I'm an alien who implanted a piece of metal in Lain's body.
The other day I visited the earth, abducted Lain as a sample of the earthlings. I tampered with his body to gather data of the earthlings.
But I made a terrible mistake.
Lain's fat body is a nonstandardized article as an earthling.
He is unemployed, and on top of that he has no friends.
All day long he is sitting in front of the personal computer, clattering clattering, clattering the keyboard.
I am fed up with this job.
Boss from mother planet yelled at me for this failure.
He said, "Select your specimen more carefully!"
This is the first penalty I get since I have been assigned to The Earth Observation Party.
The human mutilation is not easy task.
Next year I am demoted to the charge of the cattle mutilation.
I am just about to go to The Area 51.
As for Lain, I leave him entirely up to you. Do as you like.
