Jack shrugged, then said casually, "If that girl is going out, I think I should go with Shiro. The fact of the matter is we'll likely get in a fight and one of us will return with food while the other does not return at all. Those other two... I think it'd be best if they remained with the train. The reason behind this is because, while I have no idea what they can do, they must be able to do something to have survived the first day. Besides that, we need people to defend our only mode of transportation. So Shiro, if you object in any way, now would be the time to tell everybody."
