The Nosir triplets are a group of three Yo-kai who resemble each other in terms of appearance. They all have short statures, purple sweater vests, blue bowties, magenta pants, and black eye masks. Their large, thick noses and dirty blond hair set them apart from one another. To distinguish between the Nosirs, one wears glasses while another has a nose hair sticking out of his nose and carries a vanity mirror. In the English version of the anime, the Nosir with the nose hair is depicted as having olive-colored mucus instead. The Nosirs are known for being ungrateful and denying everything, even when complimented on their appearance. They often say phrases like "Uh-uh-uh" or "Nosiree Bob!" when correcting people. When inspiring others, the Nosirs cause doubt in their decision-making processes. In academic settings, they can create unnecessary stress levels. The leader of the Nosir triplets is capable of merging into objects such as the Yo-kai Watch and serves as its source of sound when a Yo-kai Medal is inserted incorrectly.
