Miho is a shy girl with the ambition to become a successful seiyu (voice actress). While her reasons and motivations to become a seiyu are unclear, it was an ambition that was reinforced by the ambitions of Ashirogi Muto. Both she and Moritaka Mashiro fell in love with each other at a very young age. Although they both had mutual feelings for each other, they're also mutually very shy and embarrassed in the matters of love. It wasn't until Moritaka was encouraged by Takagi to announce their publishing ambitions to Miho that he accidentally blurted out his desire to marry her if they become successful. Although shocked at first, she happily agreed to his proposal: they'll get married when she becomes the leading seiyu in his manga that will become animated.
