Idea 28.

I'm open to people suggesting things like ships but remember I write Fem!Izuku (Izumi) x other girls and I'm more interested in some pairs than others. Rare pairs are very welcome, you all know me.

Relationships such as potential friends, mentors, or family members (adoption is fine)

Miscellaneous stuff like what school Izumi may attend or if she didn't, whether she's a hero student, criminal, or villain, key parts of her personality, hero and quirk names and story titles, what type of story it is, hell you can all even suggest where OFA goes, etc.

Instead of just putting out ideas, I also did a little writing for each one but that DOESN'T mean this beta writing would be in the story if said idea takes off.

Anyways, feel free to leave suggestions in the reviews and of course which idea they pertain to.

Enjoy, more notes at the end!

Title: (?)

*Tsuyu POV*

"Soooo," Mina jumped up from her seat on the lounge couch as Izuku entered, "who was that you were on the phone with Midori?" the pink girl questioned slyly, drawing the attention of the other present students.

"Ah, please Ashido-san!" the green haired boy fretted, "it's not like that I promise!" he exclaimed, denying her implication. "I was just asking for advice on how to better look out for Eri," he nervously explained but the energetic girl wasn't going to give up so easily.

"Oh really?" Mina wondered teasingly, "from a pretty sounding girl though?" she revealed and their classmates all tunneled in on Izuku, a few of the boys making betrayed sounds, while a some of the girls tuned in more.

Izuku looked a bit overwhelmed, more so than usual, and his face was a bit red from the call out but he didn't seem upset at all. Tsuyu wasn't sure who the boy had called, she doubted it was like what Mina was saying, but she was at least certain that it wasn't someone that any of them, save maybe Bakugo, knew.

"See, I got you!" the horned student cheered, "look how nervous it's made you!"

"I'm sure it's not like that Mina!" Ochako defended, trying to help their friend while also keeping herself calm.

"Exactly, give Midoriya a chance to explain," Momo interjected calmly while signaling to Izuku to continue.

"Well," the green haired boy started softly, "you see..." he quieted even more, like he was carefully mulling over his words, "my sister is coming back to Japan."

The reveal had stunned the class for a moment, Tsuyu noting that even Bakugo was now giving his attention, and the freckled boy smiled sheepishly with a small laugh. Todoroki and Iida stared at the green haired boy curiously, likely both due to them have one or multiple siblings respectively, while the other students finally jumped at the news.

"What! I didn't know you had any siblings Deku!" Ochako's voice rose first, the others audibly agreeing to her words.

"I'm surprised as well, it's never come up before," Iida followed up as he adjusted his glasses and a few others threw their thoughts in.

"Is she hot?"

"What does she do?"

"Have you been holding out on us?"

Izuku put his hands up with a weak grin from the verbal onslaught, "My sister is 10 years older than me and she's been working as a hero overseas," he informed them, "I don't get to see her in person a lot but she does her best to call when she isn't busy."

After Izuku announced that she was coming back to Japan, Tsuyu had figured that she was the older sibling but not by an entire decade. Alongside that, the green haired boy had never brought up that he had a sibling, that was a hero no less, and the frog girl briefly wondered if distance was the only thing between them.

"She's a hero? Ooh can we see!" Tooru and Mina begged simultaneously and Izuku was already on it.

"Sure," he agreed readily, typing away at his phone, "she doesn't make the news a lot because she's more the underground type but there are a couple pictures of her on the job," he explained before showing his phone as the students crowded around.

"Woah, she looks cool," Kyouka surprisingly commented first and the others were all on the same page as they took in the somewhat limited photo.

You couldn't see much of Izuku's sister, it was more of an upper portrait type shot, but it was noted that her hair was the same shade as her younger brother's though her eyes were a bit sharper than his. Her hair was held up in a high ponytail and it was a mix of curly and wavy the same as Izuku's but her lower face was obscured by a large dark scarf. She was wearing an open, black, leather biker vest and her chest was bound while some kind of tattoo lined along the left of her chest, shoulder, and arm. Overall, she looked much more intense than her younger brother.

"How come you didn't bring her up before?" Kaminari voiced out loud, "she looks totally wicked!"

"It's mainly because she likes to keep to herself," Izuku reasoned again but Tsuyu decided to add in her two cents.

"But why do you seem so nervous about your sister coming back?" she questioned honestly even if it was putting her fellow greenette on the spot.

"Er, apparently there's a chance she'll make a few appearances at U.A," he told them truthfully, "she is an alumni," he added on, surprising them again.

Before anyone else could comment or ask another question, the explosive blonde who had been sitting away from them stomped to his feet and stormed off without a word.

"What's Bakugo's deal?" Mina asked first and Izuku scratched at the back of his head.

"Maybe he remembers better than me but our moms have said he's a bit nervous around her," the green haired boy relayed and the pink girl got a bit of a glint in her eye.

"Is it what I think it is?!" she beamed loudly but Izuku shot down her jumped conclusion.

"No, no!" he assured, "you know how little kids mess around with their quirks sometimes right?" he brought up, the others nodding at his words, "well she apparently scared him pretty badly when we were little after he accidentally hurt me with a little explosion," he told, "ah, I heard she only yelled though!" he hastily added, not wanting to make her seem mean probably.

"Yeah, angry older sibling sounds pretty scary," Kirishima noted with a wince at the thought.

"Aww," Mina pouted but redirected back, "Anyway, is she super strong?"

"She's the strongest hero I can think of!" Izuku suddenly exclaimed in a somewhat stunning outburst, "ah sorry about raising my voice," he apologized quickly when he noticed how some of them balked from being startled.

"I think I'm more surprised that you'd say she's the strongest hero," Todoroki's voice finally joined in after the claim, "you are All Might's biggest fan," he brought up in reminder, gauging how the green haired boy would react.

"Maybe that's true and I might be a little biased," Izuku bashfully admitted, "but honestly I can't see how All Might would fight my sister thanks to her quirk," he claimed, suddenly dropping a bombshell on all of them.

"What kind of crazy quirk does she have to compete with All Might?" Mineta yelled out, vocalizing their collective wonder.

"She's mochi," Izuku said both seriously and excitedly and as quickly as he had riled them up he had also instantly brought them back down.

"What?"

"Excuse me?"

"Did I hear that right?"

"My sister's quirk lets her turn her body into, control, and produce, mochi," he told them clearly, not joking in the slightest, and the class all looked at one another and then back to the green haired boy.

"Huh?"

Notes and Stuff

Quirk: Mochi

Hero Name: (?)

It's One Piece related again, who'd have thought?

Since this is just a test writing it's liable to change but since my brain said use Katakuri as a reference then I went with the idea of keeping Izuku in and having him have an older sister since Katakuri is extremely protective of his family. At least with this premise of keeping Izuku in, and this was suggested to me by an active reader, his older sister could instead by named Miku as Izuku's original name was Mikumo Akatani. Of course I could always just use Izumi but the option of a name change is there.

I wasn't sure what I'd do with some parts since observation and armament haki are heavily a part of Katakuri's skill set but I mean hardening the mochi naturally might not be too crazy and predicting things ahead is an achievable skill just not as great as future sight.

I'm not sure of a pairing just yet and honestly I haven't had ones that seriously clicked with this one. I guess if I have her as an overseas hero then I could try something with Star and Stripe but I'm completely undecided at the moment.

Anyways, feel free to leave me suggestions in the reviews!
