I had to look back at the previous chapters to find out the stats of the hero (chapter 34 page 9) and the dragon (chapter 41 page 8 initial stats of the new form, page 18, then chapter 42 page 1 before facing the queen - I'm not sure why but the level stayed the same at 41 while the attack just jumped between chapters - by the end of the fight, page 19 it had leveled up to 57, so even stronger), and indeed the dragon completely crushes the hero in terms of stats. The hero is basically a dead man at this point, unless he somehow finds a way to negotiate his way out, and I can't imagine that happening because he's too dangerous of an existence since he's also linked to "god's voice". I do wonder about the hero's attack and defence stats; I guess it's raw power and then the added damage from being equipped well. The hero might still have some dangerous skills but honestly it's hard to figure out just from the names.
The fight will probably still be difficult because our dragon is going to restrain itself in order to avoid harming the civilians. There is a second head that might have less qualms about the lives of the civilians though so I'm not sure the hero will be outright able to take hostages.
I wonder how cat-girl is doing - she was purified by the hero after all, so if she survives this, she may well live a life with a normal life span. I wonder if she'd stay with them. I think he's no longer emitting the poisonous stuff, right?
Man, it's hard talking about this when our dragon and the hero have the same name. -_-
