Basic'ly... Earlier on in the day, a number of new students arrived at the dorm and a degree of hilarity was had as they settled in. That evening the group headed out to a local nightclub for some TOTALLY NON-ALCOHOLIC hijinks. Halfway though, the lights cut and and surprise surprise, it's Dark Hour; why no-one in SEES thought to keep an eye on the time is beyond me.
They all headed back to the dorm to kit up and drop the kids off, but became seperated. Yoromatsu and Youhei are on the train now, in a losing fight with a horde of Shadows with Takahiro supporting over the radio. Everyone else is still at the dorm, though I think they'll be getting a move on soon.
So you have two groups that could find you, your choice which :3
