Well judging by the ending of season 2 it is quite obvious that the writers planned to make another season.There is nothing official on whether или not there is going to be a season 3 but on an episode of Angel's Друзья on Youtube someone asked if there is going to be a season 3 to which Mondo World(the company that made Angel's Friends)replied by saying"Its still not finished"which means that season 3 will come out once they finish it.
i am not sure but the might be a possibility for a 3rd season because reina got out of limbo and raf and sulfus has to go through the path of the metaphorthises.
