Honda, Kawasaki, and Suzuki all comprise the elite ninth unit of the Sushi Police—a task force with the sole objective of sniffing out restaurants serving illicit or non-traditional sushi and eradicating them, no matter how insignificant their offense may be. The Sushi Police travel freely around the world in pursuit of these vile criminals day or night, with their strong sense of justice and the World Food-Culture Conservation Organization backing them. No offenders of Japan's traditional cuisine can escape their wrath! During one of their purification missions, the Sushi Police encounter Sara—a hot, young, television reporter out to expose them and the World Food-Culture Conservation Organization for corruption. They interrogate her, but her wiles, skills, and charms allow her to easily escape from their grasp, setting off a chain of events that will lead to the true purpose of the Sushi Police being revealed.

However, due to an unfortunate accident, Haru loses all memories of the summer they spent together, including the promise he made. Five years later, expecting Haru to keep his promise, Ren arrives in Tokyo; but to Haru, Ren is just a random boy claiming to be his brother.
