Description
Dra. Arinsu is a character from the anime Dragon Ball Daima. She is a female member of the Glind race, the same divine species as the Supreme Kais, which gives her an exceptionally long lifespan and access to godly ki. As a Glind, she has smooth pale pink skin, large indigo eyes, and long white hair styled into a tall, dramatic pompadour. Her attire typically consists of a purple dress and a red cape. She holds the title of Demon Supreme Kai and is the elder sister of Shin, the Supreme Kai of Universe 7, as well as of Degesu, another prominent figure in the Demon Realm.

In terms of personality, Arinsu is highly ambitious, intelligent, and manipulative. She is a brilliant scientist who values her research above all else and is not afraid to play political games to secure funding for her projects. Unlike her brother Shin, who left the Demon Realm, Arinsu chose to remain, driven by a desire for power and influence. She is patient and calculating, often working from the shadows to achieve her goals rather than confronting enemies directly. Despite her villainous plans, she is pragmatic and willing to set aside her ambitions when faced with a greater threat, demonstrating a certain flexibility and even a begrudging sense of cooperation.

Her primary motivation throughout the story is to usurp the throne of the Demon Realm and become its ruler. Unlike the current king, Gomah, she desires a more fearsome and powerful realm. To achieve this, she concocts several schemes. She initially manipulates the newly crowned King Gomah into transforming the Z-Fighters into children, using his fear that these powerful warriors might invade the Demon Realm. Her true plan, however, is far more elaborate. She hires a demon named Glorio to travel with the now-diminished Goku and his friends, secretly instructing him to gather the three Demon Realm Dragon Balls for her. Her ultimate wish is to gain enough power to rule the Demon Realm without fear of being overthrown, a fate that befell previous rulers like Dabura.

Arinsu plays a central role as the mastermind behind the main conflicts of the series. Her most significant contribution is her collaboration with the witch Marba, the original creator of Majin Buu. During the events of the Buu saga on Earth, Arinsu secretly collected a fragment of the villain. Using this sample, her own saliva to create a genetic link, and a Saibamen seed, she and Marba create two new Majins. The first, Majin Kuu, is deemed a failure after he forfeits a fight against a Tamagami guardian. The second, Majin Duu, is more powerful and successfully defeats a Tamagami, securing a Dragon Ball for Arinsu.

Her key relationships are largely transactional. She employs Glorio as her agent, but he ultimately betrays her by making a different wish with the Dragon Balls. She works as a superior to the childlike Majins Kuu and Duu, showing a surprising amount of patience as their creator, even when they fail. She despises the new Demon King Gomah and views her brother Degesu as a rival. Her relationship with Shin is distant, defined by their opposite choices to stay in or leave the Demon Realm.

Over the course of the story, Arinsu undergoes a notable development from a hidden antagonist to a reluctant ally. When King Gomah acquires the Evil Third Eye and becomes a rampaging, unstoppable force, Arinsu recognizes the danger he poses to her own ambitions and to the entire realm. She agrees to a temporary truce with the Z-Fighters. Using her knowledge, she discovers the only weakness of the Evil Third Eye: striking the wearer on the back of the head three times. Her Majin Kuu is instrumental in executing this plan, leading to Gomah's defeat. After the crisis, she refuses Shin's offer to become the new Demon Supreme King, citing the lack of a mechanism to prevent being overthrown. In a surprising turn of events, the newly crowned Majin Kuu appoints her as his Vice-Supreme King, a position she accepts, finally finding a role that satisfies her ambition for power and influence within the new political structure.

As a scientist of the Glind race, Arinsu's most notable abilities are not raw combat power but her intellect and scientific knowledge. Her primary achievements are the creation of Majin Kuu and Majin Duu. She is also skilled in magical research, as she was able to locate a counter-spell to the Evil Third Eye in an ancient spellbook. While not a primary fighter, she possesses the inherent abilities of her race, including generating and manipulating godly ki and surviving for tens of thousands of years without food.
