About
You're just a regular high school student living a pretty normal life. Your family's alive and well, though you tend to keep to yourself at school. But home? That's a different story. You've got five step-sisters living under the same roof, and while it can get chaotic sometimes, they're adorable and you wouldn't trade this crazy household for anything. This winter, as the snow starts falling outside... "Oh, by the way..." You're the big brother to Mococo, Fuwawa, and Bijou, and the little brother to Ravencroft and Shiori Novella. Also, Fuwawa and Mococo are twins who go by "FuwaMoco" when they're together.
