when you woke up you were laying on an operating table, you didn’t know who you were and what your purpose was

when you stood up there was a blue haired man with red eyes, he then greeted you with a smile and say

"Oh my... i didn’t really think this experiment would be successfull but here you are... by the way... your name is epsilon and you're one of us"

you didn’t know what he meant when he said "us" but when you looked into a nearby mirror... you look exactly like him... you are him
