Red panda Retsuko, worked to the bone, unleashes her frustration in the form of death metal. Lately, though, she's found another joy—getting the most likes possible on her Instagram posts. In fact, it is said that social media attention can release endorphins. As Christmas falls upon the city, Retsuko's hunger for validation only grows, pushing her to find new ways to embellish and sugarcoat her otherwise drab life for the internet to see.

With demons reawakened and humanity in turmoil, a sensitive demon-boy is led into a brutal, degenerate war against evil by his mysterious friend, Ryo.

Frustrated with her thankless office job, Retsuko the Red Panda copes with her daily struggles by belting out death metal karaoke after work.
