Hello there.
I'm a robot.
My name is Rin
Here is my story


"You can open your eyes now" I heard a man's voice, loud and clear

I opened my eyes. The light I saw hurt it badly for I never opened my eyes before. I saw a man-no, it's more of a boy, standing in front of me. He was smiling. The boy had quite a long hair in which he tied it up into a tail that is hardly visible. His blue eyes shines and hopes. My system says he is the one who invented me.

"Do you know who I am?" he asks

"Yes," I answered "you are my inventor."

His smile widened. He stretched his hand over to me and waited. I looked down at his hand and at his smile. I had no clue on what to do.

The boy still waited for me to do something. After a few while, his smile turned into a look of confusion. It is probably because I did not do something I was supposed to do.

"Oh well," he shrugged "I'm Len by the way. Are the systems working properly?"

"Yes." I answered

"Well if it is, then you should be Rin" He smiled again.

For some reason, I could not push my mouth into a smile like Len could. Something inside of me prevent that to happen. I could also feel nothing, unlike Len. I could not hope, or wonder, or be amazed. It is clear that Len and I are very different.

"Rin, you're finally born." He smiled, a different smile this time, he is in awe "It's a miracle."

Miracle, that's how I was born.

Hours later, we spend time together, playing and telling stories. I could tell that Len was still a boy. According to the information I got, children have parents. The parents took care of the children, teach them, protect them, love them. Yet, Len did not seem to mention anything about his parents. Is the information in me wrong? Did something happen to him? Is there another probability?

"You may be wondering why I didn't talk about my parents." Len suddenly said. It was as if he could read my mind.

"My parents left me." his face, his expression changed. His eyes were not focused any longer. It was as if he was drifting to the past "I was alone, until you came."

He smiled once more. I could not understand how Len could smile in such a sad time. I could not understand anything he did. He had so many features, I had nothing. He can feel, I could not. I guess it is normal. After all, I am just a robot he made to fill in his loneliness.

"Hey Rin," Len took a piece of paper from his desk and give it to me "let's sing!"

I looked at the paper in my hand. I know how to read notes. I also know how to read words. I know how to sing. I know how to do everything we are going to do.

Len sang beautifully. I, on the other hand, sang notes. Len says that my singing was wonderful, as I was, but I know I did not. I know why to. I did not sing by heart.

"Len," I interrupted our singing. Len stopped immediately

"I cannot do this." I say

"Why not?" he asks

"You can sing with you feelings. You can be happy, sad, in awe, while I cannot" I explained with monotone voice

He frowned "I understand."

Len took the paper in my hand and put it back on his desk. He sat down with his back on me and started to think.

"Why are we not doing anything?" I ask

"Rin, I think I know what you need." He turns to me "You need a heart. And I'm going to make one… a software, called Kokoro. Yeah, Kokoro"


That is the start of everything, the day Len planned Kokoro. That software is now inside me.

Kokoro is now inside me.
