Plot Elements

 * The story takes place in a world without fish, where the Republic and the Empire has long battled over control of sushi in a war known as the Sushi Struggles.
 * In this world, sushi is created by mysterious creatures known as "sushi sprites", and the people who pledge with them to fight (by throwing the plates used to serve the sushi) are known as "sushi strikers".
 * Following the defeat of the Republic in the Sushi Struggles, the empire forbids the discussion and consumption of sushi within the borders of the subjugated Republic.
 * Musashi is an orphan growing up in the republic.
 * One day, while attempting to gather food for hungry children in the orphanage where Musashi grew up, Musashi comes across a sushi striker named Franklin and his partner sprite, Ara-o.
 * Although Musashi initially hates sushi due to losing both their parents in the Sushi Struggles, their extreme hunger forces them to accept an offer from Franklin to try out some sushi.
 * Finding it the greatest food ever, Musashi resolves to spread the word of sushi to everyone and asks Franklin to follow them home to feed the children as a first step. Before they can return home, however, Franklin and Ara-o are captured by imperial general Kodiak and taken away for interrogation.
 * Alone and hungry once more, Musashi hears a distant voice, that leads them to a nearby shrine where their hunger can be satiated.
 * The voice encourages Musashi to eat the sushi that is produced from the shrine. After doing so, the voice reveals itself to be Jinrai, a sushi sprite in hiding who is highly sought after by the Empire; by accepting the sushi, Musashi unknowingly pledges themself with Jinrai, and the two agree to band together in order to rescue Franklin and spread the good word of sushi.
 * Along the way, Musashi and Jinrai encounter members of the Sushi Liberation Front, a resistance force opposing the Empire's subjugation and its hoarding of sushi.
 * Musashi agrees to join the Sushi Liberation Front and is able to drive Kodiak's forces out of Republic territory.
 * Pressing their advantage into Imperial territory, the Sushi Liberation Front eventually reaches Fort Fugu, an Imperial stronghold being held by their top general, a legendary sushi striker named Tiburon.
 * As Musashi faces Tiburon, however, Tiburon unleashes his ultimate technique known as Sushido, a way of consuming sushi in a manner so poetic it freezes enemies in place. While frozen, Tiburon reveals that he is, in fact, Musashi's father Jubay, and that Jubay had defected from the Sushi Liberation Front once he had learned of a dark secret within; this had also led Musashi's mother to throw herself beyond the great shrine gate where sushi came from in despair.
 * Once Tiburon leaves, Musashi confronts Masa, the leader of the Sushi Liberation Front, on the matter, and is incensed to learn that the soldiers of the Sushi Liberation Front are trained to discard the rice and eat only the tastiest part of the sushi, in order to improve their abilities.
 * Finding this to be a travesty, Musashi challenges and defeats Masa for the leadership of the Sushi Liberation Front, declaring that sushi must be respected and consumed in its entirety.
 * Soon after, Musashi learns of the location where Franklin is kept prisoner.
 * Resolving to rescue Franklin, Musashi heads alone to the distant facility where Franklin is held prisoner. There, Musashi discovers that it is a torture facility, where prisoners are force-fed an endless stream of wasabi.
 * After defeating Kodiak, who had been reassigned there after losing the Republic's territory, once more, Musashi is able to rescue Franklin, but due to being subjected to extensive torture, Franklin is no longer able to continue being a sushi striker; in turn, Ara-o asks Musashi to pledge with it in order to continue Franklin's dream that Musashi had inherited.
 * In doing so, Musashi masters their own form of Sushido, and is able to challenge Tiburon in combat once more.
 * The Sushi Liberation Front is able to breach the heart of Imperial territory, and Musashi is able to defeat Tiburon in combat.
 * Tiburon is forced to admit defeat, and after rejoining the Sushi Liberation Front under his former name of Jubay, he tries to convince the emperor Octavius to surrender peacefully.
 * The child emperor, having been traumatized by the fact that he had long been denied sushi by his own parents, goes insane, being completely consumed by his desire to eat all sushi in existence.
 * After a long struggle, the emperor is defeated, and despite Musashi attempting to make a peace overture by sharing a plate of sushi with him, the emperor chooses to depart to, according to Jinrai, "the place where sushi comes from".
 * With the emperor defeated, the land is at peace once more, and the people of the land, in both the Empire and the Republic, are free to enjoy sushi.
 * Jinrai finally reveals to Musashi that sushi had originally came from the fish in the sea, but due to human activity, the fish slowly became extinct, and were reincarnated into sushi sprites. The sushi sprites are able to maintain their strength and continue to produce sushi through the people's appreciation and gratitude for sushi; values that Musashi must treasure and cherish every time sushi is consumed.
 * The story ends with Musashi and Jubay living out their lives together in peace, hoping that someday, Musashi's mother will return from her disappearance, after which they can become a family once more.
