War is brewing in medieval Japan. Nobunaga, an evil half-demon warlord, is trying to rid the land of Kasumi, Hyuga, and Hagakure, the last remaining ninja schools and only obstacles that stand in his path of total domination over the land. Entrusted with three legendary weapons, three warriors are set out to stop him at all costs. United by fate with a common purpose, these warriors must decide if what they’re fighting for is worth the costs of their lives; for only together will their combined skills overcome evil.
Jubei Kibagami is just a wandering swordsman minding his own business... until fate lands him in the middle of a battle with the terrifying Devils of Kimon! Now the fate of all of Japan lies in the hands of a vagabond samurai, a deadly female ninja and a perverted old monk as they take on an enemy who is, literally, immortal.
Wrath of the Ninja felt like a subpar version of Ninja Scroll on many levels. If you enjoyed Wrath of the Ninja, you should really do youself a favor by checking out Ninja Scroll.
Shuranosuke Sakaki is a swordsman with a reputation; wearing a crest known as the "Scythes of Death", he wanders the land, cutting down anyone who dares stand in his way. After a chance encounter, Shuranosuke is enlisted to rescue the Shogunate's princess from the hands of the vicious Seki ninja clan; but danger is afoot! With undead spirits, multiple ninja clans and powerful warriors standing in his way, Sakaki must use his deadly skills with the blade to rescue the princess, or die trying!
Wrath of the Ninja and Sword for Truth are both somewhat more serious examples of series with Ninjas. The feel of the fight scenes and of the series in general is so similar that if you enjoyed one, you should enjoy the other.
