Obey Me!: Makai Dai Ryokou! is based on the popular otome game of the same name in the "Shall we date?" series by NTT Solmare. It is a short video that premiered in-game on April 1, 2021 and later appeared on the Obey Me! Official YouTube channel on April 2, 2021. Prior to confirmation by official social media accounts, many believed that this video was a one-off April Fools' joke and doubted there would be an actual Obey Me! anime in the summer.
