When I first discovered the show, I didn't know the name. So, when I went to try and watch the next episode I googled..."anime with cute lazy girl who plays video games and lives with her brother" It was the first thing that popped up under the searches.
That is basically what the show is about. It's cute and funny (and a great time eater if you're waiting on someone)! I think I read somewhere that there might be a game based on the manga/anime coming soon (it might already be out).
