I am just a robot that was made, By a very lonely scientist. My creation was a miracle, Of science. Yet inside me there's a missing part, Something that you can't simply create, It is software humans called a 'heart'. In a program. One hundred years, slowly passing by, I was alone with no one on my side. This robot has just one wish to share, One small hope. Who was the man that created me? And why did he work until his dying day? Just to invent with his technology, (Kokoro.) Now this program installing in me, Leaves my heart accelerating. Why do I see all these tears, falling from my eyes? I am shaking and I'm trembling, I hear my voice, it's wavering. Is this what he made just for me, my very own kokoro? (Mystery kokoro, kokoro mystery) And now I know truly how happiness feels. (Mystery kokoro kokoro mystery) And how this sadness in me seems so surreal (Mystery kokoro, kokoro mystery) And now I understand what it means to me! Ah ah aaaah!~ I am finally coming to see, The reason I was built in this world. It must have been sad for him lonely and alone. I'll remember him in memory, I will always keep him with me, I only wish that he'd lived to see kokoro set me free. I can sing now the purest melodies! I dedicate my song for you! (Thank you, my friend!) x2 Even though you are gone you have shown me the light. (Thank you, my friend!) x2 Thank you for everything you've done in my life. (Thank you, my friend!) x2 Thank you for the many days that we spent together. (Thank you, my friend!) x2 I will sing of you forever!
