Chapter 2:
The Garbage Skill “Mana Well” Is Actually Infinite Power
The damp stone bit into Haru’s back. Iron manacles, etched with containment runes, leeched warmth from his wrists and fed a constant, dull drain into the walls. He had lost track of days. The only light came from a single mage-light crystal embedded in the ceiling, flickering with the rhythm of the Grand Barrier far above—the very spell his body was forced to power.
Haru Tanaka, twenty-four years old, former convenience store clerk, now a living battery.
He let his head fall back against the wall. The summoning had been terrifying—a vortex of light, the chanting of royal mages, the searing pain of a magical brand being etched onto his soul. When Archmage Valeria had pronounced his Gift with that cold, clinical voice, the hope in the throne room had curdled into sneers.
“Mana Well. D-rank. A passive reservoir. No spell circuits, no elemental affinity, no shaping potential. Not the Hero.”
D-rank. The bottom of the scale. The brand on his chest, a stylized wellspring rune, still throbbed under his tunic. They hadn’t even bothered to treat it kindly. King Aldric, a man carved from granite and disappointment, had waved a dismissive hand. Valeria had suggested repurposing him. And so Haru had been dragged down here, chained to a siphon array that sucked every drop of mana he produced to reinforce the Grand Barrier protecting the capital city of Asterion. A barrier that, according to the muttering guards, was the only thing keeping void-beasts from overrunning the kingdom.
A useful piece of trash.
Haru’s lips cracked into a bitter smile. In his old life, he’d stocked shelves, dealt with rude customers, and dreamed of something more. Be careful what you wish for.
He flexed his fingers, feeling the faint, familiar tingle deep within—the wellspring of mana that the siphons never quite emptied. At first, he’d been too weak to notice. The drain had left him a hollow shell, barely conscious. But as the days blurred into weeks, something strange had happened. The emptiness never deepened. In fact, the mana inside him seemed… fuller. Denser. Pushing back against the drain with a quiet, relentless pressure, like an ocean pressing against a leaky dam.
Infinite. The thought was absurd. All magic had limits, every mage had a finite pool that needed rest and recovery. That was the fundamental law of this world. And yet, every morning Haru woke feeling no weaker than the day before. Sometimes, when the siphons pulsed harder, he felt a surge of energy rise to meet them, effortlessly, automatically.
He hadn’t told the guards. He hadn’t told anyone. Because if they knew, they’d only find a more efficient way to exploit him. Or worse, dissect him to find the source.
So he waited. Conserving his strength. Feeling the ebb and flow of his own infinite well. Learning, in the silent dark, to feel the texture of mana—both his own and the foreign enchantments woven through the stone around him. The siphon array was a spell like any other, a construct of runic logic and imposed limits. And those limits… he could feel them. Brittle edges. Finite capacities. The way the containment runes on his cuffs trembled whenever his internal mana surged too fast.
If his mana was truly infinite, then any spell trying to contain him was a cup trying to hold the sea.
He just needed the right moment.
Part 2: The Princess’s IntuitionThe heavy iron door at the end of the corridor groaned open. Haru tensed, expecting the familiar, bored shuffle of the jailer with his daily bowl of watery gruel. Instead, soft, measured footsteps approached—lighter, quicker, carrying a presence that made the mage-light flicker.
A woman stepped into the dim circle of light. She wore a simple blue cloak over a practical tunic and leggings, but the silver circlet resting on her chestnut hair marked her station. Princess Elara, second daughter of King Aldric. Haru had glimpsed her during the summoning, standing in the shadows behind the throne, her expression unreadable. She was younger than him, perhaps twenty or twenty-one, with sharp grey eyes that seemed to cut through the gloom.
Those eyes studied him now with an intensity that made him straighten despite his exhaustion.
“You’re still alive,” she said. Her voice was not cold, but thoughtful. “Archmage Valeria’s calculations suggested you would burn out within a month. It’s been seven weeks.”
Haru met her gaze. “Is that a professional curiosity, Your Highness, or a social visit?”
A flicker of something—surprise? amusement?—crossed her face. “Both. Though I admit, I came to see if the rumors were true. The barrier has been… oddly stable. Stronger than before the summoning. The mages attribute it to favorable ley-line alignment, but I’ve learned not to trust convenient explanations.”
She stepped closer, and Haru caught the faint scent of parchment and mint. “May I see your brand?”
He hesitated, then pulled aside the torn collar of his tunic. The D-rank wellspring rune glowed faintly, but around its edges, hair-fine golden lines had begun to spider outward—new markings that hadn’t been there when Valeria had applied the brand. Elara’s breath caught. She reached out, stopping just short of touching his skin.
“Your mana signature is… it’s like staring into a well with no bottom,” she murmured. “I’m not a mage, but I have a minor Gift—Mana Sight. It lets me perceive auras and flows. Most people are candles or bonfires. You…” She shook her head. “You’re the ocean.”
Haru’s heart thudded. She knew. Or at least, she sensed enough to be dangerous.
“Are you here to tell the Archmage?” he asked quietly. “Turn me into a more efficient battery?”
Elara’s grey eyes snapped to his. “No.” The word was immediate, fierce. “My father sees a failed summoning. Valeria sees a convenient power source. But I see a man who was dragged from his world, branded, and thrown in a dungeon without ever being asked what he wanted. That isn’t justice. It isn’t even practical.”
She reached into her cloak and produced a small iron key, its handle wrapped in a dampening cloth to suppress magical alarms. “I’ve spent the past three weeks copying this from the jailer’s belt and studying the patrol rotations. The eastern drainage grate leads to an old cistern that connects to the river tunnel. No runic wards—too old, too forgotten.”
Haru stared at the key. “You’re going to free me.”
“I’m going to offer you a choice,” Elara said. “Stay here and eventually be bled dry by a kingdom that doesn’t value you. Or come with me, earn your freedom on your own terms, and show them exactly how wrong they were.”
“What’s in it for you?”
She smiled—a small, sad expression. “A chance to prove that a princess’s duty isn’t just obeying her father. It’s protecting those her kingdom wrongs.” She met his eyes. “And maybe… a friend. I don’t have many who see me instead of my title.”
Haru looked at the key, then at his chains. The ocean inside him stirred. “I accept. But when we get out of here, I’m going to need you to step back. I’ve been waiting to try something, and it might get… bright.”
Part 3: A Defiant RescueThe key turned with a whisper-quiet click. The manacles fell away, and for the first time in seven weeks, the relentless drain ceased. Haru gasped. Raw mana flooded back into his limbs—not just returning, but rising, a tide that had been barely restrained. The gold spider-lines on his brand flared. The mage-light overhead flickered wildly.
Elara took an instinctive step back. “What’s happening?”
“My mana,” Haru breathed, flexing his hands. Without the siphons, he felt like a dam that had just had its floodgates opened. Power surged through him in waves, so vast that he could feel the stones beneath his feet vibrating. “It’s been building up. I think—I think it’s infinite. When the drain stopped, it all came rushing back at once.”
Elara’s eyes widened, the silvery aura of her Mana Sight glowing faintly around her pupils. “The readings are off the scale. We need to move before the court mages sense this.”
She led him through the dungeon corridors, guiding him past sleeping guards and dormant alarm wards. The princess moved like a shadow, her knowledge of the castle’s secret passages evident in every turn. Haru followed, his bare feet slapping against cold stone, his mind reeling.
Infinite mana. He’d suspected, but now, with the chains off, the certainty was absolute. The power wasn’t just a pool; it was a source that refilled faster than it could ever be used, a self-multiplying cascade that grew more potent with every heartbeat. The sensation was intoxicating and terrifying in equal measure.
They reached the old cistern, a circular chamber with a stagnant pool at its center. A rusted grate in the wall marked the entrance to the river tunnel. Elara pointed. “Through there. The tunnel leads outside the city walls.”
A shout echoed from behind them. Magelight flared. A patrol had spotted their absence.
“Go!” Elara urged.
But Haru turned toward the approaching lights. Three guards, led by a minor court mage whose robes crackled with prepared spells. The mage raised a staff, a binding incantation already on her lips.
Haru didn’t have a spell circle. He didn’t know any incantations. But he remembered the feeling of the containment runes on his cuffs, how they had trembled when his mana pushed back. He focused on the staff, on the delicate weave of the binding spell forming at its tip. His mana wasn’t a shaped spell, but it was energy—raw, neutral, obedient only to will.
He pushed.
Golden light exploded from his palm, not as a bolt or a beam, but as a formless wave. It didn’t cast anything. It simply flooded the binding spell mid-formation, stuffing so much ambient mana into its structure that the runic framework shattered like a glass bottle under a waterfall. The staff splintered. The mage was hurled back, unconscious but unharmed. The guards scrambled, their non-magical weapons useless against a display of pure, overwhelming pressure.
Haru stood panting, his hand still smoking. “That was… inelegant.”
Elara grabbed his arm. “Elegance can wait. Run!”
Part 4: Fragile FreedomThey emerged from the river tunnel gasping, soaked to the bone, outside the eastern wall of the capital. Moonlight silvered the fields and the distant forest. Haru collapsed onto the grassy bank, chest heaving. Elara knelt beside him, her cloak tattered and wet, but her eyes bright with triumph.
“We made it,” she whispered. “They won’t track us easily—the river disperses mana signatures.”
Haru stared up at the unfamiliar stars. Two moons hung in the sky, one large and silver, the other a smaller, distant blue. He was free. Truly, terrifyingly free.
He turned his head to look at the princess who had risked everything for a stranger from another world. “Why?” he asked again. “Really?”
Elara wrung water from her hair, her circlet slightly askew. “Because I’ve spent my whole life watching mages and nobles judge people by the labels on their brands. My older brother was hailed as a genius fire-mage until he was killed by a spell backlash. My younger sister is a healer, cherished and protected. Me?” She gave a hollow laugh. “Mana Sight. A passive Gift. Useless in combat, useless in court. I know what it’s like to be dismissed as a D-rank inconvenience.”
She met his gaze. “When I saw your brand, I saw someone else being thrown away. And when I looked deeper, I saw something they were too arrogant to notice. A Gift isn’t garbage just because it doesn’t fit their tidy categories. And you… you proved that tonight.”
Haru sat up slowly. The golden lines on his chest were fading, but he could still feel the ocean humming beneath his skin. “What happens now? You’re a princess who just freed a prisoner the crown was exploiting. Your father won’t be happy.”
“My father will be furious,” Elara agreed. “But he’s also pragmatic. If we can prove your value—real value, not just as a battery—he’ll be forced to acknowledge it. The kingdom is desperate. The Grand Barrier is our only defense against the void-corrupted monsters that roam the wilds, and it’s been destabilizing more frequently. The court mages can barely maintain it. If you can help with that, and we present it as a planned test rather than a jailbreak, we might just survive this.”
“You want me to stabilize the barrier?” Haru asked.
“I want you to show them what I sensed,” Elara said. “That you’re not a failure. You’re something new.”
Haru looked at her—this sharp-eyed princess with her damp cloak and her impossible scheme—and felt something shift in his chest. Not love, not yet. But the first seed of trust. The first crack in the wall he’d built around himself since arriving in this world.
“All right,” he said. “Let’s go prove them wrong.”
Part 5: The Unstable BarrierThree days later, after a careful campaign of discreet messages and political maneuvering orchestrated by Elara, Haru stood once more in the throne room of Asterion. This time, he was not in chains. He wore a simple tunic and trousers provided by the princess’s attendants, and he stood at her side, facing a roomful of hostile faces.
King Aldric glowered from his throne. To his right, Archmage Valeria’s expression was carved from ice, her silver robes gleaming with protective enchantments. To his left, a cluster of nobles whispered behind raised hands, their brands—A-ranks, S-ranks—glinting with pride.
“You have audacity, daughter,” Aldric rumbled. “Freeing a prisoner, endangering the barrier, and then demanding an audience to present him as an asset rather than a criminal.”
Elara curtsied, her composure flawless. “I acted in the kingdom’s best interest, Father. Haru Tanaka’s Gift was misclassified. He possesses not a finite mana reservoir, but a self-replenishing, effectively infinite source. His presence in the dungeon was not aiding the barrier—it was straining it. The siphons were never designed to handle his output. I have evidence.”
Valeria’s eyes narrowed. “Impossible. Infinite mana is a theoretical impossibility. The Law of Magical Entropy is clear: all sources diminish with use.”
“Then test me,” Haru said, stepping forward. “Right now. Your barrier is flickering, isn’t it? I can feel it from here—the eastern quadrant’s runic lattice is destabilizing. Give me access to the primary anchor, and I’ll prove my worth.”
The room erupted in murmurs. Valeria’s lips thinned. “You can sense the barrier’s condition? Without diagnostic spells?”
“I spent seven weeks connected to it,” Haru said. “I know its rhythms. I know where it hurts. And I know I can fix it.”
King Aldric leaned forward, his granite expression cracking with a hint of intrigue. “And if you fail? If your meddling collapses the barrier entirely?”
“If I fail,” Haru said, meeting the king’s eyes, “you can put me back in chains and drain me dry. But if I succeed, I want a formal place in the Adventurer Corps. Iron-rank. A chance to earn my own standing, independent of anyone’s charity or chains.”
Silence. Then Aldric nodded slowly. “Very well. Archmage, escort him to the Grand Barrier’s anchor chamber. If he destabilizes it, you have my permission to execute him on the spot.”
Part 6: Flooding the RuneThe anchor chamber was a vast circular room beneath the castle, dominated by a towering crystal pillar etched with thousands of interlocking runes. The Grand Barrier’s spell converged here, a web of layered protections that extended across the entire capital. Haru could see the strain immediately—hairline cracks running through the lower runes, pulsing with an ominous violet light. Void-taint, leaking through the degradation.
Valeria stood at the control lectern, her fingers poised over the diagnostic crystals. “The eastern lattice is at forty-three percent integrity and falling. If it drops below thirty, a breach is inevitable.”
Haru approached the pillar, ignoring the cluster of junior mages who watched him with a mix of fear and contempt. He placed his palm against the cold crystal and closed his eyes.
The barrier was a spell. A massive, intricate, ancient spell, woven by generations of mages. Its runes were patterns carved into the crystal, channels for mana to flow. And like every spell, it had limits. Capacities. Safeguards meant to prevent overload.
Safeguards were, fundamentally, constraints. And constraints could be broken.
He reached inward, finding the ocean, and began to release it—not in a flood, but in a controlled stream. Golden light poured from his palm, sinking into the crystal, flowing through the runic channels like warm honey. The cracked runes drank it in. The violet taint hissed and recoiled, unable to withstand the sheer volume of neutral, purifying mana.
The diagnostics on Valeria’s lectern went haywire. “Integrity rising. Fifty-two percent. Sixty. Seventy-eight. It’s… it’s overcharging the safety limiters!”
“Let it,” Haru said through gritted teeth. The limiters were dampeners, designed to throttle excess input. They were the barrier’s protectors—and its weakness. He pushed harder, feeling the dampeners strain, then crack. One by one, they shattered, but instead of causing a cascade failure, the barrier simply… expanded. The runes glowed brighter, the crystal pillar humming with a frequency that made the floor vibrate.
Haru rewrote no spell. He added no new runes. He simply poured so much mana into the existing framework that the framework had no choice but to grow, reinforcing itself beyond its original parameters. The violet taint was scoured clean. The cracks sealed. The barrier stabilized at one hundred percent integrity and then kept climbing, its boundaries thickening, its wards sharpening.
When he finally withdrew his hand, the pillar blazed like a captured sun. The entire anchor chamber was bathed in warm golden light.
Valeria’s face had gone pale. “You didn’t just stabilize it. You… over-reinforced it. The barrier is now six times stronger than its original design specification. The limiters are completely bypassed. This should be physically impossible.”
Haru swayed, not from exhaustion—his mana was, after all, infinite—but from the sheer mental strain of directing such a torrent. “Turns out ‘impossible’ is just a word for ‘nobody’s tried hard enough yet.’”
Part 7: Vindication at CourtThe throne room was silent. King Aldric stared at the projection crystal Valeria had conjured, showing the Grand Barrier’s new readings. The numbers were undeniable. The capital was now encased in the strongest magical defense the kingdom had ever possessed—all thanks to the D-rank failure they had thrown in a dungeon.
“Well,” Aldric said at last, his voice rough with a mixture of awe and chagrin. “It appears we owe you an apology, Haru Tanaka.”
Haru stood straight, though his legs still felt a little wobbly. Beside him, Elara radiated quiet satisfaction. “I don’t need an apology, Your Majesty. I need a chance. Iron-rank, as we agreed. A place where I can learn to control this properly. And”—he glanced at the princess—“official recognition that your daughter acted with foresight, not treason.”
Eyes turned to Elara. The king’s expression softened, just a fraction. “My daughter has always possessed sharper insight than the rest of us. She warned me that the summoning was rushed. She warned me not to discard you.” He inclined his head. “Princess Elara, your actions are officially commended. You saw value where we saw refuse.”
Elara dipped a perfect curtsy. “Thank you, Father.”
Valeria cleared her throat, her icy demeanor cracking with a hint of professional fascination. “The brand classification system may require revision. If Haru’s mana truly is infinite, we are dealing with an anomaly that defies centuries of established magical theory. I request permission to study his capabilities—non-invasively, of course.”
“Granted,” Aldric said. “But Haru Tanaka remains a free agent. Assign him to the Adventurer Corps, provide basic equipment and training, and see what he makes of himself.” He fixed Haru with a stern look. “You’ve earned your chance. Do not waste it.”
Haru bowed, a gesture he’d practiced in the cistern tunnels. “I won’t.”
As the court began to disperse, Elara touched his elbow. “You did it.”
“We did it,” he corrected. “I’d still be in chains if not for you.”
She smiled—a real smile, not the diplomatic curve she’d worn in the throne room. “Then let’s keep helping each other. The road ahead won’t be easy.”
“Nothing worth doing ever is,” Haru said. And for the first time since arriving in this world, he felt something like hope.
Part 8: An Alliance ForgedThat night, Haru stood on a small balcony of the guest quarters Elara had secured for him. The capital sprawled below, lantern-lit streets winding between stone buildings. Above, the Grand Barrier shimmered like a golden aurora, pulsing gently with the rhythm of his own mana. A piece of him was woven into it now, a permanent echo.
Footsteps approached. Elara joined him at the railing, still in her court dress but with her hair down, the circlet absent.
“Couldn’t sleep either?” she asked.
“Too much to think about. New world, new life, new power I barely understand.” He turned to her. “You really believe I can become something here? Something more than a human battery?”
“I do.” She leaned on the railing, looking out at the city. “When I look at you with Mana Sight, I see potential. Not a skill, not a predefined path—just boundless potential waiting to be shaped. The mages think magic is about formulas and affinities. But the old legends… they speak of heroes who wielded raw power through will alone. Will-Shaping, they called it. A lost art.”
Haru filed the term away. “I just pushed raw energy into a spell until it buckled. That’s not art. That’s brute force.”
“Today it was brute force. Tomorrow, with training, it could be precision. Mastery.” She met his eyes. “Promise me something, Haru. Don’t let them define you by what you can’t do. Find what you can do and make it legendary.”
He felt a warmth spread through his chest, different from the surge of mana. “I promise. And you? What will you do, now that you’ve proven yourself?”
She laughed softly. “Keep an eye on the adventurer who just crashed through the kingdom’s magical theories. And maybe learn to fight. If I’m going to be an ally to someone like you, I should be able to hold my own.”
“I’d like that,” Haru said. “Having you by my side, I mean.”
The words hung in the air, more intimate than he’d intended. Elara’s cheeks pinked slightly in the moonlight, but she didn’t look away. “Then we’re agreed. An alliance.”
“An alliance,” he echoed.
They stood together in comfortable silence, watching the golden barrier pulse above the sleeping city. In the dungeon, he had been alone, chained, powerless. Now he had a friend, a purpose, and an infinite ocean waiting to be mastered.
The journey was just beginning.
Teaser for Chapter 3Haru’s first day as an Iron-rank adventurer throws him into brutal training under a disgraced knight, a clumsy first quest, and an unexpected partnership with a jittery healer. But controlling infinite power proves harder than breaking chains, and a minor goblin hunt becomes a lesson in humility, teamwork, and the very real difference between raw strength and true skill.
