Although it has been over 30 years since Majin Buu first appeared in Dragon Ball, it wasn’t until nearly a year after the global release of the Dragon Ball Daima anime that the series finally addressed the biggest theory about the true nature of the Majin race.
For years, fans have wondered why Majin Buu’s behavior shifts instantly from a ruthless destroyer to a childlike sweet tooth. The directors of Dragon Ball Daima, Aya Komaki and Yoshitaka Yashima, have now answered these questions by revealing the real nature of the Majin in the latest anime guidebook.
Majin Introduced Over 30 Years Ago

The term “Majin” was first introduced in the Dragon Ball manga in March 1994, alongside the debut of Majin Buu. At that time, fans believed Majin referred to a special race with traits similar to Buu.
However, later in Dragon Ball Daima, Majin was revealed to be a term describing various magical and demonic beings. This left fans still uncertain about the true nature of the Majin, all stemming from the mystery around Majin Buu.
Although considered a demon, Majin Buu’s behavior changes rapidly, sometimes fiercely determined to fight, other times craving sweets like a child. This led both characters in the story and fans to believe he acted like a kid.
Now, after 30 years of waiting, the Dragon Ball team has finally addressed the biggest theory about the Majin in the new anime guidebook. When directors Aya Komaki and Yoshitaka Yashima were interviewed, they were asked directly about the true nature of the Majin.
Dragon Ball Daima Directors Uncover Majin’s True Nature

In an interview for the Dragon Ball Daima guidebook, directors Aya Komaki and Yoshitaka Yashima shared that they received many instructions from the late creator Akira Toriyama and executive producer Akio Iyoku, including guidance on the true nature of the Majin.
Director Yashima recalled Toriyama’s explanation: “Majin are Majin, they are not the same species as humans.” Komaki added that Majin emotions don’t build up gradually like humans. Instead, they shift fluidly depending on the situation, focusing entirely on whatever they feel at the moment.
To illustrate, the directors used Dr. Arinsu as an example. After fighting alongside the Mini-Goku group against King Gomah, she no longer held resentment and seemed completely changed. This explains why Majin Buu’s behavior also changes quickly depending on the situation.
For years, fans thought this was linked to Buu’s childlike attitude, but as Komaki and Yashima discovered, it’s all part of the Majin’s true nature.
