do we know at which date the daihaseisai arc was over??
because im pretty sure that this would be the only timespan in which we didnt see mikoto
the timespan between 30.08 and the end of daihaseisai....
the other ones would be while vol.14- vol.16 but she was her usual self and seemed to have only touma in her head)
vol.17-WW3 well, if im wrong than this should be the next possible arc....
their isnt much time between the events, so it is hard to make a proper guess about the next arc-time
at least if we take the railgun manga as canon, is it canon??
