Nagisa Shiota

Nagisa Shiota (潮田 渚, Shiota Nagisa) is a student in Korosensei's class 3-E of Kunugigaoka Junior High School and the protagonist of Assassination Classroom.

Appearance
Nagisa has blue eyes and short, blue hair with some of it sticking out the sides of his head. His uniform consists of a waistcoat worn over a dress shirt with rolled-up sleeves and a black tie, as well as wrist bands, dress pants, and dress shoes.

Plot
After homeroom is started by Korosensei, Shiota Nagisa gives the command for the class to stand. They all draw their guns, aim and fire at Korosensei while he takes the register. Nagisa listens to the creature lecture the class on their supposedly simplistic plan and demonstrates the effect the special bullets have on him if hit, much to Nagisa's astonishment. Nagisa, along with the rest of class 3-E tidy up the classroom under Korosensei's instructions.

He is present in the class after where Kayano Kaede whispers to him, pointing out the permanent crescent moon in the sky causing Nagisa to remember both the destruction of the moon and the meeting and introduction of the culprit. This happened along with Karasuma from the ministry of defence both explaining and actively showing what their future jobs will be, along with revealing the 10 billion yen reward.

Later, while thinking about how the students of class-E aren't normal students, Terasaka, Yoshida and Muramatsu approach him about working on an assassination plan, which he agrees to do with them.

Trivia

 * Nagisa is the first character other than Korosensei to speak in the manga giving the class of assassins the order to stand and fire.
