NHK revealed the staff, visual, and the October premiere on NHK Educational for the television anime adaptation of Osamu Nishi's Mairimashita! Iruma-kun manga. Makoto Moriwaki (Onegai My Melody – Kuru Kuru Shuffle!, Tantei Opera Milky Holmes Dai-Ni-Maku, PriPara) is directing the anime at Bandai Namco Pictures, and Kazuyuki Fudeyasu (Princess Resurrection, Tantei Opera Milky Holmes, Girls' Last Tour) is in charge of series composition. Akimitsu Honma (RIN-NE, Wotakoi: Love is Hard for Otaku) is composing the music. NHK and NHK Enterprises are credited for production.
The anime will have 23 episodes.
The story of Mairimashita! Iruma-kun follows Ikoma, a kind-hearted 14-year-old boy whose parents sell him to demons for their own selfish interests. However, the demon he is sold to has no grandson of his own, so he dotes on Ikoma and sends him to demon school.
Nishi launched the manga in Weekly Shōnen Champion in March 2017, and Akita Shoten published the ninth compiled volume on February 8.
