73: You Now Will Be His Ex Girlfriend

Suggested by PrincessElina1

Yandere! Amai Odayaka x Riku Soma:

Amai sat in her club room with Ayano looking out the window at her crush Riku Soma. Ayano smirked at her, knowing what it felt like. She remembered staring dreamily at her Senpai before she won his heart. She still stared at him dreamily now.
"Are you in love with Riku, Amai?" Ayano asked, not getting Amai's attention. She nodded her head.
"Yeah, but he never notices me." She sighed, not looking at Ayano. The dark haired girl nodded her head slowly.
"If you want my advice, I suggest you eliminate anyone who tries to take him from you." Ayano smirked. That's how she had won Taro's heart. Amai thought about it, before nodding her head.
"Ok." She had a bad feeling, but it wouldn't matter if Riku was hers in the end.

She sat in her club room waiting for Kokona. She looked outside the door and saw Kokona and Kizana talking to Riku. She felt her blood boil, but didn't let it show. By the time Kokona walked into the club room, Amai already had a plan formed in her mind to eliminate both purple haired girls.
"Hey Kokona. Would you mind making octodogs?" Amai asked sweetly. Kokona nodded her head and started cutting them. Amai put on a latex glove, before putting in an oven mitt as she watched Kokona. She was also wearing an apron over her school uniform. Once she was done with the knife, Amai picked it up out of the club members' sight.

She walked into the drama club, and saw the only person inside was Kizana. Amai smirked. Perfect. She walked up to Kizana silently.
"Surprise." Amai hissed, covering Kizana's mouth with one hand before stabbing Kizana in the stomach. She allowed her body to drop to the floor before she continued stabbing Kizana. She left the knife in her skull once she was dead, which had Kokona's fingerprints on it. She took off the bloody apron and left to burn it in the incinerator before she was caught.

"I didn't do it, I swear." Kokona sobbed as she was arrested by the police. They had been called after someone discovered Kizana's body. The police found Kokona's fingerprints on the murder weapon, and assumed she'd done it. Nobody even suspected Amai.
"I know you did it." She heard a whisper in her ear. She turned around in shock, and was relieved to see Ayano stood behind her, laughing. "I didn't think you would."
"Well, I did. And I would happily do it again if it means I get to be with Riku-Senpai." Amai smiled evilly at Ayano, before walking away.

"Thanks for inviting me to the occult club, Oka." Amai heard a familiar voice outside her door. She looked outside and saw Oka and Riku walking to the occult club. The blush was evident on Oka's pale face. Amai didn't say anything as she closed the door and formed a plan. She made a small batch of chocolate cupcakes, dividing it into 6. She was planning to make cupcakes for all the members of the occult club. It wasn't suspicious, as she did occasionally made them treats. She looked around, and saw a large bag of peanuts. She took a handful and started to grind them into a fine powder. She knew Oka was severely allergic to peanuts. She also found a bottle of poison, which she stole from the chemistry lab incase she wanted to poison rivals. She tipped a quarter of the bottle into one of the bowls of cake mix along with the peanut powder. She mixed it until the consistency matched the others, before cooking the 6 cupcakes. She made sure to keep the poisoned one separate from the rest so she didn't accidentally poison any of the other club members.

"Hey guys. I made cupcakes." She said, coming into the room. She acted surprised to see Riku, but was genuinely surprised to see Cupa also in the club room. "I only made 6, as I didn't realise you were in here, Riku and Cupa. Sorry."
"That's fine. Don't worry about it." Riku smiled as Cupa nodded her head in agreement.
"Oh, I even iced your name's on them." Amai smiled to the club members as she passed them out. She had done this to make sure Oka received the correct one. Once the club members had theirs, she quickly left. She didn't want to be around when Oka was dying, as she assumed she would be accused of sabotaging the cupcakes.

"How are they?" Riku asked once Amai had left and the club had started eating. Most nodded their heads, showing they were good. The only person who didn't respond was Oka.
"Are you ok?" Cupa asked, looking at Oka. She had started having an allergic reaction to the peanut in her cupcake. "Oh my lord, she's choking." Cupa shouted as Oka fell to the floor. Panic filled the room as she only got worse. The poison was taking effect, and the allergic reaction was only making Oka suffer in her last moments.
"Someone phone an ambulance." Shin shouted, searching for Oka's medicine in her bag. Nobody knew she had been poisoned, as it looked like she was suffering an extreme reaction.
"Oka please don't die." Cupa shouted, her voice filled with despair. Her words did nothing, and Oka died seconds later. Cupa tightly held her hand as she sobbed. She couldn't believe Oka was dead. Riku pulled Oka's hand out of Cupa's, embracing the brown haired girl as she cried. "It's not fair." She cried. Riku nodded his head, holding her tight.
"I know. I know." He comforted her. Most of the club members had left the room to get help, leaving Cupa, Riku and Shin as the only people in the room with Oka's corpse. None of them knew Amai was watching them, hatred growing for Cupa. She hated how Riku comforted her. She hated when Riku kissed Cupa's forehead as she cried for Oka. She walked away, forming a plan on how to eliminate her hopefully last rival.

The next day, Amai waited in the cooking club for Cupa. She had left her a note in her locker, asking her to go there immediately. She had made a cookie laced with a crushed up sleeping pill. Cupa walked into the room, but she looked miserable.
"I heard what happened yesterday. I'm really sorry." Amai said, comfortingly. Cupa nodded her head, not looking up from the ground. "Here. I made you this." Amai offered her the cookie. Cupa made a soft smile that lasted a second as she took the cookie.
"Thank you." She murmured, biting into it. She passed out moments after finishing it.

When Cupa woke up, she was tied to a chair in the cooking club. Watching her was Amai. She silently walked to the stove, then returned seconds later, holding a large saucepan.
"I saw my Senpai kiss you. Senpai would never kiss you if you were hideous." Amai growled evilly, before she 'tripped over an imaginary pebble'. Inside the saucepan had been boiling, salty water, which was now all over Cupa. She screamed and cried in pain as the water scalded her body. Amai then took a knife and started stabbing Cupa. At the worst possible moment, Riku walked in.
"What are you doing Amai?" He shouted. She looked up at him, before standing up. She still kept the bloody knife in her hand.
"She was in the way." Amai tried to justify her actions. Riku stood back as he was hit with sudden realisation.
"You did it, didn't you?" He asked, trying to remain calm. "Kizana, Kokona, Oka, now Cupa." She slowly nodded her head as her body was consumed by an insane twitch. "You killed Kizana and framed Kokona for it. You made Oka food you knew she was allergic to. Didn't you?" He accused. He didn't need to ask about Cupa, as he'd seen Amai killing her. "I hate you for what you've done." He spat. She shook her head in disbelief as he went to leave. She charged at him, pinning him to the wall.
"If I can't have you," She started, losing control of her body. She brought a twitchy knife to his neck, twitching with her hand and body. "Then nobody can." She stabbed the knife into his neck, which killed him. She retracted the knife as soon as she realised what she had done. "Senpai. I'm so sorry." She apologised. Now she had no Senpai her life had no meaning. She stabbed herself in the neck, committing an unplanned murder-suicide. She died next to the one she loved, believing they would be together forever in heaven.
