Lupin the 3rd
I keep telling the Mangago staff that these chapters are not from the original manga, & where they can find them, but they refuse to take the Lupin Sansei Y chapters down, even though they're already uploaded elsewhere on this site. So all I can tell you guys is to go read it on MangaDex instead.
