How do I unlock rank 4 parts for the Turn A Gundam?
Unlock and clear the “Moonlight Butterfly vs. Wings of Fire” Extra Mission. To unlock the mission, you must clear both “Operation Return to Earth” Friendship Missions and read the terminal message received afterwards that allows you to leave Dianna Counter. To play the Extra Mission, you also need to max out your relationship with both Loran Cehack and Gym Ghingham.
