The sports festival was exciting, but it came and passed.

Hibiki decided to internship a girl named Setsuna Tokage as her quirk is sorta similar to her own. She's a student of class 1B. Her quirk is called Lizard Tail Splitter. Her quirk enables her to split her body into different parts.

Hibiki decided to have Setsuna take one of the guest rooms at her penthouse.

"Wow, you have a big place," Setsuna voices, looking around the large penthouse in awe. "You live here all by yourself? Seems a little over the top."

"It comes with my hero agency," Echo shrugs. "May as well take it."

"I was really surprised when you chose me for this internship," she admits. "I barely made it to the second round..."

"Your quirk is very similar to my own. Why you ranked so low is exactly why I wanted to internship you. You'll be a great hero one day, but you need proper training or you won't be. Go get yourself settled in your room, then we'll go and get some food. 'Kay?"

"Okay," she nods, taking her luggage into her room for the week. She returns about 15 minutes later. "Sorry, I got kinda lost."

"I'll give you a tour later. Let's go eat." Echo picks up her keys, leaving and locking the door behind them.

"Where we going to eat?" Setsuna asks.

"I'm gonna make us something," Echo answers. "You have any allergies or preferences?"

"No, I'm probably good with whatever you give me."

"Alrighty."

They walk a couple blocks and up an apartment building.

"Uh, what are we doing at an apartment building?" Setsuna asks confused.

"Taking care of someone." Echo pulls out the key for the apartment in front of her.

"Then shouldn't I be in my hero costume?"

Echo laughs. "Not that kind of taking care of." She opens the door and they walk in.

Setsuna continues to look around. "Wow, this place is really empty."

"That's what I thought too."

Taro comes around the corner at hearing Echo's voice. "Merow!"

Echo bends down to pet him. "You hungry? Let's get you some food." She moves over to pour cat food into two bowls, setting one down in the kitchen and taking the other into Aizawa's room. She heads back into the kitchen to the fridge and begins to pull out needed ingredients. "Setsuna, go ahead and make yourself comfortable on the couch and watch some tv if ya want."

She gives the number 6 hero a look of uncertainty before heading to the couch.

Echo releases her suit into her bracelets and gets to work on lunch.

Half an hour passes before the door to the apartment is opened by it's true owner.

Aizawa enters the apartment, immediately taking in the wonderful scent of food and the teenager sitting on his couch. "Uh..."

Setsuna immediately sees him and a shocked expression crosses her features. "Uh, Echo sensei?"

"Ah, it's okay! Aizawa, come in. I've just finished making lunch for us. You two come to the table to eat," Hibiki says.

Aizawa shuffles into his kitchen after taking off his shoes. "Why are you here? I'm able to take care of myself now."

"It hurts that you want me gone so bad."

"That's not what I meant."

"I know, just messing with you. Anyways, you may have your bandages off your face and your arms aren't broken anymore, but you still have your arms wrapped. I promised to take care of you until you're healthy," Hibiki says. "You need to be rewrapped again after lunch anyway and take more pain killers. You have to take them until they're gone as per Chiyo's orders."

"Yeah, yeah," Aizawa grunts and slinks down into his normal seat. He looks to the teen sitting across from him. "Who're you?"

"That's Setsuna of Class 1B," Hibiki speaks up, setting plates of food in front of the two. "I'm interning her for the week. Her quirk is a lot like my own."

"You must be the girl that can separate her body into different parts then," Aizawa assumes.

"Uh... yeah, that's me..."

"It'll do you good interning under Echo then," Aizawa says.

"Aww, I think that's the nicest thing you've said to me," Hibiki teases.

Aizawa rolls his eyes. "Let's just eat."

"Itadakimasu," they all say before digging into the food.

"MMm! Thish ish really good!" Setsuna voices through her full mouth.

"Don't talk with your mouth full, it's disgusting," Aizawa speaks up.

"Thank you, Setsuna," Hibiki smiles, glancing at Aizawa. "So, everything go well when you dropped your students off at the train station?"

"I have my concerns for Iida," Aizawa answers. "He got quite a few big offers, but he went for a small time hero in Hosu City."

"Where his brother was hurt..." Hibiki mumbles.

"I'm wondering if I should've let him go or not. Iida is a smart kid, but his impulses are not the greatest. I really hope he's not gonna do what I think he's going to do."

"Going after Stain," Setsuna mutters.

It's silent for a moment.

Hibiki sighs. "Well, Setsuna, I found where we're going to patrol. I have a hero agency building there that we can crash in." She turns to Aizawa. "I'll help watch over our student. I also assume you're going back to patrolling?"

"Obviously."

"Then take it easy and slow," Hibiki says. "I don't wanna come back to seeing you more injured."

"Yeah, yeah."

Setsuna looks back and forth between the two adults with a furrowed brow while stuffing her face with food.

A few minutes later, everyone has finished eating. Hibiki takes the dishes and rinses them out before getting the first aid kit.

"Alright, let's get your arms wrapped, and we'll be outta your hair," Hibiki says.

~~~

"Soooo, what's going on with you and Eraserhead?" Setsuna asks as they make it back to the penthouse.

Hibiki turns to her with a confused expression. "What do you mean? We work together? I've been taking care of him, since we live near each other."

"I felt some major flirting going on."

"Seriously? I didn't pick up on any of that," Hibiki thinks, bringing a hand to her chin in thought. "Anyway, we'll head to Hosu City tomorrow. We're gonna train a bit here. I have a really nice training room here. Holographic images and everything. So, answer me a question, how many parts can you currently split yourself into?"

"Uh, 50..."

"Great, we'll get it to a hundred by the end of the week!"

"A-A hundred?!" Setsuna gasps. "I... I don't think I can do that! Especially in a week!"

"You'll be fine. I know that you'll be able to do it," Hibiki reassures, placing a hand on her shoulder. "Now, let's head into the training room. Martial arts is always a good thing to learn, and hey, you'll be ahead of the class, lucky you."

...

By the time the two get on the train, it's gotten late at night. They're both dressed in their hero suits for late night training in Hosu. The two find Midoriya and his mentor on the train as well.

"Is that the number 6 hero?" "What is she doing here?" "Wonder if she'll let us get a picture with her?" "Or an autograph?!"

"Wow, sounds like someone is popular," Gran Torino says.

"The number 6 hero placement will do that..." Echo chuckles awkwardly. She then flinches, hearing something in the distance as Gran Torino and Midoriya chat.

"You okay?" Setsuna asks, noticing the flinch.

"Hey, did you see that?!" someone calls out in alarm. "That building exploded!"

"Passengers, please hold on to your seats." Then the train proceeds to slam on breaks, throwing everyone forward.

Echo looks off in the direction she hears something hurling in their direction and immediately stands up. "Get down!" She quickly sends out clones and shoves everyone away from the person crashing through the side of the train. Her clones manage to save everyone from getting injured, but they managed to get so injured they vanished.

Everyone begins to scream as the dust clears to reveal a pro who is then slammed to the ground by a giant greenish skinned arm. It's other arm tears back the train's metal to reveal itself to be a Nomu with four eyes.

"Nomu!" Midoriya and Echo shout.

"I want you to stay back! You hear me?!" Gran Torino tells Izuku before harshly kicking the Nomu back into the city.

"Gran Torino!" Midoriya shouts then goes after him.

"Midoriya!" Echo shouts, turning to Setsuna. She clones out Reassurance, Helpful, and Peaceful. "I'm gonna go out and help. This is Helpful, Peaceful, and Reassurance, they'll help you with everyone here. Help get these people calm and safely escorted off this metal death trap. You'll do great!" She turns, spreading out her suits wings and flies off into the city. She clones out about 50 of herself midflight, taking herself to go in Gran Torino's direction, sending the rest to the heat of the battle, and sending 3 in Midoriya's direction only for them to end up in the big battle as they couldn't keep up with Midoriya's speed.

She arrives right as the green Nomu is about to attack a couple that's standing in the street. She blasts the Nomu with a sonic scream at the same time Endeavor covers it in harsh flames. She lands beside Gran Torino.

"I was looking for the hero killer, but this thing will have to do," Endeavor proclaims. "Thanks, old timer. I'm afraid I don't know you, but I can take this from here on out."

"It's you!" Gran Torino gasps.

The couple speak a loud. "Whoa, look!" "Why are the number 2 and 6 in Hosu?"

Endeavor gives a little smirk with a smug huff. "Isn't it obvious? I came because I'm a hero."

"Pssh posh," Echo huffs. "You're here causing you're interning your son."

"Ah, the number 6 hero, Echo. Nice to see you here," he grumbles, slightly slumping in annoyance.

"Can't really say likewise. Was on the way here with my intern, where's yours?"

"He ran off, saying he needed to help his friend and to send pros to a certain location," Endeavor says. "An alleyway in four two ten, Echo Street in district four."

"Then I'll send some clones there," Echo says, making 3 clones, Crazy, Happy, and Smug, and sending them off.

The green Nomu screeches, getting back up and attacking the three of them. Echo clones out Sadistic and Insanity, no one is getting hurt because she held back this time, even if it's that shitty flame hero.

"That was only a low temperature warning shot, but still, it always KO's my opponent."

"Something's not right," Gran Torino speaks up then quickly moves when the Nomu bursts into flames.

"Your quirk is absorption and release, but you still took damage from my flame. Didn't you?" Endeavor grins. "Not a very impressive power."

"What's he doing?" Gran Torino thinks aloud, watching Nomu's body ripple. "Watch it, Todoroki! Echo! I think this guy's got multiple quirks!"

Echo quickly moves and surrounds the Nomu as it leaps in the air, sending a strong scream all at once and directing it straight for its brains. The echoed shrieks turn his brain into mush and the Nomu collapses on the ground.

"That is a Nomu, it's the same creature that All Might and I fought against at the USJ. They are no longer human, so you have to completely rid them of life," Echo tells the two pros. She flinches. "Todoroki, Midoriya, and Iida just took down the hero killer!"

Endeavor turns to her with a hint of shock and pride on his face. "Go, I'll finish off here."

The Echos and Gran Torino run off in the direction.

Midoriya, Iida, Shoto, Native, a few Echos, and a knocked out Hero Killer emerge from the alleyway they fought in.

"Ah! What are you doing here, boy?!" Gran Torino shouts, spotting them from across the street.

"Gran Torino!" Midoriya shouts as Gran Torino jumps into the air. "I was onl–"

Gran Torino cuts him off by kicking him in the face. "I thought I told you to stay on the bullet train!" He jumps back to the ground in front of them with puffs of steam coming out his ears.

"Who's this?" Shoto asks.

"Gran Torino, the hero I'm interning with..." Midoriya tiredly says. "I don't get it how'd you find us?"

"That would be because of me," Echo speaks up, making the clones that were with the group vanish and keeping Insanity and Sadistic out. "I can see from every clone I send out, meaning I can track them down."

"Well, I have no idea what's going on, but I'm glad you're not dead," Gran Torino sighs with his hands on his hips.

"Me too. I'm sorry," Midoriya tiredly replies.

Gran Torino clicks his tongue.

"Around the corner!" a feminine voice shouts out.

Everyone turns towards the shout, seeing a bunch of low ranked heroes heading towards them.

"They told us their was a request for help here, but it looks like you already handled it, Echo," a strange mummy wrapped looking dude says. "Children?"

"Those injuries look bad," another says. "I'll call an ambulance right away."

They all then pay attention to the Hero Killer Stain. Everyone gets to business, calling the police to come get Stain and making sure the children are alright. Iida moves to apologize to Midoriya and Shoto. All the Echo's that were in the big fight have vanished as they were no longer needed. The only remaining clones are the two with the real Echo and the ones with Setsuna.

"Everyone be on guard!" Echo shouts. "The winged Nomu is on the way!"

That's when it decides to make an appearance from around the corner, swooping down and grabbing Midoriya. This makes Stain awaken and immediately takes down the Nomu, rescuing Midoriya.

"Everything that I do," Stain growls out, completely killing the Nomu. "Is to create a stronger society."

Everyone freezes as Stain turns to them, any sudden movements and Stain could kill Midoriya.

"Did he just save that kid?" one of the small pros whispers.

"He took him hostage, idiot," another replies.

"He killed that guy with no hesitation."

"Everyone be on your guard! We've got a fight on our hands!" the female shouts.

"Why are all of you standing around like fools?" Endeavor speaks up, running into view as everyone turns to him. "The villain must've flown this way! Right?!" He stops and turns in the direction of Stain.

"You took care of the rest?" someone asks.

"Mostly, things got a little rough at the end," Endeavor responds as his eyes narrow at who he's looking at. "Hold on, don't tell me that man is–"

Midoriya is huffing and flailing in protest as Stain holds him down with a hand on his back. Stain's head slightly turns in Endeavor's direction and his eyes narrow. "Endeavor..." His mask slips off.

"Hero Killer!" Endeavor shouts, summoning a large fire in his left hand.

"Wait, Todoroki!" Gran Torino shouts.

"He has a student!" Echo shouts at him. "Can't your big fat head see that or do you need glasses?!"

Stain turns around with a gaze that makes everyone freeze in fright. Echo doesn't as she's seen way more creepier than his face. Her two clones seem to enjoy the sight.

"You false hero!" Stain growls. "I'll make this right! These streets... must run with the blood of hypocrites! Hero! I will reclaim that word!" He takes threating steps towards everyone. "Come on! Just try and stop me, you fakes!"

"I'd be glad to!" Insanity squeals. "Can I?"

Echo listens closely, hearing Stain's insides churn and knowing he'll fall on his own. "No." She crosses her arms, waiting any second for him to drop.

"There is only one man I'll let kill me! He is a true hero! All Might is worthy!" Stain shouts.

It's as if a dark pulse of energy radiates off of Stain that's pushed towards the group of heroes, making everyone flinch and pause in pure terror. Endeavor even takes a weary step back. The female small time pro falls to her butt.

The Hero Killer's blade is dropped and, like a switch, the heavy aura is gone, causing everyone to snap out of it. Stain is frozen in place as his lung is punctured with one of his ribs.

"I think... he's out cold," Endeavor voices.

Shoto and Iida fall to the ground beside the female pro, terror still on their faces. Gran Torino looks as if he's about to go too, but he remains standing.

Echo nods her head with her eyes closed as she makes her two craziest clone personalities vanish. "I heard it during his speech. His ribs were moving. One of the many broken ones managed to pierce his lung. He'll be out for quite a while."

"W-Were you... were you not terrified?" one of the average pros ask.

"Why would I be?" Echo answers. "If I released Insanity on him, he would be taken out quite easily. Even if he somehow managed to cut my clone, there would be no blood as it's only a clone. I can see him being trouble for everyone else though. Honestly, the Nomus scare me more."

"You're really brave, sensei," Iida says.

"Well, I am a hero. I would hope to be."

...

The police decided to have the story out that, Echo and Endeavor took down the Hero Killer.

Echo picked up Setsuna from the police station after everything was over. They immediately headed to sleep upon arriving at the apartment Echo has in Hosu.

"I'm sorry I just left you behind," Echo says. "We also got internship time cut."

"You're a hero, it's expected. I understand. Plus, you didn't truly leave me. I... was with your clones," Setsuna counters. "I also got to experience real evacuation drills. I was able to put my skills to the test."

Echo smiles. "And you did great, Lizardy."

Setsuna grins upon hearing her hero name. "Thanks."

"Now, lets get you up to 100 parts!"
