It's not a small event for homos (which I doubt could sell a 1500 seats event) but it has at most 4000 people in a tiny corner of the area watching a glorified live streaming with the NIjis in 2D, sit down and talking to each other.

The only reason this event even happened in the first place

was to make possible for people to say Nijisanji had an even at the Budokan when an even of this type could easily have happened in a slightly larger IMAX theater

the other was the "collab with the NBA". They live almost exclusively of appearances and, as mentioned, the great majority of their male vtubers range between Uyu and Roberu with the notable exception of the "anointed" protagonists
