Leo blinked. Once. Twice.
Then he looked down at the small girl waving cheerfully between them.
"…You want us to do what?" Leo asked slowly.
Mizuki Shiranui smiled with the calm confidence of someone about to drop a bomb and walk away from it. She gently adjusted the grip on the girl in her arms.
"Look after my daughter while I'm on this mission."
Asagi's brain took a second longer to process than Leo's.
She crouched slightly to be eye-level with the child. "What's your name?"
The girl straightened proudly and raised her hand like she was in class.
"I am Yukikaze! Happy to meet you, big sister!"
[Insert image of Yukikaze]
Asagi froze.
Leo felt his soul leave his body.
'Oh. Oh no. This is that Yukikaze.'
Mizuki nodded approvingly. "She's very polite."
Leo stared at the kid. Black hair. Pink eyes. Pure energy.
'Yeah, polite. Also canonically a walking disaster flag.'
Asagi looked up at Mizuki, smiling a little too stiffly. "Um… Senpai… how long is this mission?"
Mizuki thought for a moment. "Two days. Maybe three."
Leo choked. "Three days?!"
Mizuki tilted her head. "Is that a problem?"
Leo waved his hands. "No! No problem! Totally fine! I just—"
'—know her entire tragic future and now I'm emotionally invested against my will.'
Asagi elbowed him.
Mizuki leaned down and placed Yukikaze gently on the ground. "Now, Yuki, behave yourself."
Yukikaze saluted. "Yes, Mom!"
Then she immediately turned to Leo, eyes sparkling.
"Are you strong?"
Leo paused. "Define… strong."
She grinned. "Can you shoot lightning?"
Asagi blinked. "Why is that the first question?"
Yukikaze nodded seriously. "Strong people shoot lightning."
Leo sighed. 'Of course.'
Mizuki picked up her gear and stepped back. "I'll leave her with you two. Leo, Asagi—take care of her."
Leo straightened. "I will."
Asagi glanced at him, surprised by the firmness in his voice.
Mizuki hesitated for half a second, then smiled softly. "Good. I trust you."
And with that, she was gone.
Silence fell.
Yukikaze looked between them, hands behind her back.
"So… what are we doing?"
Leo and Asagi exchanged a look.
Asagi crossed her arms. "First rule. You stay where we can see you."
Yukikaze nodded enthusiastically. "Okay!"
Leo added, "Second rule. No running off. No touching weapons. No activating ninja arts without permission."
She tilted her head. "…What's 'permission'?"
Leo winced. "We're doomed."
Asagi sighed and crouched again. "Do you like sweets?"
Yukikaze's eyes lit up like fireworks. "YES."
Leo immediately pointed at Asagi. "You're in charge of snacks."
Asagi smirked. "You're the one with demon powers. You handle emergencies."
Yukikaze looked between them again, grinning wider.
"Wow! I got two babysitters!"
Leo muttered, 'This is not how I imagined changing canon.'
Asagi stood up, placing a hand on Leo's shoulder. "Relax. How hard can it be?"
At that exact moment, Yukikaze's body crackled faintly with electricity.
Both of them froze.
Leo slowly turned his head. "Asagi?"
"Yes?"
"…Did she just spark?"
Yukikaze blinked innocently. "Oops."
Leo exhaled sharply.
'Yep. Canon just walked into my life and brought lightning with it.'
Asagi crossed her arms, chin lifted in confidence.
"How hard can this be? She's seven."
Leo nodded. "And also a Taimanin in training. But yeah—" he waved a hand dismissively, "—it's not like she can just disappear."
They both turned around.
The spot where Yukikaze had been standing was empty.
No small child.
No crackling electricity.
No cheerful presence.
Just… air.
There was a half-second of silence.
Asagi's eye twitched.
Leo's soul left his body for the second time today.
"…Asagi," Leo said very slowly, "don't panic."
Asagi inhaled.
"YUKIKAZEEEEEE?!"
Leo joined her instantly. "YUKIKAZE WHERE ARE YOU?!"
They bolted in opposite directions, instantly abandoning all dignity, stealth, and ninja training.
Asagi skidded across the training ground. "She was right here! She was right here!"
Leo activated Blacklight reflexively, veins flickering as he scanned the area.
'Alex. James. Emergency.'
James responded instantly. 'Kid, what happened?'
'We lost Yukikaze.'
James: '…You lost who?'
Alex's voice came in cold and sharp. 'Explain.'
'Mizuki's daughter. Seven. Electric. Walking canon disaster.'
There was a pause.
Alex: '…How.'
'She blinked.'
James groaned. 'Of course she did.'
Asagi grabbed Leo by the collar. "If anything happens to her, Mizuki will kill us, revive us, and kill us again!"
Leo swallowed. "Yeah. And that's the good ending."
They split up again, searching frantically.
"Yukikaze!" Asagi shouted. "This isn't funny!"
A crack of electricity snapped somewhere nearby.
Both of them froze.
Leo pointed. "That way."
They sprinted toward the sound—and skidded to a stop.
Yukikaze was standing on top of the dojo roof.
On. The. Roof.
She was crouched proudly, hands on her hips, lightning faintly dancing around her fingers like she'd just discovered her superpower.
"Oh! Hi!" she called down happily. "I found a better view!"
Asagi's legs nearly gave out. "How—why—when did you get up there?!"
Yukikaze tilted her head. "I climbed."
Leo stared. "…That's a three-story building."
She nodded. "Uh-huh!"
Asagi slapped a hand over her face. "We lasted thirty seconds."
Leo pinched the bridge of his nose.
'Welcome to babysitting. Difficulty: Nightmare Mode.'
James muttered in his head. 'Kid, you're not surviving three days.'
Alex added flatly. 'Statistically, you're already dead.'
Asagi looked up at Yukikaze, forcing a smile that was one stress fracture away from breaking.
"Yukikaze, sweetie… please come down."
Yukikaze beamed. "Okay!"
She jumped.
Both of them screamed again.
Leo reacted on pure instinct, Blacklight surging as tendrils shot out and caught her midair, lowering her safely to the ground.
She landed, giggling.
"That was fun!"
Asagi dropped to her knees. "I'm going to age ten years."
Leo stared at the girl, deadpan.
"…New rule."
Yukikaze blinked. "Hm?"
"You do not move without telling us."
She smiled brightly. "Okay!"
Beat.
She immediately took one step to the side.
Leo and Asagi snapped their heads toward her.
She froze. "…I told you?"
Leo sighed.
'This is it. This is how the Fuuma bloodline ends.'
Leo looked at her as he spoke. "Ok, whatever you do, Yukikaze, don't move, we are gonna come to get you".
They both blinked, and she was gone again.
Asagi just screamed. "How is she doing that?".
Leo screamed as well. "She is using Thunder Flash and Step without a sword?".
There was a faint CRACK—ZZZT of lightning.
Then nothing.
Asagi stood there, mouth open, eyes wide, soul visibly exiting her body.
"…She did it again."
Leo slowly turned in a circle. "Yukikaze…? Yukikaze this is not a game—"
Another CRACK echoed, this time farther away.
Asagi grabbed Leo by the shoulders. "HOW is a SEVEN-YEAR-OLD using Thunder Flash without a sword?!"
Leo shouted back, equally panicked. "I DON'T KNOW, ASK HER MOTHER—WAIT NO, DON'T, WE'LL DIE."
James' voice came in, stunned.
'Kid… she just used a high-speed displacement technique instinctively.'
Alex followed, colder.
'Correction. She is spamming it.'
Leo clenched his teeth. "She's treating it like a dash button."
Asagi's face went pale. "A… dash… button?"
Another ZZZT—this one above them.
They both slowly looked up.
Yukikaze was now hanging upside down from a tree branch, smiling like she'd discovered the meaning of life.
"Oh! There you are!" she said cheerfully. "You said don't move, so I didn't! I just… went places."
Asagi screamed again. "THAT COUNTS AS MOVING!"
Yukikaze tilted her head. "It does?"
Leo pointed accusingly. "You TELEPORTED!"
She puffed her cheeks. "It's not teleporting! I just go really really fast."
Leo felt his sanity crack.
'She's technically right. That's worse.'
Asagi marched forward, hands on hips, trying very hard to be the responsible adult.
"Yukikaze. You cannot just run around like that."
Yukikaze blinked. "Why?"
Asagi opened her mouth.
Paused.
"…Because it's dangerous?"
Yukikaze smiled brightly. "But I didn't get hurt!"
Leo facepalmed. "That's what makes you dangerous."
Another pause.
Yukikaze suddenly gasped. "Oh! I forgot something!"
Leo and Asagi, in perfect unison: "DON'T—"
ZZZT!
She vanished again.
Silence.
Wind rustled.
Asagi slowly turned to Leo, eyes hollow.
"…I understand now."
Leo nodded grimly. "Why Mizuki always looks tired."
From somewhere in the distance came Yukikaze's voice, faint but excited:
"Big sister! Big brother! I found the kitchen!"
Both of them froze.
Leo whispered, horrified. "…She found food."
Asagi's scream echoed through the village.
"GET BACK HERE BEFORE YOU INVENT A NEW DISASTER—"
James sighed in Leo's head.
'Congratulations, kid. You're babysitting a walking lightning apocalypse.'
Alex added flatly.
'Recommendation: Restrain the child. Gently.'
Leo started sprinting. "Yukikaze! Stop using Thunder Step!"
Her voice replied cheerfully from far away:
"Okay!"
ZZZT—ZZZT—ZZZT
Leo screamed. "SHE SAID OK AND GOT FASTER!"
Asagi chased after him. "THIS IS A NIGHTMARE!"
Somewhere, Mizuki sneezed—and had no idea how close her daughter was to rewriting the laws of ninja childcare.
A few minutes later.
The trio was in Leo's house, as Asagi put Yukikaze on the couch, and they both sighed and looked at each other like tired Parents.
Leo kneeled to meet Yukikaze Eye to eye. "Ok, new rule, no using Thunder Flash and Step".
Yukikaze tilted her head, big blue eyes blinking innocently.
"…Why?"
Leo's soul left his body for half a second.
Asagi sat down hard beside him and immediately backed him up. "Because it's dangerous, Yukikaze."
Yukikaze frowned, genuinely thinking about it. "But Mama uses it all the time."
Asagi froze.
Leo froze.
They very slowly turned to look at each other.
Leo whispered, "She pulled the parental precedent card."
Asagi pinched the bridge of her nose. "Of course she did…"
Leo took a deep breath, resetting himself like a man defusing a bomb. He looked back at Yukikaze, voice calm but firm.
"Okay. New explanation. Your mom is a fully trained adult Taimanin."
Yukikaze nodded seriously.
"And you," Leo continued, pointing gently, "are seven."
Yukikaze gasped. "I am!"
Asagi leaned in. "Seven-year-old Taimanin are not allowed to use advanced movement techniques without supervision."
Yukikaze blinked. "…What's su-per-vi-shun?"
Leo answered immediately. "It means Asagi or I are watching you."
Yukikaze's eyes lit up. "Oh! Then can I use it if you watch?"
Leo opened his mouth.
Asagi slapped a hand over it. "No."
Yukikaze pouted. "That's not fair…"
Leo felt the guilt stab him in the chest. He softened his tone. "Hey, it's not a punishment. We just don't want you getting hurt, okay?"
She looked down at her hands. "…I don't like being slow."
That hit harder than expected.
Asagi's expression softened instantly. She crouched down so they were eye level too. "You don't have to be fast all the time."
Yukikaze looked up. "But if I'm not fast, I'll be useless."
Leo's smile vanished.
'…That's too mature a thought for a kid.'
He placed a hand gently on her head. "Yukikaze, listen to me. Being strong doesn't mean always going full speed."
She hesitated. "…It doesn't?"
"Nope," Leo said. "It means knowing when to go fast."
Asagi smiled warmly. "And today, your job isn't fighting or training."
Yukikaze tilted her head. "Then what's my job?"
Leo grinned. "Surviving babysitting."
Asagi snorted before she could stop herself.
Yukikaze giggled. "That sounds easy!"
Leo and Asagi exchanged a look.
They both knew—
That was the biggest lie told in that house all day.
Asagi stood up and crossed her arms. "So. Final rule."
Yukikaze straightened like a soldier. "Yes!"
Asagi spoke clearly. "No Thunder Flash. No Thunder Step."
Leo added, "No disappearing."
Yukikaze nodded seriously. "…Okay."
They waited.
Three seconds passed.
Five.
Ten.
Leo relaxed. "See? That wasn't so hard."
Yukikaze smiled sweetly.
"…Can I use lightning for snacks?"
Asagi screamed into a pillow.
Meanwhile in a different place.
Suiren tried to grab one of her swords, but almost like electricity came out of her hand as she dropped.
Ryuji raised his eyes as he spoke. "What's wrong?".
Suiren looked at the male Taimanin as she spoke. "You didn't see the lighting?".
Ryuji raised an eyebrow. "Lightning? I only saw you grab the sword and drop it".
Suiren stared at her hand, flexing her fingers slowly.
"…It shocked me," she said quietly. "Like lightning crawled out of my palm."
Ryuji's expression didn't change much, but his eyes sharpened. "And you're sure it wasn't static? Residual chakra misfire?"
Suiren shook her head. "No. I've had misfires before. This was… responsive. Like something answered my intent."
She reached again, more cautiously, toward the sword.
The moment her fingers brushed the hilt—
Crack.
A thin arc of pale-blue lightning snapped from her hand. She gasped and recoiled, clutching her wrist.
Ryuji still didn't see it. "There was nothing there".
One of the other Taimain brought a Tablet, as she saw the clip, and it was the same thing with Ryuji; she grabbed it and then dropped it as lightning struck her.
Ryuji looked at her as he spoke. "Maybe, it's a mental block, not mind control, not blocked by Nomand, but your own mind's Guilt".
Suiren's breathing slowed, but her eyes stayed fixed on her hand, as if it were something foreign.
"…Guilt?" she repeated.
Ryuji nodded, folding his arms. "It happens. Especially to Taimanin who were captured but not fully broken. Your mind remembers something your body doesn't want to accept yet."
She clenched her fist. This time, nothing sparked—but the faint numbness lingered.
"I don't feel guilty," Suiren said firmly. "I didn't choose what they did to me."
"I know," Ryuji replied calmly. "But knowing something and believing it are different things."
The other Taimanin scrolled through the tablet again, replaying the footage frame by frame. There was no lightning. No chakra spike. No abnormal energy reading.
Just Suiren reaching.
And recoiling.
"That's the strange part," the operator said. "Sensors didn't pick up any elemental discharge. If it were real lightning, even low-level, we'd see something."
Suiren swallowed. "But I felt it."
Ryuji stepped closer. "Pain doesn't need to be real to hurt."
She looked up at him sharply. "So you're saying I imagined it?"
"I'm saying," Ryuji answered evenly, "that your mind may be protecting you. Or punishing you. Hard to tell which, sometimes."
Suiren looked back down at the sword.
"…When I try to grab it," she said slowly, "I feel like I shouldn't be allowed to."
Ryuji's gaze softened, just a fraction.
"That," he said, "sounds a lot like guilt."
Silence hung in the lab.
Suiren closed her eyes.
Images flickered behind them—blurred, fragmented. Orders she didn't remember accepting. Battles she fought on instinct alone. Kurenai's face, shocked… disappointed… hurt.
Her hand trembled.
"…If it's my mind," she asked quietly, "how do I make it stop?"
Ryuji didn't answer immediately.
Instead, he reached out, took the sword by the hilt himself, and held it out toward her—careful, non-threatening.
"You don't force it," he said. "You don't fight it."
She opened her eyes and looked at the blade.
"You remind yourself," Ryuji continued, "that you're here now. That you're not their weapon anymore."
Suiren hesitated… then slowly reached out again.
This time—
No lightning.
No shock.
Her fingers closed around the hilt.
She froze, waiting for pain.
It didn't come.
Her grip tightened.
"…It's gone," she whispered.
Ryuji nodded. "For now."
She looked up at him, confusion mixing with something fragile. "For now?"
He met her gaze evenly. "Guilt doesn't vanish all at once. It waits. Especially when something—or someone—triggers it."
Suiren's thoughts immediately went to Kurenai.
"…Then what happens when it comes back?"
Ryuji turned away, already walking toward the exit. "Then we deal with it."
He paused at the door.
"And Suiren?"
She looked up.
"If you ever see lightning again," he said, "tell me first. Not the elders."
Her eyes widened slightly.
"…Why?"
Ryuji's expression darkened, just a bit.
"Because if you can see it," he said, "but the world can't…"
He opened the door.
"…Then it might not be guilt anymore."
Back with Leo, after a few hours, Baby Seating the Gremlin, both Asagi and Leo were in their patios
Asagi finally snapped and
"Fu-"
Leo holds Asagi's mouth as both 15-year-olds look at 7-year-old Yukikaze. "You can't curse, we are babysitting a Child".
Asagi, seeing this, just screamed out the first thing that came to her mind. "CUPCAKES ON A STICK!"
Leo just blinked and looked at her. "Yeah, that works".
Yukikaze then copied what she heard. "Cupcakes on a Stick".
Asagi just blinked. "She's gonna use that for everything instead of herher".
Leo just sighed. "Probably".
Over the 3 days, Leo and Asagi invented new things in front of Yukikaze such not to swear front of the Child
Rainbow Flaffers (This is bullshit)
Ribbon Book Let (Go to hell)
Jelly-filled donuts (You mother fucker)
Suger Donuts (Mother Fucker)
Leo slumped back against the patio railing, staring up at the sky like it had personally wronged him.
"…We have accidentally created a new language," he said.
Asagi, wrapped in a blanket and clutching a cup of tea like a lifeline, nodded solemnly. "A cursed one."
Yukikaze sat cross-legged on the floor between them, humming happily as she stacked rocks into what was clearly some kind of chakra formation.
"Rainbow flaffers," Yukikaze said proudly.
Asagi twitched.
Leo raised a finger immediately. "Nope. No context. We don't ask. We don't learn."
Yukikaze tilted her head. "Why?"
Asagi opened her mouth.
Leo instantly clapped a hand over it again.
Asagi muffled, eyes burning with rage.
Leo sighed. "Because some words are… forbidden ninja arts."
Yukikaze's eyes sparkled. "Like secret techniques?"
Asagi slowly removed Leo's hand from her mouth, forcing herself to breathe.
"…Yes," she said through clenched teeth. "Exactly like that."
Yukikaze gasped. "I wanna learn forbidden words!"
Leo panicked internally.
'Abort. Abort. New rule needed now.'
He dropped to one knee in front of her, dead serious. "Yukikaze. Listen carefully. Forbidden words are very dangerous."
"How dangerous?" she asked.
Asagi leaned in, whispering dramatically. "If you say them… lightning might strike."
Yukikaze's eyes went wide. "Really?!"
Leo shot Asagi a look.
'You are not allowed to mention lightning.'
"…Uh," Leo recovered quickly, "emotional lightning."
Yukikaze nodded like this made perfect sense. "Ohhh."
She stood up, struck a dramatic pose, and declared:
"I will protect the village from… Sugar Donuts!"
Asagi collapsed forward onto the table.
Leo pinched the bridge of his nose. "…We are doomed."
---
Later that night
Yukikaze was finally asleep, curled up with a blanket and a stuffed animal she'd named Mr. Thunder (Leo refused to ask why).
Asagi and Leo sat side by side on the patio, utterly exhausted.
"…I miss swearing," Asagi said quietly.
Leo nodded. "Same. I never realized how much emotional regulation it provided."
They sat in silence for a moment.
Then Asagi smirked. "Rainbow flaffers."
Leo snorted before he could stop himself.
They both froze.
Slowly, they turned their heads toward the sleeping child.
Yukikaze rolled over in her sleep.
"…Cupcakes… on a stick…"
Asagi covered her face. "We've ruined her."
Leo leaned back, staring at the stars. "Nah. She's a prodigy. She'll grow up fine."
A beat.
"…Possibly with a very strange vocabulary."
Asagi laughed softly, resting her head against his shoulder. "Thanks for helping, Leo."
He glanced at her, then back at the sky. "Anytime."
Inside, the gremlin smiled in her sleep.
And somewhere in the future—
The ninja world would come to fear two things:
⚡ Thunder Flash
🍰 And cupcakes on a stic
