It's been a while I've seen Inukami, but the old lady's name should indeed read Kawahira Kayano. For sure she's Keita's grandmother, other than Hake's "master".
Anyway, kudos for actually being aware of that series ^^ . It might be odd and different than usual, but I always thought of it as a kind of unappreciated work.
Do you take request. I want a sig like that out of images from Bleach of Ichigo or IchiRuki, UlquiHime or a black and white one of the guy I am wearing in my current sig. Or something like that. Would you be willing to do one when you have time (I am not rushing I can wait ...I just want a yes) If you can't...no hard feelings. If you can...I will glomp you a lot
