To the people complaining about two groups translating: both mangadex and tachiyomi have block/filter features so you don't have to see the double updates. Though I think it's perfectly fine to have these two groups.
I read both, especially since this manga is a monthly release, and can always use a refresher with all that time in between. Sometimes this group has more accurate/better translations. Sometimes the other group has the better/accurate translations. Sometimes, they both don't get it quite right.
And more often than not, scanlation groups abandon projects out of nowhere, and if 2 groups are doing it, then there's always a back up if one of them ups and disappears, instead of having yet another manga left abandoned and untranslated before it finishes like so many on the sites.
