Seri Tainaka, writing under the pen name Nanakusa, is a mid-career manga artist living in the shadow of her only one-hit-wonder. Her series “To Hell and Back” was adored by fans, but despite now being a ten-year veteran, her successes ended there. So when Seri is told that she is being assigned a new editor, it only fuels her insecurities. When Seri meets the quirky Sumire Futami, she’s both creeped out and captivated by the strange and overly forthright woman, who claims she’d go to hell and back to make her a success again. But just when Seri starts to think she and Futami might be an unstoppable duo, she meets the other manga artists Futami is assigned to, and a dangerous game of jealousy, envy, and femme fatales begins.
