Mashin Osakabe
Gender: Female
Zodiac: Scorpio
Blood Type: A
Though she used to be an assistant to Shinjo Mayu, she has since then stuck it out on her own. Her style is different than that of Shinjo Mayu in that it is more graphic. Her art style is completely different than that of Shinjo Mayu other than the fact that they seemingly enjoy having the main male characters of their series look like a character from another one of their series. And all being hot bishies.
