The liars sister (Oumasai/Saiouma)(Rantaro x Reader)

Chapter 1

(Y/N)'s POV
Well, a black and white bear named Monokuma explained everything about the game and everyone was obviously against it. I couldn't believe it. Why was this happening to us? We decided to introduce ourselves to each other. But before that, Kokichi pulled me aside and gave me a quick hug so the others wouldn't see. "Ko, what do you need?" I said quietly. Ko was the nickname I gave to Kokichi. "We need to hide that we are siblings. If anyone wants to kill me or you then they'd easily be able to use the other one." I could tell he was just wanted to be careful so I agreed. "I'll say my last name is (L/N)." He nodded, then put his mask on (not literal) then left to got introduce himself to the others.

I saw a plain looking girl with long blue hair and glasses, so I went to introduce myself to her. "Hi. I'm (Y/N) (L/N), the Ultimate Fashion Designer." I said. "I'm Tsumugi Shirogane, the Ultimate Cosplayer." She introduced herself. I've always thought it was can make themselves look like fictional characters. "Oh really?" I said. "What's your favorite character to do?" "Hm. I don't know. I really like Hinata and Kiyoko from Haikyuu but I also like Toga, Jiro and Todoroki from My Hero Academia. I also like Sailor Mars, Sailor Jupiter, and Sailor Moon from Sailor moon. Oh sorry. I went off and started talking about it all." Tsumugi said. "Don't worry. I love those shows too." I said. "Really? I don't find many people who like the same things as me. We should probably go talk to other people. Let's talk more another time." She said with sparky eyes and walked away to talk to others.

"Excuse me." I heard a male voice. When I turned around, I saw mine and Kokichi's best friend, Rantaro Amami. "Hey, Rantaro! It's been awhile!" I wrapped my hands around his neck, hugged him, and a light pink blush spread across my face. I've had a crush on him for a while. He moved away about a year and a half ago. We didn't text much because he had to take care of his twelve sisters. "Um....Do I know you?" He asked in a confused voice.

"W-what do you mean? O-of course you know me!" I stuttered a bit. I thought this was just another one of his stupid pranks that he did with Kokichi. "Ok, ok. Stop joking. You can't fool me. Did Kokichi tell you to do this?" I asked. "Who's Kokichi? Is he here? I haven't met anyone with that name." He said, even more confused. I decided to just lie. He shouldn't be able to tell, as I was as good at lying as Kokichi was. "Oh sorry. I must've gotten you confused for someone else." I lied. "It's alright. I'm Rantaro Amami. I can't remember my Ultimate talent, but I'm not suspicious, I swear." He introduced himself. "I'm (Y/N) (L/N), the Ultimate Fashion Designer." I also introduced myself. It hurt that he didn't know who I was but I had to act fine. "Did you design your own clothes?" He asked. I wasn't surprised as I usually get asked that when I say what my Ultimate is. "Yea, I did. I replied.

Then we went our separate ways and I introduced myself to everyone else. Maki was suspicious to me because she lied about her Ultimate Talent. 'Ultimate child care giver' my ass. With the way she looks she could be the Ultimate Assassin or something.

After introductions, we explored the rest of the school and it took all day. We went to the dorms to get some rest and the next day we tried escaping through the sewers but it didn't work. When Kaede tried to get us to try more, Kokichi spoke up and told her that we couldn't, that we were too exhausted, and that it was just torture that she wouldn't let us stop.

I bet me and Kokichi were, at least, a bit more tired. Being twins we could feel each other's pain but it wasn't exactly how the one who got it, felt it. For example, if Kokichi started bleeding from the head and he was feeling really dizzy, I would be kinda dizzy, as for that part of his head that was bleeding, that part of my head would be a bit numb. If I got cut on my finger, he would be a little numb on that part of his finger. We found this out at an early age, as we had abusive parents. And we're almost always bullied in school. We had a group of friends called D.I.C.E. and other than that, we only had Rantaro. The outfits and Masks that everyone wore, were made by me. I also had an outfit, as vice leader, but now I'm probably not putting it on as much because of everyone here. Around 30 minutes after the night time announcement, I heard a knock at my door.
