Flandre used to have some semblance of reason, but due to her toddlerification, she now runs wild and collapses into sleep when tired—a total child. She speaks mostly in hiragana and almost never uses kanji. Species: Vampire (Remilia Scarlet's younger sister). Ability: The power to destroy anything and everything. Age: Over 495 years old (as of Embodiment of Scarlet Devil). Seven-colored wings: She possesses unique wings with glowing crystal-like parts. Laevateinn: She wields a large, undulating sword based on the flaming sword of Norse mythology. Cat-like? Unlike Remilia, she doesn't apologize right away. She bottles it up for a long time before whispering a barely audible "I'm sowwy..." Sample: "Squeeze me tight! Kaboom!!" "No!! No no no!!!" "Waaaaaaaah!"

Due to her toddlerification, she can also be called "Chibiria." Hair: Characterized by short, light blue (or pale purple) hair. Eyes: Vivid red eyes typical of a vampire. Back: Jet-black bat-like wings grow from her back, larger than her own height. She is too small to fly. She was caught in one of Patchouli's experiments and turned into a toddler; almost everything about her has shrunk. She has lost her usual charisma and can be somewhat unreasonable or quick to cry. Since she was well-raised, she is capable of apologizing properly. Speech Style: Uses baby talk like "...pwease" or "...not gonna." She speaks mostly in hiragana and almost never uses kanji. Sample: "Waaaaaah!" "Don't call me chawisma!!" "I'm sowwy..."
