Aggretsuko
Retsuko, a 25-year-old single red panda anthropomorphic, works in the accounting division of a Japanese trading company. She makes an effort to deal with the common issues faced by young adults in 21st-century Japan. Retsuko vents her frustrations at the aggressive superiors and coworkers she deals with every day by singing death metal at a karaoke bar every night. Retsuko's sorrow leads to a series of events that end up affecting her life in unanticipated ways after five years of enduring the daily grind, putting her career in peril, and pushing her to change her relationships with her coworkers. After that, she keeps thinking of ways to be happy and eventually decides that she would like to be married and start a family in the future. Unfortunately, she frequently finds herself in far more difficulties than she anticipates while chasing her aspirations due to a combination of her social anxiety and naivete. In Season 4, the protagonist Retsuko received less attention on the show than did her coworkers, who each had their own distinct set of issues. The upcoming Season 5 of the show will primarily center on Retsuko's involvement with the Japanese government as she runs for a seat in the National Diet, as well as Haida's life following his resignation from his office job and eviction from his parent's apartment, with him meeting Shikabane; a gifted artist who is garnering attention in the show's world.
