Is there like actual historical beef between the east and west of Japan??

https://en.wikipedia.org/wiki/Battle_of_Sekigahara a conflict between the Tokugawa faction in the east and the Toyotomi loyalists in the west. The north-south conflict they mention might be https://en.wikipedia.org/wiki/Nanboku-ch%C5%8D_period a conflict between the Northern and Southern Imperial Courts.
Its not a bad read I just think these kinds of stories are stupid?
They'll eventually have to explain it to his sister... wtf she gonna say?
Almost would have been better if she had died
Bro she abandoned him
With the expectation that he'd end up like their father dying all the same
There would be a hell of a lot of feelings resurfacing when facing them again
