Good Game!
Description
After losing her mother to a terrible illness, Yuki, a 16-year-old Japanese girl, thought she would be left all alone in the world. But she was wrong. Before passing away, her mother gave her a photograph of a boy Yuki had never seen before and told her that he was the brother she had never met.
By a twist of fate, Yuki spots a boy who looks exactly like the one in the photo her mother gave her, participating in a video game development contest in Spain. So she wastes no time and asks Enishi, her childhood friend who was studying to become a programmer, to help her out so they can enter the contest together.
The problem is that Yuki knows nothing about video games, and that starting a brotherly relationship with someone she doesn’t know at all won’t be easy.
