A small percentage of adolescents have onsets of special abilities. Yu Otosaka deftly uses an ability that takes over a target's body for five seconds to live the school life of an honor student, and gets accepted into a prestigious high school. Just when Yu is about to live a stable life in high school, a girl named Nao Tomori appears before him...

Yu unwillingly acts together with the student council and runs amok to secure individuals with special abilities. This brings to light why Tomori is determined to fulfill student council duties in face of danger - a past involving a cruel destiny that awaited an ability wielder.

The friends from student council and Ayumi come visit Yu who is hospitalized from his injuries. Among them is Tomori. During his conversation with Tomori, Yu makes a certatin decision.

The decision that Yu makes is to plunder the ability of every last wielder of a special ability on Earth.

It is a choice that provides salvation to every ability-wielder, but at the same time, it is a choice that makes Yu pay a huge price in return.
