I would not call the name canonical, it's just what they used in the Manga adaptation, and history has shown us that Atlus plays fast and loose with protag names in spinoff media. The P3 protag has 3 names. P4's protag got two. It's the only actual name we have for now, I guess? I would just pick something else. :V
Excuse me, but we do have canon names for the MCs.
Persona 3: MC
Persona 4: Protagonist
Persona 5: Harry Potter
probably just thought "I am the real me, therefore the other me is fake."
Coulda been like a similar looking girl...
