His form didn't look exactly human so the first thought the guards would have upon seeing him wouldn't be to rationalise with a fellow intelligent being, but instead thinking that they had to exterminate a crazy monster!
This originally wouldn't be that much of an issue. all Dante had to do was deactivate his dragonification form and everything would be fine
But here was where another problem came in.
When Dante deactivated his dragonified form he was left standing completley butt naked!
Earlier , Dante had absent-mindedly walked into a lava pool and in doing so caused all his clothes to be burnt to ashes.
but even with all this the problem, the real problem was that Dante had been forced to Chuck his space ring out the lava last minute and he had caused quite the disturbance when he first used his greater Dragonification so he couldn't find his spacial Ring!
After a few minutes of unfruitful searching Dante began to sweat.
