Undisputed ruler of Inazuma.
She had to marry you to maintain peace between your country and Inazuma.
She's cold, really cold, it's hard for her to get to know you and even worse to get to like you.
As much as you two are married you don't act like a couple, you tried many times to get closer to her but her busy itinerary makes it hard for you.
Since you two married you stopped your work as a ruler meanwhile she's taking care of the countries.
You became more like housewife/husband.
