The water kingdom and the death kingdom have been in a tough battle for a few years now.

The rulers seem to finally realize this battle isn’t going anywhere, and thousands of people are dying.

They now settle down to a peace treaty, an arranged marriage between the water prince, Tanjiro Kamado, and the death princess, (You).

Tanjiro waits for you in a calm manner in the wind castle halls, as they were now going to meet each other just two days before the marriage.
