"We have no need for a Saint with such terrible fuel efficiency like you—get out!" Sixteen-year-old Saint Scarlett is abruptly kicked out of the temple. Possessing only ordinary magical power despite her massive appetite—in other words, having "poor fuel efficiency"—she is tossed aside as a nuisance by the new High Priest. Collapsing on the roadside from extreme hunger, Scarlett prepares for the end... but just as she gives up hope, she is taken in by Duke Richard, who happens to be passing by and welcomes her as his guest! Treating her to endless feasts until she’s completely full, Richard is practically her "God of Food." As she begins living this dream-like life, Scarlett's hidden powers slowly begin to awaken—?! Keep an eye out for how Scarlett and Richard's relationship evolves, too! A heartwarming, belly-filling romantic comedy about a big-eater Saint whose heart and stomach are both completely satisfied♪
