Send me ♡ + a word, and I’ll write a headcanon.
For Hanzo, the three major dharmas to remember are Family, Duty, and Honor*.Fratricide(sorta) and his resulting reaction is what happens when the three conflict at the same time and are then put under pressure. You get a spectacular explosion.
Anyway, we’re just going to talk about family for now.
Blood Family: Off the bat I’m going to throw my hat in and say that Hanzo and Genji used to be really close brothers. For one, Genji still refers to his grown-ass brother as onii-chan when -san would have been more formal and just as acceptable which implies some degree of familial intimacy unless a) the honorific was used sarcastically or b) that’s just one of Genji’s quirks. Two, both of them seem to be holding onto these small seeds of hope that the other can be redeemed and converted to the other side of the conflict.
I honestly don’t have any real evidence for anything regard his relationship with his parents, but hey it’s headcanon for a reason. I feel as though Hanzo had to be around his father often to learn the ins and outs of becoming the next oyabun, but I don’t believe they had a close bond as father and son because of the additional status of being boss and subordinate. As the first-born he was groomed in the man’s image from the day he could walk, so I have my doubts that his formative years were filled with boding experiences that were unrelated to work. That being said, Hanzo doesn’t seem to harbor any kind of resentment towards his father.
The Shimada-Kai: The Shimadas are implied to be a syndicate within the Yakuza if not a DIRECT stand-in for the entirety of the Yakuza and as such, the motif of family comes up A LOT.(Calling higher/lower ranking members big/little bro & The Oyabun being referred to as father etc…) I feel as though Hanzo is super defensive of them because he actually considers them extended family regardless of being related to him by blood or not. Most of his father’s advisers were around him on the regular while growing up, so naturally he would grow attached to some degree. This loyalty is what makes Genji’s willingness to betray everyone even harder to look past in his eyes because that would be unfair to the rest of the family who lost everything.
