Darknest appears as a tall humanoid wearing a long cape, whose snake-like features are based on the Japanese yokai Uwabami. Darknest's face is hidden in the shadows with her voice distorted to hide the fact that she is actually a Star Princess.
As the Ophiuchus Star Princess, she has long wavy emerald green hair that reaches her feet, held up in several purple bands with two long crimson strands in the front. Her eyes are bright yellow with green pupils that also have glowing red stars in them.
She wears a sleeveless dress with dark indigo and light purple bodice that is lined with gold at the top along with a feathery purple collar. The skirt is floor-length and purple with a dark indigo layer over it. Along the middle is a white section decorated with light purple oval-like designs and an indigo border.
Her accessories include a gold halo-like tiara that resembles a snake, a gold choker, gold crescent-shaped earrings, a wrap around her arms that resembles a bright green snake, and two gold bands on her upper arms. She later takes Garuouga's bracelet.
She also loathes imagination because she regards it as a failed product of the universe.
Darknest has the ability to power up the Notraiders and can also produce holographic projections.
- Garuouga - The second in command in the organization.
- Kappard, Tenjo, and Aiwarn - Darknest's subordinates.
- Star Princesses - Darknest sees and despises them as failures of the universe and only yearns for their magic.
Prior to the season, Ophiuchus created the universe and lived with the other Princesses but grew to despise the universe as her mind grew distorted. She then abandoned the princesses, destroyed the home planet of Garuouga and became Darknest, recruiting the Notraiders.
- Their voice is disorted for most of the season's run, obscuring Darknest's background and identity as a Princess.
