Gokudou is a show that makes fun of every fantasy adventure trope the moment it acknowledges them. The protagonist is a complete idiot with zero heroic instincts, and the plot doesn't care enough to punish him for it, instead, it just keeps throwing escalating chaos at him and watching him stumble upward anyway. There is no grand story here, just a speeding comet of absurdity that trusts you to laugh at the wreckage instead of asking for it to mean something.
Gokudou stumbles into fortune when he filches what he thinks is a valuable gem from a traveling fortuneteller. The "gem" cracks open to reveal a genie trapped inside, and the creature begrudgingly offers him three wishes. Problem is, Gokudou's impulsive and lazy, so he wastes them almost immediately. What he does manage to score is a legendary fire sword that answers his call from anywhere in the world, but even that windfall doesn't stop the universe from kicking him around. Constantly broke and perpetually unlucky, Gokudou bumbles through a fantasy world where nothing goes according to plan. His newfound genie companion proves just as much a nuisance as a helper, shape-shifting into whatever form creates the most chaos. A sword-wielding woman named Rubette crashes into his life chasing her own adventures, dragging Gokudou along whether he likes it or not. Between monster hunts, magical mishaps, and his own pathetic decision-making, Gokudou somehow survives each ridiculous situation. This is fantasy comedy for people who enjoy watching selfish protagonists get exactly what they deserve: a never-ending string of absurd, hilarious disasters.
