The Multiversal Tourist 5 (Patreon)

This was the first time he was seeing a "Zero" since birth.

Actually ... No. He had seen something similar once previously.

He remembered talking a walk with his mother when there was a man standing behind them. The man was just as strange as this one, possessing no cursed energy whatsoever.

"Haruto?" Hana glanced at him, mid-sentence with Mrs. Tanaka. "What's wrong?"

"Nothing. I just saw a blue bird." Haruto replied before moving forward, paying the interesting young man no further attention. In the distance, Satoru Gojo watched as the young man left with his family, brows slightly furrowed.

Just as he was considering what to do, he felt something.

On the rooftop, a cursed user with a sniper rifle felt his hairs stand on end as Satoru Gojo's indifferent gaze landed on him.

In a cafe just across, a second cursed user, an old lady had a similar chill run down her spine. Both hid as quickly as they could, their original plan of ambushing the kid for a bounty being forfeited.

Seeing this, Gojo looked back, only to see the family was gone.

His brows furrowed even deeper before turning and heading on his way. As for the cursed users who were supposed to make an attempt on his life?

"Quit looking at me weaklings."

Suburban Tokyo - Late Afternoon

Haruto and Mio reached the play area while their mothers settled onto a nearby bench, their voices drifting away into a comfortable, background drone of neighborhood politics.

The park was typical for suburban Tokyo—neatly trimmed grass, a sandpit, a set of swings, and a slide that had seen better days.

Mio immediately gravitated toward the swings, her earlier shyness evaporating as she claimed one and began pumping her legs. Haruto watched her for a moment, then moved further away to a more secluded area and settled beside a stump. 

He opened his note to a particular page. There written on it was a bucket list, filled with different boxes.

Achieve successful biological incarnation ✓

Perfecting the reversal of Cursed energy ✓

He had been as thorough as he believed he could be. For nine years, he had played the role of the perfect son, the quiet student, and the observant neighbor. He had savored the texture of rain and the bitterness of tea.

Snuck out and travelled to other cities in Japan, been to the ocean, observed the vast majority of species on this planet, found five new ones and three supposedly extinct.

Mastered his cursed energy transmutation and manipulation, created his own documentation of cursed techniques he had come across, and been to outer space.

If not for the distance being too great and the uncertainty of life and resources on the other side, perhaps he would be thinking of travelling the universe by now.

'The Jujutsu world truly is unique.' He thought so, but he had seen enough.

The bucket list was almost entirely marked with black ink. Everything he knew was gained from his own research feather than his time spent observing in the void before his rebirth process began.

He he had very little knowledge of this world's unique characters and hence even less interest to see them. If anything, he was probably stronger than everyone else currently in existence.

Ultimately, there was very little left to learn from the "waiting room" that interested him. Perhaps it was time to move on. Of course, that was easier said than done.

Haruto looked at his small, pale hand. That was the core of the problem. This body was the perfect vessel to contain his power due to the laws of Jujutsu.

Over the past few years, The Infinite Boundary had long reached a state of 'Adaptive Autonomy.' No longer requiring any form of conscious focus to maintain the seal.

Of course this was in his relative normal state of mind. One he had maintained since the day of his birth and no knowledge of what would happen in a otherwise unstable condition, which shouldn't be a problem with reverse cursed Technique.

However, it was still matter. Retracting his consciousness would simply make this body an empty shell. Trying to take it with him was also a problem.

He couldn't return to the Void in this physical form. The moment his flesh touched that infinite pressure, it would disintegrate. Molecular bonds would fail and the atomic structure would collapse.

Nothing could exist there that wasn't in its purest form. Hence, going back the way he came was never an option.

He needed this body—or at least, he wanted it. It had taken 534 attempts to get one that worked. Throwing it away felt wasteful.

Solution: Don't go through the Void. Go around it.

Every reality existed as a separate frequency, like radio stations. This world was tuned to ~2847.3 Hz (his own measurement system). Other worlds would have different frequencies.

The dimensional barrier served as the "wall" between frequencies. In theory, all he had to do was use his cursed Technique to create a vector from this side of reality to the other. Then he could safely transition without touching the Void directly, effectively achieving Multiversal Travel.

However, therein lay several problems.

Haruto closed the book and looked to the distance only to see Mio laughing on the swings with flying pigtails. Following which, he focused his gaze on a patch of empty air three inches in front of him and stretched his arm out.

Problem #1: From his analysis and research. For a regular sorcerer, even if given his innate technique, perceiving the boundaries between realities was downright impossible.

Haruto had long since realized that His Innate Technique was unique.

Formed specifically to cater to his very existence as an outsider integrated into this worlds laws. But even then, he wasn't fully a part of it. For a regular Jujutsu sorcerer, there was no such thing as the concept of an "outside" to begin with, as universal laws alone were already extraordinarily complex. Space, time, reality, physics.

There were dimensions and sub dimensions and pocket dimensions and entire Micro universes within the confines of their environment. Trying to pierce through all that was like using a wooden stick to go through ten foot thick lead for a normal person.

A Jujutsu sorcerer would have that stick upgrading to anything from a wooden spear to laser depending on the nature of their innate technique.

To achieve what he wanted meant to innately know that there was more beyond that and to know exactly what that more was. Even then, perceiving said boundaries wasn't possible. So how could he do it?

The answer was simple. He came from the void itself. The nexus of all realities.

Haruto could do what no one else could. Just then, bus eyes narrowed as he actively used his cursed technique.

A lapse emerged in the cycling process as he made a second, micro entrance point for his void energy.

Unlike everyone else in existence, not only did his very nature and innate technique grant him that level of perception, he had a second consciousness in the void amplifying that perception.

He could literally see the space between dimensions and place his exit point there from a third person's perspective. Next, a crack appeared in the space in front of his fingers, expanding everything so slightly with each passing second.

Haruto raised an eyebrow at the sight but didn't push further.

Just from the first few seconds, he had already come to a definite conclusion. 'It can't be done this way.'

The Jujutsu world operated on balance and cursed energy left residues in their wake. Normally, sorcerers and cursed spirits could hide their residues to prevent being discovered after performing actions.

Unfortunately, that didn't apply to the current situation. 'This isn't even cursed energy anymore.' He was effectively opening a hole in reality with Void Energy—the purest, most volatile substance possible. Without a doubt, if he continued like this, he’d light up the Jujutsu world’s radar like a flare in a dark tunnel. It was nigh impossible to go unnoticed like this.

Haruto was certain that if he did so, the park would be crowded with Jujutsu Sorcerers in mere minutes.

It wouldn't be long before this was traced back to him. The troubles that would follow would be a headache to deal with. In that case, he would need a way to contain the aftermath while he experimented. First, a veil was out of the question.

No form of barrier made from cursed energy would suffice for his current actions. Ignoring the fact that a veil was rather eyecatching.

'Well .. I could try to contain it manually.'

The thought formed in Haruto's mind as he looked at his arm. 'However, my cursed Technique can't process that much. I'll have to use a Heavenly Pact.'

The Heavenly Pact. An aspect of Jujutsu Haruto was most intrigued by in the Jujutsu world. By intentionally handicapping one part of his biological or spiritual hardware, the universe’s underlying code allowed for a temporary "overclocking" of another.

It was a trade of equivalent values that governed the very flow of cursed energy and reinforced the fundamental logic of balance this reality seemed to adhere to. 'It's worth a shot.'

Spending a few seconds thinking of the terms needed to achieve his goal, Haruto formed a seal with both hands.

'Binding Vow: Total Sensory Closure,' he commanded internally.

The world vanished. His vision went pitch black. His hearing died. The smell of the park and the feeling of the grass beneath him ceased to exist.

For any other sorcerer, the terms of his binding Vow would be outright suicidal.

He had sacrificed 99% of his human "bandwidth" to the universe. In exchange, the mental resources usually spent on processing the 3D world were redirected entirely into his Innate Technique. Infinite boundary had three sets of apertures.

Each aperture commanded an entrance point and and exit point, and each could only be used on one thing at a time. The first was used for the automatic regulation of his energy from the void. For sacrificing hide senses, his second aperture was boosted to greater heights, overcoming the limited vectors it could track. His goal was simple.

To hide the energy fluctuations that would result from tearing a hole within realities, Haruto intended to sacrifice all awareness in to achieve a greater form of vector manipulation, using his second aperture to form a round sphere to redirect all pixels of light, sound, and energy fluctuations that would occur in a ten meter radius.

For an average sorcerer, such an action was practically foolish. Not only was the user unable to perceive the outside world, but they also had no sense of time, pain or motion. In simpler terms, they were practically defenceless.

The aperture sphere would only channel all vectors from escaping the sphere. Meaning any outward attack would still be able to kill him without resistance.

Worse still, without any senses to observe, there was no way he would be able to conduct the experiment he wanted to perform making the massive price paid to achieve the vow meaningless.
