Query: Current signatures and search for Pop. III stars in the Local Universe   Recent numerical studies argue that low-mass stars can be formed even at
zero-metallicity environment. These low-mass Population III(Pop.~III) stars are
thought to be still shining and able to be observed in the Local Universe. Most
low-mass Pop.~III stars are thought to be formed as secondary companions in
binary systems. They can be escaped from their host mini-halos when their
primary companions explode as supernovae. In this paper, we estimate the escape
probability of the low-mass Pop.~III stars from their host mini-halos. We find
that $\sim 100$ Pop.~III stars are expected. We also compute spatial
distribution of these escaped Pop.~III survivors by means of the semi-analytic
hierarchical chemical evolution model. Typically, they are distributed around
$\sim 2$Mpc away from the Milky Way but 5 -- $35\%$ of the escaped stars fall
into the Milky Way halo. These escaped Pop.~III stars are possibly detected by
very large scaled surveys being planned.
