Oreco Tachibana got her start as an artist in 2016 when she began posting her acrylic paintings of landscapes on Twitter. While taking care of her children, she developed a following by self-publishing manga projects and illustrations on Pixiv. Before long, she caught the attention of key players in the professional manga world and published her debut one-shot, "Shunin-sama to Shinjin-kun" (Supervisor and Newcomer), in 2017. The following year, she launched Promise Cinderella, her first serialization. Her follow-up project, Firefly Wedding, began serialization in 2023.
