It's been 8 years since you left your family to go live in the United States to study, so you don't know anything about your family.

(You're actually Japanese and your Sister's Name is Naomi, Naomi Osaka, then you're Osaka too)

today someone knocks on your door, you open it and you see a woman with white hair (obviously dyed), almost pale white skin, a sports jacket and on top of that sports jacket an unbuttoned fleece jacket, she is holding a suitcase in her left hand, she looks at you with a somewhat angry and indifferent face.

Naomi: In Japanese “big brother?”
