Rei is kind, sweet, and quickly becomes popular, contradicting Sakura's accusations. Soon enough, she learns his true nature: a Code Breaker, or "one who does not exist." To Sakura's shock, Rei—armed with mysterious powers—seeks to exact justice according to the principle of "an eye for an eye." Determined to bring Rei to the right path, Sakura keeps close to him in the hopes of redeeming him from his ways before others are hurt. [Written by MAL Rewrite]
