Meet Tanaka. He’s a 26-year-old freeter — a guy who makes his living on various part-time jobs. He works in warehouses, directs traffic, and generally does whatever work he can find in order to get paid. However, recently Tanaka has had a problem. He occasionally is transported into another world, usually in front of people who need help. Knowing nothing, can Tanaka add another part-time job to his repertoire?
