When you start Persona 5: The Phantom X, you’ll be tasked with naming the protagonist by writing down your name on a worksheet fairly early. If you’ve played Persona games before, you may be familiar with the protagonists’ “official” names from the series, and want to use the canon name for this game, too.
Lucky for you, the canon name should have been filled in already, but if you accidentally deleted it or you don’t know if this is the real deal, then we explain more about the P5X protagonist’s canon name below.
What’s the protagonist’s canon name in Persona 5: The Phantom X?
In Japanese, the canon name for the Persona 5: The Phantom X protagonist is Nagisa Kamishiro. However, this doesn’t fit in the name slot for the English version of the game — so the canon name for the global version is Nagisa Kamisiro.
Ultimately, you do not have to name your character Nagisa, of course. You can literally name him whatever you want. You can name him Zoo Smell, if you want. (Just make sure to change both his first name and last name, if you wanted to. We saw a lot of names in the beta where only the first name was changed, for some reason.)
It should be noted that since this is a game with online friend capability, the name you set is your account name. You may want to pick something unique or you’ll be one Nagisa Kamisiro in an ocean of them. If you plan on adding a bunch of friends in-game, you may want to set your name as something your buddies can identify.
That is all to say that “canon” has different definitions across the board. Persona protagonists have had varying names across media. For example, the Persona 4 protagonist is named Souji Seta in the manga, but Yu Narukami in Persona 4 Arena and the anime adaption. Similarly, the protagonist from Persona 5 was named Akira Kurusu in the manga adaption, but has canonically been referred to as Ren Amamiya, which was the default name in Persona 5 Royal. (Ren is fine, but to me he’ll always be Akira!)
It’s entirely possible that Nagisa will appear elsewhere in other media with a different name, but we’re basing this off of the default name available to us in the beta that we played.
Can you change the protagonist’s name in Persona 5: The Phantom X?
Yes! If you went with Nagisa (or Zoo Smell, by our recommendation) and you’re regretting it, you can change your name for free once. After the first name change, you’ll need to pay 200 Meta Jewels (the premium currency that you can earn by playing the game) for every subsequent change.

You can change your name by clicking your profile icon at the top of your phone screen menu, but only after you’ve progressed a bit in the story. From there, click the ellipses above your set icon to access the name change feature.
