The spectra of several galaxies, including extremely metal-poor galaxies(EMPGs) from the EMPRESS survey, have shown that the abundances of someSi-group elements differ from "spherical" explosion models of massive stars.This leads to the speculation that these galaxies have experienced supernovaexplosions with high asphericity, where mixing and fallback of the inner ejectawith the outer material leads to the distinctive chemical compositions. In thisarticle, we consider the jet-driven supernova models by direct two-dimensionalhydrodynamics simulations using progenitors about 20 -- 25 $M_{\odot}$ at zerometallicity. We investigate how the abundance patterns depend on the progenitormass, mass cut and the asphericity of the explosion. We compare the observablewith available supernova and galaxy catalogs based on $^{56}$Ni, ejecta mass,and individual element ratios. The proximity of our results with theobservational data signifies the importance of aspherical supernova explosionsin chemical evolution of these galaxies. Our models will provide thetheoretical counterpart for understanding the chemical abundances of high-zgalaxies measured by the James Webb Space Telescope.
