Law was easily adjusting to his current life as a Substitute Teacher in U.A

After going to The Villain Rehabilitation Hospital to check on the Villains due to the orders of the Police and meeting the Villain who almost Disintegrated him, he went back to U.A to speak to Nezu.

Law was currently standing on the grandiose door of the Principal's Office, he raised his hand to knock but the door just automatically opened, and there Law saw Nezu sitting in his chair with his usual Teacup in his hand, admiring the smell of the fresh tea that he brewed.

"Now why don't you take a seat, Mr. Law." Nezu said as he urge Law to seat and he obliged

"I just got back from that Rehabilitation Hospital where they keep those Villains, I'm surprised that they're not getting a harsher treatment considering they're dangerous bunch." Law said as he took a sip of the tea that Nezu prepared for him

Law then finished his tea and placed Shigaraki's Heart in front of Nezu's Table

"As long as I have this, that Villain won't be able to escape, I have his life at the palm of my hands after all" Law said while smirking, Nezu just stared at Shigaraki's beating heart and sighed as he looked outside of his window, the dusk had already covered the sky and the moon was in full view, Nezu saw this as an opportunity to tell Law something about Shigaraki as he began to talk.

"Well, you see that Villain, Tomura Shigaraki is a special case, his former name was Tenko Shimura, and he's the Grandson of All Might's Former Master..." Nezu solemnly said as Law immediately went wide eyed at this Information and smirked

"A Villain is a Grandson of a Hero? Seriously?" Law amusedly responded at Nezu's surprising revelation "Well that guy's the Grandson of Garp the Hero and the Son of Revolutionary Dragon so..." Law thought as he remembered Luffy's weird Family

"Yes, Shigaraki was the Grandson of All Might's Master, Nana Shimura" Nezu simply said before slumping down at his chair while Law stared at him in silence

"Shigaraki might be unredeemable at this point, All for One had corrupted his mind to the point of no return..." Nezu said as he massaged his forehead, he was obviously stressed on what to do now that they've caught Nana's Grandson, the moment Shigaraki became a Villain was the moment he already lost his Future.

"Just let him rot at that place for all I care, all I want is to get back to my Crew..." Law declared as he walked out from Nezu's office, Nezu didn't stop him as he knew that Law must be tired and still complied to their unreasonableness

"Toshinori sure is late..." Nezu wondered as he refilled his teacup with fresh tea, his attention was then stolen by the beating heart of Shigaraki that was placed in his table, Nezu's eyes reflected the Heart of the Grandson of the person that he truly respected, Nezu wished he could arrive at a decision that he wouldn't regret...

But suddenly something ominous happened... Nezu saw Shigaraki's heart disappear...

or rather Disintegrated.

Nezu was unable to hide his surprise as he hold the Crystal-like box that used to encase Shigaraki's heart, the Box was empty and devoid of the Heart that was just beating seconds ago.

With a loud thud, Nezu dropped the Crystal Box as he struggled to keep standing, he sat back at his chair and held his head down as he began to process what had happen.

Nezu was smart, he already knew the reason why Shigaraki's heart disappeared and was reduced to dust, but his mind wouldn't accept it that...

Shigaraki Tomura had died.

U.A Height's Alliance

After his talk with Principal Nezu, Law went to drag his tired body back to the dorms to rest, he saw that the Lights in the room was still open so he assumed that Luffy and the Villains currently living with them are still up so he entered the room and then...

"What the hell are you guys doing?" Law said with his eyebrows raised

"Nothin' much, just playing!" Luffy responded with a grin, he was currently holding the two Villains in question, Twice and Toga on his shoulder and was obviously on the run, Law was then startled by a loud yell that pierced his eardrums

"WE'RE NOT FUCKING PLAYING, GET BACK HERE YOU FUCKING MONKEY!" Bakugou hollered as he chased after the running Luffy "GET THOSE VILLAINS DOWN HERE NOW!, LEMME KILL THEM!"

"N-O-P-E~" Luffy teasingly said to Bakugou while sticking his tongue, Bakugou who's face turned red with anger then grinned

"Fine... if that's how you wanna play, THEN I'LL FUCKIN PLAY WITH YA!" Bakugou yelled as he launched himself at Luffy using the momentum that he gained by using his Quirk

"K-Kacchan, using your Quirk in the Dorms is against the rules!" Izuku exasperatedly said while catching his breath, Law assumed that Izuku really tried his best to stop those two idiots

"YOU DUMBASS PUT US DOWN ALREADY! I CAN DEAL WITH THAT PIPSQUEAK MYSELF!" Toga screamed as she tried to escape from Luffy's rubbery grip but to no avail.

"I-I can't get married anymore..." Twice just gave up.

"This is what I came back to..." Law tiredly sighed, looking at the state of the Dorm, he would rather sleep outside or somewhere peace and quiet

The state of the dorm was in utter chaos, he was just gone for the half of the day and when he returned the Dorms already turned to this mess...

"Oh, you're already back Law-sensei, Good work." Todoroki said as he greeted Law

"You and Izuku-ya are really the only normal ones in here..." Law tiredly said as he didn't want to deal with anything anymore so he just went to his room

"Uhm, Thanks?" Todoroki replied while he cutely tilted his head in wonder

Law arrived to his room, washed his face, brushed his teeth and laid on his bed.

He was tired but for some reason he couldn't sleep, His mind was currently occupied as Law continued to think of the things that recently happened...

How he and Luffy arrived at this strange world after seeing the Poneglyph, and how this world had uncanny similarities to their former world which also had a bizarre Power System, like how there are Devil Fruits in their World, this World had Quirks. How there are Pirates and the Marine in his World and now there are Heroes and Villains in this World.

What's stranger is that the Poneglyphs which shouldn't be here in this World were found by Nezu and his team of Researches that he gathered to help him and Luffy get back to their World.

"Am I overthinking to much...?" Law thought as his occupied mind made it harder for him to fall asleep.

"No matter, there's only one left of the Poneglyphs that is missing, and if Nezu finds it, I hope we could get some clues or answers on how we'll get back..."  Law tiredly thought and closed his eyes as sleepiness slowly overcoming his whole body as he peacefully fell asleep.

"E...GEN...CY! MER...CY!"

"What's with the noise so early in the morning?" Law grumbled irritated, he was woken up by loud screams of someone in the Dorms as he slowly raised from his bed.

Suddenly his door burst open and Law saw an teary eyed Izuku ran into him

"L-L-LAW-SENSEI EMERGENCY!" Izuku yelled out while panicking, Law was dumbfounded at Izuku's action as the green haired teen relentlessly tried to pull Law out of his blanket.

"Calm down first Izuku-ya before you tell me what's going on." Law calmly said to Izuku who nodded furiously, Izuku was trying hard to calm himself down, he quieted down but he was still crying.

"I'll explain everything, this kid is overwhelmed by his emotions right now so I don't think he'll be able to explain the current situation properly." Law heard a familiar voice in his door and saw Aizawa behind Izuku

"What happened?, Aizawa-ya." Law was now wide awake and was curious of what had happened for Izuku to shout EMERGENCY out loud first thing in the morning...

"All Might's gone missing... we've been searching for him during the night and he hasn't been found until now..." Aizawa with an obvious serious tone in his voice, Law was clearly confused by this.

"He could've just gone to save some people since he's a Hero" Law simply replied to Aizawa who just shook his head and responded

"If he did he would've come back during the night in U.A, Principal Nezu was always concerned about him so All Might always comes back after he's done being a Hero and when he didn't come back last night Nezu Immediately issued a nationwide search for All Might." Aizawa said to Law, completely explaining the current situation to him in full detail.

"Toshinori-ya doesn't have any Family right?" Law asked to Aizawa who shook his head again

"No, that's why the only place he could return to is here in U.A..." Aizawa as a matter-of-factly said to Law who was now hit by the sudden graveness of the situation...

"Toshinori-ya is called as the Greatest Hero here... If something happened to him the people will surely feel uneasy..." Law deeply thought as he stood up, suited up and grabbed his Kikoku

"I will also help with the search, since were both Teachers I might as well help." Law said to Izuku and Aizawa who raised a brow

"You're also a Hero so your help is really needed..." Aizawa lowly replied to Law who secretly swallowed his saliva at this

"With Law-sensei's help we might be able to find All Might! hopefully..." Izuku lowly said but knowing that Law will help them search for All Might cheered him up.

"I completely forgot that I'm still a registered Hero here... what a drag." Law irritatedly thought and was clearly upset by this.

Location: Kyudai Garaki's Hospital

In the Hospital filled with malicious intents and darkness was the Greatest Hero...

Covered in bruises, scars and his own blood, there was All Might.

All Might was beaten up, chained down and is close to death's gate, His Promise to Izuku and His indomitable will to live were the things that is keeping him alive.

All Might slowly blinked and looked up as he heard footsteps getting closer and closer at him, and then he saw him...

"You look so pitiful, All Might..." All for One said as he grinned evilly at the sight of a dying All Might who's struggling to live.

"A-All for One..." All Might quietly said as he glared at All for One who's currently in front of him.

"Not only did Nana Shimura died a pitiful death, but you also dying at the same pitiful way is truly laughable..." All for One mockingly said to All Might who gnashed his teeth in anger

"DON'T YOU DARE MENTION MY MASTER'S NAME WITH YOUR FOUL MOUTH, ALL FOR ONE!" All Might angrily yelled out as he mustered his remaining strength to mouth off All for One who kept his grin.

"HAHAHAHA, You truly are pitiful All Might, not only you will die, but also the Peace that you've built up in your entire life will finally collapse!" All for One maniacally laughed out loud, All Might could only stay silent as he bit his lip in shame for being defeated.

"Killing you here would be boring, I will make sure you see through all the things that you've built up DIE OFF..." All for One said to All Might in a chilling voice

"Yes... Including those fools from that pathetic Hero School..." All for One grinned widely as he saw All Might's face painted with despair

"AHHHH, SEEING YOUR GRINNING FACE TURN INTO A FACE FULL OF HOPELESSNESS AND DESPAIR, I CANNOT GET ENOUGH OF IT, HAHAHAHAHA" All for One laughed out loud, All Might was shaking in anger but was too powerless to do anything...

"Y-You evil b-bastard..." All Might could only utter those words as he lost his remaining strength and passed out... all while hearing the unchanging maniacal laughs of All for One, The Incarnation of Evil.
