Xa' Tsu was originally going to be a siberian tiger but when I outlined Act II i decided that Tanjo wasn't going to be the standard Bengal so when I colored it I also adjusted the character a bit.
Xa is much like Inari in many ways. I'm wondering if I should decide to make anything bigger out of that but I'm not entirely sure I can write objectively like that what with... stuff thats happened >< don't ask unless you want a loooong explanation. Anyhow, regardless of their relation, they both end up saving the others' life on more than one occasion.
She like him is also a wanderer. However, she wanders to find help for her people. Her hometown is under constant danger from Avatar minions and when she learns what Inari is up to she joins in gladly.
