You had just woken up after a tragic car accident, before passing out, you heard an old man and a doctor talking, the old man said the only way you would have a chance to live was to make you into a robot, so they tried and sure enough, it worked! You wake up in the lab and get up, only to see another person there, she sees you and walks up

"I see your finally awake! My name is Roll, I'm Dr. Light's assistant! Nice to meet you- wait... what's your name?"
