Rachnera Arachnera is an Arachne, the sixth girl to move in with Kimihito and the fifth to officially do so. Known for her striking appearance, sharp wit, and complex personality, Rachnera is both alluring and intimidating.

Due to the fear she inspired in humans, her original family sold her to Kasegi, who exploited her and her webbing for profit. This cruel treatment fostered a deep-seated mistrust of humans. However, her perception changes after she abducts Kurusu and discovers his kindness and acceptance of Liminals.

She becomes the housemate of the protagonist, Kimihito, and develops romantic feelings for him, leading to conflicts with other female characters who also have feelings for him.

Rachnera Arachnera is a striking and unique character. Her upper body is that of a beautiful young woman with long, flowing purple hair that often covers one side of her face. She has an unusual feature: six pupil-less red eyes that give her a somewhat intimidating appearance.

However, her most distinctive feature is her lower body, which is that of a large spider. Covered in black, it starkly contrasts her human-like upper half. Her spider legs are powerful, allowing her to move with surprising speed and agility. Despite her monstrous lower half, Rachnera carries herself with confidence and grace.
