Oh, I forgot to write on the creds page. This is not a side story. From vol14 and on, the last chapter highlights what happened to Id prior to coming to the alternate universe and how he came about to this other place.
Please read the creds page’s long wall of text. kthxbai. 😛
|Id Vol 14, ch 4 (aka 90)|
