The comedy doesn't announce itself, it just ambushes you while you're trying to follow what should be a straightforward hero's journey. Nike and Kukuri stumble through a world that treats their quest like a game nobody explained the rules to, and the show finds endless hilarity in that gap between epic fantasy setup and the chaotic reality of actually saving the world. The monsters aren't obstacles to defeat, they're people to negotiate with, befriend, or accidentally insult while trying to recruit them, and that shift from combat to conversation is where the show's real heart lives.
Nike never asked to be a hero, but he and Kukuri, a sweet and innocent heroine, are back on the road to save the world from the evil King Giri. Kukuri must seek out the monsters of each territory and win them over one at a time. Nike has to gain the recognition of the Four Kings of Nature and gather their swords of Wind, Water, Earth and Fire. Along the way they meet odd monsters and eccentric characters in a comic fantasy adventure, as the pair try to live up to the roles of hero and heroine.
