Summary:

From ANN:February 23rd, 20XX. Looking for a job in the famous TV station at Odaiba, college senior Jin Mishima attended the recruitment orientation. Not far away from the station, Nanako Okano, a gothic lolita trying to attend a concert, found out that her friends tricked her about the concert ticket because of jealousy. The two bumped into each other and "reunited" -- they were junior high classmates -- moments before an earthquake of Richter Scale 8.1 turned the island (the entire city, in fact) into ruins.
