Demons are terrifying creatures. They're known for corrupting human souls, tempting them with false promises and outright manipulation, but that's not all they can do – some strange demons are also downright weird. There are enough references to demons, both as corrupters and possessors, in religions around the world that some of them are bound to be a little kooky.
That they have strange tactics for demonic soul corruption makes them no less frightening, however – the weirdest demons are still demons, after all. And, though their methods might be unusual, it's probably still best to stay away from them lest you see your soul corrupted, not because you've been manipulated, but because you've been lulled into a false sense of security. Just like their nightmarish demon brethren, it's probably best to laugh at this batch of strange demons from afar.
