Battle of Hisui Bay

Makoto walked the length of Hisui’s harbor, his boots echoing against stone piers. The morning tide slapped rhythmically against barnacle-crusted pilings while gulls circled overhead. The Tempest loomed before him, her dark hull gleaming in the dawn light. He paused at the gangplank, staring up at the vessel. The ship that had been meant to protect Kinto, now turned into an instrument of the Temple’s will.

Lord Kurogane stood on the quarterdeck, inspecting the ranks of Oni-masks. Their armor was immaculate: black lacquered plates etched with silver runes, helmets tucked beneath their arms in synchronization. Pride surged in Makoto’s chest at the sight until Kurogane’s cold gaze fell upon him.

“How old are you?” The question cut through the morning air.

“Twenty-one, sir,” Makoto replied, straightening his back.

Kurogane’s expression hardened. “You don’t belong on this ship. Leave.”

“I am an Oni-mask too,” Makoto argued.

“Leave now, soldier!” Kurogane’s voice boomed across the harbor, causing the surrounding guards to stiffen. “That is an order.”

Makoto clenched his jaw. He wanted to fight, to prove his worth beside these seasoned warriors. Yet behind Kurogane’s harsh tone lay no contempt, only a grim effort to shield him.

Defeated, Makoto turned back down the gangplank. Behind him, Kurogane’s command carried over the water. “Anyone below thirty years old or without an heir does not belong on this ship!”

A handful of others followed Makoto, their faces a mixture of shame and relief. Their unmarred armor gleamed as they filed past in silence, weighed down by the same unspoken question. Why are we being kept from the fight?

Inquisitor Fujiwara Akane waited on the pier, her arms crossed and her dark robes billowing in the sea breeze.

“You should consider yourself being spared,” Akane said, her voice laced with her usual mix of mockery and concern. “Lord Kurogane was prepared to play the hero. He will gladly sacrifice himself for the shogunate.”

“I want to serve the shogunate too,” Makoto replied, the words tasting hollow.

“Why?”

“Because those are my orders.”

Akane surveyed him in silence before turning away. “Suit yourself. Report to the reserve transport or choose another path.” She paused, glancing back over her shoulder. “The Takedas are still demanding your head.”

“I’d rather die in battle to preserve my family honor than die on an executioner’s blade.”

Akane’s lips curved slightly. “Then perhaps you’ll get your wish.”

The morning sun cast long shadows across the churning sea as the allied armada split its formation. Renji stood on the Seaflower’s deck, his hand resting on Pochi’s skull, watching their left wing break northwest toward the approaching Miyako fleet.

Commodore Percy’s flagship, the Muddy River, anchored the right wing while the Waterfall led the left.

“Signal from the commodore,” Erika called out, her telescope pressed to her eye. “Left wing to engage at maximum range. Maintain broadside discipline.”

Renji nodded, keeping his eyes on the horizon. The Seaflower held position with the right wing, tasked with sealing Hisui’s harbor while the left wing engaged the Miyako fleet.

Gio emerged from below deck alongside the three La’Shido Elders. Elder Malin’s white robes whipped in the wind as he joined Renji at the railing, his ancient eyes scanning the distant enemy lines.

To the northwest, the Miyako fleet arrayed itself for battle. Wooden warships stretched across the horizon in a sweeping crescent, their hulls dark against the pale sky. Pagoda towers rose from their decks like tiered temples, crowded with archers and spellcasters, while Guardian Knights stood at the rails with weapons drawn.

The Heavenly Wind, flagship of the Kintoan navy, dominated the center. A massive vessel bearing three decks of artillery and a carved dragon figurehead, it flew the Shogunate’s proudest banners.

The allied left wing bore down on the Miyako center. Leading the formation, the Waterfall swung broadside, her heavy battery swiveling toward the Heavenly Wind.

“All batteries, fire!” Captain Mori ordered.

Heavy cannons erupted in unison. Shells arced through the sky, trailing dark smoke before slamming into the Miyako fleet’s center and right wing. A pagoda ship burst into flames, its tower transformed into a giant torch. Kintoan vessels caught fire, their sails igniting like paper lanterns.

Within minutes, the entire left wing was raining destruction on the Miyako fleet. The ironclads’ guns cycled with mechanical precision, each volley finding its mark with devastating accuracy. Wooden hulls splintered. Masts toppled. The sea churned with debris and drowning men.

Watching their right wing and their flagship being devastated, some clan warrior vessels left the formation and fled. The Miyako fleet’s left wing and reserves turned into a rout as the landward wind carried burning wreckages through their lines.

At Hisui harbor, Kintoan ships lifted their anchors and charged at the armada’s right wing. Renji watched through his glass as the enemy vessels closed the gap.

“They are sailing against the wind,” Renji murmured. “In tight formation, inside the ironclads’ cannon range.”

“Suicidal fools,” Elder Malin muttered. “They’ll burn before reaching us.”

“Bravery doesn’t mean reckless,” Elder Denren added. “A true warrior should weigh the risks.”

The Muddy River’s port side battery erupted in flame and thunder. On the lead Kintoan pagoda ship, the crew barely registered the high-pitched whistle before the first shell struck amidships. The wooden hull exploded inward, sending massive splinters through the crowded deck. A second impact snapped the mainmast, listing the ship sharply as water rushed through the shattered hull.

Renji watched through his spyglass as the Kintoan formation disintegrated. The front rank of pagoda ships became floating debris fields, their crews thrown into the churning sea. Some tried to swim toward the ironclads, only to be cut down by rifle fire from the Dorean marines.

Another broadside followed. Kintoan arrows, ballista bolts, and magical blasts splashed harmlessly into the water, falling dozens of meters short of the ironclads.

“They can’t reach us,” Commander Silvio observed.

“And we won’t let them close,” Renji replied.

Then a single vessel broke ahead of the rest, moving at extraordinary speed. Cannon shells struck an invisible barrier around it, producing bright bursts of light but failing to pierce the shield. Lord Kurogane stood on the deck, holding a tower shield and sword, his black Oni-mask armor catching the sun.

“The Tempest,” Renji breathed, his blood running cold. “I helped design her. She runs on a mana engine and a yang barrier.”

“Can we destroy it?” Erika asked.

“Yes,” Renji said. “She’s pushing maximum speed and shielding simultaneously. Her fuel won’t hold.”

As the Tempest entered Gatling gun range, null-steel rounds began tearing through the flickering barrier. Cannon shells slammed directly into the deck. Seconds later, a direct hit detonated the mana batteries, engulfing the ship in a roaring fireball. The Tempest disintegrated into burning wreckage.

Thrown into the sea, Kurogane stripped off his helmet and armor to keep from sinking. Sword still clutched in hand, he swam toward the allied flagship through a hail of gunfire.

The Seaflower drew near, and Renji threw a rope ladder over the rail. Kurogane seized it and hauled himself aboard. He stood unsteadily on the deck, blood pooling beneath his feet, but his eyes burned with unwavering resolve.

“Mad Magus,” he growled, raising his sword with trembling hands. “Fight me! Give me an honorable death!”

“You have enough honor already,” Renji said steadily. “Drop your weapon and surrender.”

Kurogane lunged forward with a final cry. “Long live the Emperor!”

A sharp volley of rifle fire cut him down. Kurogane collapsed backward, his sword clattering against the deck, eyes staring up at the empty sky.

Renji knelt beside the fallen commander and gently closed his eyes. “Rest now,” he murmured. “Your war is over.”

Across the bay, the surviving Kintoan ships retreated toward the harbor, demoralized and broken.

From the deck of a reserve transport ship, Makoto watched the distant shape of the Seaflower. Though he could not see his friend across the water, he felt his presence all the same.

The world had changed, the war was joined, and two childhood friends found themselves on opposite sides of a conflict that would decide the fate of their homeland and the world itself.
