For other cons, Phase did have a decent presence at Holiday Matsuri in Orlando in December last year. They had a booth where they sold merch, had meet and greets with some of the girls, and did an exclusive show there (it was just Remi, Airi, and Uruka playing Jeopardy, but there was some crowd interaction). The issue with that con is it's more general anime/nerd focused, and I think Fishman knows they get more recognition and merch sales at a con that's only about vtubers like Offkai. It's up to him if he thinks the bullshit dealt with is worth spending his money to get the company's name out more.
