In this paper, we consider the chemotaxis-Navier-Stokes system with nonlinear diffusion and rotational flux given by
 $\begin{eqnarray*} \left\{\begin{array}{lll}n_{t}+u\cdot\nabla n=\Delta n^m-\nabla\cdot(uS(x,n,c)\cdot\nabla c),&x\in\Omega,\ \ t>0,\\[1mm]c_t+u\cdot\nabla c=\Delta c-c+n,&x\in\Omega,\ \ t>0,\\[1mm]u_t+k(u\cdot\nabla)u=\Delta u+\nabla P+n\nabla\phi,&x\in\Omega,\ \ t>0\\[1mm]\nabla\cdot u=0,&x\in\Omega,\ \ t>0 \end{array}\right.\end{eqnarray*}$
in a bounded domain
 $\Omega\subset\mathbb{R}^3$
, where
 $k\in\mathbb{R}$
,
 $\phi\in W^{2,\infty}(\Omega)$
and the given tensor-valued function
 $S$
:
 $\overline\Omega\times[0,\infty)^2\rightarrow\mathbb{R}^{3\times 3}$
satisfies
 $|S(x,n,c)|\leq S_0(n+1)^{-\alpha}\ \ {\rm for\ all}\ x\in\mathbb{R}^3,\ n\geq0,\ c\geq0.$
Imposing no restriction on the size of the initial data, we establish the global existence of a very weak solution while assuming
 $m+\alpha>\frac{4}{3}$
and
 $m>\frac{1}{3}$
.
