Ryujirou Mine

About

A critically acclaimed author who can sell ten million copies of his manga once it hits print, earning him a spot in the Ten-Million Club. He briefly hired Kouta as an assistant, but quickly fired him following an ink spill that ruined one of his pages, claiming he does not have what it takes to be a manga author and explaining to him the realities of the manga industry.


It is revealed by Izumi that he was a former employee of Comic Splash, and was Hinata's disciple. Hinata gave Mine his big break on his debut manga "Farewell, Tokyo" which sold 30 million copies, which in turn led to the spread of numerous rumors by her competitors.


It is later revealed that Hinata (who was a manager at the time as well as his editor) had collaborated with him on his debut work.
