The benefits that the exclusive world brought to Arthur were truly immeasurable.
Originally, he had assumed that aiming for a perfect clear would force him to keep skipping floors.
If that were the case, much of his accumulated knowledge from various anime worlds would end up going to waste.
But now, he had Saeko Busujima.
And in the future, others bound to him through contracts would also gain the qualifications of Reincarnators.
There was no reason to let valuable opportunities slip away.
Rather than selling certain strategies or letting outsiders benefit from them, it made far more sense to use trusted companions to explore and take advantage of the Reincarnation Space.
It was both efficient and reliable.
One important detail worth noting.
Saeko Busujima's Reincarnation Tower progression was completely independent from Arthur's.
Her clear records were calculated separately.
She could only enter dungeons on Arthur's current floor when acting as his contracted companion.
Under normal circumstances, she would still need to climb the Reincarnation Tower from the very beginning on her own.
Arthur wasn't worried about her in the slightest.
The moment he realized that contractors could be enhanced, he decisively pushed Saeko Busujima's four-dimensional attributes straight to their limits.
Saeko, who had originally planned to rely on her own strength, couldn't help but complain with a faint smile that he was spoiling her too much.
She knew, at least vaguely, how precious Reincarnation Points were.
Arthur merely chuckled.
She was his girlfriend, his companion, someone who would stand by his side in battle. If he didn't spend resources on her, who else should he spend them on?
Saeko Busujima's original master-level swordsmanship was already more than enough to dominate most dungeons below the 10th floor.
Even if she entered alone, worlds like Highschool of the Dead posed no real threat to her.
As for the other dungeon worlds, most of them were nothing more than peaceful slice-of-life environments.
And now, with her physical abilities enhanced to the absolute peak a normal human body could reach—
Two words summed it up perfectly.
Utterly invincible.
Arthur had never planned to hoard all his Reincarnation Points.
Low-level dungeons simply weren't dangerous enough to justify excessive caution.
Besides, he had far more points than he could realistically spend.
When you were rich, being a little extravagant wasn't a sin.
"…That said, there really isn't much left for me to spend them on."
Enhancing his own physical attributes to the maximum had cost less than 40,000 points.
After accounting for Saeko Busujima's contract fee and enhancements, he still had around 150,000 left.
Until he obtained a special physique or bloodline capable of breaking the natural limits of the human body, further attribute upgrades were impossible.
That left only one option.
The skill he had obtained from the lottery.
"System, enhance my skill, 'My Style Swordsmanship.'"
"[Confirmed. Reincarnator Blank possesses 'Master-level • My Style Swordsmanship.' Current proficiency: Minor Accomplishment.]"
"[Enhancing to 'Major Accomplishment' requires 50,000 Reincarnation Points.]"
"[Do you wish to proceed?]"
"Enhance."
"[…Enhancement successful.]"
"[Skill upgraded to 'Master-level • My Style Swordsmanship.' Evaluation rank increased: S+.]"
A sudden wave of enlightenment surged through Arthur's body.
It felt as though decades of real combat experience with the sword had been forcibly engraved into him, accompanied by a crystal-clear understanding of its very essence.
"So this… is the difference between Minor Accomplishment and Major Accomplishment?"
If he had to give a concrete example—
It was like comparing an LoL solo-queue king to a true top-tier professional player.
Before, he had merely stepped into the realm of master-level swordsmanship.
He understood many principles, but they were still fresh concepts—knowledge that required time, repetition, and real combat to fully digest.
He needed to temper it through use.
But now?
It was as if time itself had been skipped.
All those experiences, refinements, and realizations had fused together in an instant.
The feeling was exhilarating!
Arthur glanced at the next enhancement stage.
[Master Peak level — 100,000 Reincarnation Points.]
"…Yeah, I'll pass for now."
Advancing too fast wasn't necessarily a good thing.
More importantly, it lacked a sense of grounding.
His newly upgraded master-level swordsmanship hadn't even had time to settle, let alone be tested in actual combat.
Upgrading it again immediately would feel hollow.
Strength needed contrast.
Effort first—then breakthrough.
Since skill enhancement was temporarily off the table, Arthur shifted his focus.
"Then… where else can I spend money?"
He pondered seriously, only to realize that for once, he genuinely couldn't think of anywhere to burn his points.
And then—
"Oh. Right. The warehouse."
He had actually forgotten something so fundamental.
Personal backpack.
System warehouse.
Storage space.
These were practically standard-issue cheat features!
Naturally, the Reincarnation Space hadn't overlooked this either, instead packaging it neatly as a paid service in the mall.
"[Personal Warehouse]"
Activation cost: 1,000 Reincarnation Points.
After activation, expanding storage cost 100 points per cubic meter.
However, once storage exceeded 10 cubic meters, the price increased sharply—
1,000 points per additional cubic meter.
Arthur stared at the pricing for a moment.
"…So that's how you get people to spend money."
Overall, even a single cubic meter of storage space was more than enough for the vast majority of Reincarnators.
In many low-level dungeons, this ability alone already bordered on the miraculous.
And in certain special situations—if one prepared key items in advance in the real world—it became absurdly convenient.
However, the initial activation cost of 1,000 Reincarnation Points created a noticeable barrier for novice Reincarnators, who were often tight on resources. As a result, very few people chose to unlock it early on.
That said, once a Reincarnator reached around the 10th floor—
As long as they diligently challenged dungeons for a few years while steadily strengthening themselves, saving an extra thousand Reincarnation Points was hardly difficult.
At that point, activating a personal storage space and purchasing a single cubic meter became an obvious choice.
After all, the cost-performance ratio was simply too good.
Of course, Arthur didn't need to worry about any of that.
He activated the Personal Warehouse without hesitation.
Then—
He purchased a full 100 cubic meters of storage space.
Just like that, over ninety thousand Reincarnation Points were spent in one go.
On top of that, he opened a 10-cubic-meter storage space for Saeko as well—and despite her clearly resentful look, he leaned in and kissed her without a word.
Perfect.
"Saeko, are you really not coming with me?"
Saeko Busujima shook her head gently.
"Darling… my body has just undergone a major enhancement. I still need time to get used to this power."
Unlike Arthur, whose strength was largely granted through the Reincarnation Space,
Saeko Busujima was a martial artist through and through.
Her original strength had been cultivated step by step through real training and discipline. This sudden leap in physical ability left her feeling slightly unbalanced.
She needed time to adapt.
However, once she fully adjusted
Even compared to Reincarnators with similarly maxed-out stats, the strength she could exert would be superior.
After all, one side had gained power they would have eventually reached through training.
While most Reincarnators received power abruptly, bestowed by the system, requiring time before it could be truly mastered. Until then, their strength often felt somewhat… hollow.
Of course, overwhelming level advantages could solve most problems.
Just like Arthur.
What he possessed wasn't an ordinary skill.
It was Grandmaster-level swordsmanship.
Unlike game-like abilities, where one simply calls out a skill name and activates an effect...
"My Style Swordsmanship from master Busujima" carried with it the accumulated experience, insight, and legacy of a true sword grandmaster.
It was equivalent to inheriting an entire lifetime of mastery.
Even if he couldn't fully wield it yet, the boost to his overall combat power far surpassed that of ordinary skills.
"…Alright then."
Arthur didn't intend to force Saeko.
Although this was the first time both of them had experienced such drastic enhancements, and the increase in physical constitution had inevitably intensified certain desires.
They clearly didn't want to be apart for even a moment.
Still, priorities were priorities.
And in moments like this, Arthur was surprisingly rational.
"I'll be back within a day. Wait for me at home, okay?"
Saeko Busujima reached out and gently adjusted his collar, moving with the familiarity of a wife seeing her husband off to work.
"Have a safe trip."
Mua~
Arthur froze for a brief moment and smile.
Saeko smiled at him back, warm and teasing.
"That's a goodbye kiss."

The inevitable is approaching, and I've been asking myself lately… should I write romance and +18 content in this dungeon?
I mean, I'm way too young to go to jail now, right? Our protagonist is over 20, and the girls in this novel… well. Yeah. 😶🌫️
