Dr Slump Wiki

Midori Yamabuki (山吹みどり Yamabuki Midori) (later Norimaki) is one of the main supporting characters of the Dr. Slump series. She was originally Arale Norimaki's beautiful teacher at Penguin Village Middle School as well as Senbei Norimaki's dream girl. Later on in the series, she becomes Senbei's wife and Arale's surrogate mother.


Midori has big curly blonde hair. One notable trait about her appearance is that she looks similar to Akane, a fact which Akane used to play a prank on Senbei by dressing up as Midori. During the Penguin Village Grand Prix race, Midori and Akane teamed up and attempted to cheat by taking advantage of their resemblance.


Midori is a very friendly and kindhearted teacher who loves all her children. While normally sweet to everyone, she can get really angry on occasion. She also can be quite ditzy and scatterbrained, and this side of her personality is especially prominent in the second half of the series, after getting married.

Senbei attempts to save Midori by morphing the ape creature into an ant using the Ponpoko Morph Gun and smashing the ant.

The Crazy Honeymoon[]

Main article: Volume 9: The Crazy Honeymoon


Senbei and Midori married.

When bringing some giant-sized carrots over to Senbei's house, Midori has to use the bathroom and as Senbei is walking past it, he talks to himself and says "will you marry me," to which Midori, who's within earshot, hears and immediately agrees, and their wedding finally happens.

While preparing for their honeymoon, which was going to be in space, Midori was kidnapped by some black cat-like creatures in a flying canoe and taken to an island where she was tied up as an offering to a giant ape. Once the giant ape gets her, she is taken to the top of a mountain where she gets stripped down naked and thrown into a pot to be cooked and eaten. Senbei, Arale, and Gatchan find Midori after following the signal on the Lost-N-Found badge she was wearing, and destroy the mountain and defeat the ape. However, Midori is still in the pot and is taken away by the ape's friend, who is a caveboy with a giant fork. She was taken to Torishima (an island that is also a giant flying bird) where she is now in a squash. She is rescued when Senbei flies to the island holding Gatchan and pulls her out of the pot while she is still wearing the squash. Midori ends up falling when Senbei lets go after she kisses him for saving her. After landing on the ground, Midori witnesses the battle between Arale and the caveboy, who has equal strength and abilities as her, and then the battle between Senbei and a giant crab. After the battle was over, Midori and the others get into Senbei's ship and fly off, but the caveboy wakes and blasts it down with a N'cha Cannon thereby forcing Gatchan to have to tow them back to Penguin Village.
