Kaminari is completely dry. Never in his life has he discharged this much electricity, and he's certain over half of his neural pathways are fried by this point. He'd crossed the threshold of his "yay" mode over an hour ago, but he was clinging desperately to what was left of his mind, fighting for control of his body. He couldn't afford to dissolve into unconsciousness-not now.
Out of the corner of his eye, he spots Yao-momo fending off a Nomu with a spear, her movements sluggish as red drips down the side of her face. Ice and explosions in the distance let him know Todoroki and Bakugo are still fighting for their life, and give him the resolve to keep going. He grits his teeth and tries to force his weakened body to shoot off more sparks.
It had been a surprise attack (though at this point, he's not even sure they can be counted as surprises), except instead of the regular bottom-tier villains, the League had sent them a couple dozen mini Nomus. They were much weaker and smaller compared to the one All Might had fended off at USJ, yet Class 1-A was skating on the brink of defeat, holding out for the arrival of pro heroes.
His shoes squelch against the exposed guts of a Nomu, and a sudden lump in the floor sends him crashing onto the ground. Muttering a curse under his breath, he rolls himself over and is struggling to his knees when he spots it.
Oh, God no. Never in his life has he ever stepped inside a church, but Kaminari can't deny that he's sending a couple hundred prayers skyward as he crawls closer. He rubs his fingers around the bloody jack sticking out from underneath the monster, and slowly, cautiously, pushes the creature over. He hiccups, and then nearly vomits as he stares, transfixed, at his unmoving classmate coated in blood.
He tries to rub it off of her face but only succeeds in drowning his fingers in the sticky substance. Kaminari tries to shake the blood off but it only ends up on his face now, so he gives up and runs his thumbs along her cheeks-trying his best to at least move some of it aside if he can't get it off.
He knows what he'll find, but he still claws through the blood to uncover her eyes. Black pupils stare lifelessly back at him, and he doubles over now, unable to stop the tears from mingling with her blood. He can't even feel his arms, but he feels his body dutifully following Thirteen's Rescue 101, running along the side of her neck to try and find some sort of pulse.
In the silence on the battlefield, he can't hear her heartbeat and he feels the effects of overusing his Quirk finally catching up to his body. His vision slowly begins to shrink to a tiny window of color with her face at the center, and he feels himself falling ever-so-slowly by her side.
Wait. An idea sparks in whatever remains of his brain, and he fights to retain consciousness. His vision's flickering in and out now, black and purples spots dancing across his eyes as he keeps his gaze trained on her unmoving lips.
His body's a far cry from electric-proof and the charred feeling in his lungs give him the impression that more than half of his organs are burnt at this point. He feels completely hollowed out, not a spark left inside his cells, so if he goes through with this he knows it'll destroy whatever's left of him.
Not that he cares. He brushes sticky strands out of her face and watches as tears blur his vision. There are worse ways to go, right?
And it was worth it. A dumbass like him for someone smart and quick-witted and powerful like her. He knows she'll probably save ten times the amount of people that he'd be able to, so he tries to write it off as a more-than-fair trade and not think twice about it.
It's just that there's a million things he'd wanted to do with her. He'd been working on a piece on his guitar for her, a-and there was the school festival next month and the dance in the fall of next year and-
He stops himself before he dissolves completely and draws a shaky breath in. Time is not on either of their sides, so before he passes out, he leans in close and scrapes his entire body for the remnants of his sparks. He lets the electricity light his entire body on fire as his lips meet hers and he discharges the rest of his life to kickstart her heart.
