  We show that the massless form fields, in $(4+1)$-dimensional
non-perturbation theory of emergent gravity, become massive in a perturbative
phase without Higgs mechanism. In particular an axionic scalar sourced by a
non-perturbative dynamical correction is absorbed by the form fields to
describe a massive NS field theory on an emergent gravitational pair of
$(3{\bar 3})$-brane. Arguably the novel idea of Higgs mechanism is naturally
invoked in an emergent gravity underlying a ${\rm CFT}_6$. Analysis reveals
"gravito-weak" and "electro-weak" phases respectively on a vacuum pair in
$(4+1)$ and $(3+1)$-dimensions. It is argued that the massive NS field quanta
may govern an emergent graviton on a gravitational $3$-brane.
