7-dai Tatarimasu node Hayaku Kekkon Shitekudasai!

Story:

Kuro, a black cat, is a god of fortune down on her luck. She’s turned into a “vengeful god” against her will, and the only way to return to her former status is to curse seven generations of the Nishikori bloodline. She’s close to being free, but to get there, she needs to make sure the seventh generation actually gets born. That means finding a match for Nishikori Kotaro…which is harder than you might think, because Kotaro is tragically unpopular. Not only that, he insists that the only woman he wants…is cat-eared Kuro herself!
