>>74072818Ariane arena has a maximum capacity of 15k which is only possible in the centre stage configuration with an arena seating of 3.6k.
Since Pekora's was a vtuber concert and looking at
>>74071943, it seems she chose the one with 12k max capacity and arena seating of 3.6k.
Deducting from total no of spectators, we get stand seatings at a max of 8.4k. Since 1/3rd of them have to be closed off as you say, it would leave stand seatings at a max of 5.6k.
Combining with arena seating, the max capacity comes out be 9.2k.
