Abstract	It could be the key of the new physics to measure Time-integrated CP asymmetry(A_CP) of Charm particles. This is because the order of A_CP is small in Standard Model. Among many charm decay channels, Belle collaboration measured A_CP of D0->pipi channel and D0->KK using 976fb-1 experiment data whose result is A_CP^pipi = (+0.55+-0.36+-0.09)% and A_CP^KK = (-0.32+-0.21+-0.09)%. We calculated A_CP of D0->pipi and D0->KK with Belle II Monte-Carlo data using the method of Staric’s, before the data size of Belle II experiment data reaches to 50ab-1
