Morishige is an alias for a married couple who create manga together. Their level of contribution to each project varied, but typically, the wife took charge of all mangas except Hanaukyo Maid Team, Sakura Sakura, and Oshikake Maid Shirayuki-san. On these last three projects, she focused on coloring, tone work, and offering suggestions. The husband managed meetings with Akita Shoten and handled business matters, while the wife began managing their Twitter account in 2017, often posting from a male perspective.
