You remember Sulkakul [link]
? Here is Hukkaparka, another imaginary friend of mine as I call them.
While Sulkakul is the neutral or positive person, Hukkaparka is negative. I would also say she's my trash can of "useless bad feelings" like nervousness or anxiety, as I like to give them for her. She has some tough life. However, I never actually interact with her. Instead I make Sulkakul interact with her for me. Whatever I have to say for Hukkaparka, Sulkakul works as a messenger between us. She also takes care of Hukkaparka, if the canine-masked girl needs support.
About the name:
"Hukka" can mean wolf, although it literally means waste / loss / ruin, and "parka" means poor (like pitiful, not penniless), so her name is something like "Poor Wolf"
