Homeroom was ten minutes long. Hibiki decided to skip out on the orientation to explore the school a bit more. She comes across All Might in his muscle form, peeking out from behind a wall. Her helmet is covering her head as usual.

She walks up straight behind him. "What are you doing?"

All Might releases a girlish squeal along with a small jump, quickly turning around. "Holy crap! You weren't kidding when you said you're undetectable."

She laughs at his startled face. "Sorry. You know... you're not really good at hiding. Also, I was curious as to what you're doing."

"Ah, I'm watching Aizawa's class. He's expelled over 150 students, so I'm kinda nervous he'll expel one of the students I know. He said whoever is in last he's going to expel."

"Wow, that's a lot." She doesn't question the expel part though, agreeing somewhat with the idea. If they're not worth it, they're not worth it. She blinks, deciding to peek around the corner and trying to determine which student he's referring to.

He follows her, towering over her as he does. She watches a fluffy green haired boy doing a ball throw test. All Might releases a surprised and proud cheer as the ball soars across the sky.

An ash blond boy suddenly blows up and rushes towards the green haired boy. "Deku you bastard! Tell me how you did that or you're dead!"

Aizawa sends out his scarf and catches the ash boy before reaching the other boy.

Hibiki smiles with a small giggle at the way the blond looks so shocked. All Might gives her a strange look but with his signature smile still on his face. The pair watch as they do many other tests which starts to cut in on Hibiki's class time. She doesn't mind though. She didn't have much planned for today. At the end, the green haired boy ends up in last. All Might sucks in a scared breath and releases it as Aizawa says he was kidding about the expulsion. He hands the boy a nurses note and heads in the two newest teacher's direction.

"Aizawa, that was a rotten move," All Might speaks up as Aizawa turns the corner.

Aizawa stops and tiredly looks in our direction. "All Might, Echo... so you were watching?" He turns away. "No talk shows today, All Might?"

"A rational deception. That's cute, but you're not exactly known for being lighthearted," All Might says. "I read your file. Last year you expelled an entire class of freshman students. You have no problem kicking students out anyone you deem unworthy. You were planning to send last place home." He points at Aizawa. "So that can only mean you see the same kind of potential in young Midoriya that I do."

"What is this about?" Aizawa turns to him with a grin. "It almost sounds like you've been in his corner the whole time." All Might flinches. "It's a little early playing favorites." He begins to walk off. "He doesn't have zero potential, I'll admit. If that were the case I would've sent him straight home after class without hesitation. It's cruel to let a kid keep dreaming for something that will never come true. Echo, I'm sorry I took away some of your class time."

"No problem!" Hibiki calls out, louder than planned. "I'll see you guys later." She walks around the corner where all the kids are still taking a breather. "Hellooo students!"

They all look in her direction.

The green haired boy from before suddenly squeals. "You're the number 6 hero, Echo! Your quirk is so cool! You can duplicate as well as use a sonic scream and use echolocation!"

Many other gasps of awe are mentioned.

Hibiki swears she heard something about her boobs, but she ignores it. Echo lets out a giggle. "Looks like we have a fanboy in our midst."

His face flushes in embarrassment. "S-Sorry..."

"It's alright. Everyone is a fanboy or girl in some way. You should go to Recovery Girl and get your finger healed up. You won't be missing anything all that important today."

"Okay!" he shouts and rushes off.

"Alright, it's a good thing Aizawa brought you all out here. I was thinking outside would be best. Anyway, whenever you have this class, come back to here. Martial arts will take a lot of room."

"Why do we even need martial arts if we have our quirks?" the blond scoffs.

Echo smiles. "Glad you asked. As you just witnessed yourself, your quirks can sometimes be canceled by another quirk. You need to know how to defend yourself."

"I agree," a tall boy with glasses says.

"I don't," blond boy says. "You should learn how to move along with your quirk."

Echo gets an idea. "Alright, how about this? I'll just show you how useful martial arts actually is. Everyone, I want you to fight me and you can use your quirks as much as you want."

They all released surprised gasps or exclamations.

"What?!"
"Is she serious?!"
"There's no way!"

"Also, I won't use my quirk and keep my eyes closed the whole time."

The boy grins, blowing a few explosions from his hands. "Sounds good to me."

"Good," Echo says, closing her eyes. "I'm ready. Begin."

~~~

Aizawa is making his way back to the office room, so he can sleep. He stops as he spots a large explosion from outside. He prepares himself to stop whatever is going on until he sees that Echo is involved. He stands, looking out the window with sudden interest as he notices she's not using her quirk.

"She's quite peculiar, isn't she?"

Aizawa flinches, turning to the voice next to him to see the school's principal. "Uh, yeah, I guess."

"I brought her here to show that they can't rely on their quirks for everything. I figured she would be a perfect fit for that role. You know, she didn't even try to become a popular hero. She's just that good."

"Is that so?" Aizawa says, mentally sighing already done with this conversation. He truly doesn't care.

"I have reason to believe that the two of you will get along well," Nezu says with a nod in thought. "You are friends with Mic and Midnight after all."

"Forcefully."

"But you allowed them. If you truly didn't want them around, you would've said so years ago. She's definitely not as... flamboyant as the two of them. She's more like you. That's enough for me to believe you'll get along. Hmm... a mix between you and Hizashi along with her own charm."

They continue to watch her as she takes every one of her students down. The last remaining student standing is the boy with the tail. They square off, talking to each other a bit after a few blows. Her helmet vanishes from view, letting her hair fall around her in waves.

"If you say so."

After a good while, the tail boy is eventually taken down.

"I know so."

The two stand there watching until the bell rings for the next class.

~~~

Echo quickly moves to the left as she hears footsteps, already figuring out that the person is a boy and has some kind of body hardening quirk. He'll be more difficult. Crackling comes to her left and she jumps up pushing herself off the explosion boy's shoulders, twirling out of the way of what sounds like a tongue trying to grab her. She ducks and grabs the tongue then begins spinning around, knocking the frog girl into anyone nearby. That quickly takes out the floating girl and the fancy blonde boy. Everyone else manages to dodge, some barely. The pain of being used to hit others also puts the frog girl out of it.

"Is this all you guys got? Come on!" Echo shouts with a grin.

She hears the sound of what sounds like tape moving towards her from her right. Another person is coming from her left. She flips backward which results in the tape wrapping up the invisible girl.

"Oops! Sorry!" tape boy calls out.

Echo smirks, now knowing his position and swiftly punches him in the stomach. She strikes hard enough to put him out but not enough to knock him out. She quickly ducks and sweeps another student off their feet, landing roughly on their butt with an oomph. Echo does a backward somersault which dodged an acid attack. She sweeps that girl off her feet onto the other person that she just tripped up. That lets off a surprised electric discharge from the boy that hit most everyone around them. Echo's suit protects her from the attack. The only remaining students, from what Echo can tell, are the bicolored boy, explosion boy, tail boy, skin harden boy, tentacle boy, and bird head.

"Alright boys, give me all you got."

Ice boy decides to send a sheet of ice to trap her. She jumps up, moving in just the right ways to land on top of the ice. Explosions ring off from below her. Listening to him getting closer along with the shadow demon from behind her. She bends her legs and slides down the ice like she's on a slide right as he sets off an explosion right in the shadow's face.

"Dammit!" explosion boy shouts.

Ice boy sends another blast of ice, trying to nab her while she's sliding. The nanotech in her suit sends out the suit's gliding wings and bounces her off the ice to let her fly right over. She lands and rolls automatically, hearing the harden boy aim a hardened fist straight down on her head. Echo swipes his feet from under him, grabs his legs, and slams him into the tentacle boy coming behind her. Tentacle falls to the ground with a groan.

"Alright, five to go."

Explosion boy once again makes his way towards her. She ducks left, grabs his arm, and judo flips him onto his back, grabs his leg, and throws him in the hardened boy's direction. He manages to save himself by blasting his hands out to steady himself. Ice boy sends another attack and she moves back to dodge and continues until she's beside the two before mentioned boys. The ice encases the hardened boy as he was a little dazed from being thrown. Explosion manages to dodge by firing himself above it.

"Watch yourself, icy boy!"

Tail boy makes his way over and begins to trade blows, but she dodges each one.

She smiles as she realizes who she's fighting. "Glad to see you made it into U.A."

"Huh?" he mutters confused.

She manages to turn him so her back is facing the other boys then turns and rushes straight into their direction. Bird boy sends out his black shadow as ice boy sends pillars of ice. Echo uses the pillars to hide behind and sneaks up behind bird boy, sending a strong chop to the back of his neck.

"Three to go."

Icy boy begins to get aggravated and Echo can feel it. He suddenly sends a giant wave of ice, one that she won't be able to dodge in time. She ends up frozen, unable to move, in the ice.

Icy boy breathes a sigh of relief. "Finally."

Her suit begins to melt the ice around her. "Never said I wouldn't use my suit."

"Die!"

Before ice can send another blast, explosion dashes forward to blast her straight in the face before she can get completely out of the ice. She takes it full force, once again her suit protecting her. The explosion busts the ice around her and blows up steam everywhere, giving her enough coverage to grab explosion's face and repeatedly smack it into the ground or ice. He passes out.

Down to the last two. Steam still covers the area, so she stealthily moves through it, not making any peep to her whereabouts. She can hear the cold heavy pants of the ice boy and moves towards him. He never sees her coming as she quickly takes him down with a pressure point in his neck. The steam clears.

"And one."

Mashirao looks around in amazement. "Whoa."

Echo runs up to Mashi and he turns just in time to dodge her.

"You got lucky, tailboy."

He jerks in surprise. "How could you tell?"

"I recognized your movements. I taught you them."

"What?"

She lets her helmet down to let him see her face. "Mashi-chan!"

"Hibi-senpai!" he shrieks.

She laughs. "Surprised?"

"I didn't know you were Echo?!"

"Guess I'm doing a good job at keeping my identity then."

She leaps forward and they begin to exchange blow after blow after blow. He was used to her movements and she was used to his. Echo could easily take her student down, but she wants to see how much better he's become. She's rather impressed he's keeping up with her. After a few more blows, she's decided she's seen enough and takes him out with a spinning hook kick.

"Owww..." he groans from the ground.

"I'm impressed, you've improved rather well."

Everyone else begins to come to as Echo pulls Mashi up with one hand.

"That sucked..." electric boy groans.

Echo leaves her helmet down, she trusts the kids won't do anything. She opens her eyes and claps a few times to gather their attention. "Alright, gather round and tell me everything that you did wrong."

The black haired girl with a high ponytail immediately answers. "We underestimated you and didn't work together as a team."

"Yes, but that's not all. You didn't look out for each other. I tricked many of you into hitting each other. All of you need to pay attention to your surroundings and tap into your other senses. Many of you have long-range attacks. Anyone who manages to get by that can easily take you down close range. That is why you need to learn close combat. Got it, explosion boy?"

"Yeah, yeah," he groans.

"Now, class is almost over. Anyone who is injured and wants to go to the nurse, go ahead. I tried to keep injuries to a minimum."

"You were holding back!" explosion shouts.

"Obviously, I wanted to see what you all got. Well, hear. If I wanted to quickly take you out, I would have after your first explosion for coverage. And, you know, I wasn't using my quirk, so there's that. I've decided. Every Saturday after school is over, we will do this again. That way I can continue to see how well you all are improving."

"Will you use your quirk?" floaty girl asks.

"Oh, you all won't deserve that until you take me down with all of you still standing," Echo replies.

"What?!" they all shout.

Echo smirks and the bell rings. "I'll see you all Thursday."

~~~

Sixth period draws to a close and Echo makes her way to the teacher's office. She doesn't teach a seventh or eighth period on Mondays. Technically, she's able to go home. She stays behind though, planning to nap on one of the many couches till the school day is over.

Mic is in the room, getting his things together to go teach English 1 for class 1-A. "I wouldn't take that couch."

"Why?" Echo asks.

"That's Shota's couch. If you're on it he will just sleep right on top of you. He doesn't care. We've set all kinds of things there to test it. Support items, paperwork, chairs, and even a table. He will sleep on top of it."

Echo blinks then giggles. "That's hilarious!"

"Right! I got pictures! I'll show them to you later. Gotta go teach these kids some English!" he walks out the room.

Echo takes a look at the couch before moving over to a different one and falling straight asleep.

~~~

The last bell of the day is what finally wakes Echo from her slumber. She stretches as she sits up, noticing a blanket drift off her body. She looks at it confused on how it got there. Who covered me with a blanket? She stands up to find Aizawa in the room. "Everyone already leave?"

"Yeah, that was the bell telling us to get out," Aizawa sighs, standing. "You have a good nap?"

"Yeah. Uh, thanks for the blanket." She folds the blanket and drapes it over the back of the couch.

"Hizashi did it."

"Oh, I'll have to thank him then." She notices the sleeping bag draped over Aizawa's shoulder. "A sleeping bag? That's a good idea actually. I'll have to bring mine."

Aizawa gives her a tired look. "Sleeping bag is my thing."

She laughs. "Last time I checked you weren't, The Sleeping Bag Hero: Eraserhead."

"Guess I gotta go get it changed then."

She laughs again. "Didn't think you had jokes, Aizawa. Don't worry my sleeping bag isn't yellow it's blue. We won't be totally matching."

"Blue? Figured you'd have green."

"Well blue and yellow make green," Echo says nonchalantly. Her eyes widen as she realizes what she just said as Aizawa gives her a surprised look. Her pale face immediately gets some rosy color to it. "Heh heh, that was way more sexual than I thought it to be... I-I was trying to be cheeky." She awkwardly rubs the back of her neck. "I guess I should go. Patrol starts soon. See ya tomorrow, Aizawa." She quickly leaves to the top of the school to glide all the way to the city.

Aizawa brings a hand to his chin. Cute.
