Lead Role. Futaba is a socially anxious introvert who tends to like holing up at home. She isn't very adept at being social, and as such, she has a hard time going outside, only becoming energetic and playful when talking to friends. Despite this, she's very intelligent and also a skilled hacker. In the Metaverse, she takes on the role of Oracle, the Phantom Thieves' Navigator.

A good note of reference is the official English lines of Futaba from any of the official P5 material (aka Erika Lindbeck). Futaba's voice is somewhat sharp and peppy in tone, and she's very high in energy majority of the time.
