On the basis of the Ginzburg-Landau free energy with QCD symmetry, the interplay between the chiral and diquark condensates is investigated. We demonstrate that the axial anomaly drives a new critical point in the phase diagram and leads to a smooth crossover between the hadronic and color superconducting phases. We also discuss the continuity of these phases in the excited states.
