Despite Othinus trying to break his will him, Touma still decided that it is alright if everyone abandon him and that he will just rebuild his connections with them. Othinus then asked him who he is, then Touma realizes that he no longer knew who he was. While Touma is contemplating about his identity, Othinus asked his name, what kind of person he is originally, the kind of people he is surrounded with, as well as the person he wanted to protect. She told him that as thanks for letting her kill some time, she will return him to his former position as long as he tells her his proper name. She showed him his own class photo and told him that if he chose correctly who he is in that photo then she will return his world, life and existence. Despite the fact that Othinus is trying to break his sense of identity, he insisted that he is Kamijou Touma. Othinus utterly displeased asked how did he catch on to which Touma replied that she gave him a hint.
