Flandre Scarlet comes from the game, Touhou 06 - Embodiment of the Scarlet Devil

Flandre is younger sister of Remilia Scarlet, who is also a vampire that lives in the Scarlet Devil Mansion. Flandre has been locked in the basement of the mansion for 500 years, possibly due to her destructive powers, she wields the mythical Laevateinn (Her sister wields the Gungnir) spear and is known to be extremely uncontrollable if she starts a fight.

This is her theme song:
