Chapter 26 - How to Accidentally Become a Trillionaire (and Break Magic)

Rias leaned back in her chair, regarding me with that same composed, calculating gaze she always had when dealing with things beyond her expectations.

"Alright, Malrik," she said, tapping a delicate finger against the armrest. "Since you seem so confident in the value of your items, let's make this simple. I'll offer you what I believe is a fair trade."

She lifted her hand, and in an instant, a deep red magic circle formed in front of her.

A book—a grimoire radiating powerful devil magic—appeared mid-air before gently landing on the desk.

Next, she reached into another small summoning circle and produced a crisp, high-value Devil Contract—one that, upon activation, would transfer an enormous amount of wealth.

"This," she gestured to the book, "is an ancient grimoire on High-Class Devil Magic. Some of its spells and theories are exclusive to noble houses."

Her fingers glided over the contract. "And this will deposit ten billion yen into your account instantly."

She folded her hands together, watching me carefully.

"That should be a reasonable exchange for the kinds of weapons you're capable of making."

The room was silent.

Akeno smiled, amused.

Koneko still chewed her cookie, but I noticed her ears twitch slightly.

And I?

I was internally grinning like a madman.

This was the perfect chance to test my system's true limits.

"Alright, deal."

I reached forward, grabbing both the grimoire and the contract.

The moment my fingers made contact—

[Ding!]

[100X Multiplier Activated.]

- Grimoire of Devil Magic

- 1 Trillion Yen Deposited.

I felt my breath hitch for just a second, but I quickly masked it with my usual smirk.

Holy sh*t.

I just made a trillion yen in an instant.

This system is ridiculous.

Casually, I stored the items in my personal spatial inventory—making sure to hide the multiplication effect so no one noticed.

Rias and Akeno blinked.

"Oh?" Akeno mused, tilting her head. "You can use space magic, Malrik-kun?"

I shrugged, feigning nonchalance. "Basic magic tricks, really."

Rias raised an eyebrow. "Most humans can't do that so easily."

Koneko, ever the blunt one, narrowed her eyes slightly. "Suspicious."

I chuckled. "I like to keep some surprises."

Rias tapped her fingers on the desk, still watching me closely.

"Interesting," she murmured. "Very interesting."

Meanwhile, inside my head—

"Holy hell, I just broke the economy."

———————————

I strolled out of the Occult Research Club, keeping my expression cool and composed, but inside?

I was barely holding in my excitement.

The moment I was out of sight, I pulled out my phone.

[Balance: 1,000,000,000,000 yen]

I stopped mid-step.

Stared at the screen.

Holy sh*t.

I had just become a trillionaire overnight.

The kind of wealth that could buy countries.

No, the kind of wealth that could reshape the supernatural world if I wanted.

"Yeah… I need to get home. Now."

I picked up the pace, keeping my cool as I walked past clueless students. They had no idea a literal money god was among them.

I shut the door to my room, locked it, and immediately summoned the grimoires from my inventory.

The dark leather tome floated before me, its cover glowing faintly with runic symbols.

Title: Grimoire of Devil Magic.

Alright.

I already knew this book was supposed to contain advanced high-class Devil Magic from Rias' lineage. It was rare, valuable… but nothing insane.

Except my system multiplied it 100 times.

I took a deep breath and flipped it open.

Page 1: Fundamentals of Demonic Energy Control.

Page 10: Intermediate Fire and Shadow Manipulation.

Page 50: High-Class Devil Spells – Forbidden Techniques.

Page 100: Ultimate-Class Magic. Theoretical Applications of Beelzebub's Spatial Manipulation.

…

…

Wait.

I kept flipping.

The deeper I went, the more absurd it got.

Page 300: The Lost Magic of Lucifer's Bloodline.

Page 500: Transcendence Theory – Magic Beyond the Underworld.

Page 800: Abyssal Sorcery – Magic Techniques Used by the Gods of the Nether.

I slammed the book shut, my heart pounding.

This wasn't just some high-class devil spellbook anymore.

This was ALL Devil Magic.

Every spell, every formula, every forbidden and lost technique—it was all inside this grimoire.

A perfect collection of EVERY known devil spell across time.

And I?

I wasn't even a devil.

A slow grin spread across my face.

"I think I just broke the magic system."

If I could learn this, and then combine it with human magic, fallen magic, and even divine magic…

I wouldn't just be a strong human.

I'd be the first being in existence to master multiple supernatural disciplines.

I sat back, staring at the book in my hands.

The supernatural world had its rules. It's systems. Its limitations.

And me?

I had just found a way to ignore them.

"Let's see how far I can push this."
