Nezuko can't speak, and Kanao rarely speaks-- maybe that's what makes their relationship such a slow burn. Trapped in her own mind, unable to speak, Nezuko develops feelings for one Kanao Tsuyuri. Unable to share them, Nezuko admires her beloved from afar. Unbeknownst to Nezuko, Kanao actually returns her feelings two-fold-- and while other slayers go on missions leaving Nezuko at the butterfly mansion, true feelings flourish. Nezuko fell first, Kanao fell harder. But there is one thing nagging at the back of each girl's mind; is it okay for a human and a demon to be like this? Is it okay for girls to be like this? Nezuko is taken away from Kanao for a short while on the Swordsmith Village Arc and wonders if Kanao still thinks of her. And when Nezuko finally stands her first day in the sunlight as a demon, her muzzle off and words escaping her lips, there is one thought occupying her; Tell Kanao.
