Kyubi (キュウビ) is a Fushigi Class, Fire-attribute fox Yo-Kai ranked S. According to the Japanese Yo-kai Daijiten (yo-kai dictionary) it states 'This Fox yokai is one of the strongest out of every yokai. He can easily make a volcano erupt.' There are actually two Kyubi we know of. One is the Kyubi that tries to charm Fumi while the other is known as the Crimson Master which is the main Kyubi you see in the games.

Official Description

One of the strongest Yo-Kai, Kyubi can control fire and has the power to charm almost anyone.


Kyubi is a very feminine yokai. About twice as tall as Keita (220 cm.), Kyubi is covered in thick, golden fur. Kyubi's chest is covered in the thickest fur with a purple patch in front. That section of fur resembles a feathered boa, and four wispy hairs stick from it. Kyubi has 9 tails, each tipped purple. Long, purple nails tip each finger and toe. Kyubi's face is long and pointed, and so are the ears.

In the anime, Kyubi has taken human form several times. In human form, Kyubi is a young boy about the same age as Keita. Even in this form, Kyubi is still quite feminine. He wears a blue sweater vest over a white shirt and black shorts. He has green eyes that portray his feminine nature. He has light, greyish-tan hair in a tousled hair with two points sticking from the top lile ears. Sometimes these points become ears and Kyubi's nine tails appear when he gets excited.


In the anime, Kyubi is very proud of his appearance and is a narcissist.

In the games, Kyubi likes to bully weak Yo-kai and lead Fumi/Kenta into trouble. He's very prideful and full of himself, but still kind when pleased.


In the anime, Kyubi has tried to charm Fumi, but it appears that Kyubi was the one charmed by Fumi instead.

In the games, Venoct and Kyubi are kind of like opposites. For example, in the second game, Kyubi likes Honke while Venoct likes Ganso. In the Oni update of the second game, Kyubi got a dark form called Yamikyuubi (dark Kyuubi) while Venoct got a light form, Hikariorochi (light Orochi). 

Also in the games, the Crimson Master Kyubi is somehow related to the science teacher. Fans speculate that the science teacher is that Kyubi but in his human form. The possibility of him being Kyubi was confirmed when the quest, Miwaku no Kyun Kyun Daisakusen (The charming charm operation?) showed that Kyubi gave the Kyun balls to the science teacher because he thought he was the Crimson Master. 

Abilities and Powers

Kyubi has the ability to control fire. He also has the ability to shapeshift. Like the yo-kai dictionary says, he can erupt volcanoes easily. Kyubi can charm almost anyone, which creates a "Kyun ball" which Kyubi collects. It is suggested that these balls are a piece of the heart of someone that Kyubi has charmed. In game, he has an ability called Kansu which allows him to deal damage not caring about the typing. He can attack with his tail which has a base power of 100-150. His sorcery is Rengoku no Jyustu (Purgatory jyustu) which has a base power of 80-120. When he possesses the opponent, they get burnt which causes them to lose some HP after the opponent moves on their turn. His Soultimate is Gurenjigoku (Crimson hell) which has a power of 250. 

His normal stats at level 99 are:






Moves: Base power/status effects
Shipouchii (tail strike) 100-150
Rengoku no jyustu (Incinerate) 80-120
Inspirit: Burn Every turn the possessed yokai moves, it loses some HP

In Episode 18, Kyubi arrives in the human on a mission to collect the hearts of humans. At this point, Kyubi has already charmed 99 women and only needs one more to become a senior kyuubi. Then, he spots Fumi, and decides to make her the next target.

In Yo-Kai Watch (the game), he first appears in the chapter Kyubi, the bully
