Are Revy and Rock together?
I don't think they are ever officially romantically involved in the anime but we see their relationship progress towards it throughout the anime. There are clear signs of Revy having feelings for Rock(cared enough to point a gun at Balalaika) but Revy's tragic past has given her intimacy issues.
Was Black Lagoon canceled?
Prior to the artist's passing, it was announced that the manga series was being cancelled so that Kayaharuka could seek treatment for pancreatic cancer. Black Lagoon was adapted into a two season anime series in 2006 by Death Note and One-Punch Man studio Madhouse.Jul 26, 2021
