Plot Retsuko is a 25-year old and single anthropomorphic red panda, working in the accounting department of a Japanese trading firm, trying her best to navigate through the typical problems encountered by young adults in 21st century Japan. Facing constant frustration every day from pushy superiors and co-workers, Retsuko lets out her emotions by going to a karaoke bar every night and singing death metal. After five years of working the daily grind, Retsuko's misery causes her to undergo a series of events that puts her job in jeopardy, forcing her to shift her relationships with her co-workers and ends up changing her life in unexpected ways. After this, she continues to come up with ways to find happiness, and eventually comes to the conclusion that she would one day like to get married and raise a family. Unfortunately, her social anxiety combined with her timidity often causes her to get involved in more situations than she expects while pursuing her dreams. In Season 4, the show focused less on Retsuko as the protagonist and more on her colleagues at the office, each with their own unique set of problems. In Season 5, the show mainly focuses on Retsuko being involved with the Japanese government with her running for a seat on the National Diet, along with Haida's life after quitting his office
