Straker Yuuta’s mother is in prison. His father skipped town after swindling money from the entire community. Straker was left as a young child to be raised in an orphanage. Throughout his childhood he was exposed to the hatred and resentment of everybody around him. And the community happens to be very isolated and very poor and on the Moon.
When Straker is old enough to strike out on his own, he leaves his hometown behind and joins a long range asteroid-mining mission. He expects to find riches. What he encounters is much more than he ever expected.
