On one hand you have Kai, born as the son of a prostitute, who's been playing the abandoned piano in the forest near his home ever since he was young. And on the other you have Syuhei, practically breast-fed by the piano as the son of a family of prestigious pianists.

In the newly formed Shiniki district of Tokyo, Zen Seizaki is a diligent public prosecutor at the Tokyo District Public Prosecutors Office. Assigned to a case involving false advertisement, Zen—along with his assistant officer, Atsuhiko Fumio—investigate Japan Supiri, a pharmaceutical company that had provided fabricated clinical research on the company's new drug. While investigating the file of Shin Inaba, an anesthesiologist connected to the crime, the case takes a dark turn when Zen finds a page stained with a mixture of blood, hair and skin, along with the letter F scribbled all across the sheet. As he investigates further, the case goes beyond Zen's imagination and becomes vastly complex, challenging his sense of justice and his knowledge of the truth. Digging deeper into the investigation, Zen begins to uncover a concealed plot behind the ongoing mayoral election and ties to many people of interest involved in the election and those closer than he thinks. The case grows more severe and propels Zen into an unforeseen hurricane of corruption and deceit behind the election, the establishment of the Shiniki district, and the mysterious woman associated with it all.

Taking place at Winford Academy located in an old town called Helen's Hill, the story is all about knights and the sport of jousting. At this school, students learn how to become knights, ride horses and joust properly. The main character is a young man named Takahiro Mizuno who was training to become a knight and jouster but after suffering an injury he dropped out of the knight program and joined the begleiter (assistant) program instead. Due to his animal handling skills and former experience as a jouster, this makes him a hot commodity. Multiple beautiful girls in the school want him to become their personal begleiter, though Takahiro always refuses their offers. One day a bizarre accident causes his friend, Mio Kisaski, to be challenged to a jousting duel despite her not actually being a knight. Takahiro agrees to become her temporary begleiter, but that ends up only being the beginning of their partnership as she enrolls in the annual tournament.
