is a Japanese manga series written by Nisio Isin and illustrated by Yūji Iwahara. It began serialization in Shueisha's Weekly Shōnen Jump magazine in November 2022. Plot summary The plot takes place in the eponymous Cipher Academy, a former all girls' military academy focused on study of cryptography, and focuses on Iroha Irohazaka, the sole boy in his class. While dealing with a spartan homework puzzle on his first day in class, Iroha comes across Kogoe Horagatoge, a student from a different class on the run from Kyora Toshusai, a fellow student of Iroha's and the heiress to a weapons manufacturer. After helping hide her, Kogoe gifts Iroha with a pair of glasses embedded with technology that allows him to see the "hints" to codes that his fellow classmates use to seed control. After winning a cipher-based battle against Kyora, Iroha is thrown into a conspiracy involving 50 billion morg hidden in the academy - a stash of cryptocurrency so valuable that it could end half the wars in the world... or double them.
