This chapter is the fight with Illuso, which was honestly difficult to make scene breaks for due to all the going back and forth between the mirror and reality. I hope I did a good job.

"What's a mirror even doing here in the first place?," Giorno asked, "It's a rather odd placement for it." Fugo then saw the figure manifest a humanoid being with a purple suit and goggled mask. The Stand made to attack Giorno and Abbacchio, causing Fugo to push them out the way. At once they seemed to disappear, to Fugo's confusion. He looked around, but the street was completely empty. Even the mirror was now empty. He looked around and saw a trashcan that had the writing reversed.

"What on earth is going on here?," he asked. "You're in my world now," a male voice said. Fugo whirled around and saw the Stand from earlier, which punched him right into trashcan. The man got out a clipboard. "I should introduce myself. My allies call me Illuso of the Mirror. My Stand is Man in the Mirror. I'm an information gatherer of sorts, necessary for a group of assassins. I've spent some time studying your members. For example." He unfolded a page from the clipboard and began to read.

"Pannacotta Fugo, age sixteen, born to a wealthy family in Napoli. IQ 152, accepted into university at the young age of thirteen. But due to a violent disposition, you frequently clashed with your peers and never got along with your professors. This culminated in you beating the living daylights out of one them with a four-kilo encyclopedia." Fugo spit out some blood. "The bastard made fun of my emotions over my grandmama's death." Illuso raised an eyebrow and looked through the paper. "Huh... I seem to have missed that detail. In any event, your life went into free-fall from there until you became a lackey of Buccellati."

"You missed another detail," Fugo said as he got up, "Buccellati's the one who helped me get my life together. I'm his partner, not his lackey." "Ah, forgive me," Illuso said, "I nearly forgot your group is known for its camaraderie. Anyway, where was I...? Ah yes, the ones following you are Leone Abbacchio and..." He squinted at the paper. "Come to think of it, I haven't been able to get much information on your two new members, Giorno Giovanna and Rarita Zeppeli. But Giorno is the other one following you."

"Just what did you do to them!?," Fugo called out. "To them?," Illuso said, "You seem to be under a misconception. I have done nothing to them... My only target right now is you." Fugo was pointing as he realized the numbers on his watch were reversed like the trashcan. "This is..." "Ah, you seem to be gaining some understanding," Illuso said, "You see, Man in the Mirror creates a mirror world. I place it in a reflective surface, and the first person who looks into it gets drawn in. You were the first to see the mirror, so it only affected you. Abbacchio and Giorno are still on the outside."

Sure enough, after Abbacchio and Giorno got pushed aside, they noticed Fugo had vanished. "What just happened?," Giorno said, "Where did Fugo vanish too?" "He was here a second ago and disappeared," Abbacchio noted, "He said something about a figure he saw in the mirror. Maybe he was right about us being targeted again. And if that's the case, the enemy's Stand may have something to do with why Fugo disappeared."

"So," Illuso said, "Why would you three be out in Pompeii? I overheard that you were looking for something important. Something about the Dog Mosaic?" Fugo narrowed his eyes. "You'll be getting nothing out of me! Purple Haze!" He moved to summon his Stand, but gasped when nothing happened. "What's going on...? I thought I summoned it." Illuso seemed to breathe a sigh of relief. "I'd nearly forgotten the most important facet of my Stand." Fugo looked confused.

Abbacchio saw it first. "Giorno, back away right now!" Giorno saw the purple patchwork humanoid and hurried back. "What is that? It looks... Feral." "An appropriate word for it," Abbacchio said, "That's Fugo's Stand, Purple Haze. If it's appeared then he's in the area somewhere close by, and alive. Just don't get too close. Its power is to create a deadly virus that can affect everything, even Fugo himself, within a limited radius. It represents his inner anger made manifest, how he can snap against foe and friend alike." "But if it's here," Giorno said, "Where's Fugo?"

"Well, if you won't talk," Illuso said, "I'll just get rid of you and then question one of the others. Oh, if you're curious about why your Stand hasn't appeared, it's because in this world, the only living things that can exist are me and whatever I permit to enter. Even Stand energy can't enter unless I want it to. And a good thing too. Your Stand is infamous amongst Passion, though I don't yet know the reason. But it's obvious it's a dangerous one. Now... Man in the Mirror!" Man in the Mirror pummeled Fugo, sending him flying across the street. Illuso then saw a bird carcass fall at his feet.

"What's it doing?," Giorno asked as Purple Haze started to move. "It's trying to move," Abbacchio realized, "Wherever Fugo is, he doesn't know where Purple Haze is. But he's trying to control him here. Fugo only lets out his Stand sparingly. I honestly didn't think you'd see it so soon after joining us. He must have his back to the wall if he's actually summoning it now." Purple Haze thrashed around, punching at the walls. "Damn! It's attacking something! Quick Giorno, get back!" Giorno did so on instinct as he saw a nearby crow fall down dead. The bird's corpse seemed to liquefy, and more crows were being similarly affected.

"Is that the virus at work!?," Giorno asked, "It's more deadly than I thought!" "It can kill and dissolve a living thing in thirty seconds!," Abbacchio said, "I don't know where the enemy is keeping Fugo, but they lucked out separating him from his Stand..." He pointed to the bulbs on Purple Haze's hands, one of which was broken. "When those bulbs are broken the virus is released. It spreads through the air and if it hits something's lungs or gets into their skin... It's all over. Luckily it only has a range of five meters, and the virus is weak to light, even something as simple as a street lamp. This close to noon with no cloud cover, we're safe at this distance."

"I had no idea Fugo had this much rage inside him," Giorno said. "Neither did any of us save for Buccellati when we joined," Abbacchio admitted, "Until we saw it for the first time. It strikes like a bomb and departs like a storm. Even Stands can be infected, unless they are specifically designed to be inorganic, like Narancia's Aerosmith." Purple Haze started wiping some spit off its leg, only to see it had transferred to its arm. It got enraged as it tried to wipe the spit away. It then punched at the mirror.

"Fugo may still be trying to control his Stand," Giorno said, "He mentioned something about the mirror earlier." "We'll worry about that when we have the key," Abbacchio said, "Once we've secured it we'll come back for him." "You've gotten a lot softer in attitude," Giorno noted. Abbacchio sighed. "It's that damn girlfriend of yours. She chewed me out after the incident on the yacht. In anger I called her out on speaking against a superior, and she reminded me her only superior is Buccellati. I let slip a little about my past as a cop... And she told me this isn't the police force. I can't fall back on chain of command if I want people to listen here. I have to show respect to get respect." Giorno smiled, and they hurried off.

"These birds caught some sort of disease," Illuso noted. He then heard the mirror shatter. "So your Stand is still attacking in the real world. Well objects that get broken there may get affected here, but that means little. And no virus can enter this world either. This is the end for you!" But before Man in the Mirror could attack, Illuso heard the sound of footsteps as they ran in another direction. "Two sets of footsteps... Kicking up pebbles. They're running to the Dog Mosaic!"

'Giorno and Abbacchio,' Fugo realized, 'They must have seen Purple Haze and decided to continue the mission and escape its range. Knowing Abbacchio he'll be coming back once the mission is over, but he doesn't know about Illuso's power yet.' "So your friends abandon you to complete the mission," Illuso said, "But that only confirms my suspicion. You came here to find something, perhaps something to help protect the bosses daughter." He ran off in the direction of the footsteps.

"Here it is," Giorno said as they reached the Dog Mosaic, "Now, where's the key we're looking for?" Abbacchio saw something glinting in the sun. "Right inside the cracks of the mosaic it seems." He reached down and pointed out an ornate key with a ruby in the handle. "Rather ornate for a vehicle key," Abbacchio noted. "Maybe it's not for a vehicle," Giorno suggested, "It could be for a secret safe house." Abbacchio then saw a mirror shard, Illuso inside it.

"A key you say?," Illuso said, "So I'll just take that key then!" He summoned Man in the Mirror. Quickly Giorno knocked the mirror aside and caused it to shatter. "You saw something inside, didn't you?" "Our enemy it seems," Abbacchio said, "Giorno, grab the key. I can handle him." "I wouldn't say that," Illuso said, "Since you shattered my mirror, I can now grab you from any angle." Abbacchio seemed to disappear into the mirror. Illuso grinned when Abbacchio appeared in the mirror world. "I'll only permit you to enter. Just Giorno left." "You won't get that far," Abbacchio said, and grabbed Man in the Mirror's throat.

"But... But how...?," Illuso said as he chocked, "Only a Stand can touch a Stand." "And so one has," Abbacchio said as his form turned into Moody Blues, "Giorno breaking the mirror had nothing to do with stopping you from grabbing me, but narrowing your vision so you didn't realize it was my Stand that you pulled inside your mirror world instead of me. He figured out how your Stand works back where you grabbed Fugo." Man in the Mirror was forced to the ground. "Moody Blues isn't very strong," Abbacchio admitted, "But from the looks of it, it doesn't matter since your Stand's durability is lacking."

Illuso chuckled. "Maybe so... But I still have the upper hand." He grabbed a nearby mirror piece and pulled part of Abbacchio through, causing part of Moody Blues to return. "Now you're immobilized!" Abbacchio chuckled. "Have you forgotten something? While you're here trying to kill me... Where's the key you're trying to obtain?" Illuso quickly ran after Giorno, only to find that he was right around the corner. Illuso laughed. "He's not even trying to run!"

He took a mirror shard, which was floating in the real world, and Giorno looked at it. "Now I have all three of you!," Illuso said as Man in the Mirror grabbed Giorno's arm and pulled him into the mirror world. But he gasped in horror as he saw Giorno's arm was covered in the same blistering sores that the birds earlier had, and there was a capsule on his finger. "Are you surprised?," Giorno said, "I ran after Purple Haze once I had the key. Abbacchio said we could go back for him once we had it... So I did."

"You idiot!," Illuso said, "Now you're infected too!" He freaked out as he also started to become infected. Illuso quickly tried jumping back into the outside world, but saw his arm come apart. Acting quickly, he cut off that part of his arm. "Giorno...," Fugo said, "Why did you...?" "Rarity told me about Abbacchio's past," Giorno said, "How he used to be a cop, and a good, honest one. Then one day he accepted a bribe from a pimp who was in trouble, but that same pimp later committed an armed robbery. During the struggle Abbacchio's partner got killed."

"Yes, I know all this," Fugo said, "That's why Abbacchio only feels complete when he follows orders, even if it means having to give up his own life or risk his friends." "But Rarity told him a gang can't run like that," Giorno explained, "Or it starts to fall apart." He grinned as a nearby brick started to move. Fugo looked confused. "That brick was transformed into a snake by Gold Experience," Giorno said, "But only on the outside world. Snakes can sense human body heat and use that to locate them."

Fugo grinned. "I can see why you call it Gold Experience. I'd all but given up hope... But you just gave us a golden opportunity. Purple Haze!" Outside, Illuso was sure of his victory, until he saw the brick-turned-snake and Gold Experience. His eyes widened when Purple Haze grabbed him by the throat. "No... I'd just gotten away... How did this happen...?" He then saw a mirror shard, and saw he could still get away. "Man in the Mirror!" Man in the Mirror managed to stop the punch, letting Illuso breath a sigh of relief.

It was short lived, as the capsules on Purple Haze shot off, impacting on the wall. Illuso gasped in horror as they started cracking open, releasing a violet mist. 'No... No... After that work... After all I did... I thought I had won... Please... Anything but this death...' Purple Haze screeched as it started pummeling Illuso, popping his dissolving head like a rotten melon as he died dissolving into nothing. Giorno, Fugo, and Abbacchio popped back into the real world shortly after.

"One last detail," Giorno said as he approached the snake, "I'm still infected after all." Fugo noticed the snake was still alive. "Of course! It may emulate a living thing because of the life energy inside it, but it's still a brick!" "And it was created when I broke the capsule earlier," Giorno noted, "And with it's help..." Gold Experience drew some of the snake's blood and infused it into Giorno. The effect created a vaccine, though the experience was painful. All the same, it worked, and the infection receded.

Fugo was gobsmacked at the audacity. 'Giorno Giovanna... I don't what it is about you, but you're willing to go to some extreme lengths for that golden dream Buccellati has so much faith in.' Abbacchio chuckled. "He's a complete idiot, and his plans are stupid. But they work out anyway. I guess if it's stupid and it works, then it's not stupid after all. Anyway, we have the key now, and some time to relax. I'm willing to bet Illuso expected to get the key here and never told his allies about us. Let's hurry back to Buccellati."
