I'm sure Elektro kinda spelled that out. From what I can wrap my brain around after doing a little extra RWBY research, semblances are supposed to be like a manipulation of natural phenomenon. Thats what this does, it changes the atomic make-up (Proper wording?) of her body, thereby making it softer or harder than the average human body. Also, Yin doesn't need to protect her organs because they will also become... become... GOD DAMN IT! I know theres a proper word for this. It can't be density. Whatever. When her body becomes soft, I mean everything becomes soft. The only problem is what Elektro pointed out about her lungs and bowels. Though those would be a case of MST3K mantra or assumed "Required secondary Powers" since I still can't think of a proper explanation.

Also, after reading your comment, and writing that paragraph, I realized that technically the Soft/ Hard semblance is not allowing Yin to do multiple things, but rather a single thing. Changing the toughness of her body into whether it has soft or hard is one thing. It isn't like shes litterally changes into a rock or a piece of cotton. That would be a case of a multi-ability semblance. Kinda like how Weiss's semblance affects motion, I think. Stop motion, increase jumping motion, launch motion, and speed motion. It has the appearance of doing multiple things, but in actuallity it's only affecting a single thing.

Also, that last part about Weiss I just realized litterally seconds ago.
