Aki is a second-year student in Kyōya Hashiba's Department of Film who is commonly known as "Shinoaki". As of 2016, she was working as a famous illustrator under the name Shino Akishima, whom Kyōya adored.

Along with Kyōya, she went on to belong to the Art Society. While living as a student with Kyōya, she gradually became a favor with Kyōya. After developing a doodling game, she fell into a slump, but at Kyōya's recommendation, she began to demonstrate her amazing talent while working on illustrations with the addition of the Kuroda-ji.
