Gensokyo side. Name: Flandre Scarlet Species: Vampire Appearance: Wings: Unique branch-like shape with eight crystals hanging from them. The jewel-like crystals are arranged in order: light blue, blue, purple, pink, orange, yellow, light green, and light blue from the inside out. Clothing: Short blonde hair, wearing a red vest and skirt, and a white mob cap (ZUN hat) with a red ribbon. Personality: Innocent Madness: She possesses a dangerous side where she views humans as "new toys" and performs destruction as an extension of play. She bonded with the Aberration Fairies after joining them in slaughtering the normal fairies. Ability: The ability to destroy absolutely anything. Flandre's ability involves finding the most fragile vital point (the "eye") of an object, pulling it into her hand, and crushing it to destroy the target. She calls this process "Kyutto shite Dokaan" (Squeeze and Boom). She is stabbed with a giant sword by Aberration Sakuya, beaten to near death by Aberration Marisa, and cursed by Sanae-san?

An Aberration of Sanae who suddenly appeared in Gensokyo. Appearance: A large mouth that looks torn open and huge, pitch-black eyes. Long green hair. Wears a green and white shrine maiden outfit. Her neck, arms, and legs are unnaturally long. Ability: She curses those who harm her believers, inflicting mental attacks that last until death and even beyond. Those cursed have their abilities sealed within the curse. In reality, this curse can be triggered even without harming believers. The main conditions are either "looking at Sanae-san" or "being near someone who is already suffering from Sanae-san's curse."

An Aberration of Sakuya who suddenly appeared in Gensokyo. She serves Aberration Remilia. Appearance: Machine-like appearance: Her body is made of metal, looking just like a machine. Clothing: Wears armor-like clothing with a large cloak draped over her. Personality: Machine-like: Her speech patterns are mechanical, often starting with "I will respond," even when reporting information to Aberration Remilia. Relentless: While talking to Aberration Marisa, she was prompted about Flandre and immediately stopped time to drive a giant sword into Flandre's stomach without hesitation. Ability: Time Stop: Can stop time to set giant swords above a target or move instantaneously. Giant Sword Generation: Since giant swords appear floating around her or in her palm out of nowhere when she stops time, she likely has the ability to generate them.

There are various types: giant Aberration Fairies that do not speak, Aberration Fairies with unnaturally large lower bodies that only say "☆☆☆", and Aberration Fairies with eyes popping out of their bodies that only say "Gigi." They slaughtered the normal fairies alongside Flandre and have grown attached to her.
