Headcanon No. 5

The Kyushu People are in reality a familiy.

Yoshihiro is the mother - always there to scold the kids if they do wrong.

Muneshige is the father - one of those nice and kinda weak-for-the-wishes-of-their-kids/daughter fathers who will do as told.

Kanbei the oldest son - always gets into trouble and feels unloved.

Sorin younger daughter - and quite annoying “Dad! Your voice is irritating me! I want a pony!”

Sorin is a manic fangirl about Xavi, a popular Band. Everywhere in her room you’ll find Poster of Xavi. On a regular base she makes Muneshige buy her all the merchendise. She’s also the president of the official “Xavi Fan Club”.

Mom is having an alcoholic problem, Dad only cares for the little sister and the sister is annoying. This leaves young kanbei to the evil Nanny: Yoshitsugu

Yoshitsugu is also caring for the annoying neighbour kids, Motonari and Mitsunari.
(Motonari is also the best friend of Sorin?)

They mock Kanbei, telling him that he’s only a dog and for that reason gave him a collar. They also make him do a lot of work.

When the bullying gets too much and Kanbei gets the impression that his genius is not appreciated enough he will flee to Grandfather Ujimasa, who lives with Cousin Kotaro in Odawara Castle.

Ujimasa is always happy when Kanbei is visiting him. They get along pretty well and together noone can stop them! Kotaro is not saying much to this, though.
