Cia: Moral Hero How: Cia wants to attend the University really bad and pass the Testing, but won't do things that are wrong and hurt others. She often helped out others by giving them information when she didn't have to. She helped Brick out this way.
Tomas: Reliable Friend How: Tomas is Cia closest friend from home at the Testing and the only person she really trusts. Tomas proves he is reliable when he helped save Cia from falling into the water off the bridge. They make a pack to meet up and help each other find their way back from Chicago to Tosu City.
Roman: Evil Trickster How: He answers all the questions for the group testing in part three. Roman did this on purpose so everyone after him in his group would fail or get a bad punishment. He didn't care at all that bad was going to happen to them.
Ryme: Friendly Intimidator How: She appears to be really nice and friendly, but she tried to make Cia feel less smart and that she was smarter than Cia. She offered her corn cakes to be nice but they may have been poisonous.
Brick: Loyal Returner How: Brick was not very social with Cia to begin with. He worked with Cia in the third part of the Testing. Cia helped him by telling him that Roman was tricking them and she was right. This saved Brick. So later Brick returns the favor and helps Cia out.
Zeen: Unchosen Inventor How: Zeen was really smart and invents things for the Five Lakes Colony to help them. Cia takes his transit communicator invention as one of her items to bring. He is smart, but does not get selected to the try for the Testing. This makes him sad and jealous when Cia gets picked.
