Josuke walks onto a bus and there he saw Rohan. 

Josuke: Oh ... uh ... Crap! It's Rohan! I sure ran into him at a bad time. 

Rohan: Why are you avoiding me? It's only polite to say hello. I am older than you after all, Josuke Higashikata. 

Josuke: Uh, sorry about yesterday. The fire was ... pretty ad, right? 

Rohan: Yeah. I had a complete replica set of Drexel Furniture used in the movie, "Prety Woman" valued at 2.5 million, which was damaged beyond repair. Not that I care or anything. 

Josuke was silent, he couldn't tell if Rohan was being serious or not. 

Rohan: What's wrong? Have a seat. It's the only empty one on the whole bus. 

Josuke: Uh, that's okay. I'm a young guy, so I'll just stand. 

Rohan: Are you implying that I'm old? You know, the bus company put these seats up so anybody could use them. Just sit down already. 

Without any hesitation, Josuke takes his seat in front of Rohan as the bus enters a tunnel. 

The mangaka was staring at him the whole time. 

Josuke: Gimme a break. He's staring at the back of my head enough to bore holes and it's so quiet in this tunnel. Man, I gotta switch busses quickly! 

Rohan: Someday Josuke Higashikata, someday I'll get you back for yesterday's game. 

But just as Rohan's thoughts were complete, he spotted something! A room in the tunnel! And there was a dead women's body in it! 

Rohan: WHAT IS IT?! JOSUKE! DIDN'T YOU SEE THAT?! THERE'S A DOOR IN THE SIDE OF THE TUNNEL! AND SOMEONE'S IN THERE! 

But Josuke was annoyed. 

Josuke: Is he trying to mess with me again? Give it a rest man! 

Then even worse, Rohan saw a man holding a knife next! 

Rohan: There's a man in there too?! I can't see their faces! What is he- 

The man cut off the woman's hand! 

Rohan: JOSUKE! LOOK! 

Josuke: GET OFF MY ASS ROHAN! IF YOU WANT A FIGHT, AT LEAST WAIT UNTIL WE GET OFF THE FUCKING BUS! 

Everyone else stared at Rohan as he calmed down. 

Rohan: I ... only saw it? That man ... he cut off the girls' hand. Can it be ... Kira? 

He then faced Josuke. 

Rohan: So, you don't believe me? 

Josuke: There's a house built into the side of the tunnel? You're obviously trying to get back at me by making up some outrageous story so I'll follow inside a dark tunnel and you seriously think I'll buy it?! Look the fire yesterday wasn't even my own fault! Let me off the hook! 

He goes to leave. 

Rohan: JOSUKE! THIS IS NOT ABOUT THE FIRE! I'M TELLING THE TRUTH! 

Josuke: If you hate me this much, then leave me alone! 

Rohan: Oh, this is rich. You're a liar and a cheater, so now you have the gall to accuse me of lying? 

Josuke: Are you going to get off or should I? 

Rohan: Ugh, fine. I got it. I'll handle this myself. 

Rohan gets off the bus and faces the Twin Forests Tunnel. 

Rohan: Hmm ... it's only 450 meters long, but because it curves, you can't see the other end. Was I hallucinating? No ... I definitely saw it. So what was it? I'm worried that it might be an enemy stand attack, if this room was created by a Stand, then the user might be leading me into a trap. 

He then sees a motorcycle nearby and gets on it. 

Rohan: It looks like a normal tunnel, though. It's got the same amount of traffic as usual. So it's safe to pass through. Okay, here I go. 

He speeds into the tunnel, with the single light showing the way ahead. 

The only sound aside from the motor was the water leaking from the ceiling. 

After a while, Rohan spotted an exit sign. 

Then he returned to where he saw the room, but there was no door. 

Rohan: Nothing. Just a wall. No door, or window. No openings of any kind. It's just a normal tunnel. Was I really just hallucinati- AH! 

Rohan fell inside the room as the door suddenly appeared and opened up. 

Rohan: THE ROOM! It revealed itself somehow! This is definitely the room I saw from the bus! But the man and woman from earlier aren't here. 

He heard a noise from nearby. 

Rohan: SHIT! 

He ran out of the room and back to the motorcycle. 

Rohan: I HAVE TO MOVE! THIS WAS A TRAP! 

He speeds off as fast as he can! 

Rohan: I'm glad I brought my bike. Something was following me. I couldn't see it, but I know it's after me. Whatever it was, it wasn't human. Probably only Stand Users like me can see that room, which means it's an attack! I guess that Kira-like guy was just an illusion. 

Then he saw something coming after him! FOOTPRINTS! 

Rohan: What? Is this the Stand? 

It was gaining on him! 

Rohan: THEY'RE KEEPING UP AT 60 KPH?! 

He increased his speed and outraced them. 

Rohan: Good. I lost them. It must be a remote-control type Stand. If it can run at 60 KPH, that's 100 meters in just 6 seconds. 

He reached the end of the tunnel and saw a truck coming his way. He avoids it, but then one of the footprints lands on his back! 

Rohan: DAMN IT! IT CAUGHT UP! I slowed down to get away from the truck, and that's all it took! 

Another one slams onto him. 

Rohan: HEAVEN'S DOOR! 

But then he felt himself getting weak! 

From outside the tunnel... 

You, Ruby, and Yang found Josuke. 

(Y/N): So, what's up? 

Josuke: I get the feeling that Rohan is in trouble. 

(Y/N): Goodbye. 

You were going to leave, but Ruby stopped you. 

Ruby: (Y/N)! We have to help him. He's our friend. 

(Y/N): He's your friend, Ruby! He's not my friend.

Yang: Yeah, I don't like him either. He's a total dick and- 

Rohan's motorcycle went flying out of the tunnel! 

(Y/N): WHAT THE HELL?! 

Josuke: Rohan's bike? 

Ruby: But where is he? 

Inside the tunnel... 

Rohan was on the ground as he saw the footprints coming together to form a Stand! 

???: Nourishment! Give me your energy! 

Rohan: HEAVEN'S DOOR! 

Rohan was able to extract information! 

Rohan: The Stand is Highway Star, and that room was a trap, anyone curious enough to enter gets chased down by scent and has their life force drained away! 

Highway Star: YOU CAN'T ESCAPE! 

Rohan: DANN IT! 

Rohan was losing his strength. 

(Y/N): ROHAN! 

Ruby: HANG ON! 

You all ran inside. 

Rohan: Is that ... (Y/N)? Ruby too? 

Highway Star: Allies. 

Josuke: Dman it, stoo dark in here. 

Yang: Where did he g- LOOK! 

Yang spotted the room. 

And over there was Rohan! 

(Y/N): ROHAN! HANG ON! 

You all ran to him, as Highway Star appeared. 

Highway Star: Hey Rohan, get them inside of here. If you let those four in here, I'll let you live. I'll take their lives instead. 

Ruby: What's going on Rohan? 

Josuke: Is someone in there? 

Highway Star: Say it! Get them in here! 

Rohan: Are you telling the truth? If I sacrifice them, you'll let me live? 

Highway Star: Scout's honor. Their energy in exchange for yours. 

Rohan: NO WAY IN HELL! 

Highway Star: WHAT?! 

Rohan: GET OUT OF HERE! IF YOU ALL ENTER THE ROOM, YOU'LL DIE! 

Highway Star: DAMN YOU! 

(Y/N): LIKE HELL WE'LL DIE! 

Josuke: We just need to beat the shit out of him! 

All four of you step in. 

Rohan: WHAT THE HELL DO YOU THINK YOU'RE DOING YOU IDIOTS?! NOW HE HAS YOUR SCENTS! 

Highway Star: THAT'S RIGHT! 

He turned into the footprints and went for all of you! 

Rohan: HEAVEN'S DOOR! 

Rohan wrote on all four of you, "I'll fly out of the tunnel at 70 KPH!"

And just like that, all of you flew out! 

Ruby: ROHAN WHAT ARE YOU DOING?! 

Yang: YOU IDIOT! YOU'LL DIE! 

Rohan: NEVERMIND ABOUT THAT! YOU HAVE TO TAKE OUT THE USER! HIGHWAY STAR WIL CHASE YOU AT A CONSTANT 60 KPH! 

You all went out of the tunnel where Rohan's destroyed bike was. 

(Y/N): He ... saved us. 

Yang: He actually ... saved us. 

Josuke: I thought about it. I was going to say I didn't want to see him again for as long as I lived. 

Ruby: I told you there was good in him. 

Josuke fixed Rohan's bike and Yang used Requip Magic to get her bike out. 

Yang: Let's find the fucker who did this to Rohan, AND FUCKING BEAT HIS FACE IN!
