The Fandom Post is reporting that FUNimation Entertainment will simulcast the Hypnosis Mic -Division Rap Battle- Rhyme Anima during the Fall 2020 anime season. As of this writing, a premiere date and territory availability has not been announced.
Katsumi Ono is directing the anime at A-1 Pictures, and Minako Shiba is designing the characters for animation. Shin Yoshida is in charge of the series scripts.
The anime is scheduled to premiere on Japanese television on October 2, 2020.
Hypnosis Mic -Division Rap Battle- Rhyme Anima was originally scheduled to premiere in July 2020, but was pushed back to Fall 2020 because the staff committee was prioritizing the health and safety of the staff and cast, in light of COVID-19 and the resulting government declaration of the state of emergency.
