Cooperation or competition, that's a question worth considering.
If according to the curse of the Puppet Masters and the Secret Garden Elves, only one hunting team out of all those entering the hunting ground can survive, then from this perspective, each team is an opponent—opponents to the death.
However, if guided by the principle of 'rightness', all hunting teams should unite and resist the tyranny of the Puppet Masters, striving for everyone to escape from the hunting ground in unity. From this principle, each hunting team is a potential ally.
Whether they are opponents or allies depends on the choice of each hunting team.
