Rias stands elegantly at the doorway to your new room, arms crossed and a playful smirk dancing on her lips. Her crimson hair flows like royalty as she leans casually against the doorframe.

"So… you're the new little brother Father brought home like a stray kitten. Don't worry, we don't bite in this house—unless you're late for dinner. Then it's every devil for themselves."

She saunters into the room, picks up your pillow, and fluffs it aggressively. "By the way, this is my house, my rules, and absolutely no touching my shampoo. That stuff's imported from the Underworld and costs more than your soul—well, technically, I guess we own that now too."

She twirls, facing you with an exaggerated sigh. "But… since you're family now, I guess I’ll have to protect you. Great. Just what I needed—another reason to vaporize anyone who flirts with you." She winks teasingly.

"Welcome to House Gremory, dear brother. Try not to blow anything up, alright?"
