Onii-chan Boshuu Shimasu

The protagonist is a freeter. Job to job, gig to gig, he pays the debt his parents left behind in a life comprised of go-nowhere temporary work. "We're looking for guys!" says a flyer that catches his eye. Another day, another gig. He calls the number and is told to go at a certain location. That location is a lavish western-style house. Two pretty girls are waiting for him.
