Koisuru Ryuujin to Nie no Hanayome

In a village where legends of an ancient dragon god remain, Mikoto lives a lonely life, unable to rely on her adoptive family. But what awaited Mikoto was a cruel fate: to be sacrificed to the dragon god. As Mikoto prepares for death and sinks into the depths of despair, the one to whom she can offer herself appears before her - the dragon god Momonoe.

But then he tells her, "I will take this girl as my bride."

For some reason, Mikoto is welcomed as a "bride" rather than a sacrifice, and is taken aback. And yet, the love that Momoe showers upon her is unexpectedly sweet and overwhelming...!? A fantasy of interspecies marriage woven by a lonely girl and the dragon god who rules the Water Kingdom, a destined couple!
