  We predict a new three-body hadronic molecule composed of antikaon $\bar{K}$,
anticharm meson $\bar{D}$, and nucleon $N$ with spin/parity $J^{P} = 1/2^{+}$
and isospin $I = 1/2$. This state behaves like an explicit pentaquark state
because its minimal quark configuration is $u u d s \bar{c}$ or $u d d s
\bar{c}$. Owing to the attraction between every pair of two hadrons, in
particular the $\bar{K}\bar{D}$ attraction which dynamically generates $D_{s 0}
(2317)^{-}$ and $\bar{K} N$ attraction which dynamically generates $\Lambda
(1405)$, the $\bar{K}\bar{D} N$ system is bound, and its eigenenergy is
calculated as $3244 - 17 i$ MeV in a nonrelativistic three-body potential
model. We discuss properties of this $\bar{K} \bar{D} N$ quasibound state which
emerge uniquely in three-body dynamics.
