Naoto wakes up with a gasp, the taste of fog still heavy in her mouth and the ever-present echo of a heart monitor flat-lining ringing in her ears. A glance around her told her that the plan at at least succeeded in sending her back - she was in her bedroom in Tokyo, and a check of her phone tells her it is April 10, 2011.

The phone vibrates a second later, and a string of messages appear as she flips up the screen - Yuu had been appointed as the one who would contact them all to see if they had made it safely, but of course everyone else would check in too - and Naoto smiles for the first time in a month.

The smile morphs into a determined line as she texts back, knowing they would have to act fast to save Yamano Mayumi and Konoshi Saki, and she vows that this time, Yuu's December would be happy and full of life.
