It had been a few months since Leo first started developing the Breathing Techniques, and honestly? Things were going way better than anyone expected.
The others picked it up fast—too fast, in Leo's opinion.
Tokiko had taken to Wind Breathing, trying her hardest to copy Leo's movements. Rinko, meanwhile, followed directly in Leo's footsteps and chose Water Breathing. She was determined… maybe a little too determined, considering she once tried to practice in the rain "for authenticity."
But the real shock came from Asagi.
Leo had only explained to her once how Fire Breathing was supposed to work.
And then she just—learned it.
Instantly.
She burned an entire tree, laughed like it was the funniest thing ever, and walked off proud of herself.
Leo, watching from the distance, felt two very conflicting emotions:
1. Terror, because that was a child casually wielding fire like a flamethrower.
2. Emotions he should not be feeling at his age, because prodigy or not, that level of raw talent was frighteningly impressive.
He had expected interest.
He had expected imitation.
But he hadn't expected someone to speedrun an entire technique in minutes.
Asagi wasn't just talented—she was a natural. A literal prodigy.
And for better or worse, Leo had just given her a taste of real elemental power.
The Village Elder did panic.
In fact, the moment Tokiko mentioned "children summoning fire and slicing trees with water," the old man nearly had a stroke. Within minutes, messengers were sent sprinting across the compound to drag Ryuji into the elder's office.
Ryuji arrived mid-coffee, still holding the cup.
The elder slammed both hands on the desk. "Ryuji! Your son—your son—is teaching the children arts that manipulate the elements! They are cutting trees with water! Setting things ablaze! We need answers!"
Ryuji took a long sip. A very long sip.
Then he deadpanned, "You think I know what my son is doing?"
The elder blinked. "…Pardon?"
"News flash," Ryuji continued, pointing at himself with his cup, "I don't. I haven't known for years. The boy wakes up one day talking about 'breathing styles,' the next he's slicing logs in half and calling it training."
The elder leaned forward, voice trembling. "So… what exactly did he name these techniques?"
Ryuji sighed, scratching his head.
"He called them—"
another sip—
"'Elemental Ninja Arts.'"
The elder stared at him in silent horror.
Ryuji shrugged. "Honestly? Sounds cooler than half the stuff I learned growing up."
Meanwhile, in the forest…
Another Oni dissolved into writhing biomass as Leo absorbed it, the Blacklight virus humming through his veins like a second heartbeat. He wiped the excess off his arm, reshaping it back to normal.
'Have you two ever thought of using a long-range weapon?' Leo asked mentally.
James immediately perked up.
'You mean our Whipfist? Because if it's the Whipfist, then—'
'No,' Leo cut him off. 'I mean actual long-range. Like something that lets you shoot from a distance. Projectile-based. You know—ranged weaponry.'
A pause.
Then Alex spoke, voice cold and flat.
'No. Such a thing never came to mind. Our strategy was simple: rush, tear, consume. Efficiency through brutality.'
James added, almost annoyed,
'Yeah, why would we stand far away when we could sprint at Mach whatever and rip someone in half?'
Leo sighed internally.
'Because this world has ninjas. Demons. Mages. People who can snipe you with magic blasts. Maybe—just maybe—having something to shoot back with would be smart?'
Alex hummed, thoughtful now.
'…A weapon that allows us to eliminate targets at a distance while conserving biomass. Interesting. This could increase our lethality.'
James added with sudden excitement,
'Wait… like a gun? Are we finally making guns? Oh my god, we're making guns.'
Leo smirked as he stepped over the corpse.
'Exactly. Welcome to the concept of firearms, boys. I think it's time the Blacklight Hive learned some new tricks.'
Alex's tone sharpened with interest.
'Then let us begin designing. What do you propose first? Primitive firearms? Modern ballistic weapons? Or… something more experimental?'
James:
'Rocket launcher. Please. Just once.'
Leo:
'Baby steps, James. Baby steps.'
Leo thought in his mind. 'How do you guys make Weapons?'
Both James and Alex paused and thought, as Alex wondered for a bit. 'Imagination'.
Leo closed his eyes as he spoke. 'I can't make a Gun yet, too much work, so how about this?'
His right arm got covered with the Black Light Virus as it changed shape and form.
Leo felt the familiar ripple of biomass crawling under his skin, his right arm bubbling and twisting like molten metal reshaping itself. The ground quivered from the pressure spike of Taima Particles reacting with the evolutionary virus.
[Insert image here, Reader's]
James whistled in his head.
'Woah—he's actually doing it. Kid's committing to the idea.'
Alex's voice was calm, analytical.
'He is recalling that image. The one of the ranged biomass weapon. A bow. Efficient. Simple. Versatile. And unlike firearms—it requires no moving parts.'
Leo focused harder, channeling the memory he had seen online years before reincarnating—a monstrous, organic bow used by Evolved beings.
His arm elongated, bones reforming into a curved structure. Black tendrils snapped into place like living metal. Red bio-cables pulsed, threading through the weapon like veins. Spines emerged along the limb, jagged but elegant, humming with restrained killing power.
FWUMP
The transformation completed.
Leo stared at his new biomass bow—spined, twisted, flexible, and alive.
"…Holy crap," he whispered.
James was ecstatic.
'OH LET'S GO! RANGE WEAPON ACHIEVED!'
Alex sounded almost impressed.
'Stabilization is smooth. Shape is consistent with the concept projection. Biomass expenditure is low. This… may be the most practical ranged Form so far.'
Leo held the bow up, testing its weight. It was light—like holding his own arm, because technically… he was.
He pulled back a string made of condensed biomass, and a red tendril of energy crackled along it.
"Okay…" Leo muttered. "Let's test an arrow."
He pulled.
Biomass condensed at the pinch of his fingers—forming a jagged, glowing red projectile.
THWIP
The arrow shot.
BOOM
A tree fifty meters away exploded into splinters.
Leo blinked.
"…I think that was too strong."
James cheered,
'NO SUCH THING AS TOO STRONG!'
Alex corrected immediately,
'That was a charged arrow. The structural instability caused premature detonation. You must adjust the density for non-explosive shots.'
Leo grinned.
"So I just recreated a Prototype bow… in a ninja world."
He paused.
Then fist-pumped the air.
"HELL YES."
Alex spoke in Leo's head. 'Does this mean that you have Unlimited Amo?'
Leo stopped as he thought. "Maybe, with each arrow, my Bio Mass feels a little less".
Alex's tone sharpened, unusually serious for once.
'So not unlimited ammo. Good to know. Every shot costs biomass—meaning every miss is a waste.'
James chimed in immediately with the least helpful input possible.
'Skill issue.'
Leo rolled his eyes. "Yeah, thanks, that really helps, James."
He examined his arm-bow again, feeling the faint pull of fatigue deep inside the virus.
"It's not that much biomass per shot—like… losing a few calories? But the stronger arrows feel like they rip out chunks of me."
Alex responded thoughtfully.
'That aligns with our old mechanics. Large projectiles drain reserves. If you fired too many, you would collapse or revert back to conserve mass.'
Leo sighed. "So basically… I have ammo, but the ammo is me."
James chuckled.
'Congrats, kid. Your body is the quiver.'
Leo pinched the bridge of his nose. "That sounds way worse when you say it out loud."
He tested pulling the bowstring again, this time intentionally focusing on stability, not power. A weaker arrow formed—consuming only a thin strand of biomass.
THWIP
It hit a tree with a soft thunk instead of an explosion.
Leo nodded. "Okay, light arrows don't drain much. Heavy arrows do. So I need to ration my shots."
Alex approved.
'Correct. You now possess long-range capability, but with limitations. Use it wisely.'
James, of course, added:
'Or recklessly. That's also an option.'
Leo ignored him.
He stared down at his living bow, a small smile forming.
"If I train this right… this could be my signature weapon."
He flexed his hand, and the bow melted back into his arm like ink dissolving in water.
Bio-mass restored. Body normalized.
Leo exhaled.
"…Okay. This? This is actually sick."
"No, No, No". A Female voice came
As Leo turned his arm back to normal, he saw it was his mother, and he blinked.
Aoi rushed at Leo as she picked her son up. "NO! You can't unlock that power, not now, not when you're so Young".
Leo blinked as he looked at his Mom. "Mom?".
He was a bit confused. His mom saw him use the black light, but the way she reacted made it sound like she already knew what it was, which she shouldn't.
Aoi looked at him with worried eyes. "No, how did you unlock your Fuuma Demon Power so early?"
Leo spoke in his head. 'What!'.
So did James and Alex. 'What!'
Aoi then rushed back to the Fuuma Clan estate.
Leo's brain stalled.
Fuuma… Demon… Power?
What??
James' voice cracked like a short-circuiting radio.
'Kid. KID. Did she just call us a Fuuma bloodline ability?'
Alex hissed, more offended than confused.
'We are a planet-ending viral apex organism, not a clan kekkei genkai!'
Leo couldn't even respond—Aoi was dragging him like a sack of potatoes.
"A–Aoi, wait—slow down!" Ryuji shouted from behind, sprinting after her with long-suffering dad energy. "At least let me put my shoes on if it's an emergency!"
Aoi ignored him.
She practically kicked the estate door open and rushed inside with Leo clutched against her chest.
Servants froze. Elders spilled their tea. A few guards reached for weapons before realizing it was just Aoi in "full panic mom mode."
Elder Fuuma Genzo nearly fell out of his seat.
"A-Aoi? What in the Nine Realms—?"
Aoi placed Leo on the tatami mat like presenting a fragile bomb.
"He awakened it," she said, voice trembling. "His demonic transformation—already."
Everyone in the room gasped.
Leo pointed at himself.
"…Me?"
Inside his head, Alex groaned.
'Wonderful. This is becoming a diplomatic incident.'
James added dryly:
'At least you're popular now.'
Genzo leaned forward, voice low and grave.
"Child… show us."
Leo panicked.
"Show you WHAT?!"
Aoi put a gentle but firm hand on his shoulder.
"Your Demon Arm, sweetheart. The Fuuma blood manifests through the right arm first. That… monstrous limb. The black one."
Leo's face went pale.
"…Mother, that wasn't a demon arm."
"Then what was it?" Aoi asked.
Leo opened his mouth—
Alex immediately cut in.
'DON'T SAY "bioweapon designed to destabilize civilization," YOU MORON.'
James agreed.
'Yeah, maybe lie. Softly.'
Leo tried to lie.
What came out was not soft.
"…Uh… puberty?"
The room went silent.
Genzo stared.
Ryuji walked in, out of breath, just in time to hear that.
He covered his face with both hands.
Aoi leaned in, voice dangerously calm:
"Leo. Honey. You are seven."
"Seven and a half," Leo corrected automatically.
"Not helping," Alex muttered.
Aoi exhaled deeply—equal parts panic, frustration, and "I love my child but what the hell."
"Leo… please, just show them your arm."
Leo sighed and extended his right hand.
Fwoom.
Blacklight tendrils spiraled, forming the bow again—organic, predatory, pulsing with red veins.
Everyone in the room screamed internally.
Elders recoiled.
Guards reached for weapons.
Aoi covered her mouth in shock.
But Genzo—
Genzo's eyes widened… then slowly softened.
"…It truly is the Fuuma Bloodline," he whispered.
Leo screamed in his head.
'WHAT DO YOU MEAN IT IS?! THIS IS A VIRUS, NOT A GENETIC INHERITANCE?!'
Alex sputtered.
'This clan's genetics must be deranged.'
James concluded:
'Honestly? This explains a lot.'
Genzo nodded to himself.
"Awakened at seven… this child may surpass even the former clan heads."
Aoi hugged Leo tighter.
But this time, she was proud.
Not afraid.
Leo exhaled.
"Oh God… this world is insane…"
