Ingrid felt pushed back by the Water Serpent, as she summoned flames to counter the attack.
Black Flames counter the Water Serpent, as she looked at Leo, more interested.
Ingrid's black flames clawed through the water serpent, steam hissing between them as the two forces struggled for dominance. She skidded back a step, boots grinding against concrete, eyes gleaming with predatory excitement.
Leo winced, one hand briefly dipping to his groin as he exhaled sharply.
"Tch… damn whiplash."
Kurenai, mid-clash with Suiren, heard that and nearly stumbled. How is he still making jokes right now!?
Ingrid raised an eyebrow, grin widening.
"Oh? Haven't seen a Taimanin react like that before," she purred, tilting her head, watching him with growing curiosity.
"Most of your kind either charge me head-on… or pray."
Leo rolled his shoulders, forcing himself upright. His sword shifted back into a ready stance, the nanoblack-metal rippling with the Blacklight virus.
"Well, I'm not most Taimanin."
His eyes flashed—not demonic, not corrupted—just sharp, a predator glint hidden behind a kid's frame.
Ingrid hummed, flames dancing up her blade.
"Mmm… you really are interesting. Stronger than you look. And that technique—water twisting like a serpent? That's not normal Taimanin ninjutsu."
Leo grit his teeth. "You talk way too much."
"Oh, sweet boy…" Ingrid's smirk deepened, tone dripping with amusement.
"That's because I'm enjoying this."
She flicked her sword, black flames roaring out in a crescent.
Leo dashed through it, Virus armour flaring for a split second as he countered—
WHAM!
Their blades collided again, shockwaves cracking the ground.
From above, Ayame saw the explosion of water and flame smashing against each other and muttered,
"Damn… Ingrid isn't even using half her real power yet. And Leo's keeping up?"
Meanwhile, James' voice echoed in Leo's head.
'Careful—she's testing you. And the more interested she gets, the more trouble we're in.'
Leo grimaced.
'I noticed! I don't want to be her new toy collection.'
Ingrid leaned in close against the blade lock, her breath hot, smile wicked.
"Come on, little serpent… show me more."
Meanwhile.
Kurenai was blocking Suiren's attack, trying to break through whatever mind control the Taimanin was under.
She knew she was missing for a few months, which in their line of work either meant death, sex slave or mind controlled.
She kicked Suiren to the side, but her meat glided away, as she was surprised.
Suiren went for a stab as she moved her sword with quick reflex, and Kurenai stopped it.
Kurenai was pushed back as she looked at her. "Looks like you haven't forgotten your water sweat techie Senpai".
Suiren looked at her as she blushed back. "And you've gotten rusty, even though I don't know why I know that"
Suiren's blade trembled against Kurenai's, sparks flicking between them as the younger Taimanin pushed with unnatural force. Her expression wavered—anger one second, confusion the next—like two minds fighting for the steering wheel.
Kurenai gritted her teeth and steadied her stance, sliding back on the dock from the sheer pressure.
"Suiren… you do remember. Your body does. Your instincts do."
She twisted her wrist, deflecting the stab just enough to give her a breath of space.
Suiren stumbled forward from the redirected momentum, boots skidding. Her cheeks tinted pink—not out of desire, but a faint echo of embarrassment.
"Why… why do I know that you kick too wide with your left…?"
She pressed her fingers to her temple. "Why do I know how you move?"
Kurenai's heart clenched.
She's fighting it. She's really fighting it.
She stepped forward, but not to attack—
—to test.
Her blade swung in a classic arc. Slow. Familiar.
Suiren parried it automatically—perfectly—her eyes widening at her own reaction.
Kurenai smiled softly, despite the chaos around them. "See? That technique… Water Sweat Form Three. I helped you make that when you couldn't hold a sword straight."
Suiren blinked. Her free hand trembled.
"I… I don't… remember training."
Her voice cracked. "I remember… a chair. A room. Chains. Pain. And then—nothing."
Her eyes flashed red for a moment—
—and her body lunged again, mind control reasserting itself.
Kurenai swore and blocked just in time, arms rattling from the force.
"Damn it—Suiren! Fight it! I know you're in there!"
Suiren's lips curled into a warping, forced smile.
Her voice sounded like hers… but strained, like something was puppeting her from behind.
"I… am… fighting…!"
Her arms shook violently.
"help… me—"
Then her expression snapped back to cold, obedient emptiness.
She swung again with brutal efficiency.
Kurenai's eyes hardened.
If I don't break the control soon… she'll tear herself apart.
She flowed back into motion, blocking and parrying with increasing urgency, looking for an opening—not to kill, not even to disable—
—but to save her.
Meanwhile on the other side, as Leo and Ingrid kept the clash of water and fire
As Ayame took bullets on the flesh Dolls
Ingrid blocked another strike of Leo as she looked at him. "Nice try, that's almost hit me".
Then she saw Leo's arm morph; his free hand got covered in the Black light as it turned into claws, as it tried to Jab into her.
She missed the blow by a half-second, as a few of her hair strands fell to the ground.
Ingrid flicked away the last falling strand of her hair with a casual swipe of her fingers.
"Close, boy. Another inch and I might've had to punish you for ruining my looks."
Leo landed lightly, sword raised, Blacklight claws humming with energy.
He narrowed his eyes. "Something's been bugging me this whole fight…"
Ingrid tilted her head, amused.
"…how do you know I'm Fuuma? I never transformed, never used a Demon Mark—hell, I haven't even said the name of my clan."
She smirked, licking her lips like a wolf who found a surprise treat.
"Oh, that's easy."
Leo tensed.
Ingrid lifted a finger and traced a lazy circle in the air.
"I can smell it."
Leo blinked. "Smell—?"
"Fuuma blood has a very particular… aroma." She inhaled deeply, her eyes glowing faintly red.
"Old contracts. Forbidden pacts. A hint of incubus magic… and a whole lot of suppressed potential. You reek of it."
She grinned, wicked and knowing.
"And that's before we even talk about the other scent clinging to you."
Leo felt James and Alex stir in his head.
'Oh great,' Alex muttered. 'She sniffed the virus.'
'Or she wants to sniff you,' James deadpanned.
Leo ignored them.
"What do you mean 'other scent'?" he demanded.
Ingrid gave a soft laugh, stepping toward him, flames flickering off her blade.
"Little Fuuma…"
She leaned in just a fraction, her breath warm with infernal heat.
"…you're carrying something in your body that isn't from this world. Something ancient. Something wrong."
Her smile sharpened.
"And as for your real question—how did we know three Taimanin would come?"
Leo tightened his grip on his sword.
Ingrid winked.
"Why should I tell you?"
She lifted her sword, demonic fire roaring to life.
"This isn't a video game. You don't get a villain monologue just because you asked nicely."
She lunged.
The dock exploded in flame.
Leo moved his sword as he said in his mind. 'Water Arts 10th Form: Constant Flux'.
Leo moved his sword in a constant, flowing attack that kept building momentum and strength as the water energy around the blade solidified. He made a downward swing, and as a water Dragon materialised, Ingrid moved out of the way.
As Leo moved backwards, she was confused why he did this, but then she saw the Dragon going for the Flesh Dolls that were starting to surround, that of Ayame.
Ingrid then blocked a claw attack from Leo, making sure she didn't distribute the attack.
Ingrid's eyes widened—just a little.
"Tch—smart," she muttered.
The water dragon roared past her, its body coiling and surging with relentless force as it slammed into the Flesh Dolls surrounding Ayame. The impact was brutal. Taima-infused water tore through warped flesh, severing tentacles and pulverizing bodies that screeched before dissolving into steaming sludge.
Ayame didn't waste the opening.
She steadied her rifle, breath calm despite the chaos.
"Thanks for the assist."
Bang.
A Taima round pierced straight through the core of a Doll that tried to reform, dropping it instantly.
Back near the docks, Leo skidded backward across the concrete, boots scraping as Ingrid intercepted him. Her Sword slammed against his claw with a shriek of metal and demonic flame.
"So you weren't retreating," Ingrid said, teeth bared in a grin. "You were thinking."
Leo twisted his wrist, redirecting the force and sliding past her instead of meeting it head-on. Water rippled around his feet as if the ground itself had turned fluid.
"I don't need to beat you," he shot back. "I just need to stop you from interfering."
Ingrid laughed, genuinely amused now.
"Oh, I like you. Most boys your age would be shaking."
She swung again—fast, vicious—but Leo flowed with it, his movements smooth and continuous, each step feeding into the next.
'Constant Flux isn't about power,' James's voice echoed in his head.
'It's about never letting the enemy set the pace.'
Leo ducked under a flaming arc and countered, his blade tracing a spiraling cut.
"In that case," Ingrid said, blocking with her sword as steam hissed between fire and water, "let's see how long you can dance."
She pushed him back with a surge of black flame, forcing Leo to slide several meters before he dug in, water bursting beneath his feet to halt the momentum.
Across the battlefield—
Kurenai gritted her teeth as Suiren disengaged again, gliding across the ground like flowing silk.
"She's adapting," Kurenai realized. "She's not just being controlled—she's being guided."
Suiren hesitated for a split second, her grip trembling.
Kurenai saw it.
"Suiren!" she shouted. "You're still in there—fight it!"
For just a moment, Suiren's eyes flickered.
Back with Leo—
Ingrid noticed it too.
"Oh?" she purred. "Looks like your friends might spoil the fun."
Her gaze sharpened, demonic aura flaring.
"Guess I'll have to get serious."
Flames erupted behind her, forming jagged, wing-like shapes.
Leo swallowed, tightening his stance.
'Alex,' he thought.
'How bad is this about to get?'
Alex's voice was calm—but grim.
'She's stopped playing. Adjust your odds—down to forty percent.'
Leo exhaled slowly.
"Figures," he muttered, raising his blade as water surged higher around him.
"Good thing I don't fight alone."
The battlefield trembled—fire, water, bullets, and will colliding as the real fight began.
Leo then put away his sword. "Fuck it".
Ingrid was confused. Then she saw the Black light Viruses go through both of Leo's hands as he made the Claws in both arms.
'Time to fight like a Prototype and not a Ninja'.
Ingrid's grin froze.
Leo let the sword clatter against the concrete, water aura dissipating as the Black Light Virus surged instead—veins of crimson and obsidian crawling over both arms. Bone shifted. Muscle rewrote itself. Blades didn't form so much as grow, jagged and alive, hooked claws unfolding from his forearms like predatory wings.
The air pressure changed.
Ingrid took half a step back before she caught herself.
"…So that's it," she said, eyes gleaming. "You stopped pretending to be human."
Leo rolled his shoulders once. The motion made the blades flex, wet and organic.
'Prototype combat mode,' Alex noted calmly in his head.
'No breathing forms. No restraint. High regeneration, high consumption.'
James added, 'In short—go wild, but don't black out.'
Leo exhaled. His voice came out steadier than he felt.
"Yeah. Got it."
He vanished.
Not a ninja dash—no footwork, no technique. Just raw acceleration, the Black Light throwing his body forward. Ingrid barely managed to bring her sword up before Leo slammed into her guard, claws screeching against demonic steel.
The impact sent shockwaves across the dock.
Ingrid skidded backward, boots carving grooves into the concrete. She laughed, breathless.
"Oh, that's cheating—!"
Leo didn't let her finish.
One claw split into a whip-like blade mid-swing, snapping toward her waist. Ingrid twisted, flames erupting to deflect it, but the blade kept moving, splitting again, reforming, adapting.
She barely cleared it.
"Adaptive biomass," Ingrid muttered. "You're not just Fuuma… you're a walking weapon."
Leo landed, crouched low, claws digging into the ground.
"Yeah," he said flatly. "That's kinda the problem."
Behind them—
Kurenai felt it. The shift. The wrongness.
"…Leo," she whispered, half in awe, half in fear.
Ayame's voice crackled through comms from the rooftop.
"Multiple Flesh Dolls neutralized. But—Leo's vitals just spiked hard."
Ingrid straightened, black flames flaring brighter, her interest now razor-sharp.
"Careful, boy. Fight like that too long and you won't come back."
Leo's eyes glowed faintly red as he raised both claws.
"Then I'll just end this fast."
He lunged again—this time not as a ninja, not as a demon—
—but as an apex predator, and the dock exploded into motion as fire and Black Light collided head-on.
The dock became a warzone.
Ingrid met Leo head-on, black flames roaring as she swung her sword in a wide arc meant to bisect him. Leo didn't dodge—he caught it. One claw locked around the blade, biomass hardening instantly to resist the hellfire, the other claw slamming forward in a brutal cross aimed at her ribs.
Ingrid twisted at the last second. The blow still clipped her, sending her skidding sideways, boots sparking as she carved a trench through stacked crates.
She laughed again—but this time there was strain in it.
"Ridiculous… You're adapting faster than I am."
Leo didn't answer. He was already moving.
He split—literally. Tendrils burst from his back, anchoring him to the ground as his main body lunged forward, claws reshaping into long, scythe-like blades mid-swing. Ingrid blocked one, but the second curved around her guard, grazing her shoulder and tearing cloth and skin alike.
Black blood hissed as it hit the ground.
Ingrid clicked her tongue. "So that's how it is."
She raised her free hand, black flames compressing—not expanding—until they collapsed inward with a sharp crack. The fire condensed into a lance of pure heat, which she drove straight at Leo's chest.
Leo crossed his arms.
The impact detonated in a blinding flash.
Smoke billowed outward, the dock shuddering from the force. For half a second, no one moved.
Kurenai felt her heart stop.
"…Leo?"
The smoke tore apart from the inside.
Leo stepped forward, chest partially caved in—then rapidly knitting itself back together, flesh crawling, bones snapping back into place. His breathing was heavier now, jaw clenched.
'Regeneration cost is rising,' Alex warned.
'You're burning biomass faster than expected.'
'Yeah,' Leo thought grimly. 'I feel it.'
Ingrid stared, wide-eyed for the first time.
"…You took that on purpose."
"To see if it'd kill me," Leo replied. "Guess not."
She grinned sharply. "You Fuuma really are monsters."
Across the dock—
Kurenai finally broke through.
Suiren lunged again, movements sharp but uneven, like a marionette with tangled strings. Kurenai caught her wrist, twisted, and slammed an elbow into her solar plexus, then drove a palm strike into her chest—not to kill, but to disrupt.
"Wake up!" Kurenai shouted. "You're not his weapon!"
Suiren staggered, clutching her head, eyes flickering.
"I… I—"
Tendo snarled from behind her. "Useless!"
He raised a device in his hand—but it shattered mid-air as a sniper round tore through it.
Ayame's calm voice followed a second later.
"Hands off, creep."
The Flesh Dolls began collapsing one by one as Ayame systematically eliminated their control nodes.
Back with Leo—
Ingrid rolled her shoulder, flames flaring brighter, darker.
"You're strong, kid. Strong enough to be dangerous."
She planted her sword into the ground.
"But you're still inexperienced."
The ground beneath Leo erupted in black fire, pillars of heat forcing him upward. Ingrid followed, wings of flame unfurling as she launched herself after him, blade raised for a killing blow.
Leo twisted mid-air.
His arms reformed again—this time into massive cleaver-like blades, heavier, brutal. He crossed them and slammed downward, releasing all the stored kinetic force at once.
"BLACK LIGHT—CRASH!"
The collision hit like a meteor.
Fire and biomass exploded outward, the shockwave tearing apart the dock and blowing both combatants in opposite directions.
Leo hit the ground hard, skidding, rolling, finally stopping on one knee. His claws retracted slightly, breathing ragged now.
Ingrid landed across from him, cape torn, one knee down, sword cracked.
For a long moment… neither moved.
Then Ingrid laughed softly.
"…Heh. If we keep going, you'll either die—or lose yourself."
She stood, black flames dimming.
"And that wouldn't be fun."
Tendo shouted in fury. "Ingrid! Finish this—!"
She didn't even look back.
"No."
She glanced at Leo one last time, eyes sharp, assessing.
"Grow stronger, Fuuma boy. Next time, I won't hold back."
With that, black fire swallowed her whole—and she vanished.
Silence fell over the dock.
Leo let his claws dissolve, collapsing to one knee as the Black Light receded.
'You okay?' James asked.
Leo exhaled shakily.
'…Yeah. Barely.'
Kurenai rushed to his side, grabbing his shoulders.
"Idiot! Do you have any idea how reckless that was?!"
Leo looked up at her, tired grin forming.
"Mission's not over yet, Senpai."
Behind them, Tendo was backing away—alone now.
And Leo's eyes locked onto him.
"Now," Leo said quietly, standing back up, "it is."
Tendo looked at the situation as he spoke. "Nope".
As he ran, seeing this Leo rushed at him, and then his path was blocked by the flesh Dolls, as Leo was busy handling them, and Ayame was helping him, meanwhile Kurenai was handling Suiren, as Leo started to rip and tear to that of the Flesh Dolls and absorbing them into his Bio mash.
After a while, the dock was clear, and Suiren was knocked out.
Tendo was already gone.
By the time the last Flesh Doll hit the ground—its body half-dissolved into Leo's biomass—the dock was a ruin of broken concrete, scorched metal, and drifting steam.
Leo stood there for a second longer than necessary, breathing slow, forcing the Blacklight back down. The claws melted into human hands, veins fading, skin returning to normal. Whatever biomass he'd absorbed settled, heavy and uncomfortable, like wet cement in his chest.
Ayame lowered her rifle and exhaled.
"…He escaped."
Leo clicked his tongue. "Yeah. Figures."
Kurenai adjusted Suiren so she was lying on her side, checking her breathing. The missing Taimanin was alive—barely—but the control was gone. Whatever device Tendo had been using was destroyed, and without Ingrid backing him up, he'd chosen survival over pride.
Kurenai glanced back at Leo.
"Your Demon form is something else."
Leo gave a small nod. "Thanks."
Then, after a beat—
"…I really didn't want to use it that much."
Ayame walked over, eyes sharp but curious. "You fought like you weren't trained as a Taimanin at all."
Leo shrugged. "I wasn't. Not originally."
Kurenai narrowed her eyes. "That didn't answer the question."
Leo gave her a sideways look, half-smile tired, half-serious.
"Let's just say… when things get bad, I stop fighting like a ninja."
She didn't press further. Not now.
Instead, she looked down at Suiren, expression hardening.
"Tendo's still out there. And Ingrid knowing about the Fuuma Clan—about you—isn't good."
Leo nodded. 'Yeah, that's new.'
Alex's voice echoed in his head.
'She wasn't bluffing. That wasn't random knowledge.'
James followed.
'Which means someone's feeding information upstream. Demon side.'
Leo clenched his fist slightly. 'Great. Multiverse bullshit and espionage.'
Sirens wailed faintly in the distance—cleanup teams, Taimanin support, the usual aftermath.
Ayame tapped her communicator. "Extraction is inbound. We'll hand Suiren over to medical and intel."
Kurenai stood, rolling her shoulders, then looked at Leo again—this time differently. Less like a junior. More like a loaded weapon.
"…You saved all of us back there," she said quietly. "Even when you could've chased Tendo."
Leo scratched the back of his head. "Couldn't leave you surrounded. That'd be a bad end."
She paused. "A… what?"
"Nothing," he said quickly. "Just… bad."
The transport finally arrived, engines humming.
As Leo stepped onto the ramp, he glanced once more at the ruined dock, at the place where the canon was supposed to end neatly.
Instead, Ingrid was free.
Tendo was alive.
And Suiren—someone who should've been broken beyond repair—was breathing.
Leo exhaled slowly.
'Yeah,' he thought. 'The plot's officially off the rails.'
And somewhere deep inside, beneath Taima particles, ninja arts, and demon blood—
The Blacklight stirred.
Hungry.
