20

Rati challenges Misaki to a fight where she reveals her past to her. When Rati was very young, she and her father traveled around the world selling doughnuts. In order to break Rati out of her shyness, her father introduced her to Vanguard. The more Rati became engrossed in her fights, she developed a strong attachment to planet Cray and its inhabitants. As a result of constant traveling, Rati realized that she never built any strong relations with any of her opponents and started to believe that bonds such as friendship never last. After the Link Joker affair, Rati became a Quatre Knight because Aichi saved her, and thus is devoted to him. During the fight, Misaki tries to convey her desire to become friends with her, but is ultimately rejected and beaten by Rati. In the end, Misaki loses her memories of Aichi and is sent back to Earth where she becomes saddened over forgetting something important. (Source: Wikipedia)
