CoolK: Some more great ideas, and don't worry, you'll get more.
Coco Jumbo: It's going to take a lot of coaxing from their friends for Johnny and Kyoka to finally say how they feel. Jotaro is vastly inexperienced, but his heart is in the right place.
I'm not sure if I want Susan, of all people, to be the catalyst that brings them together. She might play a part when she inevitably confronts them, but having them confess their feelings for each other after a life threatening experience probably isn't a good choice in their part. After, maybe...
I think Izuku would be mad, but not about Valentine, but rather because Johnny lied to him. Those two have been friends since they were little, and depending on how Johnny goes about it later, he could fracture Izuku's trust in him.
Then again, would all that drama really be necessary?
ThanoSstinks: Yeah, but they won't be teaming up. Santana believes that humans are beneath him, and Susan has gone full cuckoo mode. An alliance between the two would undoubtedly fail.
TheSBRdude: Izuku...what are we gonna do with him? And Susan is going to meet her end, I can assure you. Let's just say...she's already interacted with her killer in previous chapters.
Also, Gyro's room is open to interpretation. I know what it looks like, but it is ultimately up to the reader's imagination.
As for Santana's eventual stand...let's just say he'll be a kingpin of sorts going forward, because people WON'T want to mess with him.
Kosaku Valentine: I'm running out of ways to thank you!
...
"Kujo."
Johnny groaned. "Five more minutes..."
"Kujo, you need to listen to me."
Johnny's eyes shot open as he recognized the voice, and he came face to face with Funny Valentine. "Son of a-"
"Relax, this is inside your head, I'm not going to try and kill you."
"Bullshit. What the FUCK, are you doing in my head?!"
"I'm here to warn you."
"WARN me? You want me dead!"
"That is no longer my intention, you took the Corpse, you were victorious, and there is nothing I can do about it now. What I can do, is prepare you for something that could end society as we know it."
"What? Why the hell woul-"
"I don't have a choice, I'm dead. Beware, Johnny Kujo...the Demon rises..."
...
"WAIT!"
Johnny sat up in bed, breaking out in a cold sweat. His door was kicked open, and Gyro burst into the room with a frantic look on his face. "WHAT HAPPENED?!"
"I...I have no idea..."
Johnny proceeded to tell Gyro about his dream, and the Italian's face went from concerned, to angry, to confused.
"So...was it some freaky dream, or was Valentine giving you a message from behind the grave? And what did he mean by Demon?"
"I don't know..."
"If that was real, how the hell did he get into your head? You're not possessed or anything, are you?!"
"I don't know! It was freaky, that's al!."
Gyro pulled out his phone. "I'm letting Kyoka know about this...should I tell your dad?"
" Yeah, get them both...it could be nothing...but I can't shake the feeling that it wasn't..."
...
"So now the President's ghost is talking to you in your sleep, great." Kyoka remarked. "Why can't that maniac just leave you alone?"
Jotaro frowned. "He was giving you a warning...why? He spent a whole race trying to kill you."
"He said he didn't have a choice..."
Jotaro paced around the room, clearly deep in thought, before stopping. "We don't have enough evidence yet, so the only thing we can do is speculate. In the meantime, you three keep your guards up."
"Yes sir/Dad!"
...
*Author's Note: At this point, Susan's lost it. Jotaro's punch was the straw that broke the camel's back, and now she's practically foaming at the mouth. Her reputation was destroyed, the love of her life just bashed in her face, and her daughter doesn't love her anymore. Susan has literally lost everything, and in her irrational state of mind, she blames Johnny.*
...
Susan Cujoh began scratching down ideas into her to do list.
Johnny's friends, especially that flat-chested bitch, had beaten her on his orders, there was no denying it. Jotaro was under some sort of mind control, the real Jotaro loves her.
1. Get rid of Johnny's friends, especially the girl. Make him watch.
2. Johnny dies.
3. Jotaro and Jolyne love me again, live happily ever after.
Susan grinned, the plan was foolproof. All she had to do was kill Johnny, something she should have done a long time ago, and the spell over her family would be broken. Everything would return to normal, everyone would love her again...
Santana watched from the shadows in disbelief. Are humans really this quick to dive into the depths of insanity? She's mad!
But the crazy ones always do the most damage.
Santana crept up behind Susan while she was continuing her insane ramblings, and plunged the stand arrow into her neck. Susan's eyes nearly popped out of her head as she fell to the floor, gurgling.
Santana watched as the unhinged woman convulsed on the ground, waiting. Sure enough, Susan went still, and began to sit up...
And then Santana clobbered her across the head and yanked the arrow out of her neck. She survived the stabbing, which meant that the arrow works. He had no further use of her.
Santana could've left Susan's body where it was, the police would think it was a suicide, especially taking recent events into account. He had no problem leaving a human for dead.
Except he didn't.
With Susan making a splash, the Joestars would be too focused on her to worry about him, and he would rise.
...
Gyro threw a steel ball into Cementoss's wall, gritting his gold-plated teeth. The class was attempting to create special moves, and since he was a newbie, he had to work harder than everyone else.
Johnny was in the same boat, since he was absent from class for months. The two of them had a lot of catching up to do. Even though he arguably had more experience than his classmates, he had to play it off like he was out of practice in order to avoid suspicion.
"So, got any ideas for a special move yet?" Kyoka asked Johnny.
"Technically, my special move would be the Infinite Rotation, but it's kind of lethal, so..."
Kyoka knit her eyebrows together. "Well, what if you did something with your wormholes? Or maybe combine attacks?"
"Hmm..." Gyro scratched his patchy facial hair. Then he got an idea. He threw both of his steel balls on the ground, and Johnny and Kyoka watched in awe as Gyro stood on the spinning projectiles, riding them around like some kind of hoverboard.
"Well...Gyro just showed us up."
Kyoka smirked. "I don't know...I think mine is pretty cool, might just knock him off of his feet."
Johnny raised an eyebrow. "Don't you already have Soundwhip Barrage?"
"Two special moves are better than one."
"Well, what is it?"
Kyoka gave Johnny a coy look. "You're gonna have to wait till the Provisional License Exam, I'm not going to spoil anything."
"Fine, then I won't show you mine."
"You just said you didn't have one!"
"No I didn't."
Kyoka punched him in the arm.
"Ow..."
"Listen, you're one of the smartest people I know, I'm sure you can think of something."
"Yeah, but did you have to pu-"
Johnny suddenly had a devious grin. "I found it."
"You found it?"
"I know what my special move is."
Kyoka sighed. "Of course you do."
...
Santana winced and drew his foot back, but slowly put it forward, staring in awe as the sunlight touched his skin, and nothing happened.
The Pillar Man slowly stepped out into daylight, his expression one of childlike wonder. He had never been out in the sun before, save for his first battle with Joseph, and now he was doing something that Lord Kars had always dreamed of.
His new stand worked, he could finally see what he had been missing out on. Now that he had conquered the sun...
It was time to see how the Joestars fared against his stand, Genesis.
