Dr. Arinsu

Dr. Arinsu is fairly tall with long white hair that she styles to be upwards, with a single bang similar to the Angels and has a similar pale pink complexion like her siblings. She wears light makeup that consists of a dark purple lipstick, maroon eyeliners with styled eyelashes, and black nails. Arinsu wears a dark pink shirred bandeau dress that has a split skirt from the front with a red lining. She ties a red sash around her upper dress and wears a light grey skirt underneath her upper dress with a pair of magenta opera fingerless gloves and a dark red cape which extends as a collar, with a black underside and is attached to a purple jewel with a golden bezel. She also wears a golden choker, as well as a pair of white high heel boots with grey soles.

Dr. Arinsu has a sassy yet charming personality when she talks to people in order to further her plans of research. As a Glind, she is extremely enthusiastic about life and her curiosity to learn more about it behind everyone's back as shown when Gomah and Degesu find out that she had been sneaking out of the Demon Realm.

She is also shown to have a sarcastic sense of humor as shown when she addressed Gomah as "King Gomah" and is very manipulative by taking advantage of his status to make him paranoid enough to turn the Z-Fighters back into children so they "couldn't pose a threat to him" which in turn sets in motion the events of Daima.

Dr. Arisnu is very power-hungry, wishing to take the title of Supreme Demon King for herself by usurping Gomah. Coupled with her ambitions is her craftiness and wit. She cleverly manipulated Gomah into turning the Z-Fighters into children in order to lure them into the Demon Realm. Using Glorio as a spy, she had him escort Goku to the Tamagami in order to defeat them and obtain the Dragon Balls, saving herself the trouble of being forced to gather them herself.

Dr. Arinsu is an ambitious witch who plans to usurp the position of Supreme Demon King. To this end, she plots to use varying means of gaining power, including seizing the Demon Realm Dragon Balls and creating a powerful Majin to act as her enforcer.

To achieve the latter, she conspires with Marba, the creator of Majin Buu, but all attempts are failures, with the most recent being unable to defeat Arinsu herself. To strengthen the final product, Dr. Arinsu left the Demon Realm and heads to the planet Earth after discovering Majin Buu's presence. On May 7, Age 774, she witnessed Buu regenerating himself after withstanding Majin Vegeta's Final Explosion and retrieved one of his fragments for herself.

At some point, Dr. Arinsu hired Glorio to work for her, using him as a proxy to try and manipulate Goku into retrieving the Demon Realm Dragon Balls for her.

Dr. Arinsu appears at the Demon King Palace to confirm her research is going splendidly and congratulate Gomah on becoming the new Supreme Demon King. Degesu realizes Arinsu was watching from somewhere being that she was curious since Dabura wouldn't usually go to the outside world. Gomah agrees and tells Arinsu that since Dabura's dead, her funding is gone too. However, Arinsu states that Gomah will continue to fund her research otherwise the warriors who defeated Majin Buu may invade Demon Realm. She then leaves as a paranoid Gomah and Degesu scheme to use Earth's Dragon Balls to turn the Dragon Team into children which Arinsu agrees with behind them, scaring the both of them and leaves again.

Dr. Arinsu secretly keeps contact with Glorio over the course of his journey with Goku and is pleasantly surprised when Glorio informs her that Goku secured one of the Demon Realm Dragon Balls after defeating Tamagami Number Three.

Later, she goes to conspire with Marba who took Buu's fragment to concoct a potion meant to create a powerful Majin. Marba mentions the fragment improved the potion's flavor, so she and Arinsu decide to give it a test run. Looking at Marba's Majin mark, Arinsu reveals she knows Marba was the one who originally created Majin Buu per Bibidi's request but promises not to tell anyone. Marba explains that because Buu was so powerful it was extremely difficult to control him leading him to go on a rampage and cause many races to flee the Demon Realm whilst also leaving a trail of casualties. To avoid such an event, Marba instructs Arinsu to spit some of her saliva into the pot to create a link between her and the soon to be Majin so that she can have a better control over its actions, to which she complied.
