Set after the curse is broken. Emma and Regina have not gotten together yet.

This is a crossover with InuYasha.

Emma finds Tessaiga at Gold's shop wile Regina is talking to Gold a few feet away. She unsheathes the blade and the blade transforms.

Emma also transforms into a half dog demon as the blade has released recessive genes in Emma. Emma now has blond dog ears at the top of her head and has dog fangs. Her senses are heightened as well. More so her nose. And she seems to find that Regina smells intoxicating.

Now as a half dog demon, Emma has now become more possessive over what is hers, mainly Regina.

Tessaiga can only transform if the user has Yokai, demonic energy and cares for humans.
