idk if you'll see this or if it actually works but here's how a did it: Interact with the maids using ryia's list, just do all of them from left to right, after a certain one for some reason hellhound appeared in a maid outfit? I'm not sure why this happened but I guess the game expects you to have interacted with the maids before hellhound gets a uniform. If this helps at all then your welcome, which hopefully it will :)
