Characters featured from left to right: Hebereke, Spelunker, Kanna, Ripple, Peter Pepper, Tam, Rit, Gonbe.
Judging by Hebereke's thought bubble, the queue to buy tickets to watch Smash Bros duels would be a long queue because in order for video game characters to buy tickets, the ticket seller would have to identify whether the customer is wearing an appropriate attire before the customer can buy a ticket. This could explain why Mai Shiranui was missing from Super Smash Bros Ultimate's King of Fighters Stadium's cameo characters list, given that her exposed cleavage would displease CERO, the ESRB, and PEGI.
You can see that Rit is buying two tickets, one for her and one for Tam, as they both come from Jaleco's Rod Land.
Being seventh in line in the queue isn't so bad, but when one is being analyzed for anything inappropriate or unacceptable, which none of the characters queuing for tickets have, expect the ticket seller to do a thorough search on the customer to find anything inappropriate or unacceptable, and it will cause delays in what would be an otherwise normal queue for tickets. This method of searching for anything inappropriate or unacceptable ended up barring Mai Shiranui from buying a ticket to watch any Smash Bros duels.
On a side note, congratulations to Byleth on qualifying for Super Smash Bros Ultimate's final Fighters Pass slot, even if reception was as bland as that towards Piranha Plant.
