The excited states of ${}_{\Lambda }^{25}$Mg with the $\Lambda$ hyperon in $p$ orbit are studied within the framework of the antisymmetrized molecular dynamics for hypernuclei. We obtained five rotational bands in ${}_{\Lambda }^{25}$Mg in which the $\Lambda$ hyperon in $p$ orbit is coupled to the ground and $K^{\pi }=2^{+}$ bands of ${}^{24}$Mg. We predict that the corresponding bands of ${}_{\Lambda }^{25}$Mg energetically split due to the triaxial deformation of the core nucleus ${}^{24}$Mg and the spatial anisotropy of the $p$ orbits of $\Lambda$.
