  In this paper, we propose a general scheme to realize chiral TSCs through the
"twistronics". Suppose we have a $D_n$-symmetric monolayer superconductor,
which carries non-topological SC with pairing angular momentum $L=n/2$. Here we
propose that we can obtain chiral TSC with the same $L$, by stacking two such
monolayers with the largest twist angle $\pi/n$, forming a Moireless
quasi-crystal (QC) structure, dubbed as the twist-bilayer QC (TB-QC) here. The
chiral TSC in the TB-QC is driven by the interlay Josephson coupling between
the pairing order parameters of the two layers. An argument based on the
universal Ginzburg-Landau theory is provided to understand this proposal. One
known example which fits our proposal is the $d+id$-chiral TSC in the
45$^\circ$-twisted bilayer cuprates. Here, based on the microscopic framework
developed previously to treat with the electron-electron interactions in the
TB-QC, we demonstrate the application of our proposal to a new example, i.e.,
the $f+if$-chiral TSC obtained by twisting two properly-doped
honeycomb-Hubbard-model monolayers by the angle 30$^\circ$. This example is
related to the newly synthesized 30$^\circ$-twisted bilayer graphene.
