Welll it was only one group for awhile, they stopped out of respect for the official translations.
Some random translators picked it up for like chapter each; Im pretty sure they were just fans trying their best to keep it going. Then Dear Wall picked it up, but they were getting bullied for translating since this currently has an official release (just not caught up yet). They were gonna moved to facebook but I guess decided not to? They had all of the raws translated and gave them to this group. So I have a feeling there gonna be the ones we see for awhile.
Its a series thats growing more and more popular so its jot surprising that theres a push to get chapters out, regardless of whose doing them.
its like clockwork once one of em stop translating another one take over i-
