Yoichi told his brother, "I don't think a quirk that can let you speak to ghosts exists."

As usual, Hisashi didn't react. Hisashi could not see or hear him. Yoichi had started haunting his older brother shortly after his death, when he'd woken up as a vestige inside One for All. It was a painful and unrewarding endeavor, watching Hisashi commit even more grievous crimes as All for One with no way to stop him. No matter how Yoichi screamed and begged his brother, Hisashi would never know. Yoichi had quit haunting Hisashi several times, each lasting a year to a decade. Ever since his horrible brother had somehow managed to acquire a wife and child, Yoichi had preferred to watch them instead. He couldn't possibly miss a moment of his adorable nephew's childhood. Not like his worthless big brother who barely visited his family due to his preoccupation with villainy. Izuku was far cuter than Hisashi. But inevitably Yoichi kept coming back to watch over his older brother. It was as irresistible as picking at a half-healed scab or poking his tongue at a missing tooth.

Currently, Hisashi stood over the toad man on the warehouse floor. Red light crackled around Hisashi. The toad mutation gave the man bulging eyes sticking out even more than normal as he apologized for failing his master, begged for his life, and offered up his quirk.

Yoichi said, "I think he's just screwing with you. Ghosts don't exist, so why would a quirk that can see ghosts exist? I know I exist, but I'm an exception. I was created by a quirk. I've never met another ghost before, and I've been hanging around you for a century now. At the rate you kill people, I'd think you'd attract at least one vengeful ghost. Also, this man has a toad mutation. What does that have to do with seeing the dead? I know mutations don't always correlate with quirks but Occam's Razor says he's lying."

Even though Hisashi could not hear Yoichi's words, he parroted them: "That sounds like a lie." A cold smile curved on All for One's lips as he stood with his hands in his pockets, acting as if the sobbing man on the floor had nothing to do with him.

The toad man cried, "I never knew I had the ability before! I thought toad was my quirk! But there's a white-haired ghost with green eyes right behind you."

Both Hisashi and Yoichi froze. Slowly, Hisashi turned around and looked right at where the toad man pointed. For the first time in over a century, Yoichi's older brother looked straight at him. Hisashi's hungry gaze stared through Yoichi without seeing. Even so, Yoichi floated backward nervously.

Hoarsely, Hisashi asked, "Does he have great hair?"

"Amazing hair. He could be in hair commercials," the toad man babbled.

Hisashi's hand shot forward, fastening over the man's slimy head. His victim screamed as red lightning lanced over his face, his quirk sucking out of his body. Yoichi gaped, still in shock.

Turning around, Hisashi looked at his little brother. This time, their eyes met. Hisashi's eyes widened with delight. A breathtaking greed filled them. Without glancing at his minion, he said, "For this great gift, you may consider yourself forgiven."

Tears streaming down his face, the toad man ran from the warehouse. Hisashi did not watch his minion depart. His gaze remained fixed on the stunned ghost. A smug smile on his lips, Hisashi purred, "It's been too long, little brother."

That smile roused an instinctive panic in Yoichi. He shot backward across the warehouse. Every nerve screamed to run, to vanish. But the realization that he could leave straightened Yoichi's spine. As a ghost, his older brother had no power over him. For once Yoichi was in control of the conversation.

Crossing his arms, Yoichi said, "I have a lot to say to you."

"Me too," Hisashi breathed reverently, his eyes soaking in every last detail of Yoichi's form. "Are you a ghost originating from inside One for All? I'd speculated…but I'd hardly dared hope for this level of preservation. How long have you been around me? Do you—"

Yoichi interrupted, "You're a loser who spent the last century role-playing as a demon king. You still can't fasten a tie." His gaze swept his older brother's dark suit with the top unbuttoned. "In the last century I haven't seen you finish a single series that you pick up, whether paper or film. You don't have any friends. You probably became a mass-murderer because you're pathetic and unloved. Also, stop killing people."

Hisashi rolled his eyes. "Of course you speak to me for the first time in a century just to lecture me."

"I'm not done yet! You're a deadbeat father. Fine, you provide financial support, but it's been months since you last saw your son."

This time, a flicker of irritation or anger flashed through Hisashi's eyes. "If that's how you're going to be, then some time in the vault will—"

"Haven't you realized?" Yoichi crowed. "I'm a ghost! You can't lock me up in a bank vault!"

Hisashi scowled. "It was a slip of the tongue. You inspire the vaulting reflex in me."

"You can't run from me either." Yoichi circled around Hisashi. "I can follow you anywhere. You're stuck with me!"

"Oh, so after decades apart now you're eager for my presence again?" Hisashi asked, a trace of his cheer coming back.

Yoichi smirked. His big brother hadn't yet realized the painful reality of his situation. "Actually, yes. I've stored up years of little brother annoyance power. And I don't have anything else to do besides ruin your day."

Yoichi floated just behind his brother, a finger hovering a millimeter away from a suited shoulder. "I'm not touching you. I'm not touching you. I'm not touching you."

Hisashi rolled his eyes. "I see you haven't gotten the slightest bit more mature over the decades." He was playing it cool, as if Yoichi's threat was inconsequential. But when Yoichi had been a child, this trick had never failed to drive his big brother crazy. Yoichi was confident that Hisashi was only pretending not to be bothered.

"I'm not touching you. I'm not touching you." Yoichi darted up and down his brother's body, poking.

Face contorted, Hisashi whirled around and grabbed for Yoichi's ghostly form, his hand passing through.

Yoichi smirked. "I knew I could annoy you. I've still got it!"

Hisashi glared. "I could give up this quirk, you know."

That briefly silenced Yoichi. But he knew his older brother better than that. "You could, but you never will. It would drive you insane, knowing that I'm hovering around you but you can't hear me. Actually, if you gave up the quirk, I would probably just leave. I'd fly away out of your grasp. I bet you couldn't stand that, could you?"

From the scowl on Hisashi's face, Yoichi had won this round. Hisashi stomped out of the warehouse and got into his waiting car, grumbling, "Someday I'll get my hands on One for All, and then we'll see who's in charge."

"Pardon me, sir?" the driver asked, his confused eyes reflecting in the mirror.

Hisashi said, "Never mind, just take me back to the office."

As the car started moving, it became harder to not-quite-poke his brother, so Yoichi switched tactics. He started singing, "I know a song that gets on everybody's nerve."

Hisashi groaned. "Oh, don't you dare," he hissed.

Determinedly, Yoichi sang at the top of his lungs, "I know a song that gets on everybody's nerve, everybody's nerve, yes, on everybody's nerve. I know a song that gets on everybody's nerve. And this is how it goes. I know a song that gets on everybody's nerve, everybody's nerve, yes, on everybody's nerve. I know a song that gets on everybody's nerve. And this is how it goes."

By the tenth repetition of the song, Hisashi had started twitching. The terrified chauffeur drove faster.

By the twentieth repetition of the song, Hisashi was making growling noises low in the back of his throat. Nearly sobbing, the chauffeur said, "I'm sorry for the traffic, sir." He stepped on the gas pedal, running a red light.

When they arrived at the office, Hisashi threw open the door and stomped loudly up the stairs as if trying to drown out the singing. Yoichi, who had no need for air, didn't even pause to breathe. He projected his voice loudly as he followed after his brother.

In his office, Hisashi put in a pair of earplugs and turned on his computer.

Yoichi paused singing briefly to coo over the computer background: a photo of his five-year-old nephew blowing out his birthday candles. Honestly, how could big brother have missed the birthday party because he had a business deal? Izuku had been so disappointed despite all the presents his father had sent. Didn't Hisashi used to be the one who said that family was all-important? Yoichi had been there at the party, cheering and clapping.

Yoichi's reminisces faded when Hisashi pulled up a spreadsheet of business deals.

Time to thwart some villainy! Yoichi cracked his knuckles, and then materialized a pair of bagpipes.

Banjo was a skilled bagpipes player, and he'd showed Yoichi the basics. Yoichi was not skilled enough to play the bagpipes in any remotely musical way. However, he could produce an unearthly howling wail like a Scottish warrior terrifying his enemies on the battlefield.

The sound penetrated straight through the earplugs. Hisashi moaned and clutched his head.

Determinedly, Yoichi played louder, drawing out the long notes.

"Stop!" Hisashi cried. "Fine, no business today. Let's watch a movie. I'll even watch one of your dumb superhero films."

Yoichi hesitated. The little brother in him wanted to continue playing until he drove his brother insane. But the hero pointed out that he'd won a valuable victory. He'd stopped All for One from carrying out business for the day. For decades, Yoichi had wished he could protect the innocent from his brother, and now he had a chance—even if that meant suffering through brotherly bonding time.

"Can we watch All Muscle?" Yoichi asked hopefully.

"That All Might expy?" Hisashi shuddered. "Fine, but I'm pirating the movie."

As Hisashi started the movie playing on his computer, Yoichi materialized a chair and sat down next to his brother. His muscles never hurt from standing, but this put him at the correct eye-level to see the movie. It was a strange, nostalgic feeling. Yoichi had so many memories of watching movies with his brother as children. They'd curled up together on a ratty old couch. Now, even though their chairs were pressed together, their bodies could not touch.

Naturally, Hisashi could not watch the movie in silence. He'd always talked during movies, but an All Might-adjacent film brought out the worst in him. He criticized everything from the hero's costume to his fighting style. He pointed out the flaws in the CGI. He complained frequently that the quirks didn't make sense. When the villain finally appeared, Hisashi paused and grudgingly said, "That's a nice suit."

"Unlike you, that villain can fasten a tie," Yoichi said spitefully.

Hisashi stuck up his nose. "Ties are unnecessary and leave an opening for a hero to strangle you, but otherwise this villain has style."

Yoichi said, "The tie doesn't get him. He dies in a collapsing building in the third movie."

Hisashi spun around in his wheely chair and glared. "Yoichi! Spoilers!"

Yoichi shrugged. "As if you would ever have gotten to the end of movie three. You've never finished a series in your entire life! Two decades ago, you got the second to last episode of an anime and you still stopped!"

Hisashi sneered. "I'll finish a story when the endings stop being so dreadfully stupid and sappy."

Yoichi sighed. "Villain wins tragic endings do exist…but you refuse to ever finish anything so you'll never see one."

"They'd never live up to the perfect ending in my own head."

"I think you're just lazy."

The movie continued playing as the brothers argued. That, too, had been typical of their childhood movie nights.

That evening, Yoichi let Hisashi get ready for bed with no music or commentary. He waited for Hisashi to lie down in bed and turn the lights off. After lulling his brother into a false sense of security, Yoichi floated over and sat on Hisashi's chest.

Hisashi's eyes shot open. "Little brother!"

"I'm just indulging in some traditional ghost behavior," Yoichi said innocently. He tried to tap into some traditional ghostly abilities and increase his weight on his brother's body while sucking all the heat out of the room. He wasn't sure if it would work. None of his attempts to interfere with his brother had worked pre-quirk.

A line of frost formed down the window. Hisashi's teeth chattered. He tried to roll over, but couldn't seem to move. "Go away," he groaned.

Yoichi smirked. "What's wrong? Is it hard to sleep with someone watching you? Now you know how I felt about all the cameras in my room."

"The cameras were discrete. This is not discrete."

Yoichi poked his brother's cheek. "I'm not touching you. Hey, want to listen to my 'Captain Hero defeats Demon King' musical production?"

Hisashi moaned and put a pillow over his head. Very little sleep was accomplished that night.

The next morning, Yoichi woke Hisashi up by waving chains over his head and screaming "Woooooooooo!"

Hisashi sat up with a snort and a gasp. He looked at his alarm clock. "FIVE IN THE MORNING?"

Yoichi said, "Remember when you used to wake me up at odd hours in the vault to disrupt my sense of time? What was it you used to say back then? Oh, yes: 'Rise and shine, your wonderful brother is here to visit.'"

Rubbing his eyes, Hisashi asked, "Where did you even get those chains?"

"I made them in One for All's Void." When Yoichi had stopped by back home, he'd considered telling the others about Hisashi's new power. He'd known that he ought to. They'd all want in on tormenting Hisashi. But in the end, Yoichi hadn't. Hisashi had only tolerated his antics because he was so desperate to see his little brother again. There was a very real risk that if Hisashi got stuck with his seven worst enemies following him around then he'd pass off the quirk to some other sucker. Then Yoichi's fun would be over. Or at least, that was Yoichi's excuse. On another level, Yoichi knew that if his friends were watching him then he wouldn't be able to play the part of annoying little brother with such gusto. He would be forced to act like a stern hero confronting a villain instead. For reasons that Yoichi was not prepared to examine, he did not yet want to give this up.

Maybe if Yoichi got bored tormenting Hisashi then he'd let one of the others have a go. That sounded fair. They had all of eternity.

Grumbling, Hisashi climbed out of bed and got dressed.

When Hisashi started down the stairs, Yoichi tried another test of his ghostly powers. He threw himself in front of his older brother's face, trying to block his vision and trip him.

Hisashi walked straight through. "Nice try, I have several vision quirks."

Growling, Yoichi threw himself at his brother's body, attempting to possess him. Nothing happened, no matter how many times he tried.

Hisashi started the coffee machine, then made himself a bowl of yogurt with fruit on top.

Japanese ghosts could supposedly eat food left out as offerings. Yoichi swiped his hand through the cereal.

The yogurt curdled and the fruit rotted away. Yoichi laughed. "I did it!" For some reason, his stomach felt very satiated, too.

Hisashi looked at his meal with disgust. "Seriously, you won't eat at all when I tell you to but you're happy to eat my share of food when you don't need the nourishment any longer." He got up, tossed the bowl in the trash, and made himself more yogurt.

Yoichi touched that too, rotting it. Then for good measure, he spoiled the coffee too.

Hisashi pulled out his phone and spoke into it. "Send me ten pounds of yogurt and twenty cups of coffee. Yes, right now."

The food delivery pulled up shortly. Yoichi got through three bowls of yogurt before his stomach bloated. Five cups of coffee made him jittery. Yoichi lay on the floor twitching as his brother enjoyed his breakfast. "Let's call this one a draw," Yoichi muttered.

"That's what you say every time I win," Hisashi said, sipping his coffee.

"You always pretend you won even when you lose!" Yoichi raised his head off the ground. It immediately throbbed. "Ow ow ow…"

Hisashi said, "For some mysterious reason, your idea of winning always ends with you lying on the ground moaning in pain. That's what other people call losing, foolish little brother."

Yoichi tried to say something sarcastic, but his stomach heaved and gurgled.

By the time Hisashi arrived at his pet mad scientist's laboratory, Yoichi had recovered a bit. He floated along after his brother as they walked past the tanks of Nomu.

Dr. Garaki said, "I've been working on making this Nomu absorb punches."

Yoichi interrupted, "Hey, creepy doctor, did you know that the guy you admire so much once lost a fight with a goose?"

Hisashi twitched. "I did not lose that fight!"

"Master? What fight?" Dr. Garaki asked.

Hisashi faked a smile. With the heavy bags under his eyes, it looked like a deranged grimace. "I was thinking out loud. Please continue."

"Don't mind if I do!" Yoichi said cheerfully. "Big brother was only ten years old and eating some takoyaki that he got from a street vendor. He dropped the food on the ground and the goose pounced on it. Any sane person would have let the goose have the food, especially since it wasn't edible at that point, but big brother thought it was a good idea to hit a goose with his backpack."

Hisashi growled, "I see you're conveniently leaving out the part where you bumped into me and knocked the container straight in the goose's path."

Yoichi cried, "That was an accident! Also, as I recall, you bumped into me."

"As if, you were always the clumsy one and extremely jealous that I had money for takoyaki and you didn't."

"Because you scammed me out of my allowance in that rigged poker game. You deserved to get bitten by a goose!"

Hisashi shouted, "You're remembering wrong, the goose bit you."

Yoichi threw up his translucent hands. "Now you're just lying!"

"I nobly fought the goose off and saved you." Hisashi crossed his arms smugly. "You should be thanking me."

"Really? So if you hike up your pants leg, there won't be a goose bite scar?" Yoichi floated downward and tried to lift up his brother's pants, his hands going through.

Hisashi grabbed the bottom of his trousers to hold them down. "Hey! Stay away from my silk pants! If you age them like the yogurt, then you're dead! Deader!"

Dr. Garaki stared in total confusion. "Master…are you under the influence of some strange quirk?"

Hisashi straightened. A very uncharacteristic blush covered his cheeks. "You're quite correct, doctor. I obtained a new quirk yesterday and it has some…interesting side-effects. Perhaps I'll pass it off to someone I don't like if it doesn't behave."

Yoichi crossed his arms and sneered. "Like I don't know you're bluffing. You stuck me in a bank vault full of cameras rather than let me out of your sight!"

Dr. Garaki said, "I can prepare a Nomu for the quirk right now, master."

Hisashi grinned. "That's not a bad idea. Then I could ditch the quirk while I work, and take it back later when I want it again. Please get a Nomu ready. I'll come back later this afternoon."

Yoichi fumed.

Over lunch, Yoichi decided to test his brother's resolve. First, Yoichi stole Hisashi's sandwich, leaving moldy bread, wilted lettuce, and rotten ham. Hisashi, already expecting this, had a line of other sandwiches prepared.

After eating a few more, Yoichi reeled backward clutching at his nonexistent heart. "I feel so satisfied! As if my last wish has been fulfilled! My body…it's fading away…"

Hisashi pushed over his chair as he leapt to his feet. "Stop it! Wait!"

Yoichi hammed up his act, making his voice more reedy. "I see a light at the end of the tunnel…" He raised his hand up, reaching. "I must go toward the light…" His body floated upward.

"No!" Hisashi screamed, tears streaming down his cheeks. "No, no, no! You can't leave me again so soon!" Red sparks danced down his body, which meant he was looking through his quirks and finding none that could be used here. His face seemed to age a decade. "Please, little brother, don't go…"

Yoichi laughed, floating back down again. "Psych! Man, you should have seen the look on your face. I guess you don't want me gone after all. Even after all these years, I can still pull one over on you."

Chest heaving, Hisashi stared. His eyes were wild and haggard. "You…you…" His face turned crimson and scrunched up. "How could you? That wasn't funny at all! How could you be so cruel knowing how I suffered over your death?"

The smile dropped off Yoichi's face. "You know what's cruel, big brother? When you sent my boyfriend to the Void with half his face ripped off. When you murdered all my successors, that was cruel. When you nuked a city block to kill Nana and try to kill her teenage successor along with her, that was cruel. Don't expect me to pity you, villain."

Sneering, Hisashi adjusted his suit and righted his chair. "I've never expected anything of you since you betrayed me."

That sincerely stung. Yoichi glared. "We might disagree on who betrayed who. Besides, it's not as if you expected much of me before that. You always treated me like a fool."

"Was I wrong?" Hisashi asked coldly. He stalked out of the room without looking back. Yoichi followed anyway.

After that, Hisashi did not return to see Dr. Garaki or threaten to give up the ghost seeing quirk again.

The real test of Yoichi's abilities came later that day. Hisashi, sleep-deprived and in a foul temper, had hunted down a young hero with an interesting camouflage quirk. Although the hero blended in with the brick wall and dumpster, Hisashi stalked forward.

Yoichi had tried insults, poking, singing, and even bagpipes. Nothing had distracted his older brother from his quirk fever. In desperation, Yoichi shouted, "You abandoned your son just like how our parents abandoned us! You're a bad father!"

Hisashi stopped moving. He looked stunned, as if he couldn't believe his little brother had gone that far. The hero took advantage to sidle past, then run.

Yoichi crossed his arms. His voice wavered slightly. "It's true! You hated them for neglecting and abandoning us, but you did the same thing to my poor sweet nephew. I've seen him crying late at night and wondering if you left because he's quirkless."

The words made Hisashi stagger backward. He gripped the wall. "I've made certain that Izuku is well-provided for. I call him every weekend. I'm not like our parents!"

"That's better than them, but it's not enough to call yourself a father!" Yoichi shouted. "All the hard parts of parenting happen in-person. Getting your kid to school every day, cheering at school events, cooking dinner, arranging doctor's appointments, helping him with homework, hugging him when he cries—you can't do any of that from a distance!" Tears overflowed from Yoichi's eyes. He could not remain unaffected like with his usual annoyance tactics. It was too personal. "I know you're capable of being a good parent. You did all of that and more for me! You looked after me when I was sick and throwing up every night. I was far more work than poor Izuku, but you never abandoned me. Is that why you gave up on Izuku? Because you got parentified with me and you were too tired and burned-out to deal with another kid?" That was Yoichi's secret fear—that it was all his fault.

"I'd never give up on my family," Hisashi growled, his pupils wide.

"But you certainly seem less enthusiastic about family the second time around!" Yoichi shouted. "I couldn't get you to leave me alone, but you're content with getting pictures of Izuku in exchange for sending a check to your lovely, neglected wife."

"Look how it turned out with you!" Hisashi shouted. "Yeah, I got burned—when you rejected me, ran away from home to become a hero, and died! You gave me abandonment issues, then you mock them to my face."

Yoichi hissed, "Still stuck on that? Whatever your problem with me, you have no right to take it out on Izuku. He's a different person."

"Izuku has already been talking about wanting to become a hero. I know how it will turn out if he finds out about me. Clearly I did a terrible job raising you, given how much you hate me. I don't know what I'm doing wrong but it seemed like I'd be less likely to mess up Izuku if I stayed away."

"So it is because of me," Yoichi said, miserable at having his worst fears confirmed. "I never hated you, just so you know. I had to stop you. But I don't hate you."

Hisashi hissed, "I would have rather you hated me than you left me."

"Yes, you've always been like that." Yoichi sighed. "Then you're going to punish Izuku for my actions? That's not fair."

"It's not a punishment." Hisashi's shoulders tensed. "I had to stay away from my family to keep them safe. You died because you got caught up with my enemies. I couldn't risk that happening to Izuku."

Yoichi swallowed. He felt guilty, but also a rising anger. "If you're aware that your villainy puts your family in danger, then why don't you stop?"

Hisashi threw up his hands. "This again! As if I don't see your ulterior motive!"

"There's no ulterior motive, this time. I won't even tell you to stop being a villain forever. But you could take a break. You're immortal—what is a decade-long sabbatical to you? You could watch your son grow up." Yoichi wanted so badly to make this work, he strived to think of how to persuade his brother. "Do you still need One for All now that I'm here? If you go home and take a vacation from your business, then I promise I'll stay by your side. I'll stop poking you and playing the bagpipes. I won't eat your food unless you leave it out as an offering. I'll only spoil movies when you get excessively annoying about them. You can have all the brotherly bonding you want until you get sick of me."

Hisashi stared. "Are you serious?"

"That's how much I care about Izuku! He needs you!" Yoichi's eyes watered. "You got happy pictures from Izuku's birthday party, but you didn't see Izuku crying because none of his classmates showed up. He's being bullied because he's quirkless."

Hisashi paled. "I didn't know."

"Of course you didn't know, because you're never home. If you truly want to protect your son, then you need to be there for him." Insubstantial tears fell from Yoichi's face. "Please, big brother. Pick your family over your villainy for once in your life. If you'd been willing to do that for me, then everything could have been different. It's not too late for you and Izuku. Not yet. Right now, Izuku still wants you to come home. But if you keep neglecting him, then eventually he'll stop caring—just like how we stopped loving our parents. You have a limited window of time while your son loves you unconditionally. Make your choice."

Hisashi stood in silence, then slowly opened his mouth to give his answer.

When the doorbell rang, Izuku expected his mother had returned from grocery shopping. He ran to open the door for her.

Instead, his father stood in the doorway holding a suitcase. "Hello, Izuku."

"Dad!" Izuku cried, throwing his arms around his father's leg. This was the absolute best day ever. "How long can you stay? Will you at least be home for the weekend? If you're home for the weekend, then you can go to the new All Might theme park with me and Mom."

Hisashi knelt down and returned the hug. "Actually, I got a job transfer back to Japan. I'm home to stay." His smile was awkward, and he seemed to be addressing a point above Izuku's head.

Izuku hugged his father tighter and sobbed for joy.

OMAKE TIME!

Omake: The Joy Wears Off

Hisashi: I'm here to spend more time with my child! I'll make certain he has a nice, long childhood where nothing bad ever happens to him. There will be trackers on his clothing and cameras in his room.

Izuku: YOU KNOW WHAT HE'S LIKE, UNCLE YOICHI! WHY WOULD YOU DO THIS TO ME?

Yoichi: Sorry, I blame nostalgia.

#

Omake: Or the Happier Family Ending

Izuku: Dad, why do you keep talking to yourself?

Hisashi: Oh, no! He's onto us!

Yoichi: You could let Izuku borrow your quirk so that I can talk to my nephew sometimes.

Hisashi: I most certainly could not.

Yoichi: I know a song that gets on everybody's nerve…

Hisashi: I'm absolutely done with giving quirks to family members, but I'll have the doctor build a device that lets people talk to ghosts.

Later:

Izuku: It's great to meet you, Uncle Yoichi, but I really wish I could have gotten seeing ghosts as a quirk. According to my teacher, absolutely none of my abilities count unless it's a quirk.

Yoichi: Total nonsense, but I could be your quirk if you want.

Izuku: What does that mean?

Yoichi: I'll show you.

Later:

Izuku: Kacchan! I've got a quirk now!

Katsuki: What absolute nonsense—hey why is my sandwich rotting away?

Yoichi: Muhahaha!

Much later:

Izuku: All Might, can I become a hero if I don't have a quirk but I do have a vengeful ghost stuffed to the brim with pettiness and spite?

All Might: …Young boy, can you repeat that question again?

Yoichi: Pssst! Eighth! Give my nephew my old quirk or I'll follow you around playing bagpipes.
