  We consider an extension of the Standard Model by three singlet fermions and
one singlet real scalar field. The scalar is an ultralight dark matter
candidate whose abundance is set by dynamically induced misalignment from the
Higgs portal. We focus on parameter space where the Coleman-Weinberg potential
both fixes the dark matter relic abundance, and predicts the mass scale of
right-handed neutrinos. The model prefers scalar masses in the range of $10
~{\rm {\mu}eV} \lesssim m_{\phi} \lesssim 10 ~{\rm meV}$, and can be tested via
direct searches for a light scalar (e.g. fifth force tests), or by searching
for right-handed neutrinos in laboratory experiments.
