Luca

"I gave you an order! I asked for a protection fee, too! And you're gonna ignore the both of them?! You're really giving Leaky Eye Luca a "no" on both counts?! (おれはおめーに命令したんだ！　ショバ代を払えとも言った！　両方とも逆らうっつーんだな!?　この「涙目のルカ」に「両方」とも「」つぅーんだなッ！)"

- Luca to Giorno Giovanna

Luca (ルカ), commonly known by his nickname "Leaky Eye Luca" (涙目のルカ), is a tertiary antagonist featured in the fifth part of JoJo's Bizarre Adventure, Vento Aureo.

Luca is a Passione member controlling all illegal businesses done at Naples' airport. After finding out that Giorno Giovanna has committed crimes on his territory without paying his tithe to him, Luca confronts the young boy. This incident triggers the events of Vento Aureo, as Passione sends Bruno Bucciarati to find and execute whoever attacked Luca.

He has no known Stand but uses a shovel as a weapon instead, which he uses to beat people with.

Appearance
Luca is a man of average to below-average height, being nearly eye to eye with Giorno, with a hunched stature. The two distinct features of Luca's appearance are his constantly leaking right eye, which he received due to a previous facial injury, with the scar noticeable under his eye, and his bangs which come down into two points.

Luca wears a coat with flower patterns covering it, which are given more detail in the manga, over a button-up shirt. Luca is always seen carrying a shovel with the acronym "S.P.Q.R." engraved on it.

Personality
"I'm the one doing the talking here! Who gave you the right to ask questions, dumbass?! (話を今してんのは このオレだッ！　誰が質問していいと言ったッ!?　このボケがッ！)"

- Luca to Giorno

Luca is a ruthless and merciless gangster. Luca usually hides behind a masquerade of amiability and citing friendship as one of the most important values. However, he uses the term friendship to disguise his will to be obeyed and paid for what he sees as his due payments for operating on his territory. Luca is particularly callous and violent, threatening Giorno Giovanna for money, and refusing to listen when Giorno adamantly claims to have none. When he saw a frog, he also ordered Giorno to kill it and attempted to bash it, as well as Giorno. Narancia Ghirga comments that Luca was generally mean to others and that he sold drugs to children.

History
Nothing is known of Luca's past, except for the fact that he was in a fight that left him with his signature injury and moniker.

In the anime, Luca is first seen assaulting an unlicensed taxi driver who attempted to earn money on Luca's territory without paying him a protection fee. The man eventually rats out someone else who has been dealing behind Luca's back. After getting a name, Giorno Giovanna, out of the man, Luca thanks him for the information before finishing him off.

Luca meets Giorno at a fenced-off area of the airport and begins the conversation by asking Giorno his age, which he finds comical upon hearing. Luca then details the three pillars of friendship: truth, forgiveness, and above all respect. When Giorno dares to ask Luca what he wants, he immediately shoves his shovel handle in the youth's face and loudly rebukes him. Luca then reveals that he seeks a protection fee from Giorno, and begins searching his wallet. However, all Luca finds is a picture of Giorno's father, as Giorno had already paid a pair of guards to ignore his illegal activity.

Finding Giorno's wallet empty and becoming increasingly frustrated with the youth, Luca swipes at his neck with a shovel, though Giorno dodges the blow. Suddenly, a frog jumps out of a sewer drain and hops onto Giorno's leg, continuing up his body. Luca tells Giorno to get rid of the frog, but Giorno refuses. This second act of defiance drives Luca over the edge, compelling him to strike both the frog and Giorno's chest with his shovel. However, the frog fully reflects the attack back toward Luca, creating an imprint of his own shovel on the back of his head and killing him.

Following the incident, Polpo assigns Bruno Bucciarati and his team the task of investigating Luca's murder, despite Narancia's objections. Though Bucciarati initially assigns Fugo to the case, believing it to be of little importance, he decides to take on the task himself after he and Mista are attacked by a strange enemy Stand. While interrogating Giorno, Bucciarati initially states that Luca is alive, but in critical condition with little-to-no possibility of recovery. However, this is soon revealed to be a lie, as Bucciarati claims that his boss had Luca killed and allowed Bucciarati to use Luca's fingers and eyeball as scare tactics. Ultimately, Bucciarati reports to Polpo that he failed to identify Luca's killer, at the same time recommending Giorno to the organization.
