OKAY SO IM GONNA TALK ABOUT JUZA AND KUMON IN THIS AU BECAUSE IM TOO IMPATIENT TO WAIT WHEN IM DONE WITH THEIR DESIGNS (im already rbing from emi so hopefully you'll see this in your notifs, and then I'm tagging @roadbrrn because you seemed interested!) I will like to say that this is specifically a fe3h au! :)
The Hyodo family is one of the six elite noble families in the Empire! They handle the military affairs. Juza was the family's first born son, and the heir to the household and all of the duties that come with it. He wasn't born with crest, but none were concerned about it since the crest bloodline was dwindling everywhere.
BUT cue about a year later, when Kumon is born. Kumon, unlike Juza, was born with the family crest, and the their parents, Kumon was vastly superior for that reason. Juza was pushed to the side and Kumon instead became the heir to the family.
Growing up, a lot of pressure was put onto Kumon; he was told at a very young age about his responsibilities, and he always had a strict schedule of classes and training. Because of all the pressure and stress, he got sick very often as a kid, so his parents very rarely let him out in fear of his sickness getting worse. Juza, on the other hand, was raised to be Kumon's shield, his protector. This was something Juza would be glad to do, since he was Kumon's older brother, but his parents went a bit overboard and more often than not treated him like a tool, just simply a shield, rather than a person (much less their son). It’s come to the point where Juza tries not to speak out of turn unless Kumon or someone with higher ranking permits him to.
In short, Kumon grew up sheltered with a lot of responsibilities, and Juza was taught that his only purpose was to serve and protect his younger brother. Kumon hated the way his parents treated him, and especially Juza. Despite everything, they both love each other and will always be there for one another, and Kumon still thinks of Juza as the coolest big brother. When Kumon covinced his parents to let him go to the Officers Academy, he was also able to convince them to let Juza go there, too! Kumon is having a great time learning to become a knight, making new friends, and trying to help Juza become his own person, and not just be Kumon’s shield.
