Shigurui: Death Frenzy (Funimation)

Years before the tournament, Gennosuke Fujiki was the stoic star pupil of the Kogan dojo, and Seigen Irako was a brash young samurai seeking fame and an audience with the dojo's master. After disgracing Gennosuke on his own turf, Seigen must next face a superior foe to earn the right to meet the sensei. The battle is the most difficult of his young life, and a dark secret waits for him at the journey's end.

Once a year, Kogan awakes from his death-like slumber to oversee his dojo. Locked in a decaying state, the master demands to know which of his samurai is worthy of the Kogan legacy. Seigen and Gennosuke are the most likely candidates, but no one is sure which swordsman is best suited to give their demented leader what he desires. In the end, Kogan himself devises a devious challenge to clarify the situation.

Two damaged warriors share a twisted and violent past. Now they must face off within a brutal samurai tournament arranged to satisfy the bloodlust of a cruel tyrant overlord. The disfigured legends of the blade must summon the strength for one last battle - a final lesson in the artistry of violence where nothing is more beautiful than the kill.
