Chapter 007 Part 1:
Leaping her way into his heart!
(or D breaks into the Mature rating and regrets nothing and everything at once)

"You know; this is harder than I thought it would be." D said with her face against the asphalt, where it would always end up being according to the law of probability. The nice Heal-Heal Lady hired by All Might said she should try and not do that please, but it was out of her hands, the world needed her to hit the ground with her head or it would otherwise simply not be quite as it should.

Overhead, The Crawler was slowly floating in the air towards her, having finished fixing the broken sign of the nice old couple and receiving some candy for the trouble.

"It's not, actually." the bastard said with a straight face while popping a candy into his mouth, "You have to put less power on it, you're going full throttle when you have to juuust do it enough to counteract gravity, and maybe go a little bit in the opposite direction if you overshoot."

The girl looked up at that and glared at the man who dared to throw her own explanation back to her own face, as if it wasn't her that explained it to him. So she complained about the unfairness of the world.

"But that's exactly the problem! I can only do a glacial crawl or full speed ahead, no in between!" she grumbled even when she was given one of the candies as a consolation prize, "I don't wanna copy your ability anymore, I will crack my head open…"

Koichi visibly relaxed at that, letting his body go slack and sighing in utter relief.

"Maybe practice with another Quirk?" he offered.

"Yeah, I just never had powers before, so I don't have a good handle on them yet. Gotta find a safe one and practice control… HEY, POHP STEHP!" she shouted while munching on her candy.

Pop Step, who was previously lazing around on top of a street clock, was startled from the shout and fell, but managed to correct her descent and land on her feet, though she winced at the impact.

"WHAT DO YOU WANT YOU BRAT?!" she screamed back, though D had already forgotten the original reason.

"Did that hurt?" she asked, more curious than concerned, "Don't you have the Leap-Leap Fruit?"

"Humph, it's just Leap, and it only works if I purposefully begin a jump and land on my feet. It doesn't work with natural falls." she explained, annoyed at her antics.

"And you don't feel the force from your legs hitting the ground at all when you do? But the stuff you land on does?"

"…Yes?" she responded to the weirdly specific question, afraid of the reasoning behind it.

"Can you kick people with all your strength without feeling anything after a leap? Or just kick a person and call it a leap?" D asked while approaching the idol.

"I… Yes to the first and… I think that the answer to the second is a no, unless I actually leap after the kick..." Pop said, having a feeling of where the conversation was going.

"What is a Leap, anyways?" she asked as she poked her in the head after a jump to reach it, copying the Devil Fruit in the process.

"…A jump?" the woman tried while going cross-eyed to follow the movement, never having questioned it before.

"And what is a jump?" the girl asked while doing a handstand.

"Uhhh… That is a weird question, give me a moment." she said before taking her phone out and searching for the definition. "A 'Jump' is defined as pushing oneself off a surface and into the air by using the muscles in one's legs and feet."

"Well, first off, you're wrong." D demonstrated by doing a hand hop and flying into the air before landing on a handstand again. "I just jumped with my hands and was still able to use the Leap-Leap Fruit."

"You can do that?!" Pop Step asked, mystified, never having tried to do so before.

"Second, you're also wrong." she did another hand hop but landed on her head this time, not even wincing from the impact. "Your perception of what constitutes as finishing a leap is misguided. You said you needed to Leap with your legs and land on them, but I just did it with my hands and landed on my head. This is because I'm magic, and while logic dictates that I should end a Leap by landing, it was never specified I had to do so to allow the cushioning effect to happen."

"But… but…" she tried and failed to counter the clear evidence that was telling her that yes, that just happened.

"I don't fault your common sense, but common sense is overrated when Devil Fruits are involved." D consoled her clearly inexperienced apprentice. She punched the ground, achieved nothing, opened her hand like a spring and still nothing happened. "I guess that all parts of my body have to end up in the air for Leap to activate…" she murmured, going back to her feet and slowly raising a leg, to no result. "Yep, definitely have to be in the air…"

"I would be concerned if you could count something as a Leap if you never left the ground in the first place…" Pop Step whispered, perplexed at D's experimentations.

"Third and final, you're definitely wrong." D said while preparing herself, making sure there was nothing in front of her. "For you see…" She gritted her teeth, preparing her legs for the immediate ordeal. "Who said you can only Leap once before taking off?!" She did small fast hops in place, firing herself up. "Why can't you stack them to reach further heights?!" She began kicking the ground with both her legs, never touching the ground for more than one second. "And most important of all…!" she stopped moving in the middle of the air, before kicking multiple times with all the speed she could muster in a show of explosive force! "WHICH SIX POWER AM I ABOUT TO SHOW YOU?!"

D practically disappeared, leaving an after-image and a dust cloud in her apparent path. Following the rush of displaced air, they could see a blur moving at extreme speeds in the distance some streets ahead… Before it tripped and began rolling on the ground… and continued rolling even more. She actually traveled more distance in that roll than with her monstrous Leap.

"I'm okay!" she shouted with a thumbs up, "The cushion effect still works!"

Pop Step gawked at her, then pinched her cheek in case she was dreaming but the results were still there. The girl had just traveled more distance than her best Leap from flat ground almost instantly, and apparently did it using her own Quirk.

"What was that?!" Koichi asked, because she was too shocked to formulate a word, much less a sentence.

"Oh, see, there's this thing called Shave? Or Soru? You're supposed to kick the ground ten times in the blink of an eye and you go woosh!" she explained with an energetic smile, as if it was a realistic thing to do and not pure insanity, "But I'm not fast enough for that. However, since Leap is a thing, I thought that if I managed at least two kicks I could get similar results and it worked!" she threw her hands up in the air and laughed, content in her accomplishment.

"Wanna try Pop?" D asked the rapidly paling woman, who was shaking her head in denial like her life depended on it. It might very well do. "Eh, your loss." She Shaved again, this time managing to only roll for a whole street instead of seven.

"…Now you get how I feel." Koichi told Kazuho who nodded numbly in response, both now sharing the pain that was D. She tried to Shave in the air (otherwise known as a Kamisori), failed and face-planted on the concrete. She gave a thumbs up though, the cushioning effect being really handy.

After some more Shaves, tripping over a can and rolling for a whole kilometer, D called it a day with that particular Six Power. She would have to try and recreate the other five later in the future… actually, didn't The Crawler already reinvent Geppo/Moonwalk with his bursts of air? Damn she worked fast, only four to go.

"So, what are we doing here anyways?" she asked, only now realizing that she wasn't sure what Vigilante activity they were doing.

"Picking up garbage." The Crawler answered while putting a stray can in the trash backpack he carried.

"Ahhh, I see." D said, not seeing it. "Is that what Vigilantes are supposed to do?" she asked, disappointed.

"It's what I want to do, and I'm a Vigilante. You don't have to if you don't wanna, I did say it was a hobby after all and doing something you don't like as a hobby defeats its purpose."

"The little demon has a point though," Pop Step chimed in. "Don't you want to be a hero? Picking up garbage is so uncool and nobody cares if you do it."

The Crawler didn't hesitate with his answer, having already answered it before.

"Nah. Stopping trash collecting just cuz it isn't cool? That's not what I'm about." he briefly looked at D's confused expression and expanded. "I'm a Vigilante because I can't be a Pro Hero, that's what it means to me, that's my dream. Pop Step is a Vigilante because she wants to Leap around during her concerts, and Sensei is a Vigilante because he likes punching people in the head. We're all Vigilantes, but for different reasons… Yet we're together because we all share that. I can't tell you what to do as a Vigilante, it's your choice, just like it's my choice to do the right thing and pick up garbage because nobody else will do it." he said while picking up another can and throwing it in his garbage can.

D, who was confused because did Pop Step just blush? ignored most of the deep speech, having already understood the Pirate-Dream-Vigilante-Choice parallel.

"Uh huh, I see, good talk Koichi." she said while linking her arm around Pop's legs, mostly because she was short. "I've gotta go to the bathroom real quick, I'm taking Pop Step with me, bye."

Before she could protest, D Shaved multiple times into the distance, before falling into a heap of limbs that touched places that shouldn't be touched this early into their relationship.

"WHAT THE HELL D?!" Pop shouted into her crotch. "WHAT WAS THAT FOR?!" she asked after managing to escape her tiny grasp and standing.

She looked up at the young woman, pointed her finger at her face and in her most annoying little kid's voice she sang.

"Pop and Crawler, sitting in a tree, K-I-S-S-I-N-G!" she chirped while suddenly evading swipes to the head from an embarrassed idol, "First comes love, then comes marriage, then comes a bab-" Pop sucker punched her in the face. "-y, in a baby carriage!" she finished, having been hit mid-Leap and thus cushioning the punch by counting as landing on the fist. "Uh, would you look at that? I didn't know I could do that…'' she was then punched in the face again, this time while touching the floor. That one wasn't cushioned.

"Was that all?!" the Leap Woman furiously asked, her patience running out. "Because if you sing that in front of Koichi…!"

"He wouldn't get it." D informed her from the ground without bothering to get up, all cheer leaving her voice. "He's so dense that you could tell him you love him, and he would say 'Thank you, I love you too!' and move on without thinking about it."

Pop Step stopped her rant, caught off-guard by the sudden shift in tone and she wasn't sure of where this was going.

"You know I'm seventeen, right? I just look like a child. Koichi knows, so I thought he already told you." she said, and judging by her surprised expression she wasn't aware. "I was just teasing you earlier, but also I want to give you some advice you will absolutely need if you actually want to end up with Koichi. Advice that I wished I could have given to another woman who once pursued a similar man named Luffy."

"Luffy… you said that name earlier, didn't you?" Pop mentioned while sitting next to her, remembering their first meeting as she took out her phone to type something. "You thought Koichi was Luffy."

"Yeah… They really are alike in a lot of ways." she admitted. "If I never manage to see Luffy again, I think Koichi could fill that void in my heart."

Pop Step hummed at that while mulling the not-so-subtle meaning behind them, letting D think how to word what she wanted to say.

"If I could have talked to that woman… I would have told her to go for it, except she already did. She showered Luffy with affection and love, fanned over him day and night and swooned at the very sight of him. She was madly in love, and everyone knew it… except Luffy himself." she complained, expelling a suffering sigh, "No matter what she did, he just didn't get the hint! He even saw her naked and still didn't get it!"

Pop Step looked weirdly at her, but she carried on.

"She could cross the seven seas for him and go against the entire world, and he would only think how lucky he was to have such an awesome friend! It was so, so… infuriating! So frustrating! Can you imagine how she felt, Pop?!" she asked, getting herself worked up over it once again.

But Pop was oddly silent and giving her a calculating gaze, like she was seeing her in a new light.

"And when I think of that woman, I can only think how it all could have been prevented if she had simply asked in a clear way, communicated properly through his thick skull what she really meant! Even if the answer had been no, at least then she could move on." she eyed the young woman beside her. "What I see in her, I see in you Pop. Koichi is like Luffy, so if you want to act on that crush of yours, my advice is that you take the initiative and be loud and clear about it. No hints, no indirect signals, just ask him out, then ask again because he may not get it the first time."

She rested her back on the floor and looked up at the sky after finally getting her worries out of her chest. She just couldn't tolerate that 'will they won't they' crap, so at the first hint of that type of romance from Pop Step she just had to take her aside to prevent it. If even with that rant they didn't get together, then she just didn't know what to do. Stupid unresolved romances… Stupid Boa Hancock… Stupid, possibly asexual and aromantic Luffy…

"Hey," Pop Step waved after laying on the street with her, "I… Was I that obvious?" she asked while blushing and fiddling with her hands.

D snorted. "To Koichi, absolutely not. To me, it was fifty fifty between you being in love with him or just being really shy around boys sometimes, but considering your outfit and chosen profession I doubted it."

Pop punched her in the shoulder, but it had no heat behind it. Her phone did a little chime and she checked it, only to reel back in surprise and furiously tap a response.

"Wow, either Koichi is more gullible than I thought or you really are seventeen." She commented after another ding, surprised that he confirmed it.

"Nah, just body switching shenanigans." D said, because she knew reincarnation was too out there and technically it was true. "I'm fine with it though, makes everything funnier."

Pop Step hummed at that, before sighing and returning to their previous topic.

"I… I know Koichi from long ago, but he probably doesn't remember me." she admitted, telling her side. "He saved me when I was little, and only recently did I meet him again. I… I'm not sure if I love him, or simply admire him for who he is. I don't know if we are compatible, and I'm afraid of ruining what we already have. I don't know what a relationship with him would be like, or if I'm really girlfriend material. I want him to be happy, but I'm not sure if he would be the happiest with me, or if there's a better option for him around the corner. I'm afraid that he could leave me for someone more attractive, or smarter, or heroic… Especially someone more heroic. I'm also afraid of what could happen to him if he continues being a Vigilante, if some rule zealot will take it too far and arrest him for just trying to be a good person. Or worse, what if he takes on some powerful Villain and loses, what if he… what if he dies, without me having told him how I really feel. But if I tell him and we get together, then it's going to hurt all the more if I lose him. And if we are together, I feel like I would nag him to not put himself in danger and shackle him down, limit his dream and make him miserable. I just… I don't know what to do, so it's easier to just leave it for later."

Pop Step poured her heart out, expressing all the little doubts that plagued her mind, all the what ifs and maybes she thought every time she put on the hoodie a kind Hero had given her as a little girl. She only realized she had been crying when she noticed D was on top of her and wiping a tear away, then laughed bitterly when another took its place.

"God damn it, my makeup is ruined," she complained while scrubbing the black paint out of her face, exhausted and drained. "I… I just wanted to share with you like you shared with me and now I'm a mess… I hope there aren't any cameras around or my popularity is going to take a hit, why did I do this in the middle of the street… Shit, Koichi is waiting for us and I don't have my kit on me, how am I gonna explain this to him…" she continued in her downward spiral, finding every little way this talk had gone wrong.

D, who still had her hand on Pop's face, softly pulled the young woman's cheek and was rewarded with a tired ow and a glare.

"You're being silly," she told the idol, "And as my new Nakama, it's my job to set you straight. Come on, get up." she said while offering a hand, "We're gonna get you cleaned up first thing first."

Pop Step took the hand and rose up on wobbly legs, relying on D's support to stay standing.

"Wow, I'm worse off than I thought." she tried to joke.

"Come on, there was a public bathroom some streets ahead." she informed her while beginning to walk, forcing Pop to match her pace. "We're gonna wash that cute face clean, then you're going to buy new makeup at the nearest store because I don't have any money on me, or in general really, and I'm gonna reapply it for you. Then, we're going back to Koichi and telling him I accidently embedded myself on a wall and you had to dig me out, which is why we were late."

Pop snorted, mostly because that could have actually happened. Then, in a softer tone, the deceptively young woman continued.

"I think a lot of your worries are reasonable, but also some of them feel like excuses to not try." she told her, and her good cheer evaporated. "And from your reasonable worries, some you simply won't know unless you try and experience them first hand. But I do know this!" she said, waving her finger in front of her face, "Don't you ever doubt you're the best woman for Koichi!"

"But-!" she tried to explain-

"No doubting!" D interrupted, "If your dream is to be his girlfriend and for him to be his happiest, then you're already the best option because you truly care about him! There may be other options that have different qualities, but you have the most important one!"

"But if someone better comes along and loves him-!"

"Who cares about it?! That only means you gotta work harder to be the best option for him! Besides, you're forgetting a very crucial detail!" she clicked her tongue, disappointed in her still not seeing it.

"What could possibly-?"

D stopped Pop Step in place and made her kneel, which she complied despite not knowing why. She then put both her hands in her cheeks like she was about to pinch them again, but pulled them upwards instead.

"You, silly!" she said while forcing her to smile. "You're forgetting that you also matter! That your happiness matters! Honestly, why do all my Nakamas struggle with something so simple?!"

"I… what?" Pop Step asked, finally listening to D's words.

"You're treating being in a relationship with Koichi as doing your best to make him happy, but you forget that it's a two-way street!" she shouted in her face, "Just as you try to make him happy, he will try to make you happy too! Because being happy together is the point you aren't getting through your thick skull! Who cares if theoretically there were better options that could potentially make him happier?! He would already be happy with you and you would be happy with him, and that would be all that matters! Happiness isn't something you can't quantify, stupid!"

"I, but what's best for him-"

"What's best for him?! What's best for you?! If Koichi likes you even by the smallest bit as a platonic friend, then you putting yourself down like that will make him sad! Sad, you hear me! That's the opposite of happy! So stop being sad for him, and ask him out already! If not for yourself, then because Koichi will be sad! You don't wanna make Koichi sad, do you? Because that's what you're making him be! Sad! Sad and teary eyed and snotty faced because his bestest friend in the whole wide world isn't taking care of herself properly!"

"We have been friends for less than a month…" she whispered, and D just had enough of this nonsense, even Toshi wasn't as hard-headed as her, so she decided to take drastic measures.

"LOVE CARES NOT FOR TIME! Just fuck his brains out already or I WILL!" D screamed without thinking and Pop Step gasped, scandalized. D then decided to double down and say that yes, that was actually quite the good idea. "YES, THAT IS A THREAT! If you don't even TRY to ask him out by the end of the year, I will do it myself! We will be sweethearts, kiss and lick the inside of our mouths in front of you, grope places that shouldn't be groped in public while you watch and send you a video of our first time so you can miserably touch yourself to it as you cry in regret!" the innocent idol's face turned cherry red and she tried to look away, but D had her head firmly in her hands and didn't allow it. "That is a promise, and I never break my promises unless I'm lying, and I'm not! Do you want that to happen Pop? DO YOU? ARE YOU INTO THAT STUFF? Because if not, then better start working on that confession, because the clock is ticking! One year Pop, ONE YEAR!"

She freed the young maiden's head and continued to walk forwards while tugging her along by the hand, fuming at her indecision.

"Now come on, I gotta reapply your makeup so you're all nice and shit so Koichi falls head over heels for you." she told the silent statue, who could only gape at the foul-mouthed girl. "Fuck! I don't want to date Koichi, he's a dumbass, why did I promise that?! This is all your fault, now I'm going to have your wingman or something so we don't end up all miserable!"

"I thought you loved Luffy?" she managed to squeak out. "And he's like Koichi?"

"What?! No, EW, he's an even bigger dumbass! Why would you think that?!" she asked, perplexed at the non sequitur.

"The woman…"

"Was Boa Hancock. Did I not mention that? I thought I mentioned that." D wondered to herself how could what she said possibly lead her to believe she loved Luffy in a non-platonic way. She wasn't sure if Luffy even knew what to do with his lower parts.

"I… I give up." Pop said, downtrodden.

"I WILL STRIP YOU NAKED AND THROW YOU IN HIS BED WRAPPED UP LIKE A PRESENT IN BONDAGE, YOU DO NOT GET TO GIVE UP ON YOUR OWN DREAM!" D roared in indignation at Pop Step giving up her dream so easily, and some primal fear at the thought of dating Koichi.

Pop Step shook her head, done with everything and just being unable to process anything else.

"Hey, is everything alright?" The Crawler appeared around the corner. "I heard shouting and-"

"EVERYTHING IS FINE AND DANDY, NOW FUCK OFF! WE WERE HAVING A NICE AND QUIET GIRL TALK OVER HERE AND YOU'RE NOT INVITED!" she snarled and growled at the intruder, who wisely decided to back off in reverse.

"AND YOU!" she shouted while pointing her finger straight between the eyes of the indecisive bitch that was also her new Nakama, "You! You…!"

D sighed, reaching the point in her rage where it shimmered into a cold hate for everything in the world, but without the will to do anything about it besides being bitter and snarky.

"Let's get your fucking makeup on already."

Pop Step totally rocked that eyeliner, and D was goddamn proud of her handiwork.

Chapter 007 Part 2:
True Man's third-third interview
(or how absurd One Piece is in retrospect, especially when explained by a four-year-old)

"And then I spent the rest of the day picking up trash and hitting Pop Step with my elbow every time she blushed, which was literally each time their eyes met." she retold her handler, because she was a menace to society and had to explain why there were multiple holes in the walls of Naruhata now.

The True Man simply wrote down her statement without questioning, knowing that everything she said was technically true. After she finished, he tapped certain underlined sections and began the interview proper.

"First of all, I want a radiography of your skull in case of fractures and to determine how truly thick it is." he asked without a hint of an insult, just pure medical curiosity. "I also want you to wear a helmet, but I'm afraid of you copying a Quirk that will grow your head to see if the helmet will grow with you, so let's shelve that idea for later. And for later, I mean never D, wipe that thoughtful look from your face, it was a threat not a suggestion."

He flipped through the notes until he found more underlined text.

"I would ask you for a list of everything you know, but I feel that I couldn't possibly endure so much concentrated insanity, so I will deal with just knowing about the Six Powers for now. Begin."

"Oh, so you already know about Shave, and Moonwalk is kicking real hard the air and the shockwave makes you fly," Naomasa nodded at that, aware that All Might did the second one. "There's also Tekkai, or Iron Body, which is locking your muscles in place and somehow becoming denser? I guess it's like those people who move their stomach weird and can take any hit to it." she said unsure, while Naomasa added that the Iron Shirt was a real thing and probably more effective than thought.

"Then there is Rankyaku or Tempest Kick, where you kick so hard and fast that you make a sharp air wave that cuts everything in its path." Naomasa added 'All Might air punch variation' to the list. "Then there's Shigan or Finger Pistol, where you jab a person with your finger like a bullet." Naomasa added the Shaolin Finger Jab being real. "And then there's Kami-e or Paper Art, where you relax your body and become like paper, being incredibly flexible and avoiding any attacks, even being able to float on the wind or bend and contort your body in impossible shapes." Naomasa hesitated, then wrote 'if being high and thinking you're a piece of paper worked.'

"Well-"

"Then there's the Seventh Power!" she said, like that made sense. "Rokuogan or Six King Gun! You have to master the other Six Powers before even being able to perform this one. Let's see… you use Iron Body and Paper-Art to balance strength, immobility and flexibility, you prepare with the concepts of Moonwalk and Tempest Kick to feel and affect the air around yourself, then Shave to compress all the explosive movement into one single action, and wrap it up with Finger Pistol for the mentality to turn oneself into a living weapon that is about to utterly destroy your opponent in an instant. This all results in an overpowered One Inch Punch! Even a Rubber Man almost immune to blunt trauma was seriously hurt by it!"

The True Man thought about it, then simply wrote down exactly what she said word for word to process at a later date. All of what she said was, of course, the truth, or at least she thought so.

He feared the answer to the next question, but knew he had to ask it.

"And you discovered this information how exactly?" he asked, because most of those techniques sounded quite plausible, and the girl herself had performed two of them already.

"In the historical manga!" she said, her cheat card to evade all questions that was also the complete truth. "They were used by Cipher Pol Number 9, a group of undercover assassins."

The detective tensed at that, unsure if those people were a current threat, a fictional group or a plan for the future from her cult. Directly asking D wouldn't give him a satisfactory answer, so instead he silently gathered information.

"There's the Giraffe Man with two swords who uses his neck as another sword, the Bubble Woman who sometimes is a ram made of bubbles, the Leopard Man ventriloquist that talks through a bird, the Door Man who has the hair of a Bull Man but isn't one, the Wolf Man who has a mustache that sometimes is there and sometimes is not, the sea weasel guy who's not actually a Sea Weasel Man, a round guy that looks like a circle and has a zipper for a mouth, and a guy with a wild mane of hair that likes to say it's like a lion and gets mad if you compare it to an octopus." D dutifully listed, knowing that giving descriptions would be much more useful than names, since the assassins could simply use fake ones. She wasn't sure how they could end up in the past, but she wouldn't put it past them.

The True Man hit his head against the table at all that nonsense being true before dutifully writing it all down and preparing to make files on the suspects, putting an alert for any person that matched those… colorful descriptions, just in case they were actually real.

"Oh, and I guess there's Funkfreed too." she added, "He's a sword that ate the Elephant-Elephant Fruit, so he's an Elephant Sword, because the fruit comes before your species."

The detective's hand trembled as he wrote down that last bit of insanity that he refused to believe was true despite his Quirk telling him otherwise. He had heard of animals with Quirks, but objects with Quirks? That was too much for him to handle, so he compartmentalized the knowledge to the darkest recesses of his mind while flipping through his notes.

He sighed as he reached the part where he had underlined, circled and added exclamation points just to make sure he would ask this. He deserved all the coffee breaks in the world after this, at least this was the last question… He wasn't even touching the bet she made with a ten-foot pole, that was solely her mess, which wouldn't even be illegal depending on her answer.

"So… you're seventeen," he stated, secure in the knowledge only to be so wrong.

"I'm four years old." she told him, and he could already feel a migraine despite it registering as true.

"But… you told me you were seventeen earlier, and that was true back then."

"I am both four years old and seventeen years old." she said with absolute confidence, and the True Man wanted to cry. "I'm also zero years old too."

He did cry. The police chief almost charged D of torture and sadism. Toshinori had to come down to the station and console him. They then had ice cream and he felt better. It was a good day, his mind said after erasing the events before his friend visited without a real reason.

(Seventeen is mental age (debatable), four is apparent biological age, and zero is age since inhabiting this body. Of course, D failed to mention the body switch detail, which makes her words sound like insane ramblings.

Wow, D is making all her new Nakama cry. What an asshole.

Did Pop Step just learn Shock Nullification? Yes, she did. D demonstrates the difference of One Piece's creative 'It's my power and I decide what I get to do with it,' versus the biological limitations of MHA, and manages to break the barrier through sheer ignorance of how that's just not how it works here. Fear her, for she will kill herself and everyone around her one day, so pray to not be in the blast radius and weep as you realize it encompasses the whole world.

Also, D develops a potty mouth as she rages against the pussy-footing romance of her new Nakama, which is bound to continue as she's 15 and Koichi 21. That is not my complete opinion on that type of romance, as I utterly love Kaguya-sama Love Is War, which D didn't watch, and there are a lot of good shows that do that 'will they won't they' good. D just watched a lot of bad ones and gave up.)
