We present the nucleosynthetic yields of Population III core-collapse supernovae (SNe) focusing on the cases of hyper-energetic (Hypernovae, HNe and hyper-aspherical (jet-induced) explosions. We show that (1) the explosions with large energy deposition rate, E-dep, are observed as GRB-HNe and their yields can explain the abundances of normal extremely metal-poor (EMP) stars, and (2) the explosions with small E-dep are observed as GRBs without bright SNe and can be responsible for the formation of the C-rich ENT (CEMP) and the hyper metal-poor (HMP) stars. We thus propose that GRB-HNe and the Non-SN GRBs (dark hypernovae) belong to a continuous series of BH-forming massive stellar deaths with the relativistic jets of different E-dep. We also show that the very peculiar Si-poor abundance can also be explained by the angle-delimited yield of aspherical explosion.
