One small tear ran down her eye. Sakyu brushed it away with her hand, blushing slightly.
"Ugh." Sakyu groaned loudly, crashing her lips into Oka's. She was surprised, but hesitantly kissed back. Sakyu broke off the kiss, blushing madly. "I love you Oka, ok?" She said loudly, still a little tsundere. Oka began to blush also. "Will you be my girlfriend?" Sakyu asked. The blush on their cheeks deepened as Oka nodded her head.

The next day, Oka had to walk past the incinerator where the delinquents usually go to skip class. She kept her head down, knowing they would come for her if she looked up at them. That didn't stop them. A couple of female delinquents walked over to her, smirking at each other.
"Hey occult club weirdo." One of them smirked, grabbing her choker and pulling her up from the ground. She gulped, her weakened body shaking. The delinquents laughed as the choker snapped. She crashed to the floor as they continued laughing. That was the moment the demon was unleashed. Oka looked back up at the delinquents, her usually violet eyes now pitch black. She laughed evilly, standing up.
"You cannot hurt what is already broken." She growled threateningly, before launching an attack on the delinquents.

When Oka didn't come to meet her before school, Sakyu started to become concerned. She walked around the school in search of her new girlfriend. As she went outside she saw something shining in the grass. She knelt down, and saw the object shining at her was the sunlight reflecting off of the charm on Oka's choker. Sakyu had never seen her without it, neither had anyone else. She decided to take it to the occult club, have it examined. She got strange vibes from the choker, and needed to know why. She picked it up and put it in her pocket, before walking away.

Inside the occult club was Shin. He was by himself reading a book. The door slammed open as Sakyu walked in, her hand tightly grasping Oka's choker.
"Hello Sakyu." He looked up from his book and smiled at her, before noticing Oka's choker. "Oh, god. Why do you have that?" He stood up, put his book down and walked over to Sakyu, taking hold of the choker. The shock and worry was evident, making Sakyu concerned.
"What's wrong, Shin?" Sakyu asked.
"You don't know, do you?" He asked quietly, trying to remain calm. Sakyu shook her head as she let go of the choker and giving it to Shin. He walked to a bookshelf and began to search for something. Once he had found it, both he and Sakyu sat down on the floor in the centre of the rug. "Oka's parents used to be occult enthusiasts, just like her. When she was 3 years old, they attempted to summon a demon. They succeeded, and it possessed Oka. The only way to control it was with the choker, as they were unable to perform an exorcism. The demon has been known as Inner-Oka, and had never come out until now." He took a deep breath as he continued looking through the book, trying to find the page.
"How do you know this?" She asked calmly. Shin didn't look up from the book, but heard what she said.
"We grew up together. Her parents told me this before they stopped caring." He sighed a little as the memory came back to him. "They used to care so much about her. They did anything they could to try and help their daughter, but there wasn't anything they could do. They gave up on her. When she was 12, they abandoned her. They moved to a new city thousands of miles away and started new lives, forgetting about their daughter. She never knew about what happened to her when she was 3. She never knew the reason why they abandoned her." Sakyu felt his words pulling harshly at her heartstrings. She felt awful for her girlfriend. She lightly brushed away the tears in her eyes, controlling the desperate urge to go find Oka and suffocate her in a hug.
"We have to help." Sakyu said. Shin sighed and opened the page so Sakyu could also see it.
"We can't perform an exorcism on her. It's impossible. What we can do is enchant the choker to contain the demon. Her parents taught me how incase a situation like this occurred. The choker was originally enchanted, but it broke as soon as the choker came off." He started, pointing out different diagrams to Sakyu as he spoke. "We need to get her in here without anyone else, and keep her in here until night. The enchantment will only work then." Sakyu nodded her head, forming a plan in her mind.

Sakyu, Inkyu and Sho left the occult club, each of them clear on their part of Shin and Sakyu's plan. Sho would distract the nurse while Inkyu stole the tranquilliser. Meanwhile Sakyu would lure Inner-Oka into the occult club and keep her there until Inkyu brought in the tranquilliser. Sakyu sprinted around the empty hallways, as everyone else had gone to class. She eventually found Inner-Oka. She shared a body with the normal Oka, but they were not the same person. Inner-Oka twitched insanely while she walked, and her eyes were black and soulless.
"Hey Oka." Sakyu said casually. Inner-Oka twitched again as she started walking towards Sakyu. If looks could kill, the Basu sister would've died 100 times already. She walked backwards, keeping an eye on Inner-Oka as she kept walking towards her. The sisters both reached the club room at the same time. Inkyu passed the tranquilliser to Shin, while Sakyu and Sho restrained her in the room. Shin injected the tranquilliser into her neck as Inkyu closed and locked the doors. Inner-Oka passed out within minutes.

Shin held the book and the choker, waiting for the tranquilliser to wear off. Inkyu and Sho were sat beside her, ready to restrain her. He looked at Sakyu, seeing her concern.
"Sakyu, before I perform the enchantment, I need to warn you of something." He said. She looked over at him with a raised eyebrow. She was confused, but she didn't say anything. "She might lose all her memories when I contain the demon." He warned as Sakyu looked down at Oka.
"It's worth the risk." She said instantly. None of them wanted Inner-Oka, and her losing her memories was only a small price to pay. Shin silently nodded his head, turning his attention back to Inner-Oka as the tranquilliser wore off. Sho and Inkyu tacked her, restraining her on the floor before she could fight back. Shin performed the enchantment, before passing the choker to Sakyu.
"Sakyu, you need to put this on her." He instructed. "The person who loves her the most needs to do it, and I can tell that's you." She nodded her head, getting down on to her knees beside Inner-Oka.
"I love you, Oka." She murmured, placing the choker back on her girlfriend. Her eyes closed, and when they reopened a minute later, they were back to normal. She looked at the people surrounding her with a nervous and almost scared face before she asked a question that shattered Sakyu's heart.
"W-who are you?"
