Mantis

Encyclopedia Entry:
An insect type monster distinguished by the huge scythes equipped on both of its arms. They dwell deep in the forest, using the scythes on their arms to quickly bring down wild animals, etc. and eat them. Because of their appearance, they are also called “assassins of the forest,” and feared.

It’s very rare for a monster, but should they encounter a human man, not only will they not attack, they won’t indicate any interest whatsoever. In fact, they couldn’t care less. Their expression is always fixed, and they don’t feel anything like emotion. Nothing can stir their hearts. They live every day “just to survive.”   For that reason, they don’t take any interest in anything that isn’t necessary for survival. Since they can’t even eat a human man, to them, they are completely worthless.

However, since they are indeed monsters, they do need human men, but only during mating season. During mating season, they try to attack and seize human men, but no matter what, they only view them as a tool for reproduction. When they seize a human man, they skillfully shred only the man’s clothing to pieces with the two scythes on their arms, and go about initiating intercourse with indifference. It’s said that during this time, even right before they’re about to receive a man’s penis inside their body, they don’t indicate any emotion whatsoever.

However, from the moment they feel it inside, everything about them changes. After they’ve had sex with a man, they are mesmerized by the pleasure they tasted, and are overcome with joy and happiness, as though their emotionless state until then had been a lie. At that moment, for the first time, they realize how good it feels to have sex with human men, and just how endearing men are to them. In this way, after they’ve had sex with a human man even once, they totally become prisoners of sex with human men, awakening to their true nature as monsters seeking sex and pleasure.

After that, they don’t just live to survive. They start to live for the sake of living together with their man and having sex. Once they know the taste of a man, they’ll never let him go after their first time having sex. Their scythes will end up being used to protect their man, and hunt for him. And then, as though their former self was a lie, they’ll have sex with their man every night and enjoy the pleasure like a monster. Afterwards, they go back to their emotionless state just like before, but they do blush faintly when around their husbands, and you can likely see their lips forming into a smile just barely.
