Season 1

Chairman Nogi suddenly calls low-level employee Kazuo Yamashita into a meeting and gives him an unexpected -- and unwanted -- new assignment.

For his debut kengan match, Ohma calmly faces Yoshitake Real Estate's Lihito, an arrogant fighter with a superhuman vice-like grip.

Ohma thinks he's got the upper hand, but Jun Sekibayashi quickly reminds him: pro-wrestlers are great actors, and they love to put on a show.

Chairman Nogi refuses to enter Ohma into the Annihilation Tournament, but there's another way for him to qualify -- and he'll need Yamashita's help.

While some try to enjoy their time on the luxury liner, others strategize behind the scenes, with one savvy shogi player pulling a surprising move.

In a tense backroom meeting with all the corporate participants, the tournament brackets are finally decided. Tomorrow, the battles begin.

The Kengan Annihilation Tournament kicks off with great fanfare. First up, jujitsu master Cosmo Imai goes up against American brawler Adam Dudley.

Nentendo's Haruo Kohno combines his monstrous size with surprising speed and agility, but riot cop Seishu Akoya's got a secret plan in place.

In a battle between two storied lineages, Raian of the lethal Kure clan takes on Mokichi Robinson, scion of a legendary 19th century kengan fighter.

Ohma goes into his first fight of the tournament with confidence, but he struggles against Ryo Inaba's creepy, unorthodox fighting style.

Kiohzan Takeru looks like he's using MMA moves against “Hell's Angel” Jun Sekibayashi, but his all-out style is how sumo was originally fought.

Gladiators and spectators enjoy a night off. Ohma visualizes his matches against formidable opponents -- including his former master, Niko Tokita.

Ajiro Fisheries' Yoshinari Karo faces Saw Paing Yoroizuka. The fix is in: the match is rigged. But Karo and his harpoon aren't following the script.

Destinyland's Masami Nezu takes on Rei Mikazuchi, the scion of an assassin sect. Ren Nikaido's uncanny move against Setsuna Kiryu backfires.

Lihito's hot-headed and arrogant, but Motor Head Motors' Gensai Kuroki isn't fazed by his taunts. It's youth versus age and the Kaiwan style.

Sen Hatsumi faces Takayuki Chiba, mimicker of other fighters' moves. Hajime Hanafusa enters the ring with orders to kill death row inmate Yohei Bando.

Thai boxer Kaolan Wongsawat fights for his country and sworn liege. Suekichi Kaneda's clearly outmatched, but he's got a cunning and unshakable will.

Naoya Ohkubo is known as the King of Combat, but crowd favorite Agito Kanoh is undefeated with 157 straight wins. It's a matchup for the ages.

The second round begins. At a huge size disadvantage, Cosmo Imai discards his signature grappling moves when facing the monolithic Seishu Akoya.

Seishu Akoya lives by his own code of sadistic justice. On the brink of death, Cosmo Imai has a revelation that puts him back in the fight.

As Ohma faces Raian of the Kure clan, other Kure assassins are on the move outside the ring. The life of Yamashita's eldest son hangs in the balance.

Just when the match seems over, Ohma has a vision and unlocks a new level of his abilities for an epic showdown against Raian.
