  We prove the local-in-time well-posedness of the relativistic
Vlasov-Maxwell-Landau system in a bounded domain $\Omega$ with the specular
reflection condition. Our result covers the case when $\Omega$ is a non-convex
domain, e.g., solid torus. To the best of our knowledge, this is the first
local well-posedness result for a nonlinear kinetic model with a
self-consistent magnetic effect in a three-dimensional $\textbf{bounded}$
domain.
