  We present measurements of CP-violation parameters in b -> s gamma
transitions based on a sample of 386x10^6 BB pairs collected at the Y(4S)
resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider.
One neutral B meson is fully reconstructed in the B0 -> Ks Pi0 gamma decay
channel irrespective to the Ks Pi0 intermediate state. The flavor of the
accompanying B meson is identified from its decay products. CP-violation
parameters are obtained from the asymmetries in the distributions of the
proper-time intervals between the two B decays.
  We obtain the following results for the Ks Pi0 invariant mass covering the
full range up to 1.8 GeV/c^2: S_{Ks Pi0 gamma} = +0.08 +-0.41(stat)
+-0.10(syst), A_{Ks Pi0 gamma} = +0.12 +-0.27(stat) +-0.10(syst).
