A continuation of the story of the postwar years in the Japanese Inland Sea. Now a decade has passed. Two friends meet and decide to look for the beautiful girl with whom they went to school as children.
Lewd, long-haired karate kid Kotaro Shindo spends his days causing amok at the prestigious Tsurugamine Academy, until the Disciplinary Committee decides enough is enough, and puts a bounty on his luscious locks. Meanwhile other sinister forces are working in the shadows to put Kotaro to use for their own ends.
Kabamaru is a young boy raised and trained by his grandfather as a ninja. After the sudden death of his grandfather, he starts living with Mai, his grandfather’s mistress, who is a school director. He is asked to help out on struggles against other schools, as he is master of the ninja mystical arts. As time passes he will make lots of friends as well as enemies, and fall in love with Mai.
Jo has just come back to Japan for the funeral of his parents, who were killed in tribal warfare in Africa where the family had been living throughout most of Jo's life. Once the funeral was over, he missed the boat that was going to take him back home, and, because of an altered itinerary, he ends up stopping in a town for awhile -- striking up an acquaintance with a teenager and her grandfather when he captures their runaway horse. He would have been glad to leave after the proper amenities were completed, but the girl's journalist brother is murdered -- he was getting too close to wrapping a major news story. At that point, Jo and a friend cannot easily drop the matter as though nothing had occurred, and the two start to track down the source of the trouble -- a factory that makes poison gas for Third World buyers. Now their task is to dismantle the operation, prevent one train shipment from arriving at a transfer point, and find the journalist's killer.
