Kongiku's Links
Kongiku views Mizuki as the brother of his master. He does not enjoy that the man is very strict and equally doting of his master. He thinks that Mizuki is just a big nagger and kind of a killjoy to his fun and games.
Mizuki is very harsh on Kongiku but mostly because of his high expectations for the familiar to defend his brother. While he does not approve of the slothful ways of the fox, he is still very caring towards Kongiku and only wants the best for both him and his little brother. Even despite Kongiku's unappreciative demeanor towards his strict upbringing of the two.
Kongiku finds Daiki annoying because he is too "stiff" and too S T E R N. It is quite frequent that the fox will try to sneak himself and Haruki away from Daiki's presence but for some reason it doesn't seem to be hard for the man to find them both much to Kongiku's dismay...
Kongiku greatly appreciates Haruki's care for him. He holds his master in high regard due to the patience and love that he has bestowed the ornery fox. He cares deeply for Haruki and would fight to the death, not because of the contact but because he considers the boy his family and wants to put a smile on his face (though frequently only tries with minimal effort).
Haruki cares for Kongiku greatly and views him as a family member, and he does his best to take care of the fox, reining in some of the more impish impulses, while also doing his best to be a good master. Haruki can of course get fretful, irritated, and upset when Kongiku is being very rude and/or lazy, but still loves him lots and lots!
