Megumi Noda, or "Nodame" is a piano student at Momogaoka College of Music. An extremely talented pianist who wants to be a preschool teacher, she prefers playing by ear rather than reading the music score. She is messy and disorganized. Shinichi Chiaki is Momogaoka's top student. Born into a musical family, he is talented in piano and violin and has secret ambitions to become a conductor. An arrogant multi-lingual perfectionist who once lived abroad in the music capitals of the world as a young boy, he is trapped in Japan because of his childhood phobia of airplanes and the ocean. They meet by accident and sparks fly!

Nao Kanzaki, a student, was blackmailed into joining a "Liar Game" and ended up losing 100 million yen. In order to repay the debt, she enlists the help of Shin'ichi Akiyama, a genius swindler who was only recently released from jail for bankrupting one of Japan's largest scam companies.

It's three years after the events of the original Battle Royale, and Shuya Nanahara is now an internationally-known terrorist determined to bring down the government. His terrorist group, Wild Seven, stages an attack that levels several buildings in Tokyo on Christmas Day, killing 8000 people. In order for the government to study the benefits of "teamwork", the new students work in pairs, with their collars electronically linked so that if one of them is killed, the other dies as well. They must kill Nanahara in three days - or die.
