To investigate the case that tidal disruption takes place, we choose the initial mass of the black hole to be $5.4M_\\odot$ or $8.1M_\\odot$ with the dimensionless spin of 0.75. The neutron-star mass is fixed to be $1.35M_\\odot$. We find that after the tidal disruption, dynamical mass ejection takes place spending $\\lesssim 10$ ms together with the formation of a massive accretion disk.
