Her fight with Makoto technically never happened due to a time-reset (thank you Amaterasu and Takamagahara), else Makoto would be dead by now.
Her fights with Hakumen and Mu takes place after she's been freed from the Imperator's control, though they do help in her decision on what she should fight for.
Also, Tsubaki's definition of justice hasn't really changed since being freed, she just now fights for her friends instead of the NOL (which she now considers unjust). Though she has taken to acting like a superhero, complete with hammy dialogue about "JUSTICE JUSTICE JUSTICE".
