Stranger of Paradise: Final Fantasy Origin Creative Producer Tetsuya Nomura has shared several development details regarding the title in an interview. This includes reasons behind certain design decisions.

Nomura elaborated in the interview for the reason placing the protagonists in modern clothing. This is because the characters, as mentioned in previous interviews, are not from this world. This was something he wanted to see easily conveyed. Their attire is also nondescript because he wanted every character to lack an identity. Plus, players will constantly be swapping out armor as they progress through the game.
Further in the interview, Nomura said about the conceptualization of the plot Stranger of Paradise:
I made an initial draft for the plot but asked Tomoco Kanemaki to put everything together as a scenario.
