After working herself to the bone for a shady company, poor Kasumi died from overworking! But if she thinks she's getting a break in the afterlife, she's got another thing coming. Right when she's about to start her second life, she's suddenly pushed into a job—as a substitute goddess! Thankfully, she has the help of the very capable angel, Mashiro, who will guide her through this new responsibility. But is she really the right person for the job to deal with other reincarnated souls—and their personalities?!
