  We present a comprehensive analysis of the multi-phase structure of the
interstellar medium (ISM) and the stellar kinematics in the edge-on nearby
galaxy UGC 10205 using integral field spectroscopy (IFS) data taken with MEGARA
at the GTC. We explore both the neutral and the ionized gas phases using the
interstellar Na ${\small I}$ D doublet absorption (LR$-$V set-up, R $\sim$
6000) and the H$\alpha$ emission line (HR$-$R set-up, R $\sim$ 18000),
respectively. The high-resolution data show the complexity of the H$\alpha$
emission line profile revealing the detection of up to three kinematically
distinct gaseous components. Despite of this fact, a thin disk model is able to
reproduce the bulk of the ionized gas motions in the central regions of UGC
10205. The use of asymmetric drift corrections is needed to reconciliate the
ionized and the stellar velocity rotation curves. We also report the detection
of outflowing neutral gas material blueshifted by $\sim$ 87 km s$^{-1}$. The
main physical properties that describe the observed outflow are a total mass
M$_{out}$ $=$ (4.55 $\pm$ 0.06) $\times$ 10$^{7}$ M$_{\odot}$ and a cold gas
mass outflow rate $\dot{M}$$_{out}$ $=$ 0.78 $\pm$ 0.03 M$_{\odot}$ yr$^{-1}$.
This work points out the necessity of exploiting high-resolution IFS data to
understand the multi-phase components of the ISM and the multiple kinematical
components in the central regions of nearby galaxies.
