... right so who wants to hear my deranged theory about Yuri Tokyo Debunker with no evidence backing it up I believe only as a joke.

The mutual mommy issues and classical music interest made me think that Yuri and Jin could be related. A lot of Yuri's... yuri-ness screams second child syndrome, I couldn't find where or if it was even said but Yuri seems to indicate he was raised to be a doctor. We know Jin's dad is the head of the entire institute, the institute also has a medical branch. Based on what we know about Jin's dad he seems like the old school political dynasty sort, if he had two sons raising one to take over the Institute and the other to oversee its medical branch makes a lot of sense. It would also make sense for Yuri, as the baby of the family, to maybe be closer to their mother than Jin was. If Jin was expected to take over for their father, it makes sense for his dad to monopolize his time and not allow him to spend as much of it with his mom. Yuri could have spent almost all of his time with her, and if Mama Kamurai was particularly sickly (or cursed) Yuri's interest in becoming a doctor becomes extremely significant. It is clear both Yuri and Jin love their mothers, whoever they are, but if she was the same woman their hatred for each other can be explained by a sibling rivalry. Jin resenting Yuri for being mommy's "favorite" and h Yuri hates that Jin is daddy's favorite and gets all the money to do whatever he wants with while he's stuck writing expense reports for his vital research. Jin could even be blaming Yuri for being unable to save their mom, it certainly seems like Yuri is blaming himself already.

If this was the case, I think whatever injury Jin has sustained probably was the breaking point between the two. Yuri probably doesn't want to lose his brother, he seems like the sort who would really desperately want big brother's approval. If Jin turned his help away in disgust then of course that would nuke the relationship between the two dorms. If Yuri really was just Jin's younger brother (oh how phrasing it like that would irritate him) then of course everyone else would see his behavior as a temper tantrum and not a concern. He's just mad daddy doesn't love him, give it a rest. Yuri will get over this soon enough, he's a grown adult... right?

This would also mean that Yuri didn't need to ever have been placed in Frostheim. He always could have been in Mortranken, he just associated with Frostheim because he is the younger brother of the King. And why he hates Darkwick General so much and is so insistent on doing his own thing: he wants to prove he is more than his family name. That he can cure people, that he isn't his father's puppet. This would probably further drive the wedge between him and Jin, that's something Jin wants to do himself but can't on account of being the oldest son. He sees his little brother as privileged in the same way his little brother thinks he is.

Counter Arguments/Rebuttals:

They do not look much alike. Zenji and Jiro + Hyde and Sho do, so the game making them look different is my biggest reason I think this could be wrong. They don't need to be related for their dislike for each other to make sense, it would just be deeply tragic. And could potentially set up an arc where Zenji chews Jin out for being a shitty older brother, he loves Jiro so much he would die (and probably did) defending him. Why is Jin ignoring his brother? Has he no heart? (not to mention why Yuri is so attached to Jiro, little brothers need to stick together)

Different last names. I think this could be explained by Yuri using his mother's maiden name to separate himself from his family, which would further irritate Jin because how fucking dare he use their mom's name like that?

Like I said, this doesn't need to be the explanation for why Yuri and Jin hate each other. He very easily could have just been a student there and failed to help Jin through his injury. It makes just as much if not more sense. My one real reason for holding onto brother theory when that one works is that... fuck that's a lot of students transferring out of Frostheim. Almost too many to make sense if you go with Haku having originally been there too. It almost feels like it makes more sense if Yuri has always been in Mortranken... but not by much when you take into account everything else you need to believe in order for brother theory to be true.
