This chapter had some interesting information. This world seems to work a lot more on video game/MMO rules than it initially seemed, since even humans vanish after a time when killed.
Additionally, we learned something important. Which is that "Maou-sama" apparently has his own default personality, no different from the Dragonnewt/Martial Hero. When he's not being directly controlled, the Dragon acts in a completely corny, exaggerated, and over-the-top hero way. Apparently this same rule ALSO applies to 'Maou-sama.' When the main character is not directly controlling him, he also reverts to a 'default' overlord villain personality, or at least, that is what appears to be happening.
Also, Thrones seems to be involved in this somehow, since we know for a fact Thrones put himself into the ring (the translation back then was a little vague, but that is what happened). In fact, Thrones seems to be the one who reverted Maou-sama back to MC control.
We also learned something else that's very important. Maou-sama and the Dragon have various powers, abilities, resistances, and tricks, most of which we assume the MC gave them when he created them in the original MMO. But he himself seems to have no resistance to magic whatsoever. And that seems to apply ONLY to 'him,' the disembodied him that controls the avatars. The basic bitch sleep spell absolutely, 100% worked, but only on him. Maou-sama shrugged it off and then slaughtered both of those nerds before the ring did something and (we assume) Thrones handed the MC back control. That's a really, really dangerous and important weakness for him. If he can't find a way to block magical and psychic attacks, even some cutpurse on the street could easily take him out, and then accidentally cause a catastrophe when whatever body he's in goes on autopilot.
