I already laughed at just the summary.

This was absolutely hilarious. I really like how you gave them each their own personality. It would be nice to even see how this trial ends up in a sequel or continuation (I'm guessing a not guilty just because Misty takes after Phoenix, and most of Phoenix's trials end in a not guilty).

This may be a bit of a late review, but I loved this story! These girls are definitely Phoenix and Maya's children- especially Misty, who has taken her father's techniques to a whole new level by swinging wildly without any regard to who she takes down in the process. Though Phoenix and Maya should both sleep with one eye open when Mercy's around since it seems like she inherited a bit of her Aunt Morgan's personality.
I would love to be a fly on the wall when Edgeworth has that talk with Mia after the trial. I could imagine our favorite demon prosecutor saying something along the lines of, "Excellent job with that updated autopsy report, Mia. It pleases me to see that you're taking my methods to heart. However, how you dealt with Miranda was much to be desired. I know that she is your sister, but you have to assert your authority. That's why the next time she does something so out of line, you give her the ol' one, two, pay cut. For not only will it show Miranda who's boss and help to reduce the occurrence of these kinds of incidents, but when you actually reward her, she'll be so grateful that she'll follow you to the ends of the earth."
Once again, this was a really fun story to read! I'm looking forward for what else you have planned!

I'd like to say this would never happen. But in the world of Ace Attorney, the prosecutor, the defense attorney, the judge, and the detective being quadruplets seems like one of the least weird things that could happen.

I smell a spin-off series!
Seriously though, this was too damn adorable. I loved it!
