This is a proceedings for PPAP 2018. Thanks to speakers and participants, the workshop was timely and lively. The topics include Physics of Dark Matter, neutrinos and anti-neutrinos asymmetry, Non-abelian discrete symmetry as flavor symmetry, seesaw and CP violation, leptogenesis with gauged lepton number, search for Pseudo Nambu-Goldstone boson, particle number asymmetry, quantum entanglement, axion in hidden U(1), and CPT violation in neutrinos.
