Xannaner, Demon Lord Of Pride

Xannaner, a powerful demon lord who prides himself with his luxurious life. A ruler over his own demon kingdom. Slayer of many dragons and kings. This demon is the older and most powerful among the demon lords. He controls the deadly sin of Pride, meaning he can easily make people so prideful, that it leads to their own downfall. Wielding a sword made from a dragon he killed a long time ago, it can inject dragon venom into the victim that's been stabbed or even cut. Depending on how well the victim can resist, they'll either day within seconds, or in 24 hours. Either way, they'll die in pain.
