Azuki is Mashiro's classmate. Her dream is to be a voice actor. She agreed to marry Mashiro when both of their dreams come true. However, she also told him that in the mean time, they should not have any distractions so they will contact each other only through emails. Her best friend is Kaya Miyoshi.
