She later fails in her goal, as Touma refuses her rescue in order to save the world. This finally goes to head during the climactic ending of Toaru Majutsu no Index with World War III, where she goes out of her way to go to the battlefields of Russia to find Touma and bring him back. Mikoto's character involvement in the plot was not of the greater story unfolding but with her continual association with Kamijou Touma. Moreover, in spite of Touma's insistence in not getting her involved, Mikoto only persists. It is not until her discovery of Touma's memory loss that she tries to actively become involved with him. Her role as such remained as is for her earlier appearances, with her getting involved little with Touma's adventures and even then completely unaware of what's truly behind the surface. An example of this is her overhearing of Touma promising to Etzali that he will protect her and the world around her. Like with the Toaru Kagaku no Railgun sidestory the Sisters Arc marks a turning point for her character, which is heavily explored in later appearances, far and few they may be, as a character that has a crush on Kamijou Touma but cannot properly express it. In her reappearance after Touma's memory loss, she acts as the main heroine along with her Sisters. Index PSP Game Misaka Mikoto's role initially was that of a minor character known to Kamijou Touma before his memory loss.
