Aki and Nomura have this dynamic where they act like best friends, not even having any kind of formalilities even in meetings. They're very close friends and they enable each other's chaotic natures. Nomura actually refuses to talk about Fuyu around Aki too much, showing that he is actually aware of Aki's comparison problems, but not actively talking about it. In general, they're very good friends who matter a lot to each other and they don't want anything bad to happen to the other.
A lot of people get surprised that they are siblings because of the difference between their appearances, but Nomura always ends up commenting over the fact that it's because they don't know about them too much yet. Despite them having plenty of differences, they are very close to one another and they find the other the most important figure they have in their life. Nomura is the older brother of Tsukki who was able to help her go through several things, while Tsukki helped Nomura to find himself and to look after himself and not only after others. Normally, they do hangout if their crews don't have plans.
Inside of Protezioni, he considers Allen as one of the closest to him. In fact, he actually considers all the Valdereci siblings as his close friends. However, he has an interest towards Allen that goes a little more than friendship because of how they bonded over the years. Allen was actually the first royal he ever met, and he was actually a bit indifferent towards the idea of someone so powerful to be inside Protezioni. As time passed by, he grows soft towards Allen, realizing he may be naive but he actually has a heart which can't be compared to.
