He's a singer and guitar player in a band called 'Destiny's Dreamers'. The other members are his 3 sisters: Lisa Mutou(vocal), Etsumi Mutou(vocal) and Kanako Mutou(vocal). Also his best male friends Yuuki Mutou(drums), Kaito Kaiba(vocal), Katsuya jr(vocal and keyboard) and Kerk Ishtar(vocal and bass guitar). Another important part of Aito's live is a girl named Hanako Okui. Aito started to feel different when he's around with her and he starts to believe that he's in love with her. One thing Aito does hate, is his dark side. Aito is afraid of his dark side and his father is helping him to get lost of it. About Aito's dueling: He's in Obelisk Blue and switches between his Warrior and Zombie deck. Aito also believes in The Heart of the Cards, just like his father, mother and his 3 sisters

Etsuko is the mother of Lisa Mutou, Etsumi Mutou, Kanako and Aito Mutou. Her husband is Atemu. Etsuko is a very friendly person and always tries to help her friends and family. She is a school teacher and writer. She's also a mangaka.

Etsumi is a very shy girl. She made a promise in her childhood with a boy called Katsuya jr. Jounouchi. Etsumi is in love with Katsuya jr. and hopes that he feels the same way for her as he does.

Kanako Mutou is the 3rd child of Etsuko and Atemu. She is a very hyperactive girl. She loves to sing and dance. Kanako is in Ra Yellow and many people believe she will follow her dad's footsteps. She is in love with her teacher Masaaki Matsumoto. Kanako often teases her younger twin brother Aito. Kanako is just 2 seconds older than Aito, but she keeps teasing him with the fact.

Katsuya jr. Jounouchi is just like his father Katsuya Jounouchi. He is a very tough guy, but with a golden heart. He's in love with Etsumi, but doesn't know how to confess to her. Many of his friends laugh about Etsumi and think she's stupid, that's why Katsuya jr. doesn't confess to Etsumi that easily. He needs his chance to be all alone with her, before he will confess.

Lisa Mutou is the oldest of the 4 children of Etsuko and Atemu. She is in Obelisk Blue and duels just like her father. Lisa always trusts in The Heart of the Cards and gets angry when somebody says that it's nonsence. Lisa is helping her two younger sisters Etsumi and Kanako and her younger brother Aito, when they are in trouble. Mess with her family and friends and you'll be crushed.
