So I was wondering who this guy is/was http://manga-joy.com/wp-content/manga/14808/18/018.jpg

I wanted to search on the wiki to find out, but didn´t really know what to search, for since I thought searching for "Creepy shadow guy" didn´t seem like it would give me a lot of answers.

If you know who and or what this person/thing is please if you would be so kind, leave a reply. If you have any other spoilers about this man/thing/object then feel free to share those two.
