That depends on your definition of "good".

If by "good" you mean "a hero/heroine", then yes. Tsubaki broke the Mind Eater curse and now joins the heroes' fight to save the world. In fact, she's so dead set on fighting for justice that she sticks by Hakumen for the majority of Central Fiction.

If by "good" you mean "on the main character's side", then no. Tsubaki, despite breaking Mind Eater, still sees Ragna as a greater evil than Terumi and Izanami combined. Between Jin's initial insanity and Hakumen's bitter rivalry, the Izayoi and Wheel of Fortune have convinced Tsubaki that Ragna is quite literally the root and stem of all evil.

Either way you slice it, it's part of the whole "see my own justice" thing, and she REALLY needs to learn her place.
