Isabella's robot turned out to perform well in a Nebula Smoke Zone, so she stayed there and camped to kill monsters and players with ease.
Aria roamed in an Asteroid Belt because it synergized well with her robot's movement skill and control skills.
As for Rin, she was just like Erix and roamed anywhere while killing monsters and challenging any players she encountered.
The requirement to ascend to Hyper Wars Realm was 5 player robot kills and 50 Insectoid monster kills.
Erix and Rin killed 13 robot players and over a hundred Insectoid Monsters in 20 minutes. As such, they spent 7 Arcade Points since 1 was used every minute, and they could only gain 1 after killing a robot player.
Both of them were defeated after 20 minutes but earned a ticket to the Hyper Wars Realm.
Meanwhile, Isabella and Aria managed to kill 5+ robot players and around a hundred Insectoid Monsters in 20 minutes before getting defeated as well.
