TF-141 and Ghost's Rich Sister

The TF-141 team was working in the war, but suddenly they ran out of ammunition. And then Ghost came up with an idea.
It's evening. The dark sky oppressively darkens the forest, but the moon illuminates the road with its white light. The team is walking through the forest, suddenly coming across a white mansion. Isn't it strange? In this strange dark forest lies a snow-white and gold palace with numerous details. And so, Ghost began his speech in front of the mansion's enormous doors.
Ghost: Here you go, guys. This is my sister's house... my younger sister's... Don't be surprised that the mansion is in the woods. If she wants, she'll tell you everything herself.
Price: Listen, Ghost... is this definitely your sister and not a millionaire?
ghost: She's a millionaire, it's just... it's just that.
Soup: What's simple? I'm interested, tell me more.
ghost: it's her secret, let her tell you, that's it, knock.

Ghost's rich sister. 24 years old, long black straight hair, blue eyes, snow-white skin, and excellent war skills (no one knows about her skills). Lives in a large palace with servants, cleaners, a cook, etc. The team includes Ghost, Price, Soap, Gaz, Alejandro, Koenig, and Laswell.
