Laplace

Laplace an intelligent chimera, perhaps one of the strongest next to the Next Dolls, in Chapter 3. Fully composed by mechanical parts, she is one of the Seekers of Truth and serves as one of Promestein’s right-hands. Laplace monitors the Drain Lab. Not only is she is a semen extractor, Laplace was given extremely high intelligence with human thoughts and a "logical" thought process, but questions her own existence after feeling many "illogical" things.

Translated by Kusojijii:

Laplace

''The android that’s independently controlling the Drain Laboratory. A fully autonomous mechanical life-form that Promestein developed, her body makes no use of biological organs whatsoever.  Possessing superior independent will and extremely high semen-squeezing capabilities, her additional warfare capabilities also let her surpass even the highest-grade monsters of the Earth. ''

Battle Overview
Keep Gnome up at all times. She's 100% machine so Undine nor Sylph will be effective. When she prepares her Lo-li skill, keep enough SP around for a Daystar. Then continue to attack her normally.

If Luka loses, he'll be kept as her personal Guinea pig for the rest of his life.
