%X We present a measurement of the time-dependent CP asymmetry in B<sup>0</sup> → K<sub>S</sub><sup>0</sup>  π<sup>+</sup> π<sup>−</sup> γ decays using a data set of 365 fb<sup>−1</sup> recorded by the Belle II experiment and the final data set of 711 fb<sup>−1</sup> recorded by the Belle experiment at the Υ(4S) resonance. The direct and mixing-induced time-dependent CP violation parameters C and S are determined along with two additional quantities, S<sup>+</sup> and S<sup>−</sup>, defined in the two halves of the m<sup>2</sup>(K<sub>S</sub><sup>0</sup> π<sup>+</sup>)−m<sup>2</sup>(K<sub>S</sub><sup>0</sup> π<sup>−</sup>) plane. The measured values are C = −0.17 ±0.09 ±0.04, S = −0.29 ±0.11 ±0.05, S<sup>+</sup> = −0.57 ±0.23 ±0.10 and S<sup>−</sup> = 0.31 ±0.24 ±0.05, where the first uncertainty is statistical and the second systematic.
