152: Our Shadow Sister

The first of 5 suggestions from AnonymousWriter37

Sakyu Basu & Inkyu Basu & Oka Ruto:

Sakyu and Inkyu stood on the school rooftop like they usually did in the morning before class. They looked around, and saw Oka watching them. She usually did that, and they had gotten used to it. They knew she was looking for proof that they were supernatural beings. They looked back at each other and smirked.
"Are you watching us again, Oka?" Inkyu said as she and her sister turned their attention to Oka. She stepped out from behind the wall she'd previously been spying behind, her legs shaking slightly.
"I-I'm so s-sorry. P-please don't be m-mad." She stuttered quickly, embarrassed about being caught spying.
"Silly girl." Sakyu laughed as she walked over to her and put her arm over her shoulders. "You should just talk to us instead of spying on us." She told her. Oka looked at her, confused.
"Yeah. If you think we're supernaturals, why don't you just talk to us? You might find out more." Inkyu added, giggling. Oka nodded her head a little hesitantly as Sakyu lead her over to where they usually stood.
"S-so... a-are you s-supernatural?" Oka asked hesitantly. Sakyu and Inkyu looked at each other before laughing.
"Of course not. Only a fool would believe something like that." They said in unison. Oka made an awkward laugh, making the sisters laugh.
"You're an interesting one, Oka." Sakyu said, keeping her arm around Oka's shoulders. "Please tell me you'll hang out with us tomorrow."
"O-ok..." she managed to stutter through her confusion. This is the exact opposite of what she had expected. She'd been caught stalking the Basu sisters, something that would probably anger most people, but they were so kind to her.

They continued spending their mornings talking together. The sisters listened to Oka discuss her theories and helping her become more confident. They also listened to her talk about her newfound feelings for Taro Yamada, and her belief he had cast a hex on her. Most students though she was crazy, but the Basu sisters found her intriguing. Oka's reputation was taking a nosedive, but the sisters were still friends with her. They didn't care.
"I-I think I'm going to confess to T-Taro today." She admitted, blushing at his name.
"You should. He'd be crazy to reject you." Sakyu said a little excitedly while Inkyu smiled at her encouragingly.
"We'll help you with your confession if you want." Inkyu suggested, putting her arm over Oka's shoulders. The small girl nodded her head, nervous and excited for her confession. She only hoped she wouldn't be rejected.

The next few weeks, Oka stopped spending the time before class with the Basu sisters. They assumed she was spending time with Taro, as they assumed her confession had been accepted and they were dating now. They stood by the railing overlooking the courtyard, seeing Taro sat with Ayano. They were kissing, as they were now a couple.
"Where's Oka?" Inkyu asked, as they continued looking at Taro and Ayano. Sakyu shrugged her shoulders.
"I don't know. We should go find her." Sakyu suggested, taking hold of her sister's hand and leading her off the school roof. They were a little worried for Oka. She had been in school, but no one spoke to her and she hadn't spoken to anyone.

As they walked past the occult club, they could hear the faint sound of sobbing. Sakyu opened the door, and they found Oka sat in the middle of the rug with her back to the door. She was the only person in the room.
"Oka?" Inkyu asked hesitantly. She turned to look at Inkyu and Sakyu, and they instantly knew she had been the one sobbing. Tears stained her pale cheeks, and the sisters could see red bloody lines on her arms. The ritual knife sat beside her, the edge of the blade red with blood.
"What's wrong, sweetie?" Sakyu asked as she and Inkyu sat down beside Oka. The smaller girl shook slightly, more tears running out of her eyes.
"L-Leave me alone." She said sadly. The sisters looked at each other, confused. "I'm a d-demon." She sobbed softly to herself. The sisters put their arms around her at the same time.
"You're not a demon, Oka. Why are you so sad?" Sakyu asked softly. Oka shook more in the sister's arms as she made a small sob.
"E-everyone hates me." She cried sadly. Her reputation had taken a nosedive over the past few weeks, ever since she had stated she had feelings for Taro. Now almost everyone hated her to the point of wanting her to kill herself, even her club members didn't want to be around her unless they had to be.
"We don't hate you, Oka." Sakyu told her, gently stroking the back of her hair. The smaller girl shook her head, not believing them.
"Yeah, you're like a sister to us." Inkyu added, hugging her tighter. She didn't care her shoulder was starting to dampen with Oka's tears.
"D-don't talk to me anymore." She murmured, trying to push them away. "I don't want to bring both of your reputations down." Sakyu shook her head gently.
"I don't care about my reputation." She said softly. "I'd lose my reputation in a heartbeat if that meant I didn't lose you." Sakyu told her. Inkyu nodded her head in agreement.
"S-stop being so k-kind to me. I-I don't deserve it." Oka murmured. She felt completely broken after having been mercilessly bullied since her confession to Taro ended with him rejecting her harshly.
"Don't you dare talk like that." Inkyu told her a little angrily. She hated seeing Oka so depressed. "You're our little sister, don't listen to anyone else, because they're wrong." They had become close to Oka, and thought of her like a little sister.
"We love you, Oka." Sakyu said softly. The sisters stopped hugging her, wiping away her tears with their hands. "Were going to stick by you, regardless of what everyone else thinks."
