Phoenix Wright continuity

Miles Edgeworth is now Chief Prosecutor in Los Angeles.

Franziska von Karma spends most of her time overseas working with Interpol, and while she feels the loss of ceding that high position to Miles, she enjoys the travel and challenges far more. She actually knows more about diverse legal systems that he does thanks to this. von Karma has a history with Sakura April, as she had chased the killer android for years when Sakura April was acting as an assassin--but Sakura April actually deflected a bullet of Shelly DeKiller's meant to kill one of the agents von Karma was working with, saving him, and thus von Karma has left her alone.

Godot is reinstated as a prosecutor and occupies the prestige position Miles Edgeworth once held in the day to day prosecutorial arena.

Klavier Gavin is once again touring with the Gavinners in between handling cases.

Mia Fey was resurrected and works alongside Phoenix Wright and Apollo Justice in the revived Wright and Co. Law Firm.

Detective Ema Skye has spent some time freelancing with Torchwood in America (after the events of Miracle Day, in which she ran across Captain Jack Harkness. So she's more familiar with the oddness that surrounds a place like Ten'ou House.
