Finally got to write the USJ Arc! This is definitely one of my favorite Arc in the series. This is just the prelude though! The rest of the Arc will be concluded in the next chapter.

I have an announcement before you read! From this chapter onward, Ryouka will address the teachers as "sensei" only if she's talking to them directly. Also Thirteen will be referred with male pronounces from this chapter too because using the gender neutral ones confuse me sometimes. Sorry about that!

I literally hadn't checked this chapter for mistakes, so probably I made a lot of them, but I hope you enjoy this anyway!

Edit: I forgot the line break lol.

No. 6 Storm

"Ok, quiet down you brats. From today onwards we'll be joined by Ibuki here for Hero Studies. Any questions you want to ask her can be asked later. Preferably outside of class." Aizawa Shouta, the homeroom teacher for 1-A, grunted behind his—bandages? Scarf?—as he gestured towards Ryouka who was standing beside him in front of the class.

"Ibuki. Go sit on the empty seat beside Yaoyorozu."

Ryouka glanced at the class to see the girl he mentioned raising her hand with a smile at her and she nodded, approaching the girl.

"Now… for today's Foundational Hero Studies, it was decided you'll be supervised by a three instructors comprising me, All Might, and somebody else," the unkempt-looking teacher continued monotonously and a thin boy with straight hair raised his hand excitedly at his announcement.

"Sensei! What'll we be doing!?"

"Disaster, shipwrecks, and everything in between," he announced, pulling out a fancy card with the word RESCUE emblazoned on the surface. "It's rescue training."

"Rescue… looks like it'll be a lot of work this time, too."

"Right?"

The students began to chat excitedly, but Aizawa was quick to stop them before they got too rowdy.

"Don't get ahead of yourselves," he warned. "As I was saying, this time, it's entirely up to each of you whether or not you wear your costume. Some of your costumes probably aren't adapted to the task at hand, after all. The training area is fairly far away, so we'll get there by bus. That's all. Go get prepared."

As everyone excitedly claimed their costume cases and went to the changing room to change into their costumes, Ryouka approached the underground Hero.

"Aizawa-sensei," she called out, catching his attention. "All Might-sensei will not be joining us today."

She was informed that Aizawa knew of All Might's circumstances and also her role as her healer so she decided to inform him of this. Hearing her words, the man seemed to hold back a grimace, understanding her underlying message that their resident idiot had probably overexerted himself again.

"…That guy's the height of irrational." The man sighed. "Oh well. Thanks for informing me. Now go prepare yourself."

"Yes sir."

"Senpai, Senpai! You have a healing Quirk, right? How does it work exactly?" A pink haired girl asked excitedly, leaning forward and peeking at her from the seat beside hers. Ryouka paused for a moment there before she decided to explain. It might be good for them to know what her Quirk was like since they were probably going to injure themselves sooner or later.

"It's my breath," Ryouka said. "It converted my own energy into healing power—specifically it will reconstruct your body back to its prime state."

Yaoyorozu, seated across of her looked interested at this. "So your patients have to breathe in your breath to be healed?"

"Yes," Ryouka nodded at her. "Healing time depends on the injury itself, but I can heal almost anything—even reattaching severed limbs—as long as the wounds are fresh."

Everyone in the vicinity that was eavesdropping on them oohed at her explanation in awe.

"Isn't that, like, pretty amazing?" The blond boy with black strips on his hair said in amazement. "Even Recovery Girl can't do that much, right?"

"Yes. Chiyo-sensei can only speed up her patient's recovery rate," Ryouka nodded. "I have my limit though as my Quirk will eat up my energy. Heal too many people or too severe an injury, I'll pass out."

Everyone nodded in understanding at that.

"D-does that mean you have to k-kiss them?" The girl, Uraraka if she remembered correctly, asked with a bright pink blush on her cheeks. Ryouka smiled inwardly. What a pure girl.

Ryouka nodded at her as she played with her pendant again.

"That is the easiest method for me to heal people, true," she answered with slight amusement as the kids' faces which suddenly turned red too when her words finally registered on their virgin minds.

"A kiss…!" She heard the grape-looking midget whispered in reverence as he looked at her chest area with extreme interest and Ryouka narrowed her eyes in distaste. How vulgar.

The rest of the bus ride to their location was filled with various questions from the excitable children that composed almost the entirety of 1-A students. Ryouka was grilled thoroughly about the circumstances that landed her there and they provided their own info of their own accord in exchange for hers.

They were an excitable and friendly bunch. All Might was right. They were good kids.

When they were finally satisfied with her answers, they went to gossip about their own classmates. Coincidentally, that familiar green-haired boy she saw on her first day was a student of 1-A too and if she interpreted the subtle glances he was sending her correctly, it seemed that he recognized her too.

"…Well, if you're talking about flashy and strong, it's gotta be Todoroki and Bakugou right?!" the boisterous redhead that she remembered was named Kirishima said loudly and a blond boy with a sour face clicked his tongue in irritation.

Ryouka frowned.

Strangely, his face was also familiar to her. Where did she saw them before though?

"Bakugou's always mad, so he doesn't seem like he'll be popular though," quipped Asui, the adorable frog-like girl, causing the blond from before, Bakugou, to jump out of his seat yelling threats at her.

At his roars, Ryouka suddenly remembered.

Bakugou Katsuki.

Midoriya Izuku.

They were a year behind her in middle school.

She remembered that Bakugou was a terrible loudmouth who used to bully Midoriya, who was a small and skinny Quirkless kid who loved to make observations about Pro Heroes and mumble creepily in the hallways. He changed so much since she saw him last that she didn't recognize who he was.

She vividly remembered that one time that she spotted Midoriya behind the gym storage, nursing the burns that was inflicted on his arm by the loudmouth bully—burns that would have disfigured the green haired boy's arm for life if she didn't heal him so quickly.

That memory instantly made Ryouka hate the blond. She hated bullies.

But… this realization brought something to her attention.

Midoriya Izuku… you were supposed to be Quirkless.

"Quirkless?" Kirishima said suddenly.

Oh. Did she say that out loud?

"Oh, so I was right!" Midoriya exclaimed with a gasp. "You are that Ibuki-senpai, right?"

Ryouka eyed him for a moment before she nodded.

"If you mean your upperclassman from middle school, you are correct," Ryouka confirmed to the green haired boy who beamed at her.

"I knew it! I thought it was you, but you look so different than you were back then so I wasn't sure," Midoriya babbled sheepishly as he made strange gestures with his arms. "I always wanted to thank you for healing me, but you were so good at disappearing back then and no one could find you when you didn't want to be bothered, so I haven't got the chance to do it."

"It's fine, I don't mind," Ryouka nodded at him again to drop the subject.

"Wait wait wait!" the blond with the black stripe, Kaminari, suddenly exclaimed. "Midoriya, you were Quirkless?!"

Oh yeah. She was curious about this too.

"Oh… that's…" Midoriya stuttered nervously as he scratched the back of his head. "My Quirk manifested… really late? I got it just before the entrance exam, actually."

Kirishima gaped at his answer. "Seriously?! Man, talk about lucky!"

"Yeah, and your Quirk is so powerful too!" Uraraka chimed in with excitement.

Midoriya's classmates continued to grill him about his Quirk, and the boy gave half-hearted answers that he answered with a hint of panic and nervousness.

Ryouka's eyes narrowed.

"Your Quirk reminded me of All Might," she remembered Asui quipping about it earlier. It might have been a simple compliment as the boy was infamous for being an All Might otaku, but…

…Could it be?

Before Ryouka could continue on that train of thought though, the bus had stopped in front of a dome-like building that somehow resembled a famous theme park in Osaka. Everyone got off the bus quickly, chattering in excitement as Aizawa herded them inside the massive building where Ryouka's homeroom teacher, Thirteen, stood to welcome them.

"It's Space Hero, No. Thirteen! He's the gentlemanly Hero who has rescued tons of people from disasters!" Midoriya gushed, seemingly vibrating with excitement in his place.

"Let's go inside without delay!" Thirteen waved at them in greeting and gestured towards the building. Everyone cheered at this and followed the spacesuit-wearing teacher excitedly inside.

"Wow, it looks like USJ!"

"Shipwreck, landslide, fire, windstorm, et cetera—It's a training ground that I made with different types of accidents and disasters," Thirteen began, making a grand gesture towards the area he specified before he finished proudly, "It's called the Unforeseen Simulation Joint, or USJ for short!"

"It really is USJ..."

Ryouka's lips involuntarily quirked upwards at the faces of the students. Before Thirteen could say more though, Aizawa pulled him aside and whispered something to him.

"Thirteen. I have words from Ibuki that All Might can't come today," the rugged-looking teacher said with exasperation in his face as he put up 3 of his fingers. At his words, Thirteen laughed cheerily.

"That's so like him!" Thirteen giggled, covering the lower half of his mask with his hands like someone would do to their mouth when they're laughing. "But it's fine isn't it? We have back up plan in case something like this happen."

Aizawa let out a long sigh before he shook his head. "It can't be helped. Shall we begin?"

Thirteen nodded before he perked up, remembering something. "Ah, wait! Before we begin, let me say one thing. Er… or two. Or three."

Her homeroom teacher continued to talk, addressing the first years. Ryouka wasn't paying attention to it though. Instead, she opted to observe her surroundings.

Like what her homeroom teacher said before, the dome-like building was divided into several areas all having different types of accident and disaster simulation. Everything was incredibly detailed and real and Ryouka was once again left amazed. She have lived a lot of lives in a lot of different and strange worlds, but this was the first time she ever saw something like this. For everything to be completely man-made with no magic involved was just incredible.

She continued to look around, humming slightly in appreciation when she saw something crackled to existence in front of the fountain at the plaza just below the stairs.

What in the world…

"…this class is a fresh start. You shall learn how to use your Quirks to save people's lives. You do not have powers so you can harm others. I hope you leave here with the understanding that you have powers in order to help others."

She faintly heard the words spacesuit-wearing Hero said in the background, but she couldn't discern it what with her attention stolen by that thing that grew wider and wider by the second and looked vaguely like a… portal…

In that very instant, chill ran down her spine.

"Aizawa-sensei!"

She shouted loudly, calling everyone to attention just as the lamps around the building suddenly turned off on their own. The scraggly teacher turned around quickly and saw what she was seeing. Realizing what was happening right under their noses, he immediately dropped to a defensive stance and barked orders at his students.

"Gather together and don't move!" Aizawa ordered, his voice tense. "Thirteen, protect the students."

That portal-looking thing in front of the fountain expanded far and wide like a black mist. One by one, people Ryouka had never seen started trickling out of it, all of them wore identical cruel grin that stretched wide on their faces.

Ryouka narrowed her eyes at the sight, realizing what they were as Thirteen turned around to see what had made them so on edge so suddenly.

"What's that?" Kirishima asked, leaning closer to the edge of the stairs. "Is this like the entrance exam where the lesson's already started?"

"Don't move!" Aizawa shouted at him. "Those are villains."

Ryouka heard the most of the students gasped in disbelieve, distress etched in their innocent young faces. In front of the fountain, a gaunt man with many fake-hands attached on his person stepped out of the mist with a large creature following closely behind him.

Aizawa clicked his tongue in irritation.

"The trespassing the other day was the work of these scumbags after all, huh?" he muttered as they watched the Villains creeping closer to the edge of the stairs. Thirteen nodded, agreeing with him. At Aizawa's words, Ryouka suddenly remembered the incident during lunch time several days ago.

'So that was them', she thought, realization coming on to her.

If they were the one who trespassed the other day, it meant that they've been planning for this attack for days, at the very least. They must have some kind of objective that they're confident they can accomplish—otherwise they won't be so arrogant as to invade the nest of some of the best Pro Heroes to ever exist.

"Sensei, what about the trespasser sensors?" Yaoyorozu asked, looking worried as she stepped closer to the teacher.

Thirteen shook his helmet at her. "We have them, of course, but…"

"Did they only appear here or around the whole school?" a deep but boyish voice said suddenly. Ryouka turned and saw it was the boy with half-red half-white hair and a tacky costume—she forgot his name—who was the one speaking.

"An isolated area separated from the main campus during a time when a class is supposed to be held here," the boy continued. "They might be fools, but they're not dumb. This surprise attack was carefully planned with some sort of goal in mind."

Yeah, that was what Ryouka thought too! Tacky though his costume might be, this boy was smart.

Ryouka was about to suggest they evacuate from the building while they still can when suddenly a black void appeared on the floor beneath her feet. Before she could voice her surprise, a hand came out from inside the void and enclosed itself around her ankle.

No fricking way. Are you even serious right now.

Ryouka yelped as the hand suddenly pulled her under in an alarmingly fast pace and tried to kick the hand off her, but the hand stubbornly held on. Sinking further into the void, Ryouka urgently stretched out her hand to Aizawa whose eyes had widened when he realized what was happening to her.

"Sensei—!"

"Ibuki—"

Aizawa dashed towards her in an instant and tried grab her outstretched hand, but just as his fingers grazed hers, it was too late already.

She had been completely swallowed by the void.
