Send a 👫and I’ll write four headcanons I have about our muse’s relationship
Daki knows that Gyutaro, even though he now takes pride in his ugliness, has bad days where he feels self-conscious or less than compared to other men.. so she makes it a point to tell him that he's perfect and that at the end of the day, his little sister adores him; and she would rather have him over any 'stuffy rich bastard'. After all, together they can do anything.
Although Gyutaro is obviously the brash bodyguard of the pair, Daki has a habit of checking on him if she hasn't heard from him or felt his presence at least once during her time being awake and active. If she's feeling extra lonely, she'll venture out and find a big strong human to give her brother a good meal. It's her love language.
Because of her brother, Daki thinks things like spiders and snakes specifically are cuter than the standard small furry creatures. He taught his little sister not to be afraid of them, and that they were important they helped to keep the pests out and their home clean. Sometimes, if she finds a particularly big or beautiful one, she'll ask Gyutaro to come and look at it with her.
Gyutaro helped his sister to develop her 'lady-like' manners while they were both children. He knew that Ume had a future that would allow her to have a better life, but she needed to climb the ranks of courtesans and escorts. Which meant she needed to nail down the elegant mannerisms and poise of a 'proper lady' while they had time together. In meals, in conversation, and even in walking practice and how to dress.
