Iron Maiden

'''

An torture device invented by Lily through transforming a villager, the Iron Maiden catches men and locks them in, squeezing their semen dry with its tentacles. It is a lewd monster, for once captured there is no escape.

As Luka traverses through Lily's mansion, he meets a "Hero" battling an Iron Maiden. Luka tries to help, but the cages between them continuously deflect his attacks. The man is then sucked into the Maiden's interior and squeezed endlessly. A second Iron Maiden proceeds to attack Luka, but he holds his own and defeats it. Turning back to the first Maiden, her smile becomes more lewd as more semen drips. Angered, Luka marches into the mastermind's room once and for all.

Encyclopedia Entry
"The result of another of Lily's experiments in transforming a villager into a torture device, it locks a man inside it's body and uses every aspect of her interior to stimulate the man. Filled with tentacles inside of her body as he's left unable to move.

''Once locked inside, the amount of force needed to open her back up is greater than the power of twenty men. If caught inside, there is no escape. The Iron Maiden will force the man to orgasm repeatedly until their death. Lily uses the device to both collect a large amount of semen quickly and to dispose of men that have lost their use.''

''The Iron Maiden takes considerable magic to create, so only a few exist inside Lily's mansion. It's also believed that one escaped her dungeon into the wild."''

Battle Overview
The battle is more of a test of patience due to her high HP and tendency to open up and enter her Invitation to a Nightmare stance which will reverse any attack into a one-hit KO.

She lacks any form of direct attack to harm Luka but she has the ability to confuse him with Eyes of Confusion, meaning that he may inadvertently attack her while she is able to counter attack and losing the battle, babble incoherently, or attacking himself. Sylph is critical to avoid the status effect, however it is not by a 100% rate.

Should Luka attack and receive a counter attack she will shut him inside her before whittling down his remaining HP with a non-stop barrage of Nightmare Embrace from which escape is impossible. After which she will torture the Fake Hero with pleasure until death.

Attacks

Trivia

 * Nightmare Embrace has it’s own screen and has the H Scene music during the instant follow-up part of the attack, in gameplay the internal scene leads up to the first ejaculation before the losing scene. However, when the scene is recalled the internal scene is not seen at all until the second ejaculation.
 * Despite being a counter attack, Nightmare Embrace does not need to be triggered by an attack when requested, however the only way to request is by selecting the only option, Invitation To A Nightmare, as the former attack follows from it.
 * The oozing pose of the Iron Maiden is not seen in battle or scenes, but is seen on the epilogue losing screen.
