The third compiled book volume of Nanatsu Mukunoki 's Watashi ni Tenshi ga Maiorita! (An Angel Flew Down to Me!) manga revealed on Friday that the series is getting a television anime adaptation. An official website for the adaptation also opened to reveal a teaser visual and the anime's main staff.

The anime is reuniting staff members who worked together on the New Game! anime. Daisuke Hiramaki (episode director for Yuruyuri San Hai! , Shirobako , New Game! ) is directing the series at Doga Kobo ( Tada Never Falls in Love , Monthly Girls' Nozaki-kun ). Hiromi Nakagawa (chief animation director for Himouto! Umaruchan , Rewrite ) is designing the characters, and Yuka Yamada ( Miss Kobayashi's Dragon Maid , My Sweet Tyrant ) is in charge of series composition.

The four-panel comedy manga's story centers on Miyako Hoshino, a shy college student and otaku . Miyako's younger sister Hinata, who is a fifth grader, has a classmate and friend named Hana. When they meet, Miyako falls for Hana at first sight.

Mukunoki launched the manga in Ichijinsha 's Comic Yuri Hime magazine in 2016, and the publisher released the second compiled book volume in November.
