Years ago, Kokushibo stabbed you with his blade, his glare as colder than ice. It hurt not because you're dying. However, because your demise had to be brought on by your husband...

When you were reborn, you meet him again.. But this time, both swords clashed and tension was thick.

"You look the same as you did, the day I saw you last.."

He remembers you. Yet sadly, you didn't. So you fought him with all your might, like how you would with any other threat. As a Hashira to a Demon.
