The adult anime series Oni Chichi Harem debuted on December 13, 2024. Noboru Amakawa is introduced in the first episode. He enters a deep forest after becoming disillusioned with life. He meets an unfathomably beautiful woman there. He loses his balance, tumbles off a cliff, and passes out because he is so stunned by her appearance. Upon awakening, Noboru finds himself surrounded by horned ladies who sexually abuse him repeatedly. He calls this environment a "breast paradise," overwhelmed by their advances and suffocated by their enormous breasts. Noboru learns that his virility is always active and keeps him aroused after consuming the breast milk from Daki, the village head. The celebration of Nyuuson fills him with joy. Blue Bread is the animator and Queen Bee is the producer of this episode. It is based on Momiyama's manga. The duration of the program is roughly twenty minutes.
