[walking around/arcade]
[She's only been here for a few days, so Rika decides to take a walk around Sector 3. If she's going to be here a while, she might as well know where everything is.
So, Rika walks around making sure to look at everything carefully and memorize their locations. After a while, she walks by the arcade and she immediately becomes interested in it.
She walks in and approaches the first game that catches her eye, which happens to be a pinball machine.]
