First I need to give credit where it is due and that is to YoukaiYume who is the wonderful artist of my profile pic. I love her fanbabies as she calls them.

Kei (eldest with black hair)

Kasumi (second eldest, girl with pigpigtails--which are her floppy dog ears btw)

Seishiri (youngest, silver haired kid)

She has more great fanart of Sess and Kag and a couple more of the 'pups' lol here: http://youkaiyume.deviantart.com/
