Kazuki goes to an empty store to buy medicine for the injured pilot, but the UN forces pick up the pilot and Hartzenen before he returns. Finding the pilot (whose name is Yayoi) missing, Kazuki searches through empty streets. Soon people begin to return to the city and Kazuki goes to his house, but none of his things are there and his parents don't know him. Soldiers, led by Mitsuki, take Kazuki into custody and bring him to Headquarters. Ken Sanada of this world greets him, then explains that he (Kazuki) does not exist in this world and Mitsuki is from his own world, but she arrived a month earlier. Ken Sanada is the UN leader of the Global Defense Force and the world is at war with the Rara army led by a fellow scientist named Hiroshi Rara. Mitsuki is a pilot of one of the core robots and figures if she fights to help end the war faster, Ken Sanada will have time to make the portal back to their original world. (Source: Wikipedia)
