The Last of 1-A to fall

"Just a... few more..." Mt Lady begins to moan as she grinds herself into Mina, pushing the girl into the wall with surprising strength. She tries to extend her arms to shove the hero off her, but fails to make her budge.

"Mt Lady- Please-" She looks around for anyone to help her, but as the night continues on, the streets have grown empty. She's completely alone...

With one last attempt to escape, Mina creates a wall of acid in between her and her assailant. But her grasp on the girl is strong and resists through the slippery substance. All the acid manages to do is melt at Mt Lady's spandex outfit, revealing her enlarged breasts to the girl.

Her pale breasts with darkened nipples are a telltale sign something has changed the hero. She smooshes herself into Mina as she bares her fangs. A low hiss can be heard before complete silence.

The street is devoid of any noise at all as the two grow silent. Mina stares off into space as she feels two knives pierce her neck. She can feel the contents of her body draining as Mt Lady indulges in her impossibly strong desires. It isn't until someone turns a nearby corner and gasps that she lets go, dropping Mina to the ground.

For a moment, after swallowing the last bit of blood in her mouth, Mt Lady gains a moment of clarity. She looks at the girl on the ground, then back to the shocked stranger. "Wha- What just happened?" She feels her frenzied state of being fade, her lust reducing down to what is considered average for a fledgling. "Mina... Are you okay?"

The moment she's free to move, Mina uses her quirk and jumps up to her feet, generating acid from her feet as she slides away. "No no no no! I need to- I need help!" She holds her neck and feels blood spilling over her hand. As she makes her way down the street she can feel the holes slowly heal themselves, something that can only mean trouble.

Once they seal completely, Mina begins to feel something strange. Her energy begins to sap from her body as she drops her arms. Luckily skating in this manner doesn't take much effort, and she continues her escape from Mt Lady. Soon she finds herself outside the city and back onto the dark road she ran down earlier in the night, she pants and clenches her teeth as a warmth begins to spread from her stomach.

"No... I can- I can fight this..."

The usually energetic tomboy of class 1-A resists as hard as she can. But it's no use. Her pink skin, the iconic signature of the girl, begins to pale. She continues skating down the road, albeit more lazily than normal as her body is molded by the gift from Mt Lady. Her average breasts strain her UA uniform as they bubble outward. She feels her balance begin to shift as her waist cinches in slightly.

Her ass gains new dimensions to complete her new physique, giving her all the tools she needs to help with attracting a mate. She pants as her ears lengthen and her eyes shift. The black sclera in her eyes remain while her yellow irises change to a dark red. Her small horns on her head change as well, the corruption changing them to more resemble traditional succubus horns as they straighten out a bit and grow darker. She feels her knees tremble before falling to the pavement, her new fangs forcing their way into her mouth to complete her transformation.

With the completion of her transformation, the last female student of class 1-A falls and begins her path to eternal life.

Mina groans and looks up, noticing something downright horrifying. In her panicked state, she just ran away from Mt Lady, not realizing that she was skating back the way she came. She can see the light from the UA dorms in the distance, sounds of ecstasy coming from within.
