Baku has the appearance of a purple and pink tapir. She has yellow eyes with red irises and black pupils. She has small, pointy, horns that are a different color purple than her body, but the same color purple as the tuft of fur on her tail. Baku has an orange flower-like design next to his eyes. She also has sharp teeth on both her upper and lower jaws.

Baku can put her targets to sleep, allowing her to eat their dreams. The dream takes the form of translucent clouds that can also be viewed like a movie if she doesn't immediately eat them.

In the first game, Baku can also demonstrate the appearance of a human. This allows the player to go out at night without their parents knowing, as Baku takes the player's place in bed, asleep. Baku's dream eating also removes all traces of tiredness from the player, allowing them to be indefinitely energetic and not feeling exhausted.

  • Traded (Yo-kai Watch 2): "Baku's tired of eating [player's name]'s dreams. Be Baku's new friend!"

In the anime

In Yo-kai Baku, Baku puts everyone, but Nate in school, to sleep in order to eat their dreams. Despite Nate catching her in the act, but she refuses to stop, saying that she'll only stop after feasting on an incredible dream as she considers all the dreams she's eaten so far, as unfulfilling. Eventually, Nate summons Shogunyan, whose dream of being 80 feet tall, which it leaves Baku awestruck. After eating Shogunyan's dream, she happily gives Nate his Medal.

Later Baku's summoned in Yo-kai Insomni to deal with Insomni, after the Insomni Inspirited everyone into not getting any sleep at night. After their attacks collide, Baku and Insomni appear to have a faceoff in a wrestling arena where the two faceoff their powers; eventually Insomni triumphs. However, the sequence turns out to be Insomni's dream, and she's revealed to have fallen asleep, the instant she was hit with Baku's hypnotic smoke.

In The New Yo-kai Watch, Baku was seen in Yo-kai-Lifornia where she's among the Yo-kai waiting in line for the release of the Yo-kai Watch Model Zero.

In the manga

Baku appears in ND015 so that Katie and Nate cannot do the homework, Katie and Baku become friends.



Baku's based on the dream eating yokai of the same name. Originally from China, this beast is described as having "a bear's body, small eyes like a rhino, a long snout, a bovine tail, strong legs like a tiger's, and a spotted pelt": overall it resembles a tapir, and in fact, the word "baku" is also used to refer to the animal.

This creature will feed on good and bad dreams alike while people are asleep. Those who're woken up by nightmares will invoke its name to let it devour them so they can peacefully go back to sleep, and it's said that even the general Hideyoshi Toyotomi kept a picture of a baku by his bedside to keep nightmares away. It's also said that anyone who sleeps on a baku's pelt will never get sick.


  • In Yo-kai Watch 2, Baku's random nicknames are Dreater, Barnie, Chomp, and Crunchy.
  • Baku tends to refer to herself in third person.
  • In the games, Baku is often referred to as male.
