It's okay, I understand if you didn't know when you made the article. Honestly, I don't think you can seal dragons into a person, as dragons are physical creatures. Tailed Beasts can be sealed inside people because they are nothing more than massive concentrations of sentient chakra, as opposed to dragons, which are flesh-and-bone creatures that possess chakra. Chakra can be sealed, living things, as far as I know, can't.

As for suggestions, perhaps Yamiyoryu can be a malignant personality of Amaya's that can take on the form and abilities of a dragon, similarly to Yakumo's Ido monster in the anime? Perhaps this creature resided in one of the members of the Mizuno clan long before your series started and was extracted and sealed into various people.
