We propose a unified setup for the cosmological issues such as inflation and reheating, dark matter, and baryon-number asymmetry through the neutrino mass seesaw mechanism. Our scenario emerges naturally from a gauge group that contains B - L as a non-commutative symmetry, broken by a scalar that drives inflation. Its decays to right-handed neutrinos or Higgs fields reheat the universe. Automatic matter parity conservation stabilizes asymmetric dark matter candidates directly linked to the matter-antimater asymmetry of the universe.
