According to legend, there is a group of superpowers who call themselves "CODEBREAKER". In such a large city, they use their abilities to impose extrajudicial sanctions on those criminals who have exploited loopholes in the law. Some people say that they are righteous partners who are chivalrous and righteous, while others say that they are extremely vicious and tyrannical, but few people have actually seen them. Sakura Koji Sakura (voiced by Hikasa Yoko), a young lady with a gangster background, happens to be one of them. The identity of the extrajudicial sanctioner must be kept absolutely confidential, so the operation to kill Sakura was launched. Unexpectedly, Sakura is also a superpower, and is a super rare species that can invalidate all superpowers. So, Sakura's special life with these superpowers began. In the process of solving the incident, Sakura's belief in justice and the law began to waver, and at the same time, her mysterious life slowly surfaced. In addition, she also developed a subtle relationship with Okami Zero (voiced by Nobuhiko Okamoto), one of the extrajudicial sanctioners.
