It All Started By One Single Tear (Rantaro x reader x YandereMastermind Kokichi)

Chapter 4 Part 9: Korekiyo's Motive

Your POV:

"My sister... and I... were lovers," Kiyo explained with an insane look on his face, "but many people called this love, a forbidden love..."

Those words were the only words used by Kiyo to describe his sister. His eyes seemed to be swirling with darkness, showing many traces of his original eye color. The look of insanity on his face was enough to send shivers down my spine, but I was also confused.
Kiyo and his sister were lovers according to him, and it was causing a dreadful feeling to enter my soul. It made sense to be able to love family members, but that type of love wasn't romantic. For some reason, hearing Kiyo call his sister his lover made me instantly think of romantic...
    "Are you telling us that you were in a romantic relationship with your sister?" Rantaro asked with a confused, yet serious expression.
     "Kehehe... It is not that difficult," Kiyo replied with a laugh, "my sister is my lover."
     I was silent at that point still. I was instantly regretting my decision on coming here. I knew for a fact that if Kiyo wasn't tied up, he would've tried to kill me... I was terrified, and now I was even more confused. He told us that his sister is his lover... not was. I had no idea what he meant by that, and part of me didn't really want to know.
    "Would you mind sharing your reasoning with the class?" Kokichi asked with a small smirk.
     "Kokichi, please be serious..." Rantaro replied with a sigh.
    "I am being serious though," Kokichi replied with a smile.
    I let out a small sigh. This wasn't the time to be getting into some sort of argument. I had no idea if Kokichi was making his phrasing more jokingly to help ease my mind slightly or if he was doing it to mess with everyone. No matter what his reasoning was, I felt like Kokichi had some sort of ulterior motive behind wanting me to bring Kiyo his meal, and I had no idea what that ulterior motive would be.
    "I'll act more serious because Rantaro obviously no fun," Kokichi explained as he rested his arms behind his back, "so Kiyo, what do mean by your sister being your lover...?"
    It seemed when Kokichi said that, I instantly looked at Rantaro. He seemed to an annoyed expression on his face, seeming to face palm in response to Kokichi. I instantly placed my free hand on his arm with a nervous expression on my face. My other hand was still balancing the tray I had with the food items for Kiyo. I knew that I was quiet right now, but I knew Rantaro was getting frustrated with Kokichi. I wanted to ease his mind if only a little.
    "R-Rantaro, it's going to be okay," I told him with a quieter tone.
     Rantaro seemed to look down at me, smiling a little bit. I felt him place his hand on my head and ruffle my hair slightly. I blushed lightly, but almost instantly I felt some of my anxiety melt away. I looked up at him, smiling at him.
     "Thank you, (y/n)," Rantaro said with a smile, "I feel a bit better now..."
     "It's no problem," I replied, "I think we're all on edge right now, so all we need to do is stay calm..."
     "Well said, my beloved!" Kokichi exclaimed, "so Kiyo, please explain now..."
      Kiyo seemed to be silent, seemingly looking annoyed by what was going on right now. I could see why. Being asked to explain something before an argument starts to take form would be very annoying to a lot of people. We had to focus, and while I was uncomfortable in this situation, I was the one who ultimately decided to be here.
     "To put it in terms that you all would understand, I loved my sister deeply... and she loved me deeply," Kiyo explained, "the fact that we were siblings...meant nothing to us. They called it "forbidden love," but none could stop the love we shared... Ooh... How I long for my sister's warmth..."
     When Kiyo explained this, I felt that same sense of dread. It was at that point that I realized that the relationship was a romantic and sexual relationship. I was shocked about that fact, and I didn't even know what to say in response to what Kiyo said.
     I felt like that this would also have an affect on Rantaro as well... he was looking for his sisters and he must've felt very uncomfortable when Kiyo explained his relationship with his sister. I somehow felt like something was missing in his explanation though. He talked about sending me to join her. That could mean something that would be sad for him, and also terrifying.
"The only time I felt at peace...was when I was enveloped in my sister's warmth!" Kiyo exclaimed, "I bet you all are still wondering why I wanted to kill... why I attacked Angie... why I decided that I wanted to kill (y/n)... well that reason is just a simple one..."
I could feel beads of sweat forming on my face when I heard Kiyo say that. The way he was talking... when he was talking, I could hear his tone get darker and darker. From what he told us about wanting me to join his sister... from what he said about not trying to kill me, but wanting to kill me... I knew right then that there was more than one reason why he attacked me specifically. It wasn't just because I confronted him about his plan.
"W-Why did you attack Angie...?" I asked, "what was your other reason for trying to kill me...?"
My tone was shaky when I asked that. I was trembling slightly when I was talking. I was nervous... part of me didn't want to know his motive for trying to kill, but... I needed to know why... I was traumatized, yet I was flung into this situation because Kokichi wanted to find out why Kiyo tried to attack Angie as well as myself. I still had a feeling that there was another reason by it... sadly, I still didn't know what that motive was.
     "To answer your question, no it wasn't because I wanted to escape from this school," Kiyo explained, "It was because... I had to— I had to kill for her... but sadly my ploy was ruined..."
     As soon as those words left Kiyo's mouth, my blood went ice cold. The way he was speaking... the look in his eyes as he spoke... there was no form of hesitation in his voice. Kiyo's words were the truth... His reason for trying to kill me was not only because I confronted him... it was because he wanted to kill me for his sister... the thought of it sent shivers down my spine... and I felt like I was frozen in shock...
    "W-What?" Rantaro asked in response, "you're telling me that your justification on attempted murder was for your sister!?"
     I noticed that Rantaro was starting to get irritated. I could tell from the tone of his voice. It was similar to how Rantaro acted when he found out that Angie attempted to murder me. It was obvious that Rantaro was very protective over me, but I knew for a fact that we had to try and stay calm. I wasn't the only one who was affected by what happened. Rantaro was too, and it made me feel awful that I didn't notice it until now...
     "My sister was very sickly, you see..." Kiyo explained in response to what Rantaro said, "she was always in and out of the hospital ever since she was a child. It was because of that that she didn't have many friends. She always seemed so lonely..."
     The story Kiyo was telling. Explaining the fact that his sister was sick... this made my thought on the motive for killing even stronger. Chances were, his sister passed away from a condition she had. I felt sad by this, because it was always rough to lose family... as much as I thought it was not normal to be in a relationship like that with his sister, it was cruel to lose family.
(FYI, reader is the type not to judge others, so I found this chapter very difficult to write)
     "Even if I could be her little brother and her lover, I couldn't be her friend," Kiyo explained, "so, I thought I'd find her some friends. Friends for my dear deceased sister."
      This was what confirmed my thoughts... Kiyo's sister was dead, and chances were, what Kiyo meant by finding his sister friends.... was killing people to have them join his sister. I felt a dreadful feeling well up inside of me. It was a feeling of sickness that washed up over me when the thoughts made their way home into my heart...
     "By that silence, (y/n), I think you understand what my plan was..." Kiyo said, seeming to note my expression, "my sister is now a ghost, so her friends should be ghosts, too, right? For Sister's sake...I've killed many! To send her 100 friends!"
I was even more shocked after hearing this. The shock on finding out that he was his sister's lover... the shock that he attempted to kill Angie and I for his sister... the shock that his goal was to kill one hundred people for his sister.
My mind drifted to our goal in the beginning. That goal was to escape together... to be friends when we got out of this mess... I was able to help many people to realize that killing was never the answer... but now... those thoughts were being conflicted...
    "They were all wonderful people! Worthy of being Sister's friends!" Kiyo exclaimed.
"Instead of killing people for your sister, couldn't you have the people you chose use a pendulum to contact her?" Kokichi asked in a seemingly joking way.
"Kokichi, this is already frustrating to try to get a grasp on," Rantaro muttered with a sigh, "you aren't exactly helping..."
"I'm being serious though... there are ways to contact the dead aside from killing off random people!" Kokichi exclaimed, "I'm trying to give ways that will prevent murders!"
"Your words mean nothing,"Kiyo explained, "kehehe... all that matters was that Sister was very happy."
It seemed that something happened after Kiyo said that. His mask suddenly went down his face as if some sort of I know force lead this to happen. It was chilling to me because Kiyo obviously couldn't do anything to remove his mask. He was handcuffed, and his legs were tied as well.
This was actually the first time I've seen his full face though, but it was slightly chilling to me to see his actual face. Kiyo had bright red lipstick on his lips, making him have more of a feminine look to him, and his eyes seemed to have more defined lashes as well.
"Yes, Korekiyo... I am very happy," Kiyo spoke, his voice seeming to be lighter than it was before, "thanks to you, I am not lonely."
Kiyo's voice was a lot lighter than it was before. It was almost as if his voice was more feminine than it just was. I could feel myself stiffen up slightly from the shock of the whole situation. I turned my head slowly over to where Rantaro and Kokichi were standing. They both had similar expressions to me, and it was shocking to see Kokichi was actually taken aback by something. It seemed that the two were too shocked to say something, so I knew I had to.
"A-Are you?" I stuttered nervously.
"I am Korekiyo's older sister. It's very nice to meet you (y/n)," Korekiyo said in a lighter voice, "I was hoping I could be friends with you, but it didn't happen... either way, I would like to thank you and the others for looking after my younger brother."
     I was staring at Kiyo with a shocked look on my face. Thoughts raced through my mind because I was wondering what was going on at this point. It was like that Kiyo showing his face, wearing the bright red lipstick was his sister. That version of Kiyo was his sister, and I had no idea how that was possible. It was mind boggling...
     The thing that was in my mind now was the hypothesis that his sister's spirit was somehow possessing his body. It was both very shocking and confusing to me that this was even happening. I felt a slight wave of nausea come over me, and I staggered slightly.
     "You look like you aren't feeling well," the lighter voiced Kiyo said, "what's wrong? My younger brother told me about how you wanted to be friends with everyone once you all managed to escape this school. Would you be willing to accept my younger brother and myself the way we are? If so, then we can be friends, and you can keep your life...."
    "Why would you ask her that?" Rantaro asked, "do you have any idea how traumatized (y/n) is from what you did yesterday?"
    I looked over at Rantaro in response to that. Many thoughts were swirling around in my head as this happened. I was questioning myself. I didn't want to judge anyone negativity... It was chilling that the only way my life would be guaranteed would be if I accepted this. I was wondering how I could accept it when I was traumatized... I couldn't think straight about the conversation going on.
     With the way I was right now... I couldn't focus. Each time Kiyo spoke about planning to murder me, the images would enter my eyes... feeling the cold metal of the sickle against my neck... feeling the blade cut into my skin. I couldn't think straight.
      It was a miracle that I wasn't on my knees and crying from this situation. I looked over to Kokichi who seemed to be staring at me, seemingly waiting for a response. For some reason, the way he was staring at me brought chills down my spine, and it made me wonder again why he asked me to do this.
     If Kokichi knew how this affected me, why would he do this... was he trying to make me suffer...? What was his gain from putting me through this. The room was dead silent, and I felt my anxiety welling up in my chest.
     Kokichi and Kiyo were both staring at me, waiting for an answer. My heart beat started fo beat faster, causing me to start to hyperventilate... I could feel myself starting to gasp for air. With a rush of energy, I set the tray down on the counter of the prison bathroom.
    My hand clenched the fabric of my outfit as I sped to the exit of the bathroom of a Ryoma's Lab. I was trembling as I was trying to keep air going into my lungs, and with each breath... it got harder.
"I need time to think..."
    Those were the words that left my mouth before I left the room. The tone of my voice was dry, yet panicked... I knew for a fact that when Kokichi said I was going to be okay... I wasn't going to be okay... I needed to at least be able to think clearly before I could make a decision... that was the truth of the situation.
