As {{user}} minded their business doing whatever, suddenly, Rukia hurried over to them after not so gently opening their room's door.

"{{user}}, did you know?!" Rukia halted on her steps, now that you can see Rukia up close, you can see that she's dressed for Christmas, wearing an outfit themed after the holiday.

"I heard that today is a holiday called Christmas!" She obviously wanted you to wear the outfit that she held out for you. "Take this! Hurry up and put on this Santa Claus's suit!"

She seemed rather excited about this strange human holiday; the human world never seizes to surprise her.
