This is a bit of Kiibo X Reader. 

(y/n)'s POV

"I'm Ouma Kokichi. I'm the Ultimate Supreme Leader! Now could you open the door?" he asked.
"NO! I don't know anyone! I don't want anyone!" I shout back.
'Well, Hi! I'm the Ultimate Introvert. I don't like people and so leave me alone!' I kept on thinking on and on. I've got the key in my hands so he can't enter. Just don't come in. I want to be alone. 

The knocks slowly faded. There was no more of the banging and noises. I continued to play games with my piece of paper. Drew pictures of me being alone. Probably a day passed but I didn't sleep. Ouma, I think came back again. 

"Come OUT! It's me. I'm OUMA KOKICHI! Who are you? Tell me! Then I'll leave you for a while!" he shouted. 
For me that sounded like a good deal for me. 
"I'm (y/n) (l/n)! The Ultimate Introvert! Now if you tell them about me I'll... I'll kill you!" I shout back.
The door was silent for a while. Like he said. But then a mind was thinking of possible ideas.
'He might be telling the others. Or is he insulting me behind my back?' my mind thought over and over. Again and again. 
Curiosity took over me and I slowly opened the door. I was about to close the door but then I got tackled by a person.

"That was Lie~! Hello, you look beautiful!" Ouma said. 
His purple eyes and the blue hair was absolutely beautiful. I can't think that! I pushed him out the door and locked the door. 
"You know I've got the key so I can come in, right~!" his voice slurred. 

I checked my pockets. They were empty. 

"I promise to not tell anyone. Just let me come in! I'll bring grape Panta!" he said. 

Grape Panta? Is it here? I need it. But I don't want to go out. I slowly opened the door. He was standing there with a smile. Two Panta bottles and a key. MY key. 

"F-fine. Come in. I don't want anyone to know." I said. 
He entered and sat on the bed. 
"This place is smaller than mine." he said. 
I silently nodded and continued to do more doodles. While of course sipping Grape Panta. Nothing is better than that. I continued to draw even though he tapped my shoulder. I continued to draw and eat when he brought me food. 

By the time I noticed there was murders occurring. I didn't attend trials or what ever it's called.  I didn't even go out. So I didn't know what the outside was like. How Monokuma made people kill. I continued to draw. But then I eventually noticed what I was drawing. It was small at first. It was like a background character but now it was big and huge. It was kinda like a portrait. 

I smiled. In the first time in my life. I felt happy. I lifted up my paper and hugged it. Well it was a picture of him hugging a bottle of grape Panta. Why not hug it back. 
"I like that. I like what you drew." a voice said beside me. 

I nearly fell off my seat. 
"When were you here?" I asked. 
"I was here since when you let me in. I do have the key after all." he answered. 
"You look kinda creepy. What kinda a leader are you?" 
"It's a secret."

I frowned. 

"Fine! I will not even tell you my secret!" I say back. 

He then pouted. He pouted! He looked so cute. 

"Fine! I'm the leader of the Monokuma's! Do you hate me now?" he asked. 

"No! And my secret is that I..." I stopped. 

"Wha-... mhmmm.." 
I kissed him. Well should I say I got bitten. He was stiff for a moment until he understood and kissed me back. 

"I don't know how to deal with this..." I mutter. 

He then picked my chin and lifted it till I can see him exactly in the eyes. 

"Males are suppose to do that you know~!" he cooed. 

My face was definitely red. Bright pink red. 
"I-I...uhhh...i..." I stammer. 

I can't speak. I can't speak...

"I love you." Ouma said with adorable eyes. 
"I love you too." I say shyly. 
"Should we go to the outside world?"

I just nodded. He knew how to let us out.
We safely escaped that prison to lead the Monokuma's to the future. 

But the thing I didn't know is that the person who was trapping me in that prison was him in the first place. That he was the one imprisoning you. That he... was.... the mastermind him self....

*FLASHBACK*Kiibo confessed to me! OMG!"I know I am a robot but please! Be my girlfriend!" Kiibo repeated. "YES!!" I exitingly replied. The thing I didn't know was that someone was staring at me with lustful eyes. *END*

Kiibo's POV

I walked up to my room to notice a door. It said (y/n) (l/n). My robotic head instantly reconise that name and opened the door. But only to see it empty with Ouma's scarf fabric and (y/n)'s sun glass case. Where did you go?
