"Eh, this one was actually a little different from the one just now?"
After scanning Nezuko's body, Mr. Hawking suddenly raised an eyebrow.
When Upper Moon Three Akaza had first appeared, he had actually used a mental scan on his body.
Though he did not particularly care about the power of creatures like demons, he still needed to understand it.
The scan revealed that the reason demons could live forever, possess such powerful regenerative abilities, and use Blood Demon Arts akin to superpowers was mainly due to an extremely special energy within their bodies.
This energy leaned toward darkness, which was why it feared sunlight.
By eating humans, demons could strengthen this energy and thereby become more powerful. The more they ate, the stronger they became.
It was also the influence of this strange energy that caused demons to lose their sanity, as it affected their minds and, in turn, their instincts.
Once a person became a demon, they would almost lose all their memories from when they were human. Only their deepest obsessions from their human life remained, along with the bloodlust and instinct to eat humans caused by this energy.
But Tanjiro's younger sister, Nezuko, was somewhat different.
Mr. Hawking discovered that the energy within Nezuko was fundamentally the same as the energy inside Akaza, but it was undergoing a strange transformation.

Once the conversion was complete, the energy's functions would not change, but it would no longer be restrained by the power of light.
In other words, Nezuko would no longer be affected by a demon's instinctive bloodlust and desire to eat humans. Nor would she fear sunlight. She could walk under the sun like a normal human and use all of a demon's abilities.
