This is motivated by the increasing interest in the QCD phase diagram as follows: ( 1) The QCD critical point search has been under intensive dispute and its location and existence suffer from uncertainty of effective U(1)(A) symmetry restoration. ( 2) A new phase called quarkyonic matter is drawing theoretical and experimental attention but it is not clear whether it can coexist with diquark condensation. We point out that two-color QCD is nontrivial enough to contain essential ingredients for ( 1) and ( 2) both, and most importantly, is a system without the sign problem in numerical simulations on the lattice. We adopt the two-flavor Nambu-Jona-Lasinio model extended with the two-color Polyakov loop and make quantitative predictions that can be tested by lattice simulations.
