Bleach B.O.F. and Dark Souls

Why are there passwords that you have to draw? I've yet to figure this out. I mean I've found "Said" passwords for Blade Of Fate, but how do you go about drawing them. I've tried so many times with so many variations. I just can't figure it out. Maybe someone that reads this will be able to tell me.

 

I've actually got two passwords figured out for Dark Souls. You get heaps of cash. I'll post a few pictures later.

 

Here's a few from Gamefaqs.com

Those aren't them, just showing what they have unlocked by drawing.

How the heck would anyone guess that?! That's insane! How the heck do they think we would know you should draw a freaking dog man? That's seriously insane XD

 

That's what they are that dog thing and that girl? I printed our the dog one, and tried to copy it to the best of my ability. but I still get "that's the Wrong Password" from Urahara.
