Welcome to The World of Monster Girl Encyclopedia!
At present, due to the influence of the current mamono lord, a succubus possessing tremendous power, all of the monsters have forms like that of either an extremely beautiful, or cute human woman. Their forms are highly varied, running the gamut from being hardly any different from human, to only having the upper body of a woman, with the lower body of a serpent, fish, spider, etc., features of a beautiful, alluring human woman mixed with grotesque traits. Presently, as is visibly apparent, all individuals are female; a male has never been observed. Most of the monsters are more instinctual compared with humans. Their thoughts and actions are all based on desire and dedicated to the pursuit of pleasure. Compared with humans, many of them have greater physical or magical capabilities. They have various special abilities that humans do not possess. Intelligence varies greatly depending on race, but all of the monsters are at least smart enough to have a command of language. It is possible for them to converse with humans. They have long life spans compared with humans. (It varies depending on race, from only a little longer than humans, to those who live for thousands of years.) No matter how old they get, their forms remain young and beautiful, and they never physically age any further than that.
