[en] Among the diversity of the connection between the long Gamma Ray Bursts (GRBs) and Supernovae (SNe), we present the models for the following two cases. (a) XRF-SN: we estimate the mass of the progenitor of SN 2006aj associated with X-Ray Flash 060218 is small enough to form a neutron star rather than a black hole, (b) Non-SN GRB: Two nearby long GRBs were not associated with SNe. Such 'dark HNe' have been predicted in order to explain the origin of C-rich (hyper) metal-poor stars. We will show our attempt to explain the diversity in a unified manner with the jet-induced explosion model. (author)
