Tricked into assassinating his own prospective father-in-law, righteous samurai Raizou Kurima is overwhelmed with guilt. In order to reclaim his honor, Raizou swears vengeance on the lord who gave him those misleading orders. In his pursuit, he is aided by self-proclaimed merchant-of-all-trades Yuuen Usui, who is actually one of the Revengers—assassins who seek justice for the wronged and dispense bloody revenge on their behalf. Tragedy seems destined to follow Raizou as he becomes increasingly intertwined with members of the Revengers. As he begins working as a vigilante alongside them, the complicated web between the corrupt Japanese political elite, the unscrupulous Europeans, and the Revengers gradually reveals itself. The more entangled he becomes in these affairs, the more Raizou realizes that justice is as deceptive as the honor that he sought to redeem.

A variant of Robin Hood in which all the principal characters are teenagers. Several centuries ago in Nottingham County, a cruel and greedy baron by the name of Alwine ordered the destruction of the Huntingtons' castle—from the fire of which Robin and his cousins, Will, Winifred and Barbara, miraculously escaped. The youngsters sought shelter in Sherwood Forest, where, thanks to the wise guidance of the hermit better known as Friar Tuck, they managed to face the difficulties of a life in the wilderness as as well as they could; however, in the forest there lived a fearless group of young bandits, led by Little John. Their first encounter with Robin and his cousins was at first rather stormy, as the two groups fought for the destiny of a young, noble maiden named Marian who had fallen into the hands of the bandits during an ambush. Their bitterness, however, rapidly lead the way to friendship, and Robin and John later realized they were all victims of the same fate. The youngsters thus mutually decided to help one another. Baron Alwine was not merely enemy of the Huntingtons—in fact, a couple years earlier he had forced Little John and his gang to seek protection in the forest to avoid forced labour. He would later seek Marian Lancaster for the secret carved on a cross the girl wore as symbol of her family line. The girl was to be adopted by the shady Bishop Herfort—Alwine's accomplice—who sought to attain the Lancaster's wealth. With all their strength, Robin and his friends were then compelled to fight against the baron's troops, led by Gilbert—a dangerous and fearless knight. When Winifred and Marian were then imprisoned in the castle's dungeons, our heroes tried in every way possible to enter until their ardour was finally rewarded with success. Thanks to his noble heart and heed for danger, Robin became rapidly known as the protector of the poor and oppressed. Beloved and highly esteemed not only by the villagers, but also and especially by the sweet and beautiful Marian he was. The boy who never parted from his loyal, magical bow, endlessly engaged in dangerous and unthinkable missions.
