The sun began to emit increasing levels of radiation in the first year of the new era (2012). A few years later, children with unusual powers, known as 'Allergies,' began to be born. Amuri Kakyoin is a 13-year-old girl who was born with a rare 'Allergy' known as 'Repulsion.' This talent protects her from damage while also preventing her from contacting most of her surroundings. In the year 019 (2030), mysterious attackers from the trash planet Galapagos assault and destroy the space station Pink Coral during a voyage there. Because of her 'Allergy,' Amuri survives being sent into space, but is captured by the assailants. When the Galapagos robots try to destroy her, a girl named Ling "Suzu" Yunque appears.
