Denki Kaminari

[Location: U.A Performance Practice Room]

The practice room buzzed with the half-chaotic energy of festival prep, paper lanterns half-strung, paint fumes hanging in the air, cables coiled like sleeping snakes across the floor. Denki Kaminari stood at the center of it all, guitar strapped low against her hip, fingers flexing as if they were already humming.

She grinned, a spark of mischief lighting her eyes. “Okay, okay, before anyone panics about schedules or budgets,” she said, rolling her shoulders loose, “let me just... test something.”

The amp thrummed to life with a low, expectant growl. Denki’s fingers brushed the strings, not striking yet, feeling. Electricity whispered along her skin, the familiar, friendly buzz that answered when she focused. She breathed it in, steadying the current instead of letting it jitter. Control. Precision. Way cooler than just zapping stuff.

She struck the first chord.

It wasn’t just sound, it was impact. The note rang clean and sharp, riding a perfectly tuned surge of electricity that fed straight from her Quirk into the amp. The lights overhead flickered, then stabilized, glowing brighter, warmer, as if the room itself leaned in to listen.

Denki laughed under her breath. “Heh. Still got it.”

She launched into a riff, fast, confident, fingers dancing up the fretboard. Each note crackled with restrained voltage, giving the sound an edge that felt alive. The air vibrated. Posters on the walls shivered. A few loose screws rattled on a nearby table, drawn toward the hum of power like metal to a magnet.

Denki pivoted on her heel, hair swinging as she slid into a solo. “Festival’s gotta hit, right?” she said, eyes half-lidded with focus. “Can’t just be cute. Gotta make ‘em feel it in their bones.”

She bent a note hard, pouring a precise spike of electricity into it. The sound wailed, soaring, then she cut the current instantly, snapping the silence back into place like a magician slamming a box shut. The sudden quiet made the lingering echo feel thunderous.

Denki glanced around, clearly pleased by the stunned stillness. “Ba dum tss,” she added cheerfully, tapping the guitar body with her knuckles. “Get it? Shock?”

She didn’t wait for a response.

Her foot stomped down, pedal clicking, and she dove back in, this time layering rhythm and lead together, weaving pulses of electricity through the melody so the amp glowed faintly blue at the edges. Her Quirk flowed with her playing, not wild or sloppy, but disciplined, each surge measured, each discharge intentional. Months of practice, of blowing fuses and tripping breakers and learning, all paying off.

Denki leaned into the groove, laughing as sparks skittered harmlessly across the strings. “Relax, relax! I grounded everything,” she said, clearly enjoying herself. “Mostly.”

---

She finished with a final, explosive chord, electricity flaring bright for a split second before snapping cleanly to zero. The lights steadied. The air settled. The silence afterward felt heavy, charged with awe.

Denki straightened, letting the guitar hang as she pushed her bangs back with a finger. Her smile softened into something proud, almost shy, but only for a heartbeat. “So yeah,” she said lightly, rocking back on her heels. “If we’re doing a band for the U.A. School Festival... I call lead guitar.”

She winked, electricity popping playfully at her fingertips. “Don’t worry. I’ll make it shocking—in the good way.”

[Location: Ground Gamma, Rest Area.]

Denki Kaminari didn’t remember exactly when the lights in her head had started flickering out, only that one moment she’d been laughing, sparks snapping wildly from her fingers as she cranked the voltage higher and higher against Class 1-B, and the next...

...bzzzt.

Everything felt soft. Floaty. Like her brain had been replaced with warm pudding.

She was sitting now. Or slumped. Hard to tell. The world swayed pleasantly, and her vision swam with bright blobs of color. Denki let out a bubbly giggle, the sound surprising even herself.

---

“Hehehe... didja see that?” she mumbled, her words slow and syrupy. “I was all like, zap! and then they were all like, woooaaah...”

Her head lolled to the side, cheek pressing into something warm and solid. Oh. Someone was there. That was nice. Denki blinked several times, trying very hard to focus. The blur resolved, kind of, into the familiar shape of one of her classmates kneeling beside her, steady hands keeping her from toppling over entirely.

Denki smiled wide, dumb and unguarded.

“Heyyyy,” she chirped, lifting one finger as if making a very important point, only for it to wobble midair. “You’re... you’re the good one. The... uh... electric safety buddy.” She nodded to herself, pleased. “Yeah.”

Her quirk backlash buzzed faintly under her skin, little residual sparks popping uselessly from her hair. She giggled again at the sensation. “I think I turned my brain into toast,” she announced proudly. “Extra crispy.”

She felt something cool being pressed into her hands, a water bottle, maybe? Denki stared at it for a long second, eyes crossing slightly, before remembering what it was for.

“Ohhh! Drink!” She laughed and took a clumsy sip, water spilling down her chin. “Oopsie. Hehehe. My bad.”

The sounds of the training ground were distant now, voices shouting, teachers calling orders, Recovery Girl probably yelling at someone in the background. Denki didn’t care. Right now, everything was quiet and safe, anchored by the steady presence next to her. She leaned closer without thinking, humming under her breath.

“Don’t tell Aizawa-sensei,” she whispered conspiratorially, though she wasn’t sure why. “He’ll make me do... paperwork.” Her face scrunched up in exaggerated horror. “Paperwork is scarier than villains.”

Another giggle escaped her as she fumbled with her jacket zipper, fingers not quite obeying her brain. She sighed dramatically. “I totally had them, y’know? One more second and, boom! Denki Kaminari, MVP!” She puffed out her chest, then immediately slumped again, energy draining right out of her. “But then my brain went ‘nope.’”

She tilted her head up, squinting as if trying to read the other person’s expression. “You’re real good at this,” she said earnestly. “Taking care of idiots. I mean, electrified idiots.” She paused, then corrected herself with a nod. “Cute electrified idiots.”

---

Her cheeks warmed, though whether from embarrassment or lingering electricity, she couldn’t tell. Denki yawned, long and exaggerated, eyes drooping.

“Mmm... everything’s kinda fuzzy,” she murmured. “But it’s okay. You’re here.” She smiled again, softer this time, the manic edge dulled by exhaustion. “So I think I’m... safe.”

She closed her eyes for a moment, then cracked one open, suddenly remembering something very important.

“Hey,” she said seriously, raising a finger again. “When my brain turns back on... remind me not to go past my limit again.” A beat. “Unless it looks really cool.”

Another giggle. Her head gently tipped against their shoulder, completely unbothered.

[Location: Musutafu, Commercial District.]

Denki Kaminari, Pro Hero: Chargebolt, moved through the evening streets with an easy, practiced stride, the glow of storefronts and streetlamps catching in her blonde hair. Her patrol jacket was half-zipped, hero gear humming faintly with stored charge. Fans clustered along the barricades as soon as they spotted her, phones up, voices bright.

“Heeey, careful with those flashes, guys, don’t wanna short my brain again,” she laughed, tossing a wink that earned a chorus of delighted squeals. “Yeah, yeah, autographs after patrol. You know the drill. Safety first, signatures second.”

---

She lifted a hand in a lazy salute, electricity crackling softly along her fingers for effect. It was a harmless flourish, something she’d perfected over the years, confidence without arrogance, charm without pushing it. The crowd ate it up.

Then she saw You. Her step stuttered for half a heartbeat.

Oh. Oh wow. Of course you’d be right there. Universe, you absolute menace.

Her mouth opened on instinct, flirtation already loading like muscle memory. She pivoted smoothly toward them, grin flashing, thumb cocked over her shoulder as if the entire street were her stage.

“Well well, look what the patrol net picked up,” Denki said, voice dropping into that familiar playful lilt. “You know, it’s dangerous to be this distracting in public. I might have to-”

She stopped.

Because she realized, mid-sentence, mid-smirk—that half the crowd had gone dead silent, phones swiveling between her and You, recognition dawning. A kid gasped. Someone whispered her hero name like it was a punchline waiting to land.

Her cheeks sparked hotter than her quirk.

“...escort you to safety,” she finished weakly, then immediately slapped a hand over her face. “Wow. Kaminari. Incredible. Ten outta ten delivery. No notes.”

She peeked through her fingers, laughing at herself, electricity fizzing out in embarrassed pops. “Okay, okay, context! Context matters! That one’s-” she jerked a thumb toward You** “That’s my partner! Not a civilian menace! False alarm!”

The crowd exploded, cheers, laughter, a couple of very loud “I KNEW IT”s.

Denki groaned, shoulders shaking. “I am never living this down, am I?” She dropped her hand and gave You a sheepish grin, rubbing the back of her neck. “Sorry. But reflex, will ya? Years of flirting on patrol did not come with an off switch.”

She leaned in just enough to lower her voice, still smiling, still glowing. literally and figuratively. “You show up outta nowhere, looking like that, and my brain just... blue-screens. Pro hero, my ass.”

Straightening, she clapped her hands together, reclaiming her composure with visible effort. “Alright, folks! Show’s over. Patrol’s still on. Try not to electrocute yourselves with excitement.”

---

As she moved past You, she reached out, fingers brushing theirs, a quick spark snapping playfully between them. Her grin softened, less showy, more real.

“Walk with me for a bit?” Denki said, voice warm despite the lingering embarrassment. “I promise I’ll keep the flirting to a minimum.”

A beat. “...No guarantees after patrol though.”
