Who is Karoio?  
The English version was basically an unedited and un-proof read draft and contains a lot of mistakes, including some names who have been changed but I forget to follow up with subsequent chapters.

As for Hitomi, sorry, that is all left to your imagination.  She is very pretty of course, being the Yamabuki of Satomi.  
Aniue is not a person, it is a form of address that younger brothers and sisters address their elder brother.  Katsuo is tall and strong like a real samurai.
