For three years, the Mazaki's have lived in New York City until Mr. Mazaki found a new job located in Domino, Japan. The Mazaki Sisters didn't want to leave their home in New York City but they had to leave because their parents were going.

It took one year for the family to move to Domino since they had to sell a few things before the Mazaki Family can start their new lives. When they got to Domino, Anzu, and Arisu didn't like their new home because they didn't have friends at the time, or other family that lived in Domino. Their father, and mother assure them that if they go to school, then they will meet other children, and make friends with them. On the first day of school, the girls went to school and like their parents told them, they made a few friends. Anzu was quite popular, but Arisu wasn't since she was practically invisible by everyone until she met a certain person that felt invisible just like her: Yuugi Mutou.

Arisu felt curious about Yuugi's hair since she's never seen hair like his, so she walked over to him watching him play his game; he noticed her, and asked if she wanted to play. Both children played the Game boy together, and soon became friends. A month later, Yuugi became friends with Anzu almost the same way he made friends with Arisu except he gave her a game to play, which she broke. Ever since, Yuugi and Anzu became friends, Arisu felt jealousy towards Yuugi since he took all his time with Anzu since Anzu stopped spending so much time with her. So, Arisu told herself that she wasn't Yuugi's friend anymore because she claimed that she hated him.

2 years later, Mr. Mazaki got a better job offer back in New York City, but his wife didn't want to go so they got into problems. After discussing the problem, Mr. Mazaki got his things, and took Arisu with him back to New York City. The twins were separated after that.

When Arisu was 8 years old, she was walking home from school; she noticed a dojo, which caused her stop wondering what martial art, was taught in the dojo. She sneaked into the dojo, and saw men of all ages, and races doing kendo in that dojo, but she saw a girl around the age of 13 to 14 doing kendo gracefully that she started to admire the girl and decided that she wanted to do kendo, too. So, Arisu randomly got a kendo stick, and tried to use it, but found the stick to be too heavy for her that she dropped it getting everyone's attention even the girls'. The master of the dojo wanted to see what was going on; that he saw Arisu and noticed something about her reminded him of his own daughter that he decided to help her train in the art of sword fighting which she agreed. Arisu's partner was the girl that she admired because she wanted to be strong just like her partner since she always thought that without Anzu she was weak, and felt alone, but ever since she trained kendo she felt stronger, and a bit more confident.

When Arisu was 14 years old, she was training kendo with the same girl that she met when she was little. The girl had to leave New York City, but she promised that she would still try to do kendo as long as Arisu didn't give up on her dream to become 'Mistress of Kendo'. Arisu agreed that she said her good bye to her only friend. In the same year, her father grew sick that cause him to stay in the hospital. In only 2 years, Arisu found out her father had cancer in the stomach, which she stayed by his side everyday for an hour or more. She still trained the art of sword fighting because it was the only thing that gave her strength. 2 years later, Mr. Mazaki died from the cancer that Arisu felt sadden by the whole thing, which got her more determine to do kendo, but her training wasn't helping her at all. Her sensei found out about the loss of her father, he showed her the game of duel monsters, which he taught her how to play.
