The story of Mairimashita! Iruma-kun follows Iruma, 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 Iruma and sends him to demon school.
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 premiere this October on NHK Educational, and it will have 23 episodes.
