Hakuo Gakuin is on the verge of closing down due to students transferring to rival school Seishikan after mysterious injuries happening to students who refuse to transfer. To protect the school and its students they hire Kojiro, a member of the Fuma clan of ninjas. After finding out that Seishikan has enlisted the help of the Yasha ninja clan, who had been rivals with the Fuma for generations, Kojiro gains the help of his fellow Fuma ninjas. Even though they are hired to protect the schools, the two rival clans vow to destroy each other once and for all so that only one clan remains.

Rokurou "Rock" Okajima has joined the Lagoon Company, a pirate mercenary group which operates out of Roanapur, Thailand. Despite his initial protests, this filthy slum of depraved souls and merciless criminals now serves as the former salaryman's home. Stranded, with nothing left of his past life but the clothes on his back and his inner morality, Rock is forced to perform jobs alongside the other members of the Lagoon crew. Berated for his lack of spine as he wades through the underbelly of society, he must decide whether to continue on amidst the gunfire and ruthlessness or risk everything he has in an attempt to be free. Whether he chooses the comfort of a familiar land or the freedom of being an outlaw, his decision will have lasting consequences on the crew who gave him a home.
