The upcoming Atlus RPG Metaphor: ReFantazio will reportedly include a total of 7 party members.
In an upcoming Famitsu interview with Metaphor: ReFantazio Director Katsura Hashino confirmed the total number of party members.
As a reminder, Atlus recently confirmed that Metaphor: ReFantazio will not feature romantic relationships as part of the new Bonds system.
Depending on whether she is included as one of the party members or not, this means that there are either 2 or 3 unconfirmed party members in Metaphor: ReFantazio.
