@True_Hero I highly doubt it, I'm pretty sure there are going to be an introduction to characters, but to be sure you don't miss this game (if localized, that's it) here:

Phoenix Wright is a defence attorney who pursues to prove his clients' innocence against the toughest odds — and the most ruthless adversaries.
The mousey girl, Maya Fey, seems to be his assistant, but in reality she is a medium-in-training, and a bit of a shady character...

Professor Hershel Layton is an top-hat wearing archaeologist who leaves no puzzles unsolved, he is renowned at London for his puzzle-solving skills.
Luke Triton is a inquisitive boy and Professor Layton's self-proclaimed apprentice. He aspires to be a true gentleman like his professor some day.
