My Avatar is the Heroine

"What kind of content is it?" Sero immediately raised his hand to ask.

"Rescue drills for various emergencies like natural disasters and floods." Shota Aizawa said, pressing the remote in his hand, causing devices with costumes to extend from the wall beside him.

"You can choose your costumes based on your own judgment this time. Some should be for specific activities. Pick one, put it on, and follow me to the bus."

"Yes!" Everyone stood up, ready to begin the lesson.

Ten minutes later...

"Huh, Su Lin-chan, are you really going to wear such a thick mask?"

Seeing Su Lin standing there in a black coat, Torhu Hagakure asked in confusion.

"Can't help it. Sometimes blocking things off avoids trouble."

If he remembered correctly, this lesson would most likely encounter an attack from the Villain Alliance. For someone who could change his appearance, proper concealment made it harder for enemies to figure out his true identity.

Anyway, the school hadn't recorded the appearance of his clone, so standing out like this, few would know it was Su Lin.

As the two spoke, Tenya Iida nearby blew the whistle in his hand.

Chirp chirp~

"Class 1-A, assemble! To board in an orderly fashion, please line up in two rows by number."

Torhu Hagakure said helplessly, "Even though Su Lin is the class rep, it's Iida-kun who's going all out."

"So he's more suited to be class rep than I am." Su Lin nodded in agreement.

If possible, he'd find a chance to pass the position to him next time, since Iida-kun was so serious.

Soon, on the bus.

Two rows sat facing each other. Izuku had Tsuyu Asui on his left and Su Lin on his right. Even just sitting there, he looked extremely nervous.

"I tend to say whatever comes to mind, Midoriya-chan." Suddenly, Tsuyu Asui turned to look at him.

"What!? Tsu... Tsuyu-san." Izuku Midoriya was startled, not expecting her to suddenly speak to him.

"Call me Tsuyu-chan." Tsuyu Asui emphasized.

"Uh... yes." Izuku blushed and nodded.

"I noticed... your Quirk is a lot like All Might's." Tsuyu Asui said seriously.

"What, ah, this..." Hearing that, Izuku Midoriya's expression froze instantly. He wanted to deny it but couldn't bring himself to say it.

So it was noticed just like that?

"But All Might doesn't get hurt, you know." Eijiro Kirishima said with a grin.

"Yeah, that's true." Izuku breathed a quiet sigh of relief.

"Still, that kind of straightforward enhancement Quirk is great. You can pull off all sorts of flashy stuff. My Hardening is strong against people, but it looks way too plain." Kirishima extended his arm, which had hardened into a material comparable to steel.

"No, no, I think it's really cool. It's a Quirk with a wide range of uses among Pro Heroes." Izuku praised sincerely.

"Pro Heroes, huh..." Kirishima suddenly fell silent, his gaze landing on Su Lin, who sat silently in his mask.

At this moment, he wasn't using Yukino's appearance, or else a girl's skirt and black-stockinged thighs would have been visible under the coat.

It was clear that the battle back then had left some psychological shadow on Kirishima-kun. Though his personality was sunny and passionate, seeing Su Lin still put considerable pressure on him.

"Don't overthink it." Su Lin thought for a moment, then explained, "My ability has limits. You can assume that stronger clones have shorter durations. The Mysterious Heroine X who beat Kirishima-kun last time was my strongest, but she can only last a few minutes a day. The other clones... wouldn't stand a chance against you."

"So what about that long black-haired girl? How many minutes can she last?" Mineta leaned in to ask.

"Eight hours... but what's it to you?" Su Lin shot Mineta a cold glance.

"Don't be so stingy." Mineta blushed and muttered, "Eight hours, can you change into her again and let me see? Those thighs are so sexy."

"Sexy my ass." Su Lin didn't hesitate to kick him.

If anyone in the class was least suited to be a hero, Bakugo ranked first, and Mineta was definitely second. You couldn't expect heroes to suddenly get distracted and start groping girls while saving people. But for this short guy with nothing but pervy thoughts on his mind, it was entirely possible.

So Mineta should just drop out already.

"Phew, speaking of which." Su Lin suddenly remembered something and asked quietly, "Can everyone keep my Quirk a secret for me from now on?"

"What's wrong, Su Lin-chan suddenly getting shy?" Tsuyu Asui asked in confusion.

Damn, Tsuyu, do you have to be so blunt?

Su Lin coughed. "Anyway, I'm counting on you all."

"Sure, sure. Just don't be embarrassed in front of us. And Su Lin, I think you've got it backwards—you're a girl yourself, but you always try to act like a guy. Look, Jiro looks so manly and she doesn't... pfft, Jiro, I'm sorry, aaaaah!" Denki Kaminari was in agony as Kyoka Jiro twisted his ear and smacked his forehead with her earphone jack.

Su Lin didn't want to say anything more.

After the bus drove for over ten minutes, everyone arrived at their destination.

"Students, I've been waiting for you."

At the scene, a figure wrapped in a full spacesuit appeared before them. Her voice carried a faint mechanical tone, somewhat feminine. But through the outer shell alone, her true appearance was impossible to discern.

"Ah, that's the space hero 13, a hero who shines brightly in disaster rescue scenes." Izuku Midoriya shouted excitedly.

"Wow, I really like 13, you know." Ochaco Uraraka nodded, happy as a child.

The massive venue before them—the USJ—was built by 13, a training ground combining all types of disasters: floods, landslides, fires, storms, and more. Its name: the Disaster Simulation Field.

Chapter 18: The Villain Alliance Strikes

Arriving on site, Su Lin had to admit this building was truly enormous. Standing inside felt like being outdoors; he couldn't imagine how much time and money had been spent just on construction.

"Before we begin, I want to remind you of two things..." 13 raised five fingers. "As you all know, my Quirk is Black Hole—I can suck in and crush anything."

"That's why this Quirk allows you to perform rescues in any disaster, right?" Midoriya asked expectantly.

"Yes, but this power can also easily kill people."

"Huh?" Everyone's expressions shifted.

"I think some of you have similar Quirks. In this superhuman society, Quirk use is strictly controlled through a licensing system, but... we all possess such extreme abilities. One wrong step, and we could easily kill someone. Through Mr. Aizawa's physical tests, you've already seen the potential of your own power. Through All Might's combat training, you've truly felt how dangerous your strength can be when used against others."

"In this lesson, I want you to change your mindset and learn how to use your Quirks to save others. Your power doesn't exist to harm—it exists to rescue."

After saying this, 13 bowed to everyone.

"That's all. Thank you for listening."

Applause immediately erupted.

"Su Lin, you seem distracted."

While everyone was fired up, Ochaco Uraraka noticed Su Lin staring at the ceiling.

"..."

"Another quest, huh?" He was actually paying attention to the system screen that had suddenly popped up.

code
[Side Quest: Repel Tomura Shigaraki's current attack.]
[Reward: Random Avatar Unlock Quest.]

Two simple, blunt lines.

"Another avatar reward. At this rate, won't I be able to maintain my avatar form 24/7?" Su Lin felt a bit conflicted.

The avatar was genuinely female, with all the corresponding physiological traits. Strictly speaking, Su Lin could even have the avatar bear children if he wanted—it actually had that function.

Whenever he could blush at himself, Su Lin couldn't help wondering if he had split personalities.

While he was thinking about this, Shota Aizawa standing nearby reached out a hand: "Alright, first—"

Zzzzt~

Suddenly, an electric current flashed across the hall's exterior. The central fountain twisted a few times, then slowly revealed a mass of purple-black mist.

A bizarre figure slowly poked its head out from the mist.

Aizawa's expression shifted slightly, and he quickly called out to everyone: "Gather together. Don't move. 13, protect the students!"

"What is that?"

The students had already noticed the scene at the fountain plaza.

"Is this like the entrance exam again—a surprise start without warning?" Eijiro Kirishima tried to get closer for a look.

"Don't move!" Aizawa barked again, quickly putting on his combat goggles. "Those... are villains."

"What?"

Staring at the ever-increasing number of figures radiating evil auras, everyone's expressions turned to shock.

"Villains?"

"Tomura Shigaraki."

Su Lin recognized that person.

The young man standing in the center, with a hand crawling over his face—he was the leader of this attack.

Su Lin had no intention of killing him. After all, he needed this guy to get in touch with All For One. On the other hand, he really wasn't confident in his own strength.

Because the system kept reminding him that he was currently at Spirit Core Stage One.

What exactly Spirit Core Stage One meant, he had no idea.

"The system says X-Hair is just an ordinary Servant right now, needing Spiritron Dress to gradually return to her original power. If that's the case, her performance should be similar to the Servants in the Holy Grail War... no, maybe stronger. X-Hair is a gag character, after all."

As the enemies just entered the venue, Su Lin immediately activated his Quirk, slowly transforming himself into Yukino.

Watching the number of figures below grow larger, the students' expressions grew increasingly uneasy.

"Villains... why are villains here?"

"These guys actually infiltrated a hero school? That's way too stupid, right?"

"Teacher, what about the sensors that detect intruders?" Momo Yaoyorozu quickly asked 13.

"Of course there are," 13 replied honestly.

Shoto Todoroki still wore that cold expression, but a hint of gravity crept into his brow. "I wonder if they've only appeared here, or across the whole school. Either way, since the sensors didn't react, that means someone among them must have a Quirk suited for this, right? They picked this isolated space far from the dorms, and knew the time our class would be here for training. As far-fetched as it sounds, they're not stupid—this is a carefully planned surprise attack for some purpose."

Su Lin naturally knew why they had come. Taking a deep breath, she spoke up. "They're here to kill All Might."

Hearing that clear, pleasant female voice, everyone's gaze fell on Su Lin.

"Kill All Might?"

"You've got to be kidding, All Might's that strong?" Izuku Midoriya couldn't believe it.

"That's the only possibility. Knowing the defenses here and still daring to come, they at least have the confidence to face All Might."

Shota Aizawa turned his head at that moment and called out to the space hero. "13, start the evacuation and try to contact the school. Those villains managed to disable the sensors, so there's probably a radio-wave-type Quirk causing trouble. Denki Kaminari, you try using your Quirk to make contact too."

"Got it." Denki Kaminari immediately set to work.

"Teacher." Sensing something was wrong, a worried Izuku stepped forward. "Are you planning to fight alone? With that many, even if you erase more Quirks, it won't be enough. Eraser Head's fighting style is to erase Quirks and then capture—you're not good at direct combat."

Shota Aizawa tilted his head slightly. "Having only one trick won't make you a hero."

With that, Aizawa leaped forward, charging alone toward the enemy.

Chapter 19: Tomura Shigaraki's Attack

"Here they come, here they come. Shooting Squad, get ready to fight!" Among the mass of villains, a man with all ten fingers shaped like gun barrels flashed a cold smirk, as if looking at a fool.

The woman behind him asked in disbelief, "Didn't the intel say it was only 13 and All Might? Who's that?"

"Who knows? But anyone dumb enough to charge straight in from the front is a complete idiot. Everyone, get him!"

In an instant, at least a dozen people launched attacks at Shota Aizawa.

But then...

A red light flashed.
