Achieving successful leptogenesis in the $U(1)_{L_{\\mu}-L_{\\tau}}$ symmetric phase is challenging due to the absence of a CP phase, caused by restriction from the gauge symmetry. To overcome this issue, we introduce an additional global symmetry, $U(1)_{B-L}$, and a scalar field $\\Phi$ responsible for breaking this symmetry. Through the kinetic misalignment mechanism, the majoron field associated with $U(1)_{B-L}$ symmetry breaking has a kinetic motion in the early universe.
