Renowned detective and sorcerer in training. Mystery tends to keep to herself, save for a select few of people.
She can come off as cold and calculated, especially to those she’s interrogating but lets go of that act a bit when around her friends. She’s actually pretty snarky and caring with a very sharp tongue. Despite this, it takes a LOT of time to earn her trust. Trust issues will do that, you know?
In fact, the reason she has those sunglasses on is because she strictly forbids anyone from seeing her eyes. Only those that she trusts with all her heart can see them. Heck, as of now the only person to see them is Serenity.
Much like her best friends, she is very determined and highly values the truth. When the chips are down, she’ll uncover the truth and see it through with her own two eyes.

Powers: She can not only summon ghost fists to fight, act as a barrier, and levitate her, but she can also access minds. This is her Act 3!
The way it works is that she can ask someone a series of questions and even if they want to lie, she’ll be able to tell and force the truth out of them. They don’t even realize they’re telling the truth either! It’s as if Mystery forces it out of them.
The only way Mystery can perform this however is if the person she’s interrogating feels both physically and emotionally cornered. (This is similar to how Psyche Locks work in Ace Attorney, but with the criteria mentioned before.)
