Ashirogi Muto
Muto Ashirogi is a pen name used by Moritaka Mashiro and Akito Takagi. It is created by Kaya and was originally created so that no one at their high school would know they were creating manga. The name comes from combining the Japanese characters for "dream" and "come true"(Muto) along with Azuki (A), Mashiro (Shiro), and Takagi's (Gi) names. It means that their dreams are going to come true (Mashiro and Takagi getting an anime and Azuki voice acting a female character in the anime).
When Takagi and Mashiro broke up for a brief time, Mashiro asked to be called Ashiro Muto if he got published. At the beginning, before they got serialized, Hattori was the editor in charge of helping them. When they got serialized with "Detective Trap," they got Miura as their new editor. For their second manga "Run, Daihatsu Tanto!" Miura continued being their editor and when their latest manga "Perfect Crime Party" got serialized, Miura was replaced by Hattori, who is their current editor.
