>>14826756It was shown when Enna accidentally flashed her discord, I think.
Also I'm pretty sure they've mentioned talking to their managers on there (as well as Slack)
>>14825968 is also a retard, their names are all DIFFERENT colors on the private discord, while I assume they're colored by wave or something on the official one, with LazuSydia folded into one group. They probably didn't add the boys to the private one until recently, so no one accidentally leaked it.
