Outgrowing only girls, Overtake boys, Growth sound. VRroom Arc

A “sound that activates the human body,” secretly developed, was being woven into the daily school broadcast. This mysterious resonance would soon shatter the ordinary peace of school life—and more than anything, transform the girls’ bodies from their very foundations.

The stage of the story is the enigmatic “VR Room,” a facility capable of materializing anything and measuring personal body data with perfect accuracy. At first, the changes were small. But beginning at just 140 cm on Day 1, the girls’ heights began to climb at an unbelievable rate with each passing day.

Astonishingly, this phenomenon appeared only in girls. The boys’ heights remained completely unchanged. The VR Room documented, with merciless precision, the process as the girls surpassed the boys, growing taller and taller until they became towering giants, gazing down from far above.

Not only height, but inseam length was also numerically revealed, confronting the boys with the overwhelming difference in leg length. Soon, the girls gained incredible physical strength, easily lifting boys into the air. Ceilings designed for the boys’ heights were effortlessly pierced by the girls’ heads. In races, the boys were left behind in an instant as the girls reached the finish line. Ultimately, the girls’ legs grew longer than the boys’ entire bodies—the ultimate transformation.

Everyday life crumbled. The boys found themselves swallowed by the shadows of the ever-growing girls, left only with shock, confusion, and an unbearable sense of inferiority.

This is a story for those who love growth: the ultimate tale of bodily transformation, where girls’ astonishing evolution is set against the diminishing presence of boys. And the girls’ growth is far from over—step inside, and experience this overwhelming world yourself.
