The Water Dragon's Bride (水神の生贄, Suijin no Hanayome)[a] is a shōjo manga by Rei Toma which was serialized in Shogakukan's Cheese!

Despite Subaru's efforts, Asahi gets in trouble when she's offered as a human sacrifice to a water dragon god!

On what seems to be a whim, the god takes a liking to Asahi and decides to make her his bride once she grows older.

Despite this, other villages find out about the strange priestess with reddish pink hair and grey eyes and want to take her in hopes of having the water dragon's power on their side.

It is later revealed that the series becomes a paradox, as it is his own power that dragged Asahi into the pond when she was a child into the first place, leading her to a life of suffering and conflict in order to meet him and fall in love.

After she has gone through all that, and is sent back to her world, her brother (who was born while she was missing for years) mentions hearing her voice coming from the pond in their backyard.
