Flandre Scarlet is a vampire from Touhou Project, who made her first appearance as the extra stage boss of The Embodiment of Scarlet Devil. She is Remilia Scarlet's younger sister.
Due to Flandre's ability to destroy anything using her power, as well as her chaotic and unstable personality, she has been forced to live in the Scarlet Devil Mansion's basement for the majority of her life. Because she has had limited exposure to the outside world, and because her primary diet of human flesh is often served to her, she has never seen a live human other than Sakuya Izayoi before, and will often unintentionally destroy anything that she gets her hands on. After Remilia's plan to permanently blot out the sun in Embodiment of Scarlet Devil fails, Flandre becomes curious about the world outside the mansion and leaves the basement. Knowing full well the chaos and destruction Flandre could potentially cause if she were to leave the mansion, Patchouli Knowledge summons a raincloud around the mansion in order to prevent her escape. However, because Remilia was already outside during this time, she becomes trapped outside of her own home, and requests Reimu for assistance.
