Apolaki
Of the national team members in Apolaki's group, only he did not need to audition because he already got the part when his name got popular in the scene. It is actually the highest ranked player in their country that told the recruiters to prioritize him if they wanted a medal in the upcoming Pandelympics.
Needless to say, Apolaki gladly joined the Pandelympics with the consent of his clan. They usually do not trouble themselves with the outside world but gaining an achievement for the country takes precedent which is why their clan will give the country athletes to win medals in the Olympics and such.
This is no different as it is a prestigious event that is paid attention by the world. Since Apolaki is actually one of the few that play Pandemonium in their clan, he is given the opportunity to show his prowess. He is the perfect example of applying the rules of the real world to virtual reality because he has formal training.
