Rainbow Fruit Salad
Flandre's Social Club outfit of destructive cuteness. It was created by Kourindou with materials from Yukari.
Vampire Making a Wish
Flandre's furisode for the New Year. She makes a wish that she and her big sister have lots of fun this year.

Sekki (a Touhou LW original) refers to auroras as they were referred to in old literature. An aurora's rarity and flickering red waves are similar to Flandre. Perhaps because of her non-Eastern origins (or maybe just because of her transcendental way of thinking), Flandre's temperament deviates from the usual laws of Phases and Essences. She is weak against Sun Essence with its governance of day, Water Phase with its barrier properties against vampires, and Wood Phase with its legendary use in defeating vampires. She is strong against Moon Essence and Star Essence with their governance of night as well as Metal Phase with its position as a symbol of universality.
An incredibly threatening ability, as the name suggests. Flandre once used this ability with Remilia to destroy a meteorite aimed at the Scarlet Devil Mansion. The range of the ability, how it destroys, and the cost for using this ability is not clear, but apparently, every object has something called an "eye" which is where its tension is highest. By moving this eye into her hand and squeezing it, Flandre is able to destroy the object the eye belongs to. Just hearing about this ability is enough to make anyone's chest feel tight.
Flandre Scarlet's Spread Shot (a Touhou LW original). Flandre created this shot based on Starbow Break so that she could play with the fairies at the lake. She came up with the name after Sanae saw her practicing the shot and said that it looked like an electromagnetic specter.
Flandre Scarlet's Focus Shot (a Touhou LW original). Flandre made this shot based on Forbidden Fruit so that she could have battles of bullets with Marisa and the others. She came up with the name after Patchouli, who had been supervising Flandre's training, suggested that Flandre use the name of the tree of life, since the shot was based on the forbidden fruit.
Flandre Scarlet's Spell Card. She traps her target within a ring of bullets, only to shoot more bullets at them. Perhaps it overlaps with Flandre's own situation of having been in the same room for 495 years. Incidentally, this attack has the danger of becoming impossible to control, which might be why it is taboo.
Flandre Scarlet's Spell Card. She rotates a long crimson pillar of light and uses it to attack. Apparently, it is a counterpart to Remilia's Gungnir. Laevateinn is a weapon from Norse mythology―perhaps Flandre enjoyed some Norse myths during her long time indoors.
Flandre Scarlet's Last Word (a Touhou LW original). She created this bullet hell attack based on Spell Cards like Ripples of 495 Years in order to enjoy her battles of bullets more. Marisa gave the attack its name by comparing Flandre to a black hole after reading astronomy books from the outside in the Scarlet Devil Mansion's library.
Something unknown and different dwells within Flandre's eyes. You cannot stay calm with her gaze on you.
Flandre acts without malice and with only pure motives, but all she leaves in her wake is destruction.
Everything has an "eye", the spot that is under the most tension. Once she finds the "eye"―it's over.
