Story
TV series — Spring 1992, 23 episodes, Finished.
When Harimanada makes his grand entrance into the world of Sumo, he causes complete uproar throughout the entire arena. The novelty headmask is clearly not a good idea but not content with just ruffling the feathers of all the spectators, he sends the the entire Sumo Association into a frenzy when he arrogantly declares that he will surpass the legendary Futabayama's consecutive run of 69 victories. Should he fail to achieve such a feat, he will immediately retire all together.
