Aizawa had never felt so burdened with people in his entire career as a teacher. Being a teacher to twenty teenagers including the six demon slayers and mature hashiras with 'unique personalities' was overtime for him. Sitting next to the kitchen counter with a cup of coffee in hand for the past ten minutes, he dared not to bat an eye at the scene behind him.

However, his curiosity was peeked by the sudden lively voices. His eyes trailed to the common room slowly assessing everything.

Nothing out of the norm...Fortunately. Tanjirou and Kanao were introducing Giyuu and Muichiro to the rest of the class. Zenitsu, Nezuko and the girls were talking to Mitsuri.

Sanemi and Iguro engaged in a conversation of their own far away from the rest. Inosuke chased All Might...

Definitely nothing out of the norm...but....

Shinazugawa Genya.

He recalled the moment Genya left. His expression unreadable and voice accompanied with a sad tone.

He should probably go check on him. At that moment he stood up, his phone rang. Without hesitation, he answered.

"Who am I speaking with?" His face plummeting as he listened to the speaker. He ended the call and turned to the group. He gave a nod to All Might entrusting him with the class and slayers.

"Wait what about Hashibira?" A huge weight pounded into his back forcing him to land on the floor with Inosuke on top of the blonde retired hero.

"Too slow!" The boar headed boy cackled. His celebration cut short, muscles tensed due to the fabric wrapped tightly around him.

"You're coming with me." Aizawa informed pulling him along. "Don't even try to struggle. Got that?"

Inosuke nodded begrudgingly while being pulled away.

"Aizawa, what came up causing you to leave?" All Might stopped the man in his tracks.

"I just got news that Shinsou isn't back in his dorms. It is way past curfew and no one has been able to reach him" He unfolded. All Might nodded understanding the situation.

"Be careful out there"

"I could say the same to you." All Might deflated realization hitting him. He was left to look after the entire students and Slayers. He looked at Aizawa anxiously but the pro hero smirked a bit and left with Inosuke.

Calm down Toshinori...It's just a bunch of teenagers and unique people. How bad could it be?

With a determined resolve, Clenching fist, his gaze darted at the Bakusquad who were close too Iguro about to touch Kabarumaru.

All Might sighed and facepalmed not prepared for the upcoming reaction of the snake pillar.

"Hm?" Gyomei perked up at Shinsou's voice. Was he not familiar of who they are? Every demon can tell a demon slayer from a normal average person alone. Even the weakest demon could identify them by presence alone.

Tengen squatted in front of Shinsou clearly flabbergasted at the sight of him again. "Look kid,

we don't know who you are and judging from that unflashy look on your face...you don't know who we are either but it is clear that you are not a demon." He fixated his gaze on him.

Shinsou dumbfounded didn't say a word and let the man continue.

"We need you." Shinsou raised an eyebrow.

"For what?"

"To tell us everything about this place. First things first, why do those things down there look like demons. " The second time hearing the word demon.

"What?! How do you not know about quirks and why do you keep referring to us as demons?" The Purple haired lady asked itritatedly.

"Calm down young one. We just need to know." Shinobu gently assured placing a hand on her shoulder.

Shinsou shrugged her off. "How can I trust you? Why should I trust you?" He faces Tengen. " What type of person randomly kidnaps a someone and asks them for info? A villain obviously. " Shinobu frowned.

I'm just glad Shinazugawa and Tokito aren't here.

"Look kid. I you don't trust us. I understand. Honestly I don't trust you either. What being stands up and offers to help someone he's never met or known before?" Shinsou slowly loosened himself taking that in.

Sighing, he explained everything about the quirk filled society. Shinobu in turn offers info on the demon slayers.

"So if you hasair...Pillars... are looking for a demon king wannabe how come you cant find your way anywhere?"

"That's why we asked. We were transported here by a black void."

"But you mentioned there are no quirks from where you came from?"

"Exactly."

Few metres away from the group, Aizawa and Inosuke were parkouring building with the pro hero using his Binding scarf as aid while Inosuke leapt all thanks to his remarkable unfamiliar abilities.

Sevnth form: Spatial awareness.

Concentrating for a few seconds before opening his eyes with his one of a kind smile he cackled. Aizawa weariky faced him not in the mood to deal with his antics. The laughter continued attracting attention. The pro hero rubbed his forehead and took action.

"What's the big deal, Papazawa?" Inosuke yelled currently captured with the scarf.

Eraser head ignored the new given name as it wasn't new."I thought I told you not to attract attention. Now, why did you do that?"

Inosuke mumbled threatening the man to pull the scarf one more time to which the man gladly did. He huffed and sputtered " I sensed some of the hashiras."

Aizawa recalled and released the boy.

Now that he mentions it, Tsuyuri mentioned that he had an elder sister who is a hashira. There were only three left.

"How many peol-"

Aizawa's eyes narrowed, a vein popping at the side of his head. That idiot problem child ran off.

"Hehehe! As if that old guy could take hold of the great Inosuke-sama" He huffed running towards east. Out of nowhere, a bird smacked his face blocking his sight.

"Wha the hell?!" Before he could continue further, he lost his footing.

Aizawa had already gotten to his trail only to see him tumble. He gaped and dashed fast releasing his weapon.

Inosuke smiled crazily. He readjusted his position in space and slipped between a narrow space. Following suit, he grabbed his teacher's weapon and did a flip with it as Aizawa pulled and landed on the man.

He's a kid Eraser head. Don't-

Aizawa glared at the teen who sat on him proudly and began announcing that he would not be ruled by anyone. He sighed tiresomely and tossed him off much to the boy's annoyance.

"Lead the way. Pull that stunt again and you'll live to regret it." Aizawa firmly said wrapping his weapon.

Inosuke hugged and took off with is teacher behind him. The man focused his attention forward, was that Shinsou? That could mean ... Soon,Both Aizawa and Inosuke landed on the roof of the building.

"Eraser-san!" Shinsou relieved at seeing his mentor and ...

Wait...I've seen him a few times at school. He's a new student in class1-A right?

Que Inosuke picking his ears.

"Inosuke/Ah it's you!" Shinobu and Tengen exclaimed at the same time. The boy in question faced the three hashiras ignoring Shinsou completely.

"You are also in this mess" Inosuke nodded.

"Yeah and so is everyone else."

"How wonderful. Everyone is alive" Gyomei clasped his hands with tears streaming down his cheeks. That didn't stop Tengen and Shinobu from glancing at Aizawa and Shinsou.

The pro hero waved "I'll explain everything if you come with us." His eyes darts to his trainee "and that includes you two" Shinsou didn't even question it. He'd like to get answers of his own... and maybe questioning and scolding from his teacher too.

"Yosh! Let's go!"

Immediately the group returned to the dorm, All eyes landed on them making the room go silent. Surprisingly, Kanao broke it by yelling and lunging towards her sister and hugging at her sister. Shinobu simply hugged back tightly. Everyone slowly began to react as Tanjirou approached Gyomei and Tengen while a possibly lean All Might who got even paler immediately retired not wanting to continue with this any further. The students practically distancing themselves away from the Hashira incase they turned it to be like Sanemi or Obanai talked with Shinsou wondering what he was doing here.

"Tsk...Glad to see more familiar faces here." Sanemi remarked.

"Shinazugawa, Flamboyant as ever I see. Did you miss me that much?" Tengen smirked at the wind Hashira.

"Those bastards can never replace a hashira. Too bad you retired."

"Well, a man has too live life to the fullest."

"You are suppose to fight till you die.Even if you have just one arm and eye it's still better that the rest of the corps." Obanai sharply states.

"You are still holding unto that?"

Tengen deadpanned.

Where's Genya?

Gyomei couldn't help but think. He hasn't heard the boy's voice, could he still be home? As if Tanjirou read his mind, the boy says.

"Genya is here but he said he wanted to sleep early."

"Kanao, I'm glad to see you." Shinobu gently pulled away from the hug looking down as her sister's face that showed a relieved smile.

"Kocho..." Shinobu whipped her head to the source of the voice.

"Tomioka-san,

It's good to see you... now, don't tell me you haven't still made any friends." The man in question froze.

Aizawa clapped his hands gaining attention. " Now that we are all here. I'll explain"

Taishosecret

*Apparently Genya had been feeling uneasy under Sanemi's harsh gaze even while chatting with others and head to bed early.

* Kirishima survived from Kabarumaru's snake bite thanks to his hardening but he didn't escape from Iguro.

*Zenitsu had been keeping record of his daily activities in a journal since he got here.

"Tanjirou it's ben a while. I hope we can hang out more often now." Muichiro gleamed brightly.

"I'm sure we will be able too. Um...Tokito-kun, is something wrong I'm scenting a frightening feeling?"Tanjirou smiled nervously.

"Oh, nothing too serious" He looked behind Tanjirou. Tanjirou peeped in the direction seeing a tied up Midoriya and Iida, both boys sweating nervously while gagged with a white cloth.

Help us...Kamado-kun

Tanjirou...

Tanjirou faced Muichiro nervously. He smiled. "We should untie them"

"Okay" Muichiro agreed. "Next, Chapter 28: Kanao goes shopping."
