Dragon Ball Wiki

Senbei Norimaki (則巻千兵衛 Norimaki Senbē, also spelled as 則巻センベエ) is Penguin Village's goofy and lecherous genius inventor. He is capable of creating wacky inventions that defy logic with his greatest accomplishment being the creation of a powerful robot in the guise of a little girl who he claims to be his younger sister named Arale Norimaki. He isn't very well known outside of the village but is actually one of Earth's greatest scientific minds as he was secretly the first to successfully create a perfect Android and has won the "World Invention Award" for his creation the Reality Machine 2.

He is the title character to Akira Toriyama's previous series, Dr. Slump as well as a minor supporting character in the Dragon Ball manga, anime and Dragon Ball Super.


Senbei's serious look

He can also transform into a more handsome, taller version of himself (for a very brief period of three minutes). Senbei Norimaki's name is from Senbei Norimaki (a kind of Japanese rice cracker), whereas Arale Norimaki's name is from Arale, a different kind of rice cracker. Norimaki means "wrapped", and it refers to a specific type of each respective kind of rice cracker.

Though Akira Toriyama often draws most of the characters short and chubby, especially Senbei Norimaki, there are times Senbei Norimaki becomes more "realistic", becoming quite tall and rugged-looking. Usually this is when he puts on the best face he can for a pretty girl such as Yamabuki.



Sometime when Senbei was young, his parents passed away. Also when he was young, Senbei began hating dogs when one told him that he was stupid.

Dr. Slump

Senbei creates Arale

Senbei's life changed when he created an android who he passes off as his younger sister named Arale. In many episodes, he invents something and Arale Norimaki calls him Doraemon.

Senbei developed a huge crush on the Junior High School teacher Midori Yamabuki, who he dreams about a lot. In one episode, he actually gets a date with Midori and goes into space. On the way back, Arale Norimaki's friends play a prank on them for leaving them behind. They dress up like old people, and say that the time is 2030 (the year in the Manga being 1981). Senbei finally marries Midori Yamabuki after he proposed to her while she was on the toilet. A year later, they have a son named Turbo Norimaki.

Senbei with his wife, in Dragon Ball

When Goku was chasing General Blue in the skies of Penguin Village, Senbei constantly made peace signs in front of the screen since it has been awhile since he had been been in Shonen Jump (or on TV, in the anime). Akane Kimidori yells at him for being stupid. Goku and Arale later show up at his house and ask if he could fix the Dragon Radar so he can find General Blue.

Senbei was confused by its really advanced technology and was even more put down when Goku said a girl made it. Turbo secretly saved him from looking like an idiot by fixing it behind Senbei's back using his telekinetic abilities. General Blue shows up at his house and attempts to kill Goku and steal Senbei's plane, but Arale defeated him. While General Blue got away with the Radar, Senbei let Turbo take his airplane apart to make Goku a new radar.

Senbei showcases the Reality Machine 2

Senbei is invited to attend a ceremony for the "World Invention Award" in West City and enters his latest invention the Reality Machine 2. Before leaving, he tells Arale and the Gatchans that they can't come and tells them to watch the house. At the ceremony he ends up winning the award even against Bulma who was expected to win. Dr. Mashirito who escapes Hell as a ghost confronts Senbei at the ceremony and tries to get revenge for not being invited.

When Arale and the Gatchans crash the party and under control by Mashirito, Senbei helps Bulma summon Beerus by having everyone use the Reality Machine 2 to create a pill containing all of the world's delicious food. After Beerus stops the fight between Arale and Goku and erase Mashirito from existence, Senbei says farewell and drives away with Arale and the Gatchans.[1]

Appearances in other media

Dr. Slump remake

Senbei in the remake

In the 1997 remake, Senbei's face and hair was changed a bit. His intentions for creating Arale were changed as well. He originally intended to make an attractive maid for him but it went wrong with Arale ending up being an accident. When Goku shows up in the remake Senbei is forced to spend days trying to fix the radar (Turbo was not born yet in the remake to fix it for him).

Video Game Appearances

Senbei with Turbo and Midori in Origins 2

Although he does not appear directly in Dragon Ball Z: Budokai Tenkaichi 3, his voice is frequently heard in the Penguin Village level.

Voice Actors


A farmer that resembles Senbei in Battle of Gods

  • Senbei can hold his "serious face" for only 3 minutes.
  • It seems people can see Senbei's "serious face" since Goku asks how he did it.
  • Senbei can be seen wearing a Pennzoil shirt in Dragon Ball.
  • A recurring joke in the Dr. Slump series revolves around Senbei's inability to keep his story straight pertaining to his relation to Arale. Initially, he stated that she was his younger sister, however, once it was pointed out Senbei's parents died before Arale would have been born, he claimed she was actually his daughter instead. However, upon meeting Midori Yamabuki, he immediately claimed she was his sister again, passing off his previous comment as a joke.
    • Later on in the series, Senbei's grandfather, who had never met Arale, comes to visit. After being told that Arale is Senbei's fifteen-year-old sister, Senbei's grandfather points out that this is impossible, as Senbei's parents died twenty years prior. This leads to Senbei inventing a new backstory stating that Arale was actually a baby that he recieved as a prize from a box of caramels, and that Gatchan was a prize that came with chewing gum.
  • In Dragon Ball: Origins 2, Senbei is the one responsible the removal of Android 8's Android Bomb instead of Dr. Flappe.
  • A farmer using the same design as Senbei's Dr. Slump remake is seen in Dragon Ball Z: Battle of Gods Where he is near West City when Goku calls for Shenron, and states that the wealthy sure do put on a different show.
