Who am I, why am I here, and what kind of life have I lived? There was not a single question I could answer for myself. Every memory from before I opened my eyes has vanished.

The very first thing to fill my empty canvas was the fact that I am a 'test subject' here. I was originally meant to be discarded as a failure, but Sion, who valued my unique constitution, supposedly hid me away for his research.

I don't think this is wrong. I was destined to die anyway. If the price of my life is a few needles in my body...

I can endure it. Because if I lose even this modicum of usefulness, I really will be discarded.
