Mantis Girl

Mantis Girl is a large mantis monster who has an appetite for men and other monsters, although in some cases she may use a man as a reproductive tool. Her physiology allows her to capture and mate with men pretty quickly, holding men in her bladed arms before using her flexible abdomen to take advantage of their prone position.

Like most insect monsters, her main drive is mating and she makes use of her mates not only as a source of semen to fertilize her eggs but also to nourish them after she covers his body in them. As she doesn't kill her mates afterwards, anyone unlucky enough to be given the position can only look forward to an endless cycle of being used as a reproductive tool with no escape.

Luka encounters Mantis Girl after stepping into the Gold Region. He finds Undine useless at this moment, creating a wall of water that reduces a tiny amount of damage, and falls back onto using Gnome and Sylph. Eventually, he overcomes the insect and seals her into a tiny mantis.

Encyclopedia Entry
"An insect monster strongly resembling a praying mantis. A carnivorous monster that eats not only other monsters, but human beings as well. Their favorite food however is male semen, and will both use them for reproduction and feeding. Due to their unique insect based vagina, any male caught by them will be enraptured in the unique sensations. After forcing her prey to multiple ejaculations and weakening them, they will then usually eat their mate.

''However when the mantis chooses a mate for reproductive purposes, she won't eat them. After she has been inseminated, she will lay her eggs on the male's body. The eggs will in turn stimulate the man, forcing him to multiple ejaculations, providing nourishment for the newborns. Like this, the male is used as a tool for reproduction all the way until their birth. Once captured, the male will be kept as a reproductive tool for the rest of his life."''

Battle Overview
On paper Mantis Girl does look like nothing out of the ordinary with two normal attacks and a bind attack, but in reality the battle pace is kicked up a little bit by her binding ability. Once she uses Embrace Luka only has one chance to escape before Mantis Rape comes into play and ends the battle quickly. The trick is to use the right summons as quickly as possible: Gnome is the key to break out of Embrace quickly so having her up from turn one is the preferable, seeing that her shallow attack pool gives her a fair chance of using binds quickly. Afterwards, she can be blown away with Death Sword Chaos Star.

Although Undine is mentioned in the dialogue, using her will just create more dialogue on how useless she is in the battle.

If she defeats Luka, she will grab him from behind and push her abdomen into him to fertilize her eggs before cocooning him in said eggs, effectively keeping him as a mate. The cycle continues ad infinitum.

Trivia

 * Female Praying Mantis are noted for devouring the male after mating, however Mantis Girl reverses this, only refusing to eat men if they mate with her.
