Well... The appearance of Ajoora (the female protagonist) is practically the same as the classic monster girl hellhould. In my opinion what makes her truly unique is the story that characterizes her 😉
By the way, Burning Soul has a completely different lore than the Monster Girl Encyclopeida can have, but is correct give the proper credit for the original concept art (I did it in the credit section)
No other "famous" monster girl here XD
