I used to be weak and lonely.For the research institute, I was nothing more than a poorly-made lab rat. Nobody loved me.However, the institute didn't treat me any differently."Why am I being treated like crap by these humans even though I am so much better than them?" Thinking so, I started to get irritated with humans.I bided my time and patiently waited for the day when all the staff would be present at the institute so that I could carry out my plan to crush them all.At that time I thought humans were stupid, but perhaps it was me who was stupid. It was a rather embarrassing... dark past of mine.Thanks to a certain person, I awakened an amazing life force, and I was no longer weak.Now that I think about it, it was all useless. If only I had just escaped without getting hung up on killing everyone, I would have been free that much sooner.
