A pale pink yo-kai with a tiny brown button nose, and four oval-shaped eyes with dark raspberry pupils. Each eye is lined by dark brown with three spiked lashes on top. At the end of each ear is a dull purple marking. She wears a lavender kimono accented with ivy and plum accents, with a white pearl necklace.
Despite her abilities, Infour is surprisingly humble about them, unlike her lookalike Espy. In the anime, she takes pity on a down-on-her-luck Fortune Teller.
Each of Infour's eyes can identify a specific characteristic about a person Infour is looking at. In the anime, this is stated to be a person's name, birthday, favorite food, and future soulmate. However, using her abilities too often can put a strain on her eyes, and the eye for identifying a person's soulmate has been shown to be prone to being incorrect.
Visions that Infour sees can be projected, such as onto a camera, which can subsequently be adjusted when Infour focuses.
One way to find Infour is in the 2nd Quiz Room behind the 40 Gate Globe Gate of Whimsy. She always appears in the top right tree.
Additionally, Infour can be found on trees,street poles and trash cans in San Fantastico.
In EP062, Infour is identified as a Yo-Kai that had Inspirited a fortune teller named Madame Four-Eyes, giving the fortune teller her powers, which she used to perform a fortune-telling show with Katie Forester, revealing her "Fated Partner" to her. Intrigued, Nate confronts Infour, who explains that she Inspirited Madame Four-Eyes out of pity as the fortune teller lacked any psychic ability. She agrees to help Nate find his "Fated Partner", but due to the eye she uses for that power being on the fritz, her multiple attempts end up failing, much to Nate's distress.
