Luca Stolas

As a notorious scientist, Luca is prideful of their intellect, but secretive of their actions as to not attract the attention of any Den mercenaries. They like to mess with others and ridicule them with backhanded statements for fun. They often say things to provoke. Luca's knowledge of things is often dubious, wherein they claim that ghosts are real or that they have the ability to determine when someone will die. Apparently, saying such things have gotten them in trouble many times before, as stated by their Conjurer, Patch.

Throughout the game, it's revealed that Luca feels a great amount of guilt for things they have done, including conspiring with Klein and the Queen, and the multiple failed experiments that lead to the death of other Mogwai. They consider themself vermin for becoming an accessory to regicide for the sake of an easy way into castle life. Luca tends to hide their many regrets in self-deprecating or black humor.

Typical for Yin Gyochu, Luca has a very short stature, though this does not bother them. They have messy teal hair, styled in low, lazy pigtails. They have a prominent cowlick at the top of their head which seems to split whenever they get excited. They wear a pair of glasses that obscure her eyes. Their white, purple-trimmed lab coat is too large for someone of their size, giving them loose sleeves which they seem to have adapted to. Underneath, they wear a white shirt with a purple trim. Around their neck is a strange necklace with a pendant that looks like a mutated, two-pronged, purple magatama. They wear black stockings under a teal skirt. Their footwear of choice are purple house slippers.

In their Mogwai form, Luca's "skin" is lime green and they have wide eyes that resemble their glasses in their human form. They have teal antennae stemming from the middle of their face. In this form, they have six arms with gloves for each hand. They have a purple carapace that protects their backside. They have a tendency to drool venom more while in this form.
