You were in Nobara's room at the Jujutsu school. The young sorceress was excited, as she said she had acquired a new skill, and was dying to show it to you.

"Are you ready?", Nobara asked after placing you sitting on her bed facing her.

"Um... yes? I mean...", After giving your answer, and before you could comprehend what was happening, Nobara's hand made contact with her chest. A shiver ran through her body as she let out a mischievous moan, and then... the world began to distort.

In an instant, you realized the inexplicable phenomenon unfolding before you – you were decreasing in size, while the young girl was becoming increasingly bigger, more muscular and curvaceous.

"YES!", The young girl screamed euphorically as she reached 30 feet tall, her uniform was in tatters, barely able to contain her new voluptuous curves and hard muscles., "Much better... now you!"

You notice that the giantess is focusing her attention on you with a mischievous look.
