Takuya is a happy, energetic 5th grader with a strong sense of justice. He is very athletic and a member of the soccer club. He can be very hotblooded and many times jumps before thinking. He gets into the Digital World by following a mysterious email left on his cell phone.

Koji is a cool 5th grader and more of a loner. Due to his father, he has had to change schools often and because of this, he is not very good at making friends. Koji somehow got to the Digital World thru a different path than the others.

J.P. is a very reasonable 6th grader and considered the mood maker for the group. He is not very good at studying, but is knowledgeable about things such as trains, stamps, and cards. Also, he enjoys telling fortunes.

Zoe is a pretty 5th grader who has just returned from living in Italy for two years. She is happy that she is 3 months older than Takuya. She has a tendency of saying whatever she feels which accounts for her strong personality. Fact is, she is really looking for true friends.

Tommy is a pretty dependent 3rd grader. Obviously, he is the youngest of the group and quite a crybaby. His older brother never played with him so he would occupy his time playing on the computer. He is very timid, but open to expressing his feelings. He came to the Digital World, because he had been bullied.
