"Click-clack-click-clack..." The aberration of Reimu Hakurei, the first to appear in Gensokyo. While she resembles Reimu in appearance, countless needles sprout from her back. Her face resembles the pattern of a Yin-Yang orb, with the boundary of the pattern forming a vertical mouth lined with fangs. She pulls needles from her body to use as melee or throwing weapons and utilizes talisman-based sorcery. She does not speak, expressing her emotions by gnashing her teeth.

"Let me tell you... I could destroy Gensokyo all by myself." The aberration of Marisa Kirisame. Though she looks like Marisa, she has eerie, emotionless black eyes, and her entire body is covered in a dark tone that makes her expressions unreadable. She is the most talkative among the aberrations, though her grammar is slightly off, barely allowing one to grasp her meaning. Her combat power is among the highest of the currently confirmed aberrations, and she has displayed various supernatural abilities.

It is like a bizarre stain... The aberration of Sanae Kochiya, commonly known as "Sanae-san." She takes the form of a long-limbed humanoid monster, though at this stage, she has only appeared in hallucinations. She organizes some of the aberrations through religion, and it is said that no one surpasses her when it comes to "cursing" enemies. She curses those who kill Moriya shrine members, those involved in the killings, and those who associate with the cursed, seizing all five senses to corner them mentally before killing them with a "miracle." Those with strong minds and bodies are cursed gradually, while the weak die easily. Even scrawling insults about Sanae-san on walls or desks results in a curse. The terrifying aspect of this curse is that it continues even after death and spreads to others. As a god, she has no physical form, making it impossible to kill or erase her since physical attacks pass through her. Because her deified presence allows people to feel her power even if she is invisible, followers naturally gather. It is unknown if she has a main body, but she is said to not be entirely invincible.

"What a sorrowful Grand Guignol." The aberration of Alice Margatroid. She looks as if Alice herself has become a doll, carrying numerous thread-holders on her back. According to her, her primary mission is the recovery of the corpses of fallen comrades, and she claims to have no intention of fighting. she has made serious mentions regarding the "landmines" that the aberrations fear.

"Before my 'Fate Power,' the side of Gensokyo has not even a 1% chance of victory." The aberration of Remilia Scarlet, known as the "Demon King." She is the leader of the Aberrant Scarlet Devil Mansion, commanding subordinates like Aberrant Sakuya and a group called the "Thirteen Knights." She possesses an ability called "Fate Power," which even Aberrant Marisa describes as "truly terrifying," and she appears to be the central figure of the aberrant invasion.

"Ma... ma..." The aberration of Fujiwara no Mokou. She takes the form of a giant infant with a bird's beak, referred to as the Fledgling Form. Her lifespan appears to be only a few seconds... However, upon death, she is reborn into the Phoenix Form accompanied by a massive explosion. This form is a terrifying fusion of a Gashadokuro and a phoenix, featuring Mokou's characteristic hair and ribbons on the head. Even in this form, her lifespan is extremely short, but she triggers another massive explosion upon death, raining down bone fragments like a volcanic eruption. She then returns to the Fledgling Form, repeating a disaster-level cycle of reincarnation.

One of the factions of aberrations, known as the "Mad Children," consisting of fairies who have turned into aberrations. They lack intelligence and are violent, possessing the nature of fearless beasts, though there is some degree of individuality between specimens. Their appearances, abilities, and combat styles vary. Like the originals, they are immortal and will revive on the spot after a short time if killed. Their combat power is low enough to be brushed aside by the powerhouses of Gensokyo, with the exception of some high-tier variants. Against strong enemies, they fight using attrition tactics, leveraging their revival ability and overwhelming numbers. Since they can feel pain, they apparently prefer to avoid being forced into a "respawn" break if possible.

"Value!" The troublemaker of the Aberrant Fairies. Like the original, she has the power to manipulate cold air at will, firing freezing beams to turn her surroundings into ice. On land, she moves at high speeds like an ice skater by freezing the ground. Furthermore, unlike other Aberrant Fairies, she possesses automatic regeneration when damaged. She acts selfishly to show off her own strength and frequently clashes with her rival, Aberrant Lily White. Her frequent use of number-related words is supposedly a boast of her mathematical knowledge, though the meaning is entirely nonsensical.

Various other aberrations.

The original Yukari Yakumo. However, because she addresses the reader directly and is depicted interacting with Aberrant Reimu and other aberrations, her allegiance to Gensokyo is currently unclear. It is highly likely she has defected to the side of the aberrations for some reason.
