  In this talk I summarize main features of the vector manifestation (VM) which
was recently proposed as a novel manifestation of the Wigner realization of
chiral symmetry in which the symmetry is restored at the critical point by the
massless degenerate pion (and its flavor partners) and the rho meson (and its
flavor partners) as the chiral partner. I show how the VM is formulated in the
effective field theory of QCD based on the hidden local symmetry and realized
in the large flavor QCD as well as in hot and/or dense QCD.
