A member of Planeptune's Intelligence Division. She's known Neptune and Compa for a long time, and they're all close friends. As one of the few people around with any common sense, she's often pointing out and chastising the others' shenanigans. IF is usually preoccupied worrying over Neptune and Compa's lack of common sense. She's generally very cool and mature, but if she loses her smart phone, she can become restless and overwhelmingly anxious.
