One day, he is asked his uncle to start a relationship with his cousin Mashiro Tsukinomori in exchange for him providing support for his game development group, which they call the 5th Floor Alliance. Meanwhile, Iroha aims to be a professional voice actress, providing the voices for the 5th Floor Alliance's work, but does so in secret due to her family's disapproval of her interests.
