Princess of VERS.15 years after Heaven's Fall, the Princess of Vers, Asseylum Vers Allusia, travels to Earth on a diplomatic mission despite discouragement from her close companion, Slaine Troyard. Back on Earth, Inaho Kaizuki lives in the city of Shinawara, Japan (a fictitious version of the real-world city of Awara) with his elder sister Yuki. Yuki is a Warrant Officer and a Kataphrakt pilot in service to the United Forces of Earth (UFE), while Inaho attends Shinawara High School and trains to be a Kataphrakt pilot. When Inaho and his friends go to see Asseylum's motorcade, terrorists attack the motorcade of the Martian delegation with a guided missile. Although it initially appears that the limousine carrying Asseylum successfully avoids the attack, the terrorists successfully hit the limousine with a second volley, and it is believed that the princess is killed. In retaliation, the Vers Orbital Knights launch an all-out assault on Earth via the descent of their Landing Castles from Earth orbit and launching missiles, which destroys undersea cables, geostationary communication satellites and major cities. A pair of young children mistake the streaks of light in the sky caused by the descent of Landing Castles for shooting stars and wish for world peace.
