Monsterpedia Entry
"A monster stone statue, located in the "Navel of the World". She was originally a spy keeping watch on the Gate during the Sacred Monster Wars. But after two thousand years she became bored and lost interest, and instead switched sides to guard the gate. As she was the second in command under the second Monster Lord, her power is equivalent to a current Queen class.

''In truth, she doesn't care about either side or the war going on. She's just looking for things to amuse and occupy her during her eternal vigil. If you fall victim to her, she will turn you into stone with her, and continue to toy with you for several thousand years."''

Attacks
Eye of Submission: Causes Luka to masturbate, only can be used in stone form. Dodge with Slyph

Gargoyle Blowjob: Normal attack.

Gargoyle Paizuri: Normal attack

Gargoyle Bosom: Binding attack. Takes three turns to turn Luka + Gargoyle Girl to stone. Requires Gnome to escape. If not escaped leads to OTK

Battle Overview
This is a hefty fight, first summon Gnome to break free of her grip when she captures Luka. Once you break free of her grip she will turn to stone, next summon Slyph to guard from her Eye of Submission or  Confusion, then Meditate and use normal attacks, save the SP for summon and meditating. When she reverts back to normal, repeat the process.

Evaluation
"She has been watching the gate for centuries. She must be quite bored. But now she has you as a toy to pass the time with. You're such a nice guy. The Gargoyle is a powerful enemy who charges up her attack patterns. In her normal state, Gnome is required to break free of her restraint. When she goes back into her statue form, summon Sylph to avoid her status effect inducing skills. When she is in her statue state, you can continue attacking her. Don't be worried about some sort of counter. Now go, oh brave Luka. End the endless shift of that Gate Guard."
