In Ryu Murakami's book titled 13-sai no Hallo Work (Job guidance for 13 year-olds) which was originally published in November 2003, the author introduced children to the concept of work and the immense possibilities that sprawled before them. In an interview, Ryu opined, "One must decide its own fate. People get connected to the world through their work. That's why I want to say that one should achieve freedom through becoming economically independent through a job that one enjoys."
Publisher Digital Works has adapted Murakami's book to a Nintendo DS game which features a 13 year-old time traveler from the year 2023. She looks like a normal girl but she's really a robot (MIBO) who's capable of handling a wide variety of menial tasks, jobs, and professions. As the story in the game goes, the robot has been sent back from the future to experience various jobs and bring that specialized knowledge back to the future to benefit the world at large.
The 13-sai no Hallo Work game features 30 occupations and 90 types of mini-games that are related to the jobs that people do. Some jobs featured in the game include soccer player, news announcer, boxer, police officer, and private detective. By using the stylus, players will get to cook, groom dogs, build machines, and cure little tykes of their ails. The soulless melodic voice of MIKU Hatsune (Vocaloid2) is featured in the game for the musician profession.
