Buyo

was Kagome Higurashi's overweight cat in modern-day Tokyo, and led to her falling through the family well into the sengoku jidai.

History
Buyo was the reason Kagome first found the well, since she was looking for the cat for her brother. Buyo belongs to the Higurashi family and has been part of their family for an unknown length of time, but it's likely he has been a part of their family for a while. Kagome and Sōta would often give him stupid artifacts that they had been given by their grandfather and he would eat them.

Hanyō no Yashahime
Buyo was the first one to encounter a young Towa in front of the Sacred Tree when she catapulted to the modern era.

Personality
Buyo is very lazy, like many house cats. Most of the time, he would be found on Kagome's bed sleeping or wandering around. Buyo mostly provided comic relief to the series.

Physical description
Buyo is an overweight of average height and with multi-colored fur. There are various patches of brown and black on his white fur. He has a patch of brown over his left ear stretching all the way to midback, on the bottom half of his front left leg, and one on his bottom by his tail. There are black patches in the middle of the two brown patches located on his back. He has claws, but does not always bring them out.

Relationships
Inuyasha liked to play with him on the occasions when he visited Kagome's house in the modern era though Buyo apparently does not seem to enjoy it when Inuyasha gets too rough with him. Most of the time though, Buyo doesn't mind. Sōta is seen doing this as well.

Trivia

 * In the series, Buyo's name is written in katakana, as "ブヨ", which can be translated as 蚋 (lit. "Gnat"), OR as 舞踊 (lit. "[formal] dance").
 * Buyo's name can also be a nod to the Japanese term, "ブヨブヨ", "buyo-buyo" (lit. "[really] flabby" & "[really] squishy"); apt for Buyo the cat's chubby, overweight body.
 * Despite how Inuyasha has occasionally shown dog instincts (as he is part dog yōkai); such as how Kagome played fetch with him or how he tried to dry himself in the same manner as an actual dog as well as sitting like a dog, Inuyasha does not seem to react much to cats as seen when he, from only his view, harmlessly plays with Buyo.
 * Buyo's seiyū, Ginzo Matsuo, was also the first voice of Kagome's grandfather, while his English voice actor, Richard Cox, was also the voice of Inuyasha.
 * A stuffed toy version of Buyo appears in Meeting Through an Apple during Towa's dream.
