...Perhaps Naoto should be used to strange things and strange people. Personally, she feels like this boy is having a rather intense under reaction to the situation. However, the Shadows haven't already destroyed him... would that mean he has the potential? (Admittedly, that is hardly Naoto's expertise in understanding. She may have to call Mitsuru-san as soon as this is over.)

"Being on guard," is her answer; if he hasn't seen Shadows yet, there's no sense in trying to explain something that abstract, "Are you alright?"
