葉木莉さんは君だけの死神になりたい, Hakirisanwa Kimidakeno Shinigamini Naritai

Futagami is an ordinary high school student who wants absolutely nothing to do with love—let alone marriage. But one day, when he opens his front door, he finds a literal grim reaper standing there—complete with a skull mask and a giant scythe! Her name is Hakiri, a reaper from the spirit world who’s come to ensure his death. The catch? His foretold cause of death is the first-ever case of death by marriage. When Futagami insists he has no romantic prospects, Hakiri responds, “Then I’ll be your bride.” Thus begins a shocking "marriage equals instant death" romantic comedy!
