The next morning, Jotaro woke up feeling refreshed, his body reinvigorated after a good night's sleep. Stretching his muscles, he let out a deep sigh before heading to the bathroom.
'I should buy myself a spare change of clothes when I go outside' He promised himself, seeing how he only had Jotaro's original clothes. Then he went to take a shower.
After returning to the bedroom, Jotaro summoned Star Platinum.
The familiar purple figure materialized in front of him, its purple face mirroring his own expression.
"It's about time I start experimenting,"
Star Platinum, his Stand, originated from the world of JoJo, a universe quite different from the one he was in now, Jujutsu Ka1sen.
So this change raised several important questions in Jotaro's mind:
Can he use cursed energy, or maybe can his own stand use it?
Could sorcerers see his Stand or touch it, or was it only someone like Toji Fushiguro, with his Heavenly Restriction, who was able to sense it?
Was Star Platinum closer to a cursed technique or more like a shikigami?
Was his stand more or less powerful because of his soul being different to Jotaro's?
Countless questions filled Jotaro's mind, but he decided to start with the basics.
'What exactly is cursed energy?' he pondered, his mind rushing through the fragments of knowledge he could remember from his past life. Cursed energy, at its core, was derived from negative emotions like fear, hatred, and anger. Of these, anger resonated most with him. Even in his past life, he had struggled with his temper, he couldn't deny it and Jotaro himself is a man you did not want to piss of in the original series.
Anyway, Joatro could see curses, which by definition meant he could also sense cursed energy now. Recalling how curses were born from the leaked cursed energy of ordinary humans, he deduced that curses themselves were essentially dense concentrations of that energy.
Closing his eyes, Jotaro focused on the lingering sensation he remembered from the curse he had defeated the previous night. Raising his fist, he concentrated harder, channeling his thoughts into action.
To his surprise, a faint blue, aura shimmered around his clenched hand. The glow was subtle but unmistakably cursed energy.
Jotaro studied his glowing fist, then his gaze turned to his stand, Star Platinum, carefully comparing the two. His eyes widened slightly as he noticed the similarities—the energy surrounding his Stand felt almost identical to cursed energy, except the colors and also there was something much brighter about the felling his stand radiated compared to normal curse energy. Star Platinum's aura was much more alive, like an extension of his soul... no, it is part of his soul.
Anyway, the similar felling was to strong to be ignored 'So, as long as someone can sense cursed energy, maybe they can also see Star Platinum' he concluded, thinking that he should stop summoning his stand in public unless he wanted to be discovered by others
Then an idea came inside his mind and curiosity spurred him to test a theory. Focusing his cursed-energy-infused fist, he delivered a swift punch to Star Platinum's chest.
The impact landed squarely, and although his stand did not take any damage from such a weak attack, Jotaro immediately felt a sting on his own chest, still the pain was nothing special, if anything Jotaro could compare it to a flick of a finger but...
'Just like in the anime, any damage Star Platinum takes comes back to me.'
"Interesting," Jotaro muttered, rubbing the spot where he had hit himself. It had been a while since he had seen jojo, so he needed to confirm how much of the attack his stand could withstand before its user would take damage.
The Stand's durability was much greater compared to his normal human body so it would still serve as a a great shield blocking attacks for him.
There was also something he wanted to confirm: could other sorcerers hit his stand? In theory, Jotaro thought they could, but he still needed to test it later.
For now, Jotaro had to make a comparison. Star Platinum wasn't like a curse but seemed more akin to a cursed technique, maybe like a Shikigami and at the same time Jotaro knew that in the end his stand was a manifestation of his soul and will power.
The hours that followed were filled with experimentation. Jotaro tested techniques like Star Finger, which thankfully worked as expected, but his attempts to stop time met with failure.
'Maybe my stand needs more time... or' Jotaro remembered how Star Platinum could only stop time after seeing Dio do it first. 'What a pain'
He also tested the Stand's range, confirming a critical limitation. While Star Platinum maintained its incredible strength within a two-meter radius, its power diminished noticeably beyond that point. By the time it was ten meters away, the Stand's strength barely matched that of an ordinary human.
After Jotaro discovered the limitation of his stand, he decided to experiment with curse energy once again. He focused once more, this time attempting to channel cursed energy into Star Platinum directly. His goal was to enhance the Stand's power, much like how sorcerers use curse energy to enchant their body and weapons.
Minutes turned into an hour as he concentrated, beads of sweat forming on his brow. Yet despite his efforts, the two energies seemed incompatible, repelling each other like oil and water. His cursed energy reserves were nearly depleted by the time he gave up.
"Tch. Whatever," Jotaro muttered, dismissing his frustration with a wave of his hand. He wasn't one to dwell on failure. He was still a novice on this, barely able to manipulate cursed energy. Expecting to pull such a thing first day was was unrealistic, and he did not know if it was even possible.
One thing was certain tho, his body can use curse energy so at the very least he would have a stronger body, the main weakness of a stand user was his own body anyway so being able to enchant his body was a win in his book.
And so time passed, hours exploring his new world turned into days as Jotaro fell into a routine.
Each morning, he trained, experimenting with Star Platinum's capabilities and improving his control over cursed energy. Afternoons were spent gambling and using his stand to earn some fast cash.
He did not want to sleep on the streets like that bum, Jotaro clenched his fist in anger remembering how he was taxed by a homeless man.
