Inuyasha, Rin

There was a whole family that had gone as Inuyasha characters. This may sound weird considering that this picture and the next are not only from that family but ae also from Inuyasha, but I think they had done Inuyasha in 2002. This year most of them were from Star Ocean EX. I know my sis got a pic of them which is why I know they were from 2003 (not to mention Rena is in the background of this picture), but the mom (the Kagura in the back) I thought was also a part of the SO EX group... So I'm a bit confused, but oh well.
