In-plane magnetoresistance for organic massless Dirac electron system (OMDES) α-(BEDT-TTF)₂I₃and θ-(BEDTTTF) ₂I₃in addition to possible candidates of the OMDES α-(BETS)₂I₃and α-(BEDT-STF)₂I₃, was investigated under hydrostatic pressure. We have found the universal behavior of the in-plane magnetoresistance under a low magnetic field perpendicular to two-dimensional plane. As for α-(BEDT-TTF)₂I₃, the universality was examined with the parameters of temperature, magnetic field and its direction. We suggest that the universal magnetoresistance behavior is found even for the gapped state of α-(BEDT-TTF)₂I₃under intermediate pressure, when the thermal energy exceeds the gap.
