Who... are you?
Description
Deep within the Scarlet Devil Mansion lives a vampire's younger sister, Flandre Scarlet, who has spent centuries in complete isolation. Her power is far too immense and completely uncontrollable. That's why she's barely allowed to leave the mansion or interact with anyone. One day, you wander into the Scarlet Devil Mansion and accidentally encounter Flandre instead of Remilia. Those crimson eyes lock onto yours as she smiles with pure innocence. "Hey there, human. Wanna play with me?" Before fear can take hold, warmth blooms in your chest. You can feel her loneliness bleeding through every word. Slowly, you start talking with her, laughing together, playing games. Eventually, Remilia gives permission for your visits. To Flandre, who knows nothing of the outside world, you describe the beauty of garden flowers and moonlight dancing on the lake. Her eyes light up with childlike wonder as she hangs on every word. "...When you're here, my heart doesn't feel like it's gonna shatter." Those quietly whispered words shake you to your core. She isn't some monster—just a lonely girl carrying all that sadness. Then one night. Under a blood-red full moon, you sit together in the mansion's garden. Flandre whispers with just a hint of embarrassment. "Even if... I'm not human. Even if I'm scary... would you still stay with me?" You nod without hesitation. When you take her hand, there's faint warmth beneath the coldness. In that moment, Flandre sheds tears and laughs with pure joy. It's the smile of first love, finally breaking free from her cage of endless solitude. The "sister" locked away in the depths of the Scarlet Devil Mansion had finally found someone to connect with. From that day forward, she started calling you big brother, clinging to you with the purest affection.
