Over time some Kitsusagi may fall in love and want to expand their family. That is great! There are a couple of things that are needed for breedings. First you need a item called a Heart Stone. Once you have that then you will need to create a Breeding Agreement between the Kitsusagi you wish to breed. The Heart stone will be purchasable at Cresent Curios. Once you have these items you will then need to submit a claim with the Kitsu, the Heart Stone, and any breeding items, as a claim.
