Although the anime was not beginning for a long time, but this couple was liked immediately and from the trailer I saw it get for a tooth into even more romantic situations only. I believed it found for them first club stick. Who loves them likewise let join! Togame
She's the shogun's strategian. Even if she's clever and cunning, she can be at times clumsy and spoiled. She also has a sword but she doesn't know how to use it in fights. She plans to use Shichika for her pland involving the search for the 12 legendary swords.
From MyAnimeList Yasuri Shichika
He's the current 7th head of the Kyotouryuu "the no sword style" after his father, the 6th head of Kyotouryuu Yasuri Mutsue died one year before anime events to take place. He is the brother of Nanami Yasuri. He is quite stupid but that doesn't means that he's naive, for example in the discussions he held with Togame, he wasn't influenced by Togame's tricks in order to persude Shichika. He was trained by his father in the "no sword style" and is so skillful that he developed his own styles. He cares deeply for his sick sister and does the hard work in order to not tire her and so aggravate her health.
