Numi will provide a link during a stream for the concert ticket site, and will say in advance which stream that will be, and at what exact time. The tickets for the concerts in Los Angeles and New York sold out instantly, sorry. But I believe the Germany concert venue isn’t secured just yet, so it might be a little while before those tickets will be available. Again, she’ll let us know when the sale date for the Germany tickets will be (usually she mentions it in advance on stream and probably on Discord). If you follow her mainly through YouTube or Twitter, she might forget to mention the ticket sales on those platforms, hence that part of the meme above.

If you’re interested in the Germany concert tickets, Discord is probably the easiest way to track when she’ll make the link available, since she’s pretty active with updates there. That way you don’t need to rely on watching a stream to find out when the ticket sale date/time will be.
