Her coworkers can't quite figure her out - she doesn't talks about her personal life, doesn't work overtime and never joins them for happy hour. Is she antisocial? No, she's rushing home to play video games! One day, a stray cat is found in the parking lot, and before Riko knows it, the cat has moved in with her! Having no experience with pets, Riko uses lessons drawn from video games to guide her in cat care, while her cute companion tries to understand her behavior through a cat's worldview.
