Morumo 1/10

A high school couple discovers a baby girl inside what appears to be a fallen meteorite and adopt her, naming her Morumo. As a freshman, she is 16.4 meters tall but lives a relatively normal life, attending school and being well-liked by the community. A scientist, known for targeting young women in his experiments, gives Morumo a serum that shrinks her to one-tenth her size without reducing her weight, making her extremely dense and strong. The change allows her to experience a more typical lifestyle briefly, but the effect is not permanent. After returning to her original size, Morumo remains determined to find a lasting solution. She and her friend Miharu consider allowing further experiments by the scientist, believing the potential for a normal life justifies the risk.
