Summary : While he was returning home after a day of classes all that was normal for the Vongola Decimo, or : disturbed by various explosions, the unexpected arrival of a certain pineapple illusionist, the dodge of a disciplinary committee leader, and many other problems, Tsunayoshi loses consciousness and wakes up in an unknown place, facing a strangely dressed nurse, and who says even more bizarre things.

Wait, how did he get transported to a parallel universe again ? Alter ? Hero ? Are all these people sane, by the Primo's underpants ?

In short, a new adventure for Tsuna and his friends, where he will learn to become a hero, and incidentally save the world from destruction... Oh ! Had he mentioned that the Earth was communicating with him, and that he had fallen in love with a notorious Villain ?

Important : I changed the ages of the characters, here Shigaraki is 17, Tsuna is 15 but 16 in like two months. I have no idea why I ship them, but it came naturally soooo here you go ! Also, MHA have some canon divergence that you will see among the story ^^

Parrings : Tsuna/Shigaraki, 8059, 6918, Eraser Head/President Mic. Apart from the main parring, the others will be in the background, and I'm not even sure they will appear at some point, but in case I put them to you.

Hello hello !
Here I am with the third chapter in time, who would have believed, fixed by my beta Nurikuro thanks her !

The hero with shells

Chapter 3 :

The crazy shopping trip

Before he had time to breathe Tsunayoshi was already in the middle of a shopping mall following in the footsteps of a grumbling Aizawa-sensei. Things had quickly advanced once the long, long, discussion with director Nezu was over. It seemed that the shadow hero charged with accompanying Tsuna was on the same wavelength of wanting to finish this chore as soon as possible.

Of course, it was easier said than done, given the amount of things he needed. In addition to all kinds of clothing, he had to buy furniture for the bedroom of his future dormitory, his school belongings, a few books and a dozen other things that he could use.

The brown head had thought about making a list before leaving, but now that he was surrounded by all these shops, he realized that he had not thought about half of what was needed. Still, he was glad it was not a whole apartment that they had to furnish and make habitable as soon as possible. They would be here until next month !

Aizawa made them stop in front of a furniture shop to begin with and Tsuna raised his head to him trying not to be distracted by the whole life around them. He rarely had the opportunity to go to Tokyo before, so even if it was not exactly the same as the one in his universe, the city was no less captivating.

"Sawada. Come in. I'm not going to hold the door for hours."

The brunet felt his cheeks burn with shame as he hurried in, muttering an apology. Not seeming to notice more than that of the apparent clumsiness of the teenager, the teacher thrusted his hands into his pockets. He pointed with a gesture of the head to the tables scattered all over the room where a multitude of small models of miniature furniture lay.

"Look for what you think is best, I'll make sure it will be delivered before tonight."

Tsunayoshi nodded, relieved to see that he would not have to spend another night in the too white infirmary, and trotted towards the stalls. It took him only about ten minutes to look curiously around him, (in search of something to recreate his room in Namimori) before he was finished.

The last time he had been thrown into another reality, he had to live in a shared room with Hayato and Takeshi. Some nights had been quite amusing in truth, almost like sleepovers. Life together had not bothered him more than that. The snoring of Takeshi and the mumbles of Hayato had been something reassuring.

No, the problem had been more in the fact that they did not know when they would be able to go home. The stress and constant heaviness of his responsibilities had weighed on the Decimo's shoulders throughout his time there, leaving him with little opportunity to relax. He had many times dreamed of just being able to return home, to the illusion of protection that his room brought. Here, he had the opportunity to recreate it even if everything wont fit perfectly. His gratitude to those adults who, for once, did their job well, sparkled in his chest, pulling him a nice little smile.

Wasting no more time than that he returned to Aizawa, who had taken out a book and settled in a corner, occasionally raising his head to check that everything was fine. The Sky blinked at this behavior he had seen so many times from Reborn, and to a lesser extent Gokudera, before biting his lower lip, preventing himself from snickering stupidly. He doubted that the teacher would appreciate his laugh, as he could very easily see It as mocking.

As a result, he only received a suspicious glance, and a couple of minutes later they were in another store, of clothes this time.

Swallowing, he faced the mass of customers and articles. Tsuna was suddenly eager to turn around and just to run away from this hell. He ended up putting one step in front of the other, with Eraser Head at his heels in the shop, not allowing Tsuna to stray too far from him at the risk of… well…

…At the risk of… what exactly ?

Here, he was just a kid like any other who had, well, inadvertently been projected into another world. He could understand the need to have someone with him to prevent him from being lost and to pay for furniture, but here was nothing that justified such protection.

Shouta did not seem particularly suspicious of him, having come to terms with the fact that he was a strange teenager, but he was careful to get between him and anyone who got too close.

Oh, nothing very apparent, but when you spent your days framed by two 'bodyguards' like Hayato and Takeshi, it was the kind of thing that you noticed more easily.

Frowning, he lifted his head, (previously buried in piles of T-shirts) up to his teacher, vocalizing his confusion.

"Aizawa-sensei ? Is…there something wrong…?"

The professor lowered his gaze to the brown head, raising an interrogative eyebrow.

"I mean... You seem to be expecting something so..." Mumbled Tsuna, his eyes fixed on the ground, uncomfortable. He had never been good when it came to interactions with authority figures, and his father's almost perpetual absence played a big role in it. The oddity that had become his daily life after Reborn's arrival in it had taught him more how to deal with extreme cases and children, rather than much more normal teachers. Well, as normal as a supposed Hero teacher can be…

Crossing his arms, and watching his pupil curl up mentally on himself, Shouta sighed. It seemed that the Sawada was going to be a thornier case than expected, if the obvious lack of self-confidence he was showing at the time meant anything.

The boy was an enigma. He adapted dreadfully quickly to events and, the fact that he had been transported to another dimension. Although Shouta himself still finds it hard to believe, it did not seem to panic him more than that.

He squinted, trying pointlessly to find his answers by staring at the teenager, who was really beginning to wonder if he had said something stupid to receive that look. He was going to have to keep an eye on him even if it pleased the Headmaster that was far too inclined to let potentially dangerous strangers pass through Yuei's doors, or not.

"I'm just being careful. It is not safe for you to be in such a crowded place while you're with me." Finally sighed Eraser Head, not particularly liking the nervousness that transpired from the kid caused by his lack of answer.

The kid looked up at him and looked... Suspicious ? Not of the potential threat of which he knew nothing yet, but of Aizawa. Huh.

"Why is it dangerous to be with you, Aizawa-sensei ?" Was the answer that soon arrived, and he had to restrain himself from not smiling at the impression of badly licked kitten that Tsuna gave.

This is yet another shady element related to the Sawada. This kind of reaction was not normal for a 16-year-old, and it was particularly detonating on the clumsy-looking little browns innocent head.

Do not get him wrong, Aizawa did not complain of the sight of a little bit of suspicion in the student's head. Actually, he preferred that than to the blind trust that some others had in him. Which, even if felt warm, remained dangerous. Trust was a double-edged sword, and one that, if misused and placed in the wrong hands, could do a lot of damage.

But this kind of caution usually came with a whole bunch of traumas and childhoods-not-as-sympathetic-as-it-seems-at-first. This meant even more work for him as he is responsible for mentoring and helping these children find their places.

Thrusting his hands into his pockets, the teacher came out of his thoughts with a tired sigh.

"Ah... We must have mentioned it earlier I think ? The League of Villains has repeatedly targeted Yuei's students this year, as well as its teachers, so..."

He did not finish, leaving the teenager to find the necessary conclusions on his own.

The little grimace that appeared on Tsunayoshi's features at the mention of the League could have been comical in another context.

That name really was ridiculous.

Even the Varia had made the effort to find a more original name than the simple description of their function. Well, it was based on their varying uniforms and switching members, but still.

The tension in the jawbone of the man in front of him that appeared earlier, clashed with the calm feeling he tried to diffuse, like a mask worn more out of habit than conscious action. Aizawa-sensei had to be directly affected by these attacks to have this kind of reaction…

Trying to ignore the impression of déjà-vu at the announcement of a new yet unknown threat, the Decimo asked his question, which he already knew the answer to.

"But I don't wear a recognizable uniform, and they don't know me..."

Aizawa squinted slightly, raising a nonchalant shoulder.

"You're still a teenager, it's better to be careful. They are dangerous Sawada, it's not the kind of group you want to fritter with."

'More dangerous than a timeless global organization in charge of mafia prisons, a bunch of professional assassins determined to kill you and your friends, or a megalomaniac who can travel between the dimensions that almost got his hands on one of the most powerful forces in the world ?'

Tsunayoshi closed his eyes for a moment, holding back from expressing his thoughts aloud. He merely nodded, wondering what he might have done in another life to have so little luck.

Quite honestly, he did not care a bit about this League of Villains, and was much more worried about his friends whom he had still not heard from. He felt it would fall on his shoulders at some point, but, without any arrogance, doubted that a band of 'Villains' playing with their powers (and annoying students whose future job would be to control these kinds of characters) would be a very great threat to him.

He could already hear Reborn's voice in a corner of his mind, jeering him that he was becoming too sure of himself and that he should never underestimate an enemy, especially one he knew so little about. Screw him ! His tutor was not here to pull him by the ear for having the audacity to think that.

Returning to his t-shirts to hide his little ironic smile from the shadow hero, Tsuna thought that he could delve into his denials for once, as the others would handle this problems without asking him for anything, he was not going to rob himself of it.

About twenty minutes passed without disturbance, during which he amassed a quantity of clothes for his time here. Which he hoped would be as short as possible…. He was already missing his guardians, and this was beginning to be reflected in his Flame.

Being separated from Its elements for a long period obviously ended up bringing out negative effects. In addition to the obvious loneliness associated with the absence of his dearest companions, the growing emptiness and feeling of lack could easily make an isolated Sky miserable.

The more powerful and close the Sky was to Its elements, the more the effects were felt. This could be partially eased if It surrounded Itself with other elements powerful enough, but the Vongolian rumors whispered that it could even end up being deadly…

Tsunayoshi pursed his lips, clutching the orange sweater he was holding in his hands, and drove away those disturbing thoughts. A faint burning reflection slipped through his chocolate eyes, unbeknownst to all.

He would not die that easily ! He was going to find his friends, and go home before he could even get used to the strangeness of seeing people with wings walking down the street.

Nodding distractedly at his professor who had to move away to take an important call, (although seeing the color his cheeks had taken, Tsuna doubted it was related to his job) the young man took a step back, glad to have found his size.

His Intuition reacted a little late, since It could not prevent him from jostling the person who was passing behind him at the same time. Yelping, the Sawada hurried to apologize, bowing several times.

When he finally lifted his head to see the face of the person he had inadvertently jostled, his chocolate eyes met the ruby of the stranger. A stranger who seemed awfully irritated to have to talk to him.

Tsuna did nothing more than blink at the sight of the damaged face of the young man hooded in front of him, having already seen much worse among the old Arcobaleno of Vindice.

No, he was more intrigued by his Flame of Storm, which was bubbling with contained power, and which cried out loneliness.

It was one of the strange features of this world that he had taken a little while to notice. Here, most people had half of their Flames activated. No one seemed to know how to use them in their most primitive forms, but it only took a little concentration to feel the burning essences of these people. The mass was still very weak, and that seemed to be the norm, with rare exceptions, although he could not quite explain it.

Of all those he had met up to that point, except perhaps Aizawa-sensei whose own Flame of Rain radiated, the white-haired boy must have been the most powerful. Ignoring the small pinch in the heart that accompanied the brief memory of his right arm, the Vongola bowed his head to the side, confused.

His intuition did not seem to know what to tell him. It was just going from "Danger !" to "No problem, he's a friend." And was seriously beginning to give him a headache, in addition to being perfectly useless ! It was as if the stranger had not yet decided whether to rip off the little brown's head, or kindly pat him on the shoulder before going his way.

"Hey."

Tsunayoshi suddenly jumped out of his thoughts as quickly as he had immersed himself in it. Damn attention disorder. Twiddling the orange sweater he still held in his arms, he stammered a 'yes?' (more squealed than anything else) not expecting the boy to engage the discussion when he was still on the verge of throwing him into the shelves.

Seeing that he now had his attention, the taller frowned a little less, and his deep, slow voice sounded again.

"Your name ?"

The Decimo blinked a little stupidly, but seeing the eyebrows of his interlocutor bend down again, he shook himself and hurried to answer, leaving his questions aside for the moment.

"T-Tsunayoshi ! Tsunayoshi Sawada !"

He grimaced at the irregularity of his voice, trying very hard not to fall in one of his internal monologue where he spent most of his time insulting himself and cursing his stupidity/clumsiness/any-part-of-him-that-posed-problems.

The other boy continued to stare at him as if he were an insoluble enigma, but at least his Intuition had calmed down in a good way.

"I'll remember that."

And he turned around, already walking away without further ceremony.

'Really?'

Imitating a fish out of the water for a moment, Tuna* finally reacted without really thinking about it, reaching out to the stranger to hold him back.

He grabbed the edge of his sleeve, and the ruby eyes, shining with irritation, turned again upon him. He did not know if he should be nervous…

"What ?"

Sensing that the other boy was close to leaving without listening to him if he did not hurry, the Sawada tightened his meagre grip on the garment and launched himself.

"A-ah well... Can I know your name too, please ?"

His shoulders stretched to the sound of his own voice, whose tone was much more begging than expected.

Ah. Here is the look of 'I-can't-determine-of-what-species-you-are' again.

Attempting a small smile, Tsuna leaned his head to the side.

It may have been a little selfish of him, but he did not want that Storm that seemed to subconsciously call a Sky with loud cries to disappear so easily.

From what he had been able to see, the Flames did not appear to have spread as they had in the future of his own universe, same with the rings, so the boy himself must not understand what was going on, and happening to him.

Clinging to his belt near his back pocket, Natsu gave a little blow in his box, making it move enough for the brown to notice. It had probably perceived the conflict in his owner, and being unable to appear in the eyes of all, the Box Weapon tried to provide support as it could.

He blinked several times, and refocused on the person he was currently talking to, cursing his inability to stay out of his thoughts.

"...Shigaraki. Tomura."

The silence that had stretched had surely lasted longer than decency would have tolerated, but neither of them cared.

The smile on the brown head grew, as he released the poor young man, nodding, his gaze softening.

"Enchanted, Shigaraki-kun."

A new confused look. Then the white man nodded at him before leaving quickly.

This time he did not try to stop him, even if the urge was there. His Intuition whispered to him that he did not have to worry… Maybe they will see each other again soon ?

"He was a bit strange..." He said aloud, musing.

Natsu gave his box a flick again, as if to say, 'you're one to say that !'.

Softening a little laugh, the Decimo shook his head. He had nothing against it after all. His life had been full of strange things since Reborn's arrival.

Aizawa-sensei returned a few minutes after that, (grumbling about idiots with too loud voice, if he understood correctly), and they soon continued their shopping tour, much to the displeasure of the two participants.

There were a lot of people in the mall, and his Intuition was throwing little spades at him to keep him on the lookout. Something was going to happen, and Tsuna had to be on his guard.

They entered an electronics store, just to get a phone for the Vongola since his had not made the trip with him. He missed his photos, but he did not really have a choice.

With his eyes fixed on the exorbitant prices of the new models, Tsunayoshi began to play nervously with the ring around his neck, still hidden by his clothes.

Because of his intuition that was warning him of an as yet unknown threat, he could not concentrate on the babbling of the annoying salesman who preached the merits of this new device at the cutting edge of technology, but which, in view of the face of Aizawa-sensei, seemed to be as useful as a cucumber.

Sighing, the teen shook his head, trying quite futilely to chase away his headache. He gathered his courage and spoke when the salesman stopped the almost constant stream of words he had been swinging for 10 minutes, to breathe.

"Um, I think a simple used clamshell phone will be enough..."

Shouta shifted his attention to his charge, frowning slightly.

"Are you sure..?"

A small smile bloomed on the lips of the Decimo, who opened his mouth again getting ready to answer, but was cut off by the overly talkative salesman, who rubbed his hands with a smile as fake as the one Hayato wore when he was really upset.

Tsunayoshi frowned, disgusted by the dripping hypocrisy of 'Suna', as indicated by the badge on his chest.

"Oh, how lucky you are dear customer, to have a son so responsible for your expenses ! Allow me however, to insist on the importance of a device powerful enough not to..." he continued for a while, not seeming to notice that neither of his clients were listening.

Tsunayoshi nearly chokes on air, his cheeks burning, while his teacher was strangely silent, and his cheekbones suspiciously colored.

The brown averted his eyes on his shoes, shoulders raised up to the ears. The opposite of the event 'a student calls their teacher mom' had to look like this...

The hero finally cleared his throat, effectively cutting off the irritating salesman's chatter, and tried to explain himself, not quite daring to cross the gaze of the teenager, who did everything to avoid him as well.

Danger !

"Um, actually this is-"

The professor never had time to finish as Tsunayoshi tackled him on the ground after a brief "CAREFUL !" shouted in response to the warning of his Intuition.

The next second, a sniper bullet went crashing into the wall, passing close to Aizawa's hair, and that would have ended up right in his forehead without the intervention, muscular shall we say, of the Decimo.

There was a moment of floating during which no one moved, until the information ascended to the brains, before a panic movement was triggered. The salesman who had taken refuge behind his counter, left shouting full lungs towards the exit, dragging a crowd of customers equally distraught with him.

Tsuna grimaced, knowing that it was the worst thing to do in a potential shootout to panic like this, but did nothing more, his Intuition having completely calmed down. The absence of any more shots was also an indication, and he preferred to refocus on the grumbling professor he had brought to the ground unceremoniously, than on the fugitive sniper who was probably going to be yelled at for having missed his target. He sympathized a little…

"Everything all right, Aizawa-sensei ?"

He himself was more than used of shots, especially directed at him, thank you Reborn, and his reflexes had made him react in time.

The hero nodded, seeming a little shaken, and stood up cautiously, still standing covered. His gaze quickly passed over his pupil, checking that he was not injured, his eyebrows frowning like never before.

"Nothing broken on your side ? How did you..."

He stopped when he saw the amused smile of the Sawada, bemused. They just failed to get shot, and the kid was smiling like it was perfectly normal.

"Intuition. I told you it was reliable."

Shouta blinked several times, before letting It go.

"Oh. Thank you Sawada."

Tsuna shrugged, as if to say, 'it's nothing', as if he had not just saved the shadow hero's life from an undetectable threat, if not for his Quir- his gift, sorry.

The quickly emptied store was soon filled with other heroes on duty, tasked with checking on the situation, and seeing if no one had died stupidly trying to escape. Or by taking a bullet, incidentally.

The two got up, and Aizawa approached the group of heroes to tell them what had happened, sending half to chase the fleeing sniper.

Tsunayoshi thought it was a bit stupid if you wanted his opinion, since they were not likely to catch up with the person who had been professional enough not to try again when his first had missed, which would have risked revealing more information about themself. Of course he kept his thoughts to himself, and instead leaned over the bullet impact in the wall, distractingly noting the model of the rifle with which it had been fired.

Reborn had taught him to recognize any gun just by sound and bullet, and the weeks of training required for him to reach a level acceptable to his tutor had been a hell...

He shuddered at this memory, preferring to re-rent it well deep within himself rather than go over, and trotted instead towards his teacher.

Aizawa had warned him of the possible danger he was risking being with him, but in view of the confused frown of the man, he began to think that this attack may have had nothing to do with the group named earlier…

Picking up the fallen bags, Tsuna distractedly threw out a comment.

"You have a lot of enemies apparently, Aizawa-sensei."

If ever discovered (and these if tended to turn out to be a little too truthful for his liking) that assassination attempt had some Mafia connection, he needed to know it. First, to help his professor, because despite the short time spent together, he liked him, and then to call the Vindice if his said professor was just a collateral victim.

The prospect of seeing Bermuda and the other cursed Arcobaleno did not enchant him any more than that, even in a parallel world, but someone had to stick to it.

It was highly unlikely, and his Intuition was not reacting more than that, so he was probably just overthinking.

An irritated grumbling from which he had been able to draw a 'It seems so' was all he gained as an answer, before the older one changed the subject. Shootings did not really seem like a common thing now that almost the entire population could make damage with their Quirks.

"We should go home. I have to fill out papers because of what just happened, and we've gathered enough stuff for you to live on while you wait for the rest."

Shouta glanced at the phones in the window, and pursed his lips for a moment, before continuing.

"I'll get you a phone on the way, we have to get away from here."

Tsunayoshi nodded without making a fuss, and followed in the footsteps of the oldest, making sure he had not forgotten anything behind him. He might have not reacted to this attack as anyone else would, but honestly, it lacked the flavour of a Poison Cooking, or a shower of silver knifes.

Being around murderers on a daily basis for years tended to have that effect.

But excuse him ! He had luggage to unpack, and furniture to assemble ! Bothering about a failed murder attempt was not in his top priorities.

*Tuna… Fish… I'm trying to be funny okay ? Leave me alone

And done !
