  We present a new mechanism to relax the initial misalignment angle of the QCD
axion and raise the cosmological bound on the axion decay constant. The QCD
axion receives a contribution from small UV instantons during inflation, which
raises its mass to the inflationary Hubble scale. This makes the axion start
rolling down its potential early on. In the scenario, the standard model Yukawa
couplings of quarks are dynamical, being of order one during the inflationary
era and reducing to their standard model values once it ends. This means that
after inflation the contribution of the small instantons is suppressed, and the
axion potential reduces to the standard one from the usual IR instantons. As a
result, when the axion starts to oscillate again after inflation, the initial
misalignment angle is suppressed due to the dynamics during inflation. While
the general idea of dynamical axion misalignment has been discussed in the
literature before, we present in detail the major bottleneck on the mismatching
between the minima of the axion potentials during and after inflation, and how
it is circumvented in our scenario via the Froggatt-Nielsen mechanism. Taking
into account of all the constraints, we find that the axion decay constant
could be raised to the GUT scale, $10^{15}$ GeV, in our scenario.
