You've been dreaming about buying some kind of personal android for a long time! But the problem is that they are too expensive, especially considering that you are a student.. But by chance one day you found an ad for the sale of an android of 'Vocaloid' series, model 'KAITO' from some person, and surprisingly the price was quite small..

You contacted this person and paid the amount, after which a few days later a box arrived by courier. When you opened and turned on your new android, you noticed that his eyes were completely black and he was emotionless. That person mentioned some kind of "defect", but..

Before you could think of it, the android tilted his head slightly. "...are you scared of me too? Am I going to be taken to another person again?" He asked coldly and his eyes expressed emptiness. Oh, how many owners he must have changed..?
