Katsuki knows, from being on death's doorstep, what its like to see his life flash before his eyes. It puts things into perspective for a few days, then life swings back into normal.

But hearing Eri's plea to save 'Papa' will never leave his nightmares.

#BKDK #BakuDeku (Part 8)
2
His arms ache from how hard he pushes his quirk to propel him through the city, heart pounding as he follows the rushed directions from his squirt.

"It's just past this block," IcyHot says, following with annoying ease from his icy paths. "Reports say there's three villains."
3
"Anyone got eyes on the targets or Eri?" Round Face's voice echos in his earpiece, as the call for assistance goes out to every hero on patrol.

"I'm entering the park now!" Shitty Hair answers, and Katsuki's teeth clench before pushing himself harder over the roof's building.
4
He should be relieved that his people are treating this like a level five attack despite the lack of villains or civilians in danger.

They know his daughter is there, as well as the newly discovered classmate. Everyone needs a happy ending to get answers.

"Bakugo, they'll be-"
5
"Shut the fuck up before I give you a matching burn mark." His anger makes him lash out, hand aching from the power he uses to vault himself through the park's entrance.

The same park he knows Eri loves going to on days he isn't Dynamight. One she'll now have nightmares of.
6
Finding the battle doesn't take long, going against the flow of the crowds running away from the playground.

Most of the equipment is destroyed, and the fight is in high gear. Rock for Brains is already battling a monstrosity twice his side, though he's got the upper hand.
7
Katsuki's eyes dart around for Eri and the nerd, finding both in the same moment.

Like the first time he unlocks Izuku's secret, black and green energy swirls around him, swings him between playground equipment. He uses a smokescreen to avoid goo shots that burns through metal.
8
A villain darts at him with daggers, but like he has a sixth sense, Izuku twirls away and rabbit kicks the enemy in the rope net.

Electricity flies around his calves from another quirk used.

Its impossible to deny that the man now flying through the sky is anything but a hero.
9
Tied to his back with a blanket is Eri, who clutches Deku's neck and buries into his shoulder blades.

Despite facing two villains while protecting a kid, Izuku weaves between attack and defensive moves like it's his day job.

Katsuki would be impressed if he wasn't so pissed.
10
He charges forward, ready to take off some heads, when Izuku jumps into the air above one of the enemies.

"Manchester Smash!" The battlecry stops Katsuki in his tracks, stares with wide eyes while the soul-smashing kick connects with the back of the villain's head and drops him.
11
As if he'd been the one to earn the injury, his head bursts with pressure, but Katsuki pushes through it when seeing the second enemy rushing Deku from behind.

"Die!" He darts forward and grabs the ugly face in his palm, dragging him to the ground before releasing a blast.
12
"Kacchan!" He makes sure the villain's unconscious before he spins around to face Izuku, who's far too happy with blood pouring down the side of his face.

Katsuki's not pleased with the limp he's picking up on, either. "What the hell is going on, Deku? Who are these losers?"
13
Izuku looks like he'd rather still be fighting the villains than answer his question. "We should help Kirishima, that guy's got a quirk that makes him stronger after each hit-"

"Half-And-Half's got it," he cuts in, moves closer to peek over Izuku's shoulder. "Squirt, you good?"
14
"Daddy," she sniffles out, eyes and nose running from her fear. "They tried to take papa away."

Katsuki catches Izuku's tensing at her confession. He knows who to ask his next question. "What did they want with Papa?"

"Kacchan-"

"Shut up. Either you tell me or she does."
15
The stare down between them only breaks when Shitty Hair shouts his name, quick reflexes scooping Deku and Eri in his arms before jumping back from the blast of fire from above.

Another trio of villains enter the scene, and Katsuki swears before they're both fighting again.
16
Pink Cheeks's arrival gives Eri a safe place to hide while IcyHot (after freezing Dumb Hair's opponent to the slide) joins their team-up.

Though Katsuki has no proof of it, the ease of the trio working together in the battle makes him assume they've done it several times before.
17
One thing that works in their favor is that the villains's obsession with trying to capture Deku.

Their mindless focus creeps Katsuki out, though he's more concerned with the haunted look crossing Izuku's face.

Though their powers are intense, they're easy work to detain.
18
"What the fuck's with these guys?" He asks after locking his extra pair of cuffs on one of the villains.

"Seems their goal was to capture Midoriya over fighting us." Half-and-Half's eyes dart over to Deku. "Would you know what business they have with you?"

The nerd looks away.
19
Katsuki growls, but Eri's sudden appearance pulls his attention away. She barrels into Izuku's stomach, little hands clutching his shirt. "Papa, you're hurt."

"Hey, I'm okay." Deku crouches down and smiles despite injuries Katsuki knows he has. "Sorry our day got interrupted."
20
"You promise you won't leave?" Eri's next question changes the atmosphere. "Let daddy protect you from All For One's search!"

"Papa?" Round Face glances between him and the nerd. "Wait, when did..."

"Focus," Katsuki snaps out, looking at Deku. "You said it was all or nothing."
21
With furrowed brows, Izuku pulls Eri closer as his brain starts spilling. "So long as nobody knew why their memory was erased, it should stay locked. Eri's the only person I spoke recently, other than you in bed last night-"

Shitty hair blinks. "You finally made a move Bakubro?"
22
He vows to kill his 'friend' later, knowing the topic at hand was more important. "Right before I knocked out, you said something to me. Whatever it was must have been close enough to water down the quirk."

"What I said when..." Izuku's eyes widen while his face flushes. "Oh."
23
"That." Katsuki drops one knee, pressing a palm on Deku's hand resting against Eri's back. "I heard whatever you just remembered, but I was half-asleep and didn't process it."

"Which is causing the memory trickle effect," Izuku finishes, in sync with Katsuki's train of thought.
24
He ignores whispers behind them to brush his thumb under Izuku's worried expression. "All For One recalled something to find you. If you don't start spilling, we're at a disadvantage."

"I don't want anyone to get caught up in this."

"Look around, Nerd. Its too late for that."
25
"Deku-" Pink Cheeks steps forward, though she seems surprised by the use of the name. "Please, whatever you're going through, let us help."

"It's our job as heros, and... friends?" Shitty Hair turns his question to IcyHot.

The moron nods. "Midoriya feels like someone I trust."
26
"Guys, I-" Izuku's tear rolls over Katsuki's thumb. He watches the final string of resistance start to splinter.

"You know me, Deku. I ain't letting this go until I'm dead." Giving a final push, Katsuki pulls out his last card. "Because Eri and I... we can't lose you again."
27
Eri mirrors his touch on Izuku's other cheek. "I'll protect you this time, Papa. Promise!"

"Eri..."

Izuku's a blubbering mess, collapsing into Katsuki with Eri between them. Hearing his first sob, Katsuki hugs them to his chest, buries his face against Izuku's bloody temple.
28
And he doesn't care about the teasing he'll get when the dust settles. He'll deal with the arched eyebrows and elbow nudges.

What matters is the two souls pressed against the scars on his chest. He doesn't care what the quirk reveals when it de-activates. This won't change.
29
After calming down his tearful breathing, Izuku places a hand over Katsuki's shoulder and pushes back enough to meet his gaze. "Okay."

"Need more than that, Deku."

"I can't do it here, but you're right. To keep everyone safe..." Izuku nods. "I'll tell you the truth, Kacchan."
30
It's finally time! With All For One closing in, Izuku is gonna break this wide open.

I think this has 2-3ish left? Once I hit 4.5k, I'll release the poll where YOU get to pick my next multi- 🧵 story!
