Even after getting a good night of sleep didn't help the headache he has due to his HI. It was still there. Still ringing in his head like an annoying alarm clock that won't shut up. But Tsuna learned to live with it, an internal alarm was a thousand times better than the questionable methods Reborn would use to wake him up with. After living through several hellish situations, he learned that a little bit of discomfort was nothing at all. Thus, he tells himself that he can get through the day as per normal despite the constant ache in his head.
He has been keeping his guard up to his surroundings throughout the day but since nothing happened at all, he decided that it would be alright to maybe let himself relax a little.
However, as anyone would've guessed by now, fate has a way of screwing with him and he found out the consequences of letting down his guard the hard way.
It was around lunch period when the intensity of his headache shot up. He was about to leave the classroom with Midoriya and his guardians when he overheard a commotion outside the class. He frowned when he recognized the voice and wondered why in the world would he be here.
He should be in infirmary with Recovery Girl! He quickly ran out of the class and was surprised when he saw the scene before him.
"LET GO! This is Lambo-san's!"
"Oh c'mon! Just let me have a look at it! Just a sec?"
Hatsume and Lambo were engaged in a tug-of-war with one another over a purple bazooka that Tsuna recognized as the 10 year bazooka Lambo always carry around in his ridiculous afro.
"NO! Lambo-san don't wanna!" Lambo stubbornly pulled at the bazooka which was held tightly in Hatsume's hands. The little boy had no chance of snatching back his bazooka with the tiny amount of strength he has.
"Hatsume-san, what are you doing?!" Midoriya exclaimed. From everyone's point of view, it looks like the inventor was bullying the little boy by snatching away his toy.
"Oh! Hi there everyone!" Hatsume turned her head to us and waves, and in the process she released her hold of the bazooka. The sudden shift in gravity made Lambo fall as he tugged forcefully at the bazooka, making it fly out of his hands and into the air.
Everything seems to move in slow motion for Tsuna but he knew what was going to happen before it did. With his luck, he knew what was coming.
Why me?! He whined before giving up to his fate.
The bazooka sailed through the air gracefully and coincidentally—and conveniently—landed on top of him.
There was a poof and pink smoke engulfed the area.
"Tenth!" Gokudera yelled out worriedly but Yamamoto and Chrome were silent, they knew the bazooka wouldn't harm their boss. Plus, this wouldn't be the first time it happened. Gokudera was just being a worry-wart as usual.
However, the bazooka wasn't done with its mischief. It bounced around the room, as though it has a mind of its own. Everyone stayed back from the crazy bazooka, not daring to stop its tantrum.
"What's wrong with this thing?!" Sato exclaimed as he swiftly ducked out of the way. The bazooka bounced happily and took its aim towards a sleeping student on his desk.
"Todoroki-kun! Look out!" Midoriya shouted but it was too late. The bazooka engulfed him, enveloping the area in even more pink smoke. The explosion from when the bazooka fired itself sent it flying towards Midoriya next. But because his worried eyes were still focused on the spot where Todoroki disappeared, he wasn't paying attention to the rampaging Bazooka that was coming right at him. He didn't even have the time to yelp before the bazooka ate him up too.
Everyone was panicking and running away from the out-of-control bazooka, all hoping not to be the unlucky one to get hit with it. The bazooka did one last bounce towards the door and as if on cue, Bakugo's enraged face appeared.
"Shut the fuck up! Why's it always so noisy with you assholes?!" He yells. But that was the last thing he could say for a while because the bazooka conveniently hit him too.
The classroom was surrounded with pink smoke, making everyone cough and wave their arms to clear the smoke away. Someone helpfully opened a window to let it out and gradually the room cleared.
Once the area was clear, everyone looked around for the 4 who got hit but they were nowhere to be found. That is, until they hear a soft curse and groans coming from their feet.
"Owwie..." A boy with brown hair, around the age of 5 groaned in pain as he held his oversize head with his tiny hands.
No... He thought in alarm as he pat his body down.
No...Not this again! He buried his face in his hands in despair.
"Wait...those big doe eyes..." Uraraka pointed at the boy, her eyes wide open and her jaw hang slack. "That gravity defying hair...could it be..."
"What the hell!" A high pitch shrill came from near the door. Everyone turned to see a small, blonde boy with mean, angry looking eyes glaring daggers towards the brunette.
"You fucker! What did you just do to me?!" He yelled and marched right up to the poor boy who was trembling all over.
"Stop it Kacchan!" A small green haired boy came running towards the two and pleaded at the blonde with his huge puppy eyes.
"Shut up Deku! You don't tell me what to do!" The blond yelled.
"Deku-kun?" Uraraka pointed at the green haired boy with a shocked look and then turned to the blonde. "Bakugo-kun? And..." she lastly turned to the teary-eyed brunette. "Tsuna-kun?"
The two nodded in confirmation while the other glared. There was a moment of silence before Ashido broke it.
"Ohhh!" She exclaim in excitement. "Is that the afro kid's quirk?! Age regression?! What a impressive quirk!"
I don't think that's quite right but explaining it would be a pain, so I'm just going to let them think that it is... Tsuna thought in exasperation.
He still has a mind of a 14 year old even though his body is that of a 5 year old's. It was frustrating to say in the least because he remembered his 5 year old self being a big crybaby and thus he was unable to control his tear glands from producing the unneeded tears as he struggled to hold it in. It also didn't help that Bakugo's being terrifying and glowering menacingly at his 5 year old self.
To those who are familiar with the functions of the bazooka, obviously knew of the frequent malfunctions, courtesy of the self proclaimed #1 Vongola mechanic. He was always tinkering with things that doesn't need fixing and instead, made them worse than it originally was. Looks like instead of switching their bodies with their 10 year old self's, it turned their bodies back 10 years, making them too cute for their female classmates not to whip out their camera and snap tons of photos for future reference or in some of the guys' case—blackmail.
"You're soooo cute Bakugo-chan~ Maybe you should stay like this forever~" Kaminari teased, earning a deadly glare from the child, promising payback in the future—plus interest.
"Eh...Wha...what happened to my body?!" Midoriya finally realized what occurred to him and panicked, flailing his short arms in the air and making a lot of awkward movements. He wasn't used to his child body after all and kept tripping over his long pants that lingered behind him as he walked.
Despite the situation, Tsuna can't help but be amused as he watch on from the sidelines. The class was in chaos. Bakugo was yelling at Kaminari while Kirishima's tries to mediate between the two unsuccessfully, Midoriya was still panicking around the class as his two friends tries to calm him down and the rest of his classmates just stood there stupefied at what to do in this weird situation.
Welcome to my world. He dryly thought and chuckled to himself. He had to deal with these ridiculous situations all the time and if it was not resolve in time, another deadlier punishment awaits him in the hands of a demon spawn. He had no choice but to learn to deal with it—and quickly, I must add.
However, there were limits to what he could do in a 5 year old's body, including not being able to speak in proper, coherent sentences. He tried and kept stumbling over his pronunciations that made him sound like he's speaking gibberish, further embarrassing himself. Looks like this time he could only sit back and hopefully rely on his guardians to handle the matter till the bazooka effects time out.
He sighed deeply. Not liking this situation, not one bit at all.
While everyone was distracted with the 3 newly turned children, Lambo quietly sneak over and stash his bazooka away into his afro. But Gokudera swiftly caught the brat by his hair just as he was trying to make a quick retreat.
"Lambo! Did you let that quack mechanic touch your bazooka again!" Gokudera yelled at the cow.
"Lambo-san doesn't know anything! Lambo-san is innocent! Go to hell Baka-dera!" Lambo yelled and kicked him in the chin, forcing him to release his hold of him as he curses out loud. Lambo then proceeded to run away guiltily, proving to everyone that he did have something to do with the malfunctioning bazooka.
"Shit! Get back here Aho-shi!" Gokudera growled and ran out of the class after him.
"This is my chance to steal the bazooka!" Hatsume giggled and zoomed away on her specially made shoes.
"Ahaha...I'll go and make sure nothing happens." Yamamoto chuckled. "Don't worry Tsuna. I'm sure you'll be back to normal soon! Hang in there!" He gave an encouraging smile and proceeded to jog out after the three.
"What just happened?" Kaminari asked to no one in particular when the noise settled down.
Tsuna could only shake his oversize head in embarrassment. It's one thing these sort of crazy events happen in the Vongola mansion, but it's another when it happens here—at U.A! Tsuna could only hope that his Rain guardian could stop the Storm and the Lightning's childish game of Tag before they destroy something worth millions, or worse—something irreplaceable.
There was a moment of silence before Kaminari spoke up. "Hmm...Wasn't Todoroki-kun also hit by it?" Everyone perked up and turn their heads around eagerly to look for the heterochromic boy, exited to see how a 5 year old Todoroki would look like. But strangely, no one could find him, he wasn't in the class at all.
"Oh no! Could it be that he hasn't realize he's been turned into a child and went off for lunch?!" Kaminari exclaimed.
"It's possible." Asui agreed. "It's Todoroki-chan after all." Many others nodded their head in agreement.
Tsuna stared at his classmates in disbelief. Really? Who could be that dense?
"We have to go find him quick!" The 5 year old Deku exclaimed, his little face scrunch up in worry. The girls felt as though an arrow had just pierce through their hearts at how adorable their little green haired classmate looks and a few guys frowned as they felt a weird sensation tugging at their heartstrings.
"You should stay here Midoriya-chan. We'll find Todoroki and bring him back." Asui reassured the boy who looks like he's on the brink of tears.
"Just leave him to us Midoriya." Kaminari winked before heading out of the class with a few others in tow.
"Todoroki-kun!" They rushed out of the class in a hurry to find the dense boy before he gets himself in trouble.
Well...even more trouble than he already was.
