I agree with what's said above :P

Spoiler for nanjo:

For me, Nanjo has been suspicious right from the very beginning. The fact that he is Kinzo's long time friend, his silence at times, among other factors (as an amazing loophole in a certain part of episode 1) lead me to believe that, if he's not the mastermind, it' he's at the very least an accomplice, and possibly he is being blackmailed, for example.

But in the same all the stakes, goatheads, siestas and so on could time be mere objects, personified in the version presented from Beato to Battler.

I strongly believe this, for many reasons; obviously for their names (siesta's names are incredibly obvious as they are named after guns, stakes being real stakes), which also might explain why Beato (at least for episode 2), never attacks herself but summons this "furniture" (= weapons.).
