When her patience reaches its limit, Retsuko resorts to her preferred form of emotional release: death metal karaoke. Five years later, her corporate enthusiasm has been worn down by a grinding combination of a tiny apartment, a crowded commute, a real murderer’s row of co-workers (a gossiping hippo, an appearance-obsessed deer, a sociopathic fennec fox), and a chauvinist hog (literally, he is a pig) of a boss. When Retsuko, a red panda fresh out of university, finds an office accounting job, she’s brimming with optimism. Based on one of the many characters by Sanrio, a Japanese company known for its cute merch centered around personality-driven animal cartoon characters (Hello Kitty, anyone?), Aggretsuko is basically branded content, but it’s good branded content.
