After a very brief review about the current constraint on the equation of the state of the dark energy from the SN and a new scenario of dark energy {\it the Quintom}, I present models of Quintessential Baryo(Lepto)genesis, Quintessino dark matter and mass varying neutrinos in details.Plenary talk at "SUSY2004", Tsukuba, Japan, June 2004: LaTeX with pdproc.sty (included), 13pagesHigh Energy Physics - PhenomenologyAstrophysicsGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
