Kodai and Jiro

While those around them fall, one surprising sanctuary remains. The 1-B dorms for UA High has yet to house even a single fledgling up until now. Everything is as it should be, until a sudden surprise shocks everyone.

The class of students casually sits around watching a movie. With most of them present, the bundle up with eachother under blankets for a wholesome night in. But at the most unexpected moment, one of them falls forward onto the ground.

Yui Kodai groans as she hits the floor. A sudden wave of vertigo hitting her body, causing her to feel faint. She almost loses consciousness, but eventually feels her strength returning. Her classmates crowd around her, but given her quiet and reserved nature, she doesn't respond to any of them.

Eventually she raises her head, looking around the room with new vision. "Everything's... Brighter?" She asks herself quietly. A pleasant heat radiates from her nether regions, alerting her to a new path.

"Are you okay Kodai?" Itsuka Kendo uses her quirk to expand her hands and move everyone out of the way, giving the new fledgling room to breathe.

Kodai sits for a moment before giving a slight smile. A warm buzz soothes her brain, making her feel good. "Yeah... I'm okay."

While the previously untouched dorm building begins to house its first vampire. A nearby building full of them comes closer to total nirvana. Another orgy in the 1-A common area breaks out as every human student falls to the ground. The vampires in charge had made sure to taint every last one of them, and they all watch their classmates join them with glee. Though all the humans fall, two already tainted students follow suit.

Jiro and Kaminari, the perverted lovers. They'd been with eachother all day, and in the process furthered eachother along. Jiro moans and grips the carpet, using her hand to rub her pussy as she transforms for the final time. Already completely devoted to the cause, she welcomes it with open arms.

The voice of her Master grows louder along with her strength. She rubs faster, bringing herself to an otherworldly orgasm, enhanced by her increasing sensitivity. "Fffuuuccckk yyyeeeesssss~~" She cums hard, her mind going blank as the hole where her soul used to be begs to be filled.

After the orgasm fades, the goth girl licks her lips and stands up with a devious smile. Her scream had silenced the entire room, causing them to all look at her in awe.

She blushes, noticing everyone's new looks as fledglings. "Fuck, you all look so..." She's interrupted by a hand grabbing hers. Turning to look, she's met with the chiseled face of Kaminari, now a level 2 fledgling.

She's stunned for a moment, but soon leaps into him, planting herself on his monster cock. This immediately Kickstarts the true orgy of class 1-A, this time involving every last student...
