Chapter Text
“Ne, ne, Tsumi-chan!” Emiko calls, running as quick as she possibly can. Katsumi continues to walk quicker. The bell signaling the end of the school day had rung just a moment ago and she basically high-tailed it out of the classroom, yet Emiko was still following after her like a little puppy. “Do you remember the homework?”
Katsumi stops to glance at her, a smile–one that she hopes looks genuine–plastered on her face “No, but why don’t you go back and ask Morimiya-sensei yourself?” She says before continuing to walk forward. Emiko only follows with a confused look, hair floating after her. Katsumi slowly starts to give up losing her and starts slowing her steps. “What do you want?”
Emiko clasps her hands in front of her and leans forward to look at her. “A training session!” She says happily.
“You don’t look like much of a fighter.” Katsumi comments, raising an eyebrow at her. She didn’t mean to be rude–although it most certainly seemed purposeful, coming from her–Emiko didn’t seem very skilled in combat. Hell, just the other day she saw Emiko chasing after a butterfly before she slammed into one of the security walls and got herself trapped in a net.
Of course, as the daughter of the number one(ish) hero and the number five hero, she knew about and knew basic knowledge about Deku, Emiko’s father. He’d been more cowardly when he was a kid but grew into his power. She wouldn’t be surprised if she was the same. “Especially considering who your father is.”
“My… father?” Emiko asks. “Oh, Deku! How does he affect me?”
“De–what?” Katsumi shakes her head before turning to Emiko. “Nevermind. What do you need help with, exactly?”
Emiko pauses before a black, shadowy smoke releases from her hand and wraps around Katsumi’s arm. “What the–” Katsumi tugs her arm away only for the smoke to tighten around her arm even tighter, like a blood pressure machine. She throws her arm over her head in a feeble attempt to get Emiko’s weird black shadow away from her, only for it to follow her and get progressively tighter. “Fuck–what are you doing right now?”
Emiko slaps her hand and the shadow goes away, retreating back into Emiko as the blood being held back in Katsumi's arm rushes back, making her sigh. As her arm slowly begins to return to its normal color, she starts to pull on her fingers. “That’s what I need help on.” She says, a quiet frown sitting on her face. “My Quirk… I can’t control it a lot. My dad says that my Quirk is powerful, but hard to control. He says he passed down one of One For All’s Quirks, but it’s tricky to direct where Blackwhip forces its attention.”
One For All.
Most of the details weren’t known to the general public, but the Bakugo family had a large record about it in their study. There were nine users, the ninth being the present wielder, Izuku Midoriya. The previous users couldn’t use the other Quirks, which was strange when Izuku possessed all of their Quirks.
Katsumi crosses her arms. Why would Emiko only inherit one Quirk from him? And it’s also around the time when he was supposed to pass down One For All. So then does she need help with controlling it so she can inherit more? Maybe she has to build up her–
“Wait.” Katsumi forces herself not to frown. “So you want me to just act like a punching bag while you practice with your Quirk?” She asks snarkily.
Emiko shakes her head with vigor, enough for her hair to start flying into her face. “No! I want you to help me control it!” She pumps her fists in front of her, determination on her face. “I saw you during the Entrance Exam and you were really good with controlling your explosions! You have that Air Explosion Quirk, right?” She walks closer to Katsumi, causing the latter to take a step back. “C’mon, you have to help me!”
Katsumi turns away and clicks her tongue. It had taken a lot of work to control her explosions.
Not to mention that her father acted like a tyrant the whole time.
But Blackwhip.
From Emiko’s vague and not very specific description, she knew a lot. Blackwhip was originally the fifth holder’s Quirk. It was reckless and hard to use, much like Emiko’s. It once came out randomly during a training session with Izuku, but he got it under control after Ochako swooped in to help him.
“My father said that I have to learn how to control and learn how to be precise with it.” Emiko says, stretching her hand out in front of her. “The only reason I managed to pass the entrance exam was because the robots were big and it wasn’t that hard to restrain them.” Her face drops and she looks away. “I just need your help with being precise. If you don’t want to–”
Katsumi slaps a hand over her mouth, quickly interrupting her. The grin that she flashes is close to that of a predatory one. “Nope. I’m doing this. And if we’re doing this, we’re going all the way. I’m no sensei, but I’ll do my damned best to help you.” She warns.
Emiko smiles. Her hands shoot out to grab Katsumi into a hug before the latter quickly moves to the side, swiveling her hip so she easily avoids Emiko. “Rule one, no hugging.” Emiko shakes her head up and down rapidly. “Rule number two, practice starts right after school.”
She jumps up and turns around to run down the hallway before she stops herself short. “Wait, but what about homework?” Emiko asks.
Katsumi crosses her arms. She swears she was going to kill her before their arrangement even started. “You’ll have time to do homework.” She says.
“No, I mean about the homework! Should I ask Morimiya-sensei about it or do you know what pages we have to read?” She unzips her bag and brings out a notebook, little sticky tabs poking out from the side, the cover decorated with stickers. “I know the math homework, but what about the English reading?”
Katsumi sighs before pointing back to the classroom and saying, “Go ask Morimiya-sensei about the homework then meet me in one of the training rooms in Gamma Gym. I'll reserve the first room. Wear something comfortable.”
Emiko’s head drops to her side and her other hand raises to her head in a salute. “Yes ma’am.”
“Don’t call me that.” Katsumi cringes.
“Okay, Tsumi-sensei!”
“You know what? Just call me either Katsumi or Bakugo. None of that Tsumi-chan shit.”
“I’m sticking with Tsumi-chan!”
This… is going to suck.
-
It’s four when Emiko finally arries, dressed in the school’s uniform, the school's letters written on it in bright white against the blue, bouncy hair up in a high ponytail atop her head, gleaming with joy. Her hair looks like a bouncy, happy baby plant when she jumps up and down, too hyper to even stand still. “I’m ready for my training, Tsumi-chan!”
Katsumi finishes throwing all the gym mats to the side–which had proved itself to be a rather daunting task–she turns back to Eiko, spiky blonde hair flying into her face. “Alright Planthead, we are going to work on physical strength first.” She brushes her hands and places them on her hips.
Emiko furrows her brow. “Do you mean showing how much I lift? Cause it’s not a lot.”
“No,” Katsumi sys. A foot shifts behind her and raises her hands in front of her into fists. “We’re sparring.”
Shock immediately hits Emiko. “Wait, we’re sparring?” I thought we were working on my accuracy, you know, pew pew pew.” Emiko says, making finger guns.
Katsumi drops her hands. She’s almost disappointed by her reaction. “Of course we are. I have to see what I’m working with here.” She says before preparing herself in a fighting stance.It would be good practice for Emiko and herself. It's been a while since she had spared against someone that wasn’t in her family. “C’mon, let’s spar.”
Emiko nods reluctantly, shifting a foot behind her. “Okay. I’m ready.”
“We go on the count of three, okay?” Katsumi asks, palm beginning to spark with small explosions. “Quirks are fair game.”
“Wait.” Emiko says, relaxing her arms and letting them fall to her side. Katsumi drops her own in irritation, not before flailing them up. “When you say three, or after you say three?”
Katsumi stomps a foot on the ground so hard the walls shake. “What’s the damn difference?”
“Some could have a head start! You never know! I want this to be a fair game!”
Katsumi throws a hand on her forehead and rubs her temples with her fingers. Aggression was coursing through her veins and she was almost positive that the next thing that would come out of her mouth would be a swear or a loud “DIE!” She takes a deep breath in hopes it would flush the anger away–it worked a bit, at least–before digging a hand through her pockets. “Here,” she says, pulling out a coin, to which Emiko stares at. “I’ll throw this up and once it hits the ground we start.”
“Okay.” Emiko nods. “Who throws the coin?”
“Dumbass, it’s my coin so I’m throwing it!”
Emiko scowls, and for the first time, she actually seems something other than stupidly happy. “There’s no reason to get so mad, Tsumi-chan.”
“Whatever, Planthead.” Katsumi says with a roll of her eyes, coin in hand. “You ready now?”
Emiko nods enthusiastically. “Yep!” She glances down at her shoes before looking back up with a bright smile. “All ready!”
“What were you just looking at?” Katsumi looks down at Emiko’s feet. Just white sneakers–they looked like they were freshly bought. “What, making sure your shoes were clean?”
“No. Making sure they were tied.”
Katsumi shakes her head vigorously. She could handle this. She had inherited her mother’s patience for a reason. But if she inherited her mother’s patience for this exact reason, she might just kill herself. “Fine. Let’s just start.” She says with a restrained tone. “First one who taps out or is fully restrained loses.”
Emiko nods again. “Okay!”
Was her skin always dark like that?
Katsumi tosses the coin into the air. It falls almost in slow motion, and once it hits the ground, Emiko throws herself forward. She’s fast! She manages to dodge just in time, swiveling a foot so Emiko falls into nothing. It was a simple trick her mother taught her–she taught it to her when she was in her teen years. It was a move Gunhead taught her when she was interning.Her hand grabs the wrist closest to her, leading Emiko to the ground.
Good. Now to–
The black shadow makes its appearance again, connecting Katsumi’s arm and Emiko’s wrist. Wha– Emiko throws her hand back and Katsumi’s hand yanks backwards along with it. The shadow disappears as soon as it appears, and Emiko takes the chance to kick Katsumi in a split of a second, sending her to the ground. Her body bounces against the floor at the impact, coughing violently. Fuck, she’s stronger than she looks.
Katsumi blurrily looks up and her eyes widen when she sees a slim leg coming down. Shit. Her Fight-Or-Flight instinct kicks in and–surprisingly enough–she jumps out of the way, just enough for Emiko’s kick to land right near her head. She pushes off her hands and lands on her feet, crouched down at a low level. She's more suited to combat than I thought. Katsumi lets more explosions crackle in her palms. “Remember what I said, Planthead–” she smiles before she pushes her palms together. “Quirks are fair game.”
Emiko knits her brow together. “I know, I used–”
She’s cut off when a loud boom blocks out any sound, a large flash blocking her eyes before two hands take her arm, and quickly enough, she’s on her stomach with Katsumi’s hands pressing down on her wrists, both of them pinned at her side. Her legs are straddled against her stomach, both of them close enough to hear each other's ragged breaths. “You gonna tap out?” Katsumi asks with a smirk.
“I can get out of this.” Emiko says, bending her knees and resting her foot on the floor. “There’s a lot more I can do!” Her knee comes up to hit Katsumi in the back. She shouts out a swear as her grip loosens around Emiko’s wrists. She takes the chance to yank her wrists out of her hold and throw Katsumi off her. Katsumi flies into the gym mats before collapsing onto the ground. She slowly sits up and brushes her arm against the bruise starting to grow purple.
She smiles. “Okay. I see it now.” Katsumi says. “That Quirk of your’s–can you control it well? In terms of controlling how much you use.”
Emiko pauses from her stance. “No… not really. When I was a kid, sometimes it would come out randomly. I can control when it comes out now but I can’t control the amount that comes out.”
“That—that makes a lot more sense.”
“What does?” Emiko asks.
Katsumi walks forward and grabs her hand. Emiko’s ready to yank it forward, in anticipation of another attack when she holds her hand down. “I’m not attacking you.” She murmurs, fingers gently roaming across the palm of Emiko’s hand. “Just watch.”
Her fingers trail up her arm before she swoops across her forearm, the black shadow of Emiko’s Quirk floating up before returning back to its original state, settling like a second skin on Emiko. “Don’t. Move.” Katsumi instructs firmly. “This might sting—or tickle.” She focuses her attention on her hand and little crackles appear near Emiko’s skin.
She lets out a little giggle. “You were right, that does tickle!” Su exclaims, beginning to pull away her arm.
Katsumi yanks it back. Her eyes are laser-focused on her arm as she says, “Don't make me repeat myself, Planthead.” Emiko swallows and tries her best to stay still.
More shadows appear out of her arm, coming out in small strands. Her eyes widen in shock as more slowly starts to seep out, growing around Katsumi’s arm like a vine. She merely glances at it before her explosions get smaller before they fully disappear. There’s only the lingering feeling of Katsumi’s explosions as she rubs the tingling feeling in her arm away. Katsumi begins to walk away from her. “Planthead—“
“Are you gonna keep the nickname for me?” Emiko asks, still rubbing at her arm.
Katsumi tugs her sleeves up before turning to glare at her.”As long as you keep calling me ‘Tsumi-chan’.” She says in a mocking tone. With a little impatient wave of her hand, Emiko follows her gaze at the stacked up gym mats and sits on them. “Look dumbass, I’m not trying to be cruel—“
“I don’t think you’re cruel. I just think you’re mean at times.” Emiko clarifies.
Katsumi shakes her head. “Whatever, same thing.”
“There's a difference, Tsumi-chan. Cruel is being—“
She throws herself next to Emiko and quickly slaps a hand over her mouth. “I don’t need to hear the rest, trust me.”Katsumi says with gritted teeth. “Do you want to know what I noticed?”
“That Katsu and Yuki are dating? That Mitsuo wasn’t wearing his uniform jacket today? That—“
“Why don’t you let me do the talking for now?”
Emiko makes a “zip-my-lips” motion before throwing the imaginary key behind her. Katsumi takes a cleansing breath—for what seemed like the hundredth time this hour—before continuing. “Your Quirk is your father’s Blackwhip Quirk? Almost the exact same?” Emiko nods and Katsumi returns it. “Thought so much. Blackwhip—as far as I know it—is highly dependent on emoticonos. If you’d inherited the same kinds of aspects of the original Blackwhip, it should be the same. I’m not very sure what kind of emotions you were feeling during our fight, but when I grabbed your wrist, it suddenly grabbed me. That took me by slight surprise.”
“I suppose when I did get mad at that kid in kindergarten it grabbed him.” Emiko adds.
“Exactly. Most of the time, you do have control over your emotions because you’re always…” Katsumi looks at her. There weren't any words that could nicely describe her. “Excessively happy.” Is what she settles on.
“Excessively?” Emiko asks, scooting closer to Katsumi. She slides backwards in habit. “What do you mean?”
Katsumi clears her throat. “You get very distracted at times. It allows… you to not pay as much attention when something happens. In which case, when you are using your Quirk, it–” she pauses before putting out both her hands, trying to grasp the air in front of her. “When you’re using it, instead of focusing your attention on one thing, and your emotions focusing on an object, you don’t think.”
“Uh…” Emiko puts a hand to her mouth to ponder before she extends it out in front of her, as if she was about to say something but nothing comes out. “Okay, I don’t really know what you’re getting at, Tsumi-chan.”
“Like that!” Katsumi extends out an excited hand. “You don’t think, so your Quirk has nothing to do! When you activate it, it just rests on your body. And since Blackwhip is significantly stronger than your base muscle strength, it makes you stronger!”
Emiko blinks and Katsumi falters. “Right?” She only gets a shrug in response. Katsumi frowns and runs a hand through her tangled hair, pulling out the rubber band holding up her ponytail. “Oh, shit. I thought I was onto something. I mean your Quirk, it seems so much like his–fuck, I thought–”
“No, no.” She interrupts, a serious look on her face. “I think you’re right.” Emiko pauses. “Maybe. It’s reasonable enough. But there are also a lot of possibilities.”
Katsumi sighs. She stands back up and brushes a speck of dirt off her shoulder. “As we figure that out, let’s work on your accuracy.”
Emiko stands up along with her. “Wow. You found that all out during our fight?”
“If I were really trying during that fight, I would’ve injured you and found nothing about your Quirk.” She responds, taking out a couple more coins from her pocket. She throws them up, and as if to solidify her words, explosions go off on each coin, small parts of metal flying to the ground. She turns and flashes Emiko a smirk.“We can have a real rematch when you master that Quirk of yours.”
“Yes, sensei!”
“Don’t–ugh, why do I even try.”
