Nameless after school club

Saya, Hagi, Riku and Kai were all at the house that belonged to their dad but is now there's since he is past on. The night was cold and dreary as they all sat around the table nibbling on some food they picked up at the supermarket. Saya's cell phone rang it was David telling her she and here family need to leave right a way to go to the states and take care of some business. So they went go there tickets from David and headed off ahead of David and the others. As that got on the plane they though where are we going too we never read what the tickets said.
