Morphology
like + a + demon
The simile marker 'like' plus 'demon' yields a manner comparison ("in the manner of a demon"), so the phrase conveys intense, relentless energy as a metaphorical extension of the noun. This is not purely compositional: the intensified, idiomatic sense relies on recognizing the cultural/metaphorical use of 'demon', so a B1 learner who only knows the literal words may not reliably infer the exact meaning without prior exposure.
Etymology
Like a demon comes from the old image of a demon giving a person wild, extra energy, as if they were driven to move very fast. So, to do something like a demon means to do it with 'great energy' or 'strong determination'.
