  In this paper we analyse the Bianchi IX Universe dynamics within the corner
region associated to the potential term which the spatial curvature induces in
the Minisuperspace. The study is done in the vacuum and in the presence of a
massless scalar field $\phi$ and a cosmological constant term $\Lambda$. We
investigate the dynamics in terms of WKB scenario for which the isotropic
Misner variables (the volume) and one of the two anisotropic ones (and $\phi$
when present) are treated on a semi-classical level, while the remaining
anisotropy degree of freedom, the one trapped in the corner, is described on a
pure quantum level. The quantum dynamics always reduces to the one of a
time-dependent Schr\"{o}edinger equation for a harmonic potential with a time
dependent frequency. The vacuum case is treated in the limits of a collpasing
and an expanding Universe, while the dynamics in presence of $\phi$ and
$\Lambda$ is studied for $t \rightarrow \infty $. In both analysis the quantum
dynamics of the anisotropy variable is associated to a decaying standard
deviation of its probability density, corresponding to a suppression of the
quantum anisotropy associated. In the vacuum case, the corner configuration
becomes an attractor for the dynamics and the evolution resembles that one of a
Taub cosmology in the limit of a non-singular initial Universe. This suggests
that if the Bianchi dynamics enters enough the potential corner then the
initial singularity is removed and a Taub picture emerges. The case when $\phi$
is present well mimics the De-Sitter phase of an inflationary Universe. Here we
show that both the classical and quantum anisotropies are exponentially
suppressed, so that the resulting dynamics corresponds to an isotropic closed
Robertson-Walker geometry.
