The Netflix TUDUM Japan event announced a fifth season of Sanrio's Aggressive Retsuko (Aggretsuko) net anime series on Sunday. The final season is scheduled to premiere worldwide on Netflix in February 2023.

The first anime adaptation based on Sanrio's titular red panda mascot aired in 100 one-minute episodes from April 2016 to March 2018 on TBS' Ousama no Brunch program. TBS subsequently combined all 100 episodes and broadcast them in 10 episodes.

The first, second, third, and fourth season streamed exclusively on Netflix worldwide in April 2018, June 2019, August 2020, and December 2021, respectively. A Christmas special titled Aggressive Retsuko: We Wish You a Metal Christmas debuted in December 2018. Rareko returns to direct and pen the script at Fanworks.

Synopsis
Some offices have stereotypical dynamics: the chauvinistic pig of a boss who never does any real work; the employees whose goal is to suck up to the boss; the ones whose lives seem perfect; and the individuals who have all the actual work pushed onto them. Retsuko the red panda is in the last group, as she stays late most nights to make up the work her coworkers are too lazy to do themselves.

Her relief from the stress of her everyday life comes in the form of singing death metal at a local karaoke club. Night after night, Retsuko channels her grief into a microphone and considers the place to be her own personal sanctuary. But as she moves further away from her comfort zone and the ideas people have of her, she discovers that letting others into her world of death metal may not be such a bad thing.
