Description
Aiwarn, once a villainous commander of the Notraiders, introduces herself as "Atai" and peppers her speech with phrases ending in "~ttsū no" or "~dattsū no," punctuated by her distinctive "Kehyahya!" laugh. Her purple-skinned appearance includes a single central eye adorned with pink eyeshadow, bright yellow hair in twin pigtails, and antennae secured by a pink headband. She dons a black top with a yellow zigzag stripe, a multicolored skirt alternating yellow and pink panels, black gloves and leggings accented with purple stripes, and pink shoes with black undersides. After deserting the Notraiders, she conceals herself in a yellow hoodie. Her adult form features shorter hair and a yellow-and-black bodysuit with a rainbow gem accessory.

Born a homeless orphan adrift in the galaxy, Aiwarn stumbled upon the Notraiders' headquarters, where leader Garuouga recruited her as a scientist to harness her rage. She engineered the Dark Pen to corrupt Princess Star Color Pens, summoning destructive Nottorigas. Her experiments petrified Planet Rainbow's entire population, and she sold the planet’s treasures to fund her work. She employed a butler, Bakenyan—later exposed as Yuni, a shapeshifting alien infiltrating the Notraiders to investigate Aiwarn.

Arrogant and reckless, Aiwarn belittles others, calling colleagues like Kappard "uncle" and Tenjo "aunt" while dismissing protagonists as inept. A sore loser who craves flattery, she nurses grudges and seeks vengeance, masking deep loneliness from her orphaned past. Discovering Yuni’s true identity enraged her, driving her to transform into a Nottoriga for revenge.

Her defection followed a failed mission, with shame preventing her return. Blaming Yuni for her resignation, she pursued vengeance by hacking Planet Saman’s AI and deploying upgraded spaceships like the Aiwarn Robo Unit 16 and Model No. 23. During the Notraiders’ assault on the Star Palace, she resisted Yuni’s empathy but intervened to save her, sparking a change of heart.

Post-redemption, Aiwarn allied with former enemies to rescue Fuwa and combat Ophiuchus, contributing her imagination to restore the universe. She accompanied Yuni to Planet Rainbow to research reversing petrification. Though fearing rejection by the Silverline Cats, Olyfio welcomed her. Fifteen years later, she integrated as a scientist, inventing soil fertility solutions and beneficial technologies.

Her abilities center on scientific innovation, notably Dark Pens for summoning Nottorigas, alongside laser guns and Aiwarn Robo combat units. Post-redemption, she shifted to constructive creations like antidotes and agricultural tools.

Aiwarn views Garuouga as a former superior and Tenjo as a rival. Her relationship with Yuni evolved from betrayal-fueled hostility to reconciliation, culminating in their collaborative life on Planet Rainbow.
