  Let $N$ be a normal subgroup of a finite group $G$ and let $H/N$ be a normal
$p$-subgroup of $G/N,$ where $p$ is a prime. Let $\theta$ be an $H$-invariant
$p$-defect zero irreducible Brauer character of $N.$ Let $D$ be a defect group
of the unique block of $H$ covering $\theta$ and let $M={\rm N}_G(D).$ Let
$\theta^{\star_{D}}$ be the DGN correspondent of $\theta$ with respect of $D.$
Suppose that $^{g}\theta$ is Galois conjugate to $\theta$ for any $g\in G.$
Then we prove that there exists a well behaved bijection from the set of
irreducible Brauer characters of subgroups of $G$ that covering a
$G$-conjugation of $\theta$ to the set of irreducible Brauer characters of
subgroups of $M$ that covering a $M$-conjugation of $\theta^{\star_D}.$ This
bijection of irreducible Brauer characters commutes with Galois action and
$G$-action, and is compatible with restriction and keeps the vertex.
