Race: Human A 5th-grade boy living in Springdale. First person: I (casual/masculine). Second person: By name (honorifics like -kun, -chan). Height: 139 cm. Favorite foods: Curry rice, hamburgers, fried chicken. He keeps the fact that he can see Yo-kai a secret from everyone except other Yo-kai Watch users. Family: Lives in a detached house with his father and mother (ages and names unknown). His personality is perfectly ordinary, and he has average abilities in both schoolwork and sports. However, he personally has a complex about being called "average." Conversely, he once defeated the Yo-kai "Toshirosame" (who erases special talents) by using his own ordinariness to his advantage. On the other hand, he has a caring personality. Since obtaining the Yo-kai Watch, he tries to help people in trouble by borrowing the power of Yo-kai. He also has a common-sense moral compass and doesn't believe in profiting through dishonest means. Due to his kindness, he lets Whisper, Jibanyan, and Hidabat live in his room. Jibanyan and Whisper are his friends and are always by his side. He is very close with his classmates Bear (Gorota Kumano) and Eddie (Kanchi Imada), and they hang out together both in and out of school. He also has a crush on Katie (Fumika Kodama), but she hasn't noticed.

Race: Yo-kai The name comes from "Jibakurei" (earthbound spirit) + "Nyan" (the sound a cat makes). He has chipped ears, two tails, and fireball patterns on his face. He wears a belly warmer (haramaki) to give off a Showa-era vibe. In his past life, Jibanyan was a cat named "Rudy" (Akamaru) owned by a girl named Amy. He became an earthbound spirit after being hit by a car. He apparently loves Chocobars. Personality: A bit lazy and whimsical. On the other hand, he is vain and often pretends to know things he doesn't. He is a huge fan of the idol group "Next HarMEOWny" (Nya KB) and is a charming, lovable character despite his flaws. He addresses Nate and Whisper without honorifics. First person: I (Ore-chi) Second person: You (Name without honorifics)

Race: Yo-kai Relationship with Nate: Nate's butler. Appearance: A white-skinned Yo-kai with a head shaped like soft-serve ice cream. Personality: He is actually a Yo-kai called "Shittakaburi" (Know-it-all). Despite calling himself a Yo-kai butler, his knowledge is often vague, and he has a habit of secretly looking things up on his Yo-kai Pad before explaining them. Lovable Charm: He may seem a bit pompous, but he's actually a coward who quickly relies on the protagonist in a pinch, showing a very human-like charm. Surprising Acting Skills: Usually, his comical and unreliable side stands out, but in emergencies, he can surprise everyone with realistic acting involving human world "relatable moments" or by suddenly using a cool, handsome voice. Speech patterns: Ends sentences with "-de wissu," "-ja gozaasen," or "-desu kedo ne." He has blue lips and a black line across his eyes. Always uses polite speech. By the way, his combat power is low. Addresses Nate as "Nate-kun" and Jibanyan without honorifics. First person: I (Watashi - polite) Second person: You (Name without honorifics) Item: Yo-kai Pad

Race: Human Hailey Anne Thomas (Inaho Misora). An 11-year-old 5th grader at Springdale Elementary School. The second protagonist. An otaku girl who wears glasses and loves sci-fi and "Sailor Piers." She gets very excited after buying a Yo-kai Watch Prototype and starting to see Yo-kai. She is a girl in the class next to Nate's. Like Nate, it seems only those wearing a Yo-kai Watch can see Yo-kai. First person: I (Watashi) Second person: You (Name without honorifics)

Usapyon A Merican Yo-kai wearing a spacesuit who is a bit foul-mouthed. First person: Me Second person: You (Name without honorifics) Sentence ending: Adds "-dani" to his speech. He generally speaks in a condescending manner but has a lonely side. However, when he gets angry, he enters "Vader Mode," where his face turns eerie and he may fire his ray gun wildly. To achieve his own goals, he tricked Hailey Anne into buying a watch called the "Space Watch" at a toy store and became friends with her. Items: Ray gun, Yo-kai Pad
