Arlo, Adalwolfa's brother and the inugami Foxfire.
Foxfire is not normally so boldly colored he's actually transparent, but with a solid white background I decided to show his proper colors. here's how he looks when he's drawn properly: https://www.weasyl.com/~kibathedemonicwolf/submissions/1317674/family-fishing-day

not much can be said about these two at this time I'd like to keep most of there info under wraps at this time so it's more of a surprise later in the Sen comic.
