Chapter 4: Blastey

Class 1-A was in the midst of Aizawa's lecture when the door burst open with a bang. In rushed Izuku Bakugou, her eyes sparkling with excitement. She grabbed Katsuki by the arm and pulled him along, completely disrupting the class.

Aizawa stopped mid-sentence, his eyes narrowing at the sudden interruption. "Bakugou, what is the meaning of this?"

Izuku grinned mischievously, unfazed by the stern gaze of their teacher. "Sorry, Aizawa-sensei! But I just couldn't wait to show everyone our new invention! It's gonna be epic!"

The class exchanged bewildered glances, unsure of what Izuku was talking about. Katsuki, however, wore a smirk, clearly aware of what his sister had in store. "Get ready, losers! Izuku and I are about to blow your minds!"

The confusion in the room only grew as Izuku pulled out Blastey, the magnificent weapon she had designed. It gleamed with power and potential, capturing everyone's attention.

"Whoa, what is that?" Kirishima exclaimed, his eyes widening.

"Izuku, is that your quirk?" Uraraka asked, her voice filled with surprise.

Izuku chuckled, shaking her head. "Nah, it's just a support item I created. But trust me, it's gonna pack a punch!"

Aizawa, still trying to regain control of the chaotic situation, sighed in exasperation. "Bakugou, your sister is causing a disturbance. This better be worth it."

Power Loader, unable to contain his excitement, stepped forward, a wide grin on his face. "Oh, it's more than worth it, Aizawa! This item is a masterpiece! You're in for a treat!"

Aizawa raised an eyebrow, looking at Power Loader sceptically. "I hope you know what you're doing."

Ignoring the teacher's concern, Power Loader turned to Izuku and Katsuki. "Alright, Explosive Siblings! Let's see what this baby can do! Show them the true meaning of power!"

Katsuki and Izuku exchanged knowing glances, their anticipation growing. They both donned their Blastey equipment, ready to unleash havoc upon the fake city.

As they stepped onto the fake City, the class watched in both awe and disbelief. The destruction was swift and merciless. Buildings crumbled, explosions rocked the air, and debris flew in all directions. The once pristine city was reduced to ruins in a matter of minutes.

"Is this even legal?" Momo muttered, her eyes wide with shock.

"I never thought Izuku could cause this much chaos!" Denki exclaimed, a mix of fear and excitement in his voice.

Aizawa and the other teachers stood at a distance, their mouths agape, unable to comprehend the sheer power of Blastey and the Explosive Siblings. Power Loader, on the other hand, couldn't contain his laughter, revelling in the chaos unfolding before him.

"Look at that destruction!" Power Loader cackled, pointing at the crumbling buildings. "That's the power of Blastey! Isn't it incredible?"

Aizawa sighed, pinching the bridge of his nose. "I suppose incredible is one way to describe it."

During the chaos, Izuku's voice could be heard, shouting with glee. "Blastey! Blastey!"

The class exchanged confused glances, struggling to comprehend the meaning behind Izuku's repeated exclamation. Only Katsuki, who had a front-row seat to his sister's enthusiasm, gasped as realization dawned upon him.

"Blastey... she named her invention Blastey!"

he exclaimed, a mix of disbelief and amusement in his voice.

The battle continued, explosions resonating through the air as Izuku and Katsuki revelled in the power of Blastey. The class watched, equal parts terrified and fascinated, as their classmates wreaked havoc on the fake city.

In the end, the Explosive Siblings stood amidst the destruction, their bodies covered in soot and grin plastered on their faces. Izuku ran up to Katsuki, unable to contain her excitement.

"Did you see that, Kat?! Blastey was amazing!" she exclaimed, her eyes shining with pride.

Katsuki pulled his sister into a tight hug, rubbing her back gently. "Yeah, Izuku. You did great. I missed this side of you."

As the smoke cleared and the chaos settled, the class finally found their voices.

"Is it too late to transfer to the support course?" Tsuyu muttered, her voice laced with both awe and terror.

"Izuku sure knows how to make an entrance," Mineta remarked, a bead of sweat rolling down his forehead.

Aizawa, although exhausted and slightly frustrated, couldn't help but feel a hint of pride for his students. "Well, at least they got the class excited about something."

The aftermath of the Battle of Blastey left Class 1-A and their teachers in awe and confusion, with Izuku and Katsuki's explosive partnership and the power of Blastey forever etched in their memories.
