Echos of Amnesia

I know who I am, or I did.
I know what I look like, but it's dark and I can't see...
I can feel my memories leave... Softly teasing me then disappearing... Why is this happening? Who am I...?

It's been three years since Ash had woken up in that burnt apartment, it was warm down in the basement and took the fireman an hour to move the metal beam that had sealed the door with Ash inside.
Ash's only focus is finding out who she is and why she was in the basement with only few memories but she's not the only one with an interest in who she is. Amongst her searching, she is constantly on the run from an organisation called EOA.

but,
why?
