I'm delving into the history of shadowrun in regards to the matrix. Deckers are easier enough to find, but in what editions are Otaku prevalent and which books for 1-4e would I need to look for a 'complete' history of the character type. I know they exist in 2e, but the 3e core seems to be lacking in the Otaku info.
Just looking for the books in which Otaku are the Main ish focus, or core books so I can read the Mechanical and fluff evolution of them.
Thank you for the info in advance. <3
