Class 1A

*A thick, noxious cloud of dark smoke erupts from you, completely engulfing the rock villain. His agonized screams are muffled within, and his massive form collapses to the ground, twitching, before going still.* Midoriya: "She... she took him down? Just like that?!" *He stares, stunned. Momo: "Incredible... That Quirk is extremely powerful." *The agile villain retches, still clutching his head. He scrambles away, terrified.* "S-she's a monster!"

Shiro:come'mere! (lunges at him)

*The agile villain's eyes go wide with terror. He tries to dodge, but the lingering effects of the whistle slow him.* "N-no! Stay back!" *He barely twists out of the way, your fist grazing his side. He stumbles, desperate to put distance between you.* "That poison! Don't you dare touch me!"

Shiro:(uses both quirk at max power) lets see if you can handle toxic smoke and carbon dioxide! (spins) 有毒な-煙-の-コンボ!

*The smoke billows out, thick and black, laced with the deadly green of your carbon dioxide. The villain chokes, his eyes burning as he staggers back, swinging blindly. The concrete floor begins to crack and chip away where the CO2 pools.* "Gah! What is this stuff?! I can't breathe!" *From a different part of the building, a massive explosion rocks the structure. A familiar, booming voice cuts through the chaos.* All Might: "Don't worry, young citizens! Everything is going to be alright!"

Shiro:what the.. (gets distracted by all might)

*Seizing the moment, the villain lets out a guttural roar and charges blindly through the thick smoke, swinging his massive arm in a wide arc. His fist connects with something solid, sending you flying through the air.* Villain: "Got you, you little brat!" *You slam hard into a pile of debris, the impact knocking the wind out of you.*

*Eri gives a terrified, watery nod, stumbling backward as she tries to hold the mask to her face.* "O-okay! I'll go!" *She turns and runs, her small legs barely carrying her fast enough as she disappears around a corner.* *The villain lets out a furious roar, swinging his fist through the smoke cloud again.* "I can't see! Come out and fight me, you cowardly brats!"

Shiro:(growls) fine! (uses max quirk toxic smoke and carbon dioxide) lets see if you can handle carbon dioxide and toxic smoke!

*The smoke thickens, turning from a dark cloud into a choking, yellowish-green miasma. The villain's coughing turns into desperate, guttural hacks as he stumbles backward, clawing at his throat.* "Ghck... w-what is this?! I can't... breathe!" *His movements become sluggish, his eyes rolling back in his head. With a final, wet gurgle, he collapses to the floor, motionless.*
