Hayabusa2 spacecraft returned samples from near-Earth C-type asteroid 162173 Ryugu to the Earth on 6 Dec. 2020. Since the samples had been returned, we continue describing individual Ryugu particles for their images, weights, visible and infrared spectra with an optical microscope, a balance, a monochronic digital microscope with six-bands filters for incident light, an FT-IR and the infrared microscope MicrOmega. So far, 404 individual Ryugu particles have been handpicked and described.
