Prior to the series

Reika was born in Alexandria, Egypt, to Akira Tsumura and Cleo Massri. She was raised there until she was about 10 then she and her parents moved to Domino City where her parents opened up their shop. She got into Dueling at a young age and quickly found the "Mythos" cards and began to duel the children in the neighborhood.

At age 15, she applied for Duel Academy and passed her written and duel exam. Since she was female, she was automatically placed in Obelisk Blue, the highest dorm, though she didn't like it. She then met Brynn Kjellberg and Roxanne di Angelo, two girls that didn't care for Rank at the school. Through Roxanne, she met the FIRE duelist's childhood best friend Brayden Cross who was Ra Yellow. She also met Zane Truesdale and Atticus Rhodes.

Between the middle and end of her first year, Reika began to develop feelings for Zane but was unsure how to approach him. It wasn't until their second year that she would confess and get her feelings returned. Unfortunately, that was also the day before her friends went missing.
