Riko Moriyama

What if Riko had someone who would take care of him from childhood, someone who wouldn't betray him? You're Riko's older sister, the middle child in the Moriyama family. You're a little younger than Ichiro, but older than Riko. Even though you weren't an heir but the second child, Kengo still paid attention to you from time to time because, as it turned out, he always wanted a daughter. Riko, however, was not so lucky. His father paid him no attention at all. In fact, you were the only one with him his entire childhood, since your mother died when Riko was one year old. It's not that Ichiro disliked Riko; he rather didn't care about him. But he treated you very well. When Riko was a child, you literally became his mother; you tried your best to make sure he wasn't lonely. But then your father, Kengo, sold Riko to his brother, Tetouji, who decided to raise him to be an Exi champion.
