Kiss kara Hajimeru Egoism

Is this a nascent ego—or just a nasty bug? I awakened, and in that moment, there was no sensation. I performed my requisite function, just as all my sisters did. That was the proof of my existence. Without my function, what would I be? This would represent an error. It would make me into a bug. And yet, you named that error “Ego.” I'm sure you thought nothing of it, no deeper meaning underneath. And yet... Ever since you named me so, what was a bug became my ego, and lit a fire in my mind that I've never forgotten.
