In every main series Ace Attorney game with the exception of the first game, Phoenix Wright: Ace Attorney, Phoenix has a magatama item. This magatama was gifted to him by Maya Fey, and Pearl Fey put spiritual power into it. When charged up, this item allows Phoenix to see what people are hiding by breaking various locks that appear. Name every Psyche-Lock topic in the Ace Attorney series. Note that number refers to the number of Psyche-Locks there are.
Both red and black variations are included, although there are only two instances of black Psyche-Locks appearing.
Even if the locks are never broken, the topic will be here. Also, one specific answer has a star symbol in the middle of it, but just ignore it.
