Abstract	We present the preliminary Monte Carlo (MC) study of the B^+- -> D^0 (K_S pi^+pi^-)K^+- to extract phi_3 at the Belle II along. We discuss here the improvement in phi_3 measurement one may expect at Belle II with 50 ab^-1. We also present preliminary reconstruction of the K_S and D^0 ->K_Spi^+pi^- using the Phase II data and compared with MC.
