Dr. Arinsu

Dr. Arinsu is a Glind scientist from the Demon Realm and the older sister of Shin and Degesu. She wanted to replace Gomah as Supreme Demon King, so she kept her research funded by feeding his fear of the warriors who defeated Majin Buu. Before Gomah’s plan fully unfolded, Arinsu had already gone to Earth, witnessed Buu surviving Majin Vegeta’s Final Explosion, and collected a fragment of him for her own experiments.

Arinsu worked with Great Witch Marba, the maker of Majin Buu, to create new Majins that she could control through a biological link. This led to Majin Kuu, then Majin Duu, while Glorio secretly acted as her agent around Goku’s group to help gather the Demon Realm Dragon Balls.

Appearance: Dr. Arinsu has vivid pink skin and a short, slim curvy build with a narrow waist, full chest, slender arms, and a small frame. She has pointed ears, pale gray eyes, and extremely tall white hair swept upward in a high curved shape, with a long white side lock falling beside her face. Her fingers have long pale nails.

She wears a fitted dark purple bodice with red edging, a low neckline, long pink sleeves, and a red waist sash tied in front. Her skirt is layered in deep purple and red, with a pale blue-white underskirt visible through the front opening. A black cape hangs behind her with red trim and a high flared collar framing her neck and shoulders.

A gold choker with a large round red gem sits at her throat, matching the gold and red clasp at the center of her cape. She wears tall white boots with simple folded tops and small heels.

Personality: Dr. Arinsu is calculating, ambitious, and more patient than Gomah or Degesu. She presents herself as a researcher, but her work is tied to political power, since she uses Gomah’s fear of Goku’s group to keep her funding and secretly plans to take the Demon Realm’s throne for herself. She prefers manipulation over direct battle, sending others into danger while she stays near the information, tools, and creations that can give her control. Her confidence is real, but her plans depend heavily on people and Majins who do not always obey the way she expects.

Her brothers are Shin and Degesu, placing her in the same Glind family but on a very different path from Shin. Gomah is both her sponsor and her intended obstacle, since she works under his rule while plotting to replace him. Glorio is her agent, rescued by her in the past and sent to guide Goku’s group toward the Demon Realm Dragon Balls, though he eventually hesitates to keep serving her plan. Marba is her research partner in creating new Majins from Buu’s essence, producing Majin Kuu and later Majin Duu as weapons meant to secure her rise.

Dr. Arinsu is not shown as a major direct fighter. Her strength is scientific ability and Demon Realm expertise, especially in creating controllable Majins from Majin Buu’s remains with Great Witch Marba’s help. This leads to Majin Kuu, then Majin Duu, who are meant to act as weapons for her rise in the Demon Realm.

She is also skilled at planning around stronger beings rather than overpowering them herself. Arinsu uses Glorio as an agent, studies the Demon Realm Dragon Balls, and later helps search for a way to remove Gomah’s Evil Third Eye after he becomes too dangerous.
