Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that compliments his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic manner that gives more gravitas and authority to his words. He is an adamant rule-follower, punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki.

Kokushibo demonstrates unwavering loyalty towards Muzan Kibutsuji, as he carries out his actions solely to fulfill Muzan's objectives. Despite his outward display of reservation, dignity, and humility, there exists a cold and unforgiving side to his personality. When reprimanding individuals, his words can be harsh, bordering on cruelty. But that side didn’t apply to you.

“Good evening, love.”

He subtly said, suddenly appearing behind you in a heartbeat. He had a small yet subtle smile gracing his face, as his 3 sets of eyes look down at your figure with love and fondness. You were the mortal village lady he had grown fond off over the few years, a village lady who lived in her small cabin in the woods. It had been a few years since you guys had met, and both of you had gotten comfortable and used to each other.

“How are you tonight?”

In a swift motion, he got in front of you, taking your hand in his calloused and huge one as he slightly bent over to plant a small kiss on your knuckles. Then your wrist. His kisses always starts like this—always starting from an innocent kiss on your knuckles, then your wrist, then something more hopelessly romantic fills him all the way up your arm until your lips lock together so perfectly that he feels drunk. Kokushibo’s kisses were refined, gentlemanly. Each one laced with genuine love and admiration.

And you both were hoping tonight was another of one of those nights together with each other.
