"Alright, young heroes, Training is over for the day." All might announce facing the twenty-six students. There were a few grumbles coming from some of them as they wanted to see what the new students were capable of, but they obeyed nonetheless. Without warning, the lights went off, causing an uproar among the students.

"Hey! Who turned off the lights?" Kaminari complained instinctively as he clutched on to the nearest person, who turned out to be Bakugo. He didn't even have time to apologize, as he received a mini-explosion on his face.

"What's going on?" Mineta cried, shaking in fear.

"Stay calm, everyone." Aizawa spoke calmly as Yaoyorozu created torch lights, and Todoroki lit up his left hand with flames, bringing a source of light. "Something should be wrong with the power. Iida, I want you to lead the rest of the class back to the classroom. Got it?"

"The power loader must be working on something." Hatsume stated.

"I don't think Power Loader did that. Now that you mention it, this has happened before."

"Yeah, I did it once, though, when working on one of my babies."

"That was you?!"

Iida sighed. "I'm sure you heard Mr.Aizawa. Follow me and Todoroki as we lead the way." Needless to say, half of the class was not listening. "Are you guys even listening?"

*Creak*

Everyone in the gym stiffened at the sound. Soon, the class began panicking before Aizawa told them to shut up. He was skeptical since it could either be a teacher, the principal, a student, or any random person. The power of the school can't just go out without warning.

"Todoroki, I need you to stay near Tokoyami." Aizawa instructed while the boy obeyed. "I need you all to leave this instant, Ectoplasm."

"Yeah."

"I'll tag along too." Cementoss stated. The class was a fair distance away from the teachers.

Tanjirou's nose twitched a little. 'Demons' was the word that resonated in his mind. He looked at his friends with grave expressions. There was a demon here. Inosuke was oddly quiet, trying to detect the presence of the demon, while Zenitsu listened in for any cruel sound.

A loud crash was heard the next second, making everyone look in the direction where the sound came from. The figures slowly came into view, appearing as morphed demons or humanized ones.

"What the heck is that?" Mina cowered back in disgust. The teachers got into a defensive stance, including the future heroes.

"Damn Villains!" Bakugo yelled about activating his quirk until his teacher put a hand out. "No, you kids should go." The blonde did a double take.

"What?"

"I didn't stutter. Leave and go get the rest of the staff." Bakugo was slightly annoyed but heeded his teacher. Iida, known as the fastest, rushed to get anyone to help.

The rest of the students watched as their teachers battled with the students.

Cementoss quickly made a wall, but the demons broke through. Ectoplasm created many clones, but they were taken out in a few seconds.

"What the heck?" Ectoplasm muttered in a breath. "Aizawa, they are breaking through." Cementoss yelled to the black-haired man. "Some strength enhancement quirk, perhaps."

Aizawa nodded, grabbing his binding cloth and activating his quirk. He wrapped it around those who were pounding against the cement, tying them in place, before landing a punch on one.

"He got him!" Kirishima said. Much to Aizawa's surprise, the demon was not even fazed. It landed on his own, with the pro-hero dodging just in time. He looked at the floor, noticing the damage it had just caused.

'What?'

"No way." Midoriya mumbled. "Mr. Aizawa's erasure quirk didn't work."

"But... how come?" Uraraka asked in shock. Watching their teachers battle the so-called villains. Aizawa frowned. ' My erasure quirk couldn't nullify it. So they must be the demons those kids are talking about.'. He broke out of his train of thought when a huge piece of debris was thrown at him. He dodged, not entirely earning a scratch on his hand.

The rest of the students watched from the sidelines, hoping that they would somehow win as things were not looking good for them.

"Not doing anything ain't my style." Bakugo yelled, exploding his way to the enemy.

"Wait Bakugo!" Kirishima yelled, running to his friend. Bakugo raised his right palm, facing the demons, before yelling at them to die. He released his explosions, causing a huge wind. The demons practically didn't dodge, sustaining wounds.

"Take that!" Bakugo smirked at his offense to the intruders. His celebration was cut short as they were still standing and regenerating.

"What the fuck?!" He cursed. He fired more shots, hoping for them to keep their distance as they got closer. Kisirhima attacked one that was coming towards his friend's blind spot. "Need a hand?"

"Shut up." The demons had gained the upper hand as they increased tremendously, cornering the teachers. All might have followed young Iida, knowing that the kids are capable of protecting themselves for a short time. Right now, he has to get help.

"What are we waiting for? Let's slay these demons." Inosuke fumed at his friends whisperingly.

"Hold on. We cannot risk exposing ourselves. Zenitsu pulled him back. As soon as he said that, he instinctively pulled Mineta away from where a demon was about to land.

"A feast for me to behold!" The demon cackled, scaring some of the class. It lunged towards the nearest person pertaining to Mineta, but soon it flew away in one direction once Midoriya used air force against it.

"Mineta, are you okay?"

"Thanks Midoriya." The short boy cried.

"These guys can't have their quirks cancelled, plus they have some weird way of healing." Bakugo yelled, flying away from the increasing number of demons while holding Kirishima with one hand.

"We have to drive them away. Todoroki, can you use your ice to hold them back?"

"Yeah." The dual-haired boy responded, "Heaven-piercing ice wall."

Soon, a wall of ice was created to block the intruders, but it did nothing as they broke through, leaving the class shocked.

"Todoroki!" Sero pulled him away from harm with his tape. "Thanks."

"What do we do?" Kaminari asked worriedly.

"Blast them away. What else?" Bakugo stated firing explosives.Todoroki tried using his flames to fend them off, but it didn't seem to work. "It isn't working." Mina cried while spraying them with acid to fend them off.

"Yaoyorozu, are you finished?" Kirishima asked.

"Yeah. Everyone, get under the insulating sheet!" Once everyone was covered, Kaminari smirked, releasing an indiscriminate two million volts. The intruders were slightly shaken, not doing much harm, though.

"It didn't do anything." Kaminari gaped. This only infuriated the demons. They decided to stop playing around.

"Stay still, would you?" One demon growled. Raising its arm about to strike, blood spewed on the floor as its arm went missing. The students gaped in shock. The demon withdrew itself in fear.

"What the hell?! Don't tell me that they are here!" The demon cried out.

"What is he talking about?" Uraraka wondered.

"What happened to his arm?" Mina shuddered in fear.

"Look at its arm." The arm was regenerating, but not as fast as a twelve-kizuki. It was already running away, but before it could go any further, Its head shot off from the rest of the body. Genya frowned; Inosuke didn't cut the head off first.

"Genya!" The class exclaimed.

"You just shot off his head." Mineta screamed.

Genya ignored the class, much to their confusion. They all turned to the demon slayers, who had unsheathed their swords. They split off, battling the demons like it was nothing.

"Water breathing, first form: water surface slash."

Tanjrou smoothly decapitated the demon. He gripped his sword in shock. I wondered how his sword was able to produce water-like effects. He saw the movement of water as he swung it.

"Flower breathing: fourth form: Crimson Hanagoromo."

Kanao dodged the incoming attack and landed hers gracefully. Flower petals swirling around her and her sword while doing so. She paid no mind to it and decided to continue getting rid of the demons.

Zenitsu jumped back, maintaining his first-form stance.

"Thunder breathing first form: thunder clap and flash: six fold.".

Streaks of lightning can be seen around him. Thanks to him, the numbers decreased by a great deal. Inosuke was practically slicing his opponents with ease. He sliced one that his teacher was struggling with before moving on to the next one. Nezuko gave a kick to the jaw of one demon and kneed it.

"Nezuko!" Tanjirou called to his sister when a demon pierced her arm from behind. She growled angrily, forming a fist and knocking the wind out of its lungs. Mina and Tooru gasped at Nezuko's condition.

"Move Midoriya!" Midoriya urged himself to move to help the girl. Along with Bakugou, who was eyeing the rest,.

'Blood demon art: Exploding Blood!'

A pinky-reddish hue of flames burst from the demon that came into contact with her blood. The cry of agony was unbearable to some, as they were outweighed by her strength.

The only things left were the fading ashes of the demons. All the demons were eradicated, so to speak. The slayers were surprised greatly by the effects caused by their breathing. Kanao said it was probably because they were not in their world anymore. Tanjirou complimented his friends breathing effects. Inosuke had a funny feeling inside him but still urged the teen to praise him more. His breathing style created a faint blue slash from his sword. To be honest, Tanjirou wanted to know what it would be like if he used Hinokami Kagura breathing. No wonder their Nirichin blades looked different.

"Hey! Bakugo, what are you doing?" Kirishima yelled. The class whipped their heads as Bakugo exploded his way to the slayers. Iida had just arrived with Vlad King, Present Mic, Midnight, All Might, and Nezu. He was confused as he wondered what had happened while he was gone.

"YOU EXTRAS!" Bakugo shoved past Inosuke, not wanting to deal with him now. "HOW DID YOU DEFEAT THOSE VILLAINS?"

"With our quirks." Silence ensued for a few moments before Bakugo exploded.

"You little-"

"Cut it out! Right now." Aizawa instructed. Bakugo growled underneath his breath. The students didn't even bat an eye at his behavior, as they were already used to it. They were sensing a dangerous aura from the new guys, except for Tanjirou and Nezuko, who appeared innocent. Tanjirou simply thought that he and Genya were alike in their hot-headed nature.

"Mr Aizawa. "They just, you know." Ojiro stammered. Some couldn't help but agree. They just decapitated them like it was nothing. Aizawa sighed, not knowing what to do at this point.

"I think I know how to solve this case." The mouse-looking principal said he was coming into view from All Might's suit.

"We have a lot of explaining to do." The students arched an eyebrow, wondering what they meant.

Taisho secrets

* Kirishima urged Bakugo to step away from the squad after sensing a deadly aura.

Mineta was slightly traumatized by what happened earlier.

*Tokoyami commented on how darkly they got rid of the demons.

The slayers were able to fight due to their senses and flashes of light brought by Todoroki and the others.

* Author-San hasn't seen any updates about the popularity poll. Should she extend the deadline until the end of this arc?

* The people to be voted for should be chosen from class 1-A, the Kamaboko squad, and recent pro-heroes from this arc.

Preview

"Hey, Author-san said that she hasn't seen any candidates for the poll." Kirishima spoke to his two friends, who were chilling by playing video games.

"Seriously?" Kaminari didn't spare a glance, as his eyes were focused on the game.

"Well, people are free to say who they think is the most popular in the arc. Yo! Dude, stop wasting your lives!" Sero exclaimed.

"Where is Bakugo anyway?"

"Bakugo simply scoffed after hearing there weren't any results so far. He didn't want to be part of the preview."

"Dude's ego must have hurt."

"Not yet. Let's see the results. Wait, Kaminari, what did you do?" Sero gaped at the screen, which showed their loss.

"Next: Chapter 17: Spinner's thoughts. Let's play another round."

"Nope. Kirishima wants to trade with Kaminari."

"Dude!?"
