Stop poking holes in my garbage
Just like with Illuso, I completely forgot Luca existed for the longest time. But, there are 2 options I have in mind to explain him.
1. I could argue that Luca just... doesn't count.
Like the nameless teen in the beginning of part 4, Luca wasn't really a character. Sure he's got a name, and apparently a Stand, but nothing else. And unlike with that nameless teen whose face Josuke reshaped, there wasn't even a fight on Giorno's part.
Giorno warned Luca not to hit the frog, Luca hit the frog, Luca basically died. He's a throwaway character with only a little more substance than mario the old man from the Black Sabbath fight, or the truck driver from the Kraft Work fight.
2. The name Luca comes from Lucas, which comes from latin 'lux', meaning 'light'.
If you have enough heat, it radiates light.
Campfires, stovetops, ovens, etc; most of what we use to cook things involves light for one reason or another.
About as farfetched as '[piatto] del giorno' ([dish] of the day), but neither's completely ungrounded and absurd, so I'm at peace with the ridiculous roundabout logic I'm using.
For anyone who doesn't look through notes (understandable), sandersfanders1 also pointed out that I forgot Illuso.
My original idea, which I didn't bother mentioning, was diluting; to weaken or thin out a substance, which is a process often used in cooking.
I thought it worked because the english meaning of illuso is deluded; but, clearly, I remembered the definition of the wrong word. If I hadn't run the idea by some friends, it probably would've taken days before I realized...
So I took almost an entire day to figure out something food-related that could be considered mirror-like, which... I ended with nothing except mirror cakes.
