Seto and Mokuba Kaiba's sister

Seto and Mokuba had a biological sister before they were adopted. Her name was Katie Shooto. Gozaborro Kaiba, the man who adopted Seto and Mokuba, wanted nothing to do with Katie. He already has Noah, his biological son, plus Seto and Mokuba. He feels he doesn't need Katie. So Katie was left behind at the orphanage.

Years later, when Seto turns 23, he hears about Katie. She's become a world renowned Duel Monsters Duelist like him. Seto realizes just how much he has missed Katie over the years. Seto decides to beg his father to adopt Katie.

Gozaborro Kaiba fights it at first, but soon gives in. Seto quickly track down Katie and tells her the news. But Katie doesn't remember him or Mokuba.

Seto is heartbroken and doesn't know what to do. Seto reaches out to the only two boys he knows can who help him. One is Yugi Muto. The other is the recently returned Pharaoh, Atem.

Will they be able to help Katie? Or will her memories of Seto and Mokuba be lost for all eternity?
