[Biroon Jr.] Replacing the Magical Girl

A cheerful magical girl finds her powers under threat when a creeping slime attempts to absorb her and steal her identity, her consciousness fading as her body swells into a soft, massively heavy form with enormous breasts. While a flawless clone takes her wand and slips perfectly into her role to deceive her fellow magical girls, the original is left humiliated, chained and bloated, insisting she is not with the monster as the impostor declares her goal to eradicate all magical girls. With the slime's transformation complete and the replacement ready to fool everyone, the humiliating body swap leaves the real heroine desperate to be recognized before she is erased entirely.
