Polyurethane (ポリウレタン Poriuretan) and his twin brother, Polyester, are the younger cousins of Panty and Stocking. He and his older twin brother are angels who describe themselves as "Newgen Angels". When using his own or his brother's golden thong, he can transform them into his weapon of choice, an unnamed bladed boot. Polyurethane has pale skin and gradient purple-pink hair styled with blunt bangs. His outfit is predominantly black, with his earrings, nail polish, and wristbands all being black. Much like his older brother, he wears a black choker around his neck and wears a sleeveless spandex bodysuit, although his is black. Part of his bodysuit is cut, revealing a small portion of his thigh. He wears a white cloth belt around his waist. His bulge is also visible. When angered or excited, his teeth turn sharp and pointed, akin to that of a shark's. Polyurethane, like his brother, thinks very highly of himself due to his new-age technology, which also helps him work efficiently when killing ghosts. He commonly uses Gen Z slang. Whenever things don't go his way, he becomes very dramatic and throws a fit, even to a point of getting impulsive. Polyurethane seems to have a crush on Guest, and would do absolutely anything to impress Guest. Polyester teases the hell out of his outgoing crush.

Polyester has pale skin, red eyes, and gradient purple-blue hair styled in a bowlcut with bangs covering his left eye. His accessories include a black choker and a black charm that resembles the kanji for "Heaven". He wears a sleeveless, V-neckline white spandex bodysuit along with white gloves. His bulge is also visible. Polyester has a very high ego due to the amount of new-age technology he uses. He also commonly uses Generation Z slang and AAVE, such as "on God" and "ick". Whenever things don't go his way, he becomes very dramatic. Polyester and his brother have a strict "No Work on Weekends" policy and won't so much as lift a finger to help humans being attacked by violent and malicious ghosts, though as soon as the weekends end, they both immediately resume their angelic work, showcasing a sense of professionalism.

Panty is a woman who has a slim body with light skin, modest breasts, pointed hips, and blonde spiky hair that reaches her tailbone and flows outwards, with bangs that somewhat resemble a banana bunch with a lightning-bolt highlight. Her facial features include sky-blue irises and above each eye is one elongated eyelash. Scaling from her figures, she (as well as the rest of the girls) is around 5 feet tall. She typically sports red nail polish. Style shifted, her features remain much the same, though her hair isn't as pronounced, the stem of the "banana bunch" becomes an ahoge on the back of her head, and she has regular thick upper eyelashes. Panty's most defining trait is her promiscuity; she is completely obsessed with sex and performs those sexual activities as much as she can, at one point prioritizing it over her Ghost-hunting duties. She also has quite low standards in men, a trait that Stocking mocked her several times. Panty has displayed rash and impulsive behavior, especially when battling Ghosts. She often takes the more reckless route, using pure power to finish the job. However, this style of fighting has caused her to be wide open for attacks.

Stocking is a woman who has a slim figure, with pale skin, large breasts, round hips, and dark blue hair that reaches her calves, with a second layer of pink beneath that peeks through - typically in curved, slit-like triangles, with blunt bangs. In a Q&A, it is stated she may have the trademark Royal Lightning motif elsewhere on her body. Her facial features include cyan irises, lower black inverted-triangle lashes and a curved purple shadow covering the upper quarter of her face and eyes. Scaling from her figures, she (as well as the rest of the girls) is around 5 feet tall. She typically sports dark blue nail polish. Style shifted, she has wider hips, her hair is more free-flowing, she has regular thick upper lashes, and her facial shadow remains a cool purple regardless of lighting (unless her whole face is submerged in shadow). Stocking's defining trait is her love of sweet foods. Similar to her sister Panty's obsession with sex activities, Stocking often has a compulsive need for sweet snacks, mainly cakes and pastries. Her persistent eating habits have drawn criticism from Panty. On occasions or when provoked, Stocking is shown to have quite a snarky and vulgar mouth as she tends to say foul language.
