It slows your pulse down. This is a war story told at drift speed, set in the undersea world of Mer, where the real hook is not the battles but the question nobody can answer: how did tiny Bars suddenly get strong enough to come at Moslem and Agadia at once. Jo and Oz are not chosen heroes, they are two spiritual knights taking monster-culling jobs to eat, and that gap between working stiffs and a continent-scale conspiracy is the whole show. Don't come for spectacle, there isn't much, and the ones who love this know that. Come for the score, which does the heavy lifting the animation budget won't, turning long stretches of open water into something that actually aches. A 1997 curio for people who like their fantasy quiet and their mysteries slow.
Beneath the ocean's surface lies Mer, a underwater civilization caught between three warring nations. Bars, once a minor kingdom, has mysteriously grown powerful enough to challenge its neighbors Moslem and Agadia, spreading conflict across the deep seas. No one understands the source of this sudden military dominance. Jo and Oz are spiritual knights, young warriors who hunt dangerous marine monsters for survival. Their supernatural abilities make them valuable, but the population treats them with suspicion and fear. Regarded as potential threats rather than heroes, they struggle to find acceptance in a world that needs them but despises what they are. When Bars' aggressive expansion forces conflict into their waters, Jo and Oz reluctantly become soldiers in a war they never wanted to fight. As they confront the kingdom's army, they uncover something darker: a malevolent force controlling Bars from within. The pair must decide whether to survive as outcasts or rise as the unlikely defenders of an underwater world that has rejected them.
