Toaru Majutsu no Index Episode 18

Synopsis
Mikoto overhearing their conversation, is visibly reddenned by Touma's answer and tries to shake it off. She says to herself that he is the kind of person who would say such irresponsible things, and denies to herself that she is something special to him. She rests her on a metal beam and looks at the sky, stating to herself that even though she is misunderstanding him, his words are very misleading.
