In their teenage years, few things can hurt people more than the heartaches that come with unrequited love. Such is the case for Natsuo Fujii, who has found himself entranced by his school's ever-cheerful teacher Hina. Deflated by this unreachable desire, Natsuo humors his friends and attends a mixer. There he meets Rui, a girl whose lack of excitement rivals that of himself. After bonding over their mutual awkwardness, Rui takes Natsuo to her house and asks him to have sex with her, hoping that the experience will stop her friends from treating her like a clueless child. With his hopeless feelings towards Hina still on his mind, Natsuo hesitantly agrees. Equally unfulfilled by their "first times," the two decide to part ways as strangers. However, before he even has a chance to process this experience, Natsuo's father drops a major bombshell: he is getting remarried, and his new wife Tsukiko Tachibana is coming over now to meet Natsuo. As if that was not enough of a shock, her daughters—and, in turn, Natsuo's new sisters—are Hina and Rui Tachibana, the woman he's in love with and the girl with whom he shared his first night. Now, Natsuo must come to terms with the feelings he has for his step-siblings as his eyes open to a darker side of love.

In the 11th year of the Meiji era: the Japanese population is increasingly dissatisfied with the government due to the increasing speed of Westernisation and the ban on samurai. In order to curb the increased rate of crime, the government opens a new prison. The three brothers of the Kumo family — Chuutarou, Soramaru, and Tenka — are entrusted with the duty of transporting these criminals to the new prison, but adventures await them on the way...

When swords were outlawed in the eleventh year of the Meiji Era, the mighty samurai population began to dwindle. Those who rejected the ban on blades rebelled, causing violent unrest to erupt throughout the countryside. To combat the rise in criminal activity, an inescapable lake prison was constructed. Three young men, born of the Kumoh line, were given the duty of delivering criminals to their place of confinement—but could there be more to their mission than meets the eye?

One year has passed after the great battle against the "Orochi" (gigantic snake). Tenka had been paralyzed from the final battle and he took part of the government's human experiment before the battle. Tenka withdrew himself from society, but his younger brothers, Soramaru and Chuutaro, find out the secret past about their older brother.

The brothers fight together again in a battle against the military.
