Code: Breaker

One rainy night, high school student Sakura Sakurakoji sees people being burned alive. At school the next day, she meets new transfer student Rei Ogami, the boy she believes was with the burning people. Sakura then resolves to uncover Rei's involvement.

Sakura wakes up in her own bedroom after being found outside the night before. Fearful of Ogami, she becomes protective of Aoba, who mistakes Sakura's actions for unfriendliness. Sakrura calls Ogami out to get to the bottom of the events in the park.

Ogami and Sakura walk to school together, so that they can keep a mutual eye on each other. Not everyone is happy with the attention Sakura is paying Ogami, however. Later, Sakura accompanies Ogami to one of his jobs, and is surprised by what she sees.

Ogami is given his next assignment by the Eden council. Toki picks up Sakura to walk to school, claiming that he is Ogami's friend. Ogami catches up, and starts fighting with Toki, but Sakura stops them both. Toki tours Sakura and Ogami's school.

Ogami, Toki, and Sakura attempt to infiltrate a government-run facility, and encounter two large men with their own special abilities. They locate Diet member Tabata, their target, and are about to carry out their mission when a new secret is revealed.

Toki has a breakfast meeting with the Prime Minister. On their way to school, Sakura and Ogami run into Rui Hachioji, who has a message for Ogami. Sakura urges Ogami to open up and befriend the others in their class, but the class has a surpise of its own.
