As for how the Lease Devil determined whether someone could repay the borrowed aura, Ronin had already guessed it.
It came down to interest and the borrower's own aura reserves. When the two reached a balance point, that was the threshold. Once the borrower crossed it, the Lease Devil would choose to forcibly extract the borrower's aura to make repayment.
Ronin's guess was correct.
Milia's profit came from the interest collected after lending out aura.
When she developed her Nen ability, she made a Vow and Limitation: from the moment she gained the ability to lend out her aura, her own training would no longer increase her aura capacity.
But the interest she earned could continuously raise her aura capacity—and that increase could even stack again and again.
However, to make this work, the borrower had to fully understand the rules and voluntarily sign the lease contract.
At the same time, if she wanted to receive interest via the Lease Devil, she also had to exchange money into points to purchase it.
In other words, from the moment she developed her ability, every cent she earned would be converted into points—becoming the tool she used to grow stronger.
That was one reason she earned a lot yet cared obsessively about money.
Heavy restrictions—rewarded by the immense power of a strict vow—gave her limitless potential.
Ronin wasn't the first Nen user she'd approached. Before him, she'd already made several people famous.
Now that she'd reached Ronin, Milia was certain he wouldn't refuse to borrow aura from her. At least for now, the expected payoff clearly outweighed the risk.
Milia quietly lowered her hand. She always felt Ronin's eyes drifting to her hands now and then.
"My 'numerical evaluation' is just my personal method," she said. "It's not perfectly accurate.
Normally, aura inside a Nen user comes in two forms.
One is visible aura—the amount you release outward. That's the amount you can actually use at a given moment. The upper limit increases with training, and in special circumstances you can even burst beyond that limit.
As an Enhancer, you should understand this best. In your fight with Greg, that last punch you threw—your visible aura output in that instant exceeded your normal maximum."
Ronin understood what she meant.
Big Bang Impact plus Cherry Blossom Impact.
In that moment, the force he unleashed really did far surpass his usual peak.
"The other form is latent aura—the amount stored inside your body. Its upper limit also increases with training," Milia explained patiently. "I estimate your latent aura by observing your visible aura output."
Ronin adopted a humble, listening posture.
"My estimate is that the maximum visible aura you can sustain outside your body with Ren is around 700," Milia said, a glint of insight flashing across her lenses. "Multiply that by ten, and you get your latent aura—so roughly, your latent aura should be around 7,000 to 8,000.
Of course, that's a very rough estimate. For something precise, you'd need to fight me, or let me see your Ken and how long you can maintain it."
Not even ten thousand?
Ronin was surprised.
Still, it wasn't a low number—certainly not for someone who'd only awakened Nen a little over a month ago. If anything, it was high.
After all, when Gon was trained by Biscuit around the Greed Island period and into the Chimera Ant arc, his aura capacity was only a bit over twenty thousand—and that was after a stretch of Biscuit's training.
Ronin having this much aura was largely because two pairs of Scarlet Eyes had forcibly boosted him.
By that logic, Milia's aura capacity was probably around fifteen thousand—or more. She likely wouldn't lend out every last drop of her aura with no defenses.
And with that calculation, it also neatly matched Ronin's earlier guess about the Lease Devil's forced repayment rules.
Borrowing double for ten minutes would create interest of around 7,500—right around Ronin's total latent aura.
If he borrowed double from her, Ronin's overall aura would reach roughly 22,500. With that much aura against Uvogin… there really might be something there.
Because by his calculations, before fusing the second pair of Scarlet Eyes, his burst output was probably only around 400. Even forcing it higher with Cherry Blossom Impact, it would at best match his current baseline—enough to give Uvogin only light injuries.
Now, a normal punch was already at that level. And if he fused Big Bang Impact with Cherry Blossom Impact again, the destructive power would be on an entirely different level.
There was a real chance.
"You haven't been awakened long, have you?" Milia mistook Ronin's silence as disappointment at the number and tried to encourage him. "You've trained for a short time and already have an aura capacity this large—you're a genius among geniuses.
Among all the outstanding people I've met, you absolutely have the strongest talent and potential."
"Thanks," Ronin said. He slid the contract back toward her for now. "I'll borrow aura from you—but not yet. I'll wait until it's confirmed the Troupe will face me on the ring."
Milia's contract specified a maximum leasing period of three days.
Meaning: within three days after borrowing her aura, Ronin could activate the borrowed aura at any time through communicating with the Lease Devil.
If he didn't use the borrowed aura during those three days, then when the Lease Devil departed, it would only collect 5% of the borrowed aura as interest and leave.
But if Ronin really did that, Milia—after losing a massive amount of aura—could end up in a dangerous situation. So he didn't sign the contract immediately.
"Alright," Milia said. The instant she touched the contract, both it and the floating Lease Devil vanished.
Uvogin had issued his challenge—clearly intending to fight him on the ring.
If Uvogin hadn't been to Heavens Arena before, it would take him at least several days to fight his way up to the 200th floor.
That window was Ronin's final preparation time.
Still, Ronin also needed to be careful—guard against Shalnark making a move from the shadows. Manipulators were troublesome, especially because Ronin couldn't keep the Sharingan active all the time to scan his surroundings.
In that case, it would be hard to confirm whether someone approaching him had one of Shalnark's antennas on them.
"Oh—one more thing," Milia said. "You should give me the Phantom Troupe members' information in advance. That way I can prepare early and maximize the profits from the ring match."
"You should be careful too," Ronin warned. "If you start promoting too early and expose their identities, I'm worried they'll come after you."
"Fair point." Milia didn't try to act tough. "A bunch of lawless, bottom-feeding scum like them really does require caution."
The Phantom Troupe were A-rank wanted criminals, and combined with Ronin's cautious attitude, it was clear their strength was formidable.
Milia had confidence in herself—but not the kind of confidence that turned into arrogance.
