Mika Amanashi (雨無 美香, Amanashi Mika) is a high school shōjo mangaka just like Roman. She is supposed to be Roman's rival, but later she becomes Roman's friend. Her manga drawings are better than Roman's, but the plot are crappier. She got her pen name, Mikan, from Roman who often called her by that name.
