After Crushing the Final Boss, I Got Infinite Mana and Returned to Earth ～With Cheat-Level Power, I’ll Rule Both the Game World and the Real World～ - Chapter 02: Since I Finally Got This Power, It’d Be a Waste Not to Use It

Chapter 02: Since I Finally Got This Power, It’d Be a Waste Not to Use It

Hello everyone.

I’m Georg—the guy who burned the forbidden grimoire sealing the Evil Dragon Diabel and, as a bonus, scored myself a cute dragon mascot and infinite magic.

This overwhelming, godlike feeling is addictive.

So this is what “getting carried away” feels like, huh?

“Hey! Hey!! You!! Enough already!! Give me back my magic, now!!”

“Nope.”

“Whyyyyy!? You said you gave up on magic, didn’t you!!”

“Most humans are dumb creatures who can’t keep their promises. I’m one of them.”

Early morning.

The moment I opened my eyes, a tiny black dragon was whacking me on the head with its tail.

In the game, this Evil Dragon tried to destroy the world… but like this, it’s just adorable.

Still, it’s ridiculously persistent about getting its magic back.

What’s mine is mine.

What’s yours is also mine.

Evil Dragon Diabel’s magic? Belongs to Evil Prince Georg now.

Time to try one of the spells I’d read in those grimoires.

“—Dominate Family.”

“Gweh!?”

I finished the chant, and the spell activated.

In an instant, chains of magic shot out from the array and wrapped Diabel up like a mummy.

Then, as if melting into his body, the chains disappeared.

Dominate Family.

A spell designed to tame wild monsters.

And since Diabel was technically a monster too, he counted as a valid target.

Normally, it only worked on weaker creatures.

But Diabel had zero magic now.

Meanwhile, I had infinite magic.

So yeah—total cakewalk.

The moment Diabel realized what kind of situation he’d been forced into, he exploded with curses.

“Y-You!! You fiend!! Using my own magic to enslave me—do you have no heart!?”

“Well, it’d be a waste not to use power I worked so hard to get.”

“Monster!! Demon!! Heretic!!”

Now that I think about it, this was kind of weird.

In my previous life, I was the type who tried to live steadily, humbly, without abusing power. A serious person.

And yet here I was, throwing my strength around however I pleased, practically drunk on it.

In the game, Georg was a cold-blooded man who’d do anything for power. But he was never this reckless.

If anything, he was careful and crafty—constantly setting traps for the hero who kept trying to kill him.

Maybe my past-life memories and Georg’s original self had fused in some strange way, and that was causing this sudden personality shift.

Well, it wasn’t really a problem, so… let’s not overthink it.

More importantly, a pet who calls his master an “Heretic” needs to be properly trained.

“Hurry up and give me back my magic—”

“Sit.”

“Gwah!? M-My body’s moving on its own!?”

“Shake.”

“Guh! M-My paw! It’s moving against my will!!”

Diabel sat and offered his paw exactly as ordered.

Even while his mouth resisted, his body obeyed me—just like the Shiba Inu I’d had in my previous life.

Adorable.

“Well then, what should we do today? I’m in such a good mood now that I can use magic. Maybe a walk would be nice.”

“C-Curse it… how can anyone stop this monster!?”

I headed out for a stroll, humming happily to myself.

Even without succession rights, I was still a prince of the Magiluke Kingdom.

Of course, that meant I could only walk around the royal courtyard—but it was spacious enough. More than enough for a pleasant walk.

The trees and grass in the courtyard, which had never caught my eye before, suddenly looked beautiful.

Maybe it was because I could use magic now.

The whole world seemed to shine.

And then—

Cheers suddenly erupted from the knights’ training grounds beside the courtyard.

Curious, I wandered over and found a boy younger than me surrounded by knights, being showered with praise.

“As expected of you, Prince Bavek!!”

“To have mastered advanced magic at only thirteen—Your Highness is a true genius!!”

“You’re nothing like that useless Prince Georg!!”

…Wait, was that last part really necessary?

The one being celebrated was my younger brother, the third prince of Magiluke, Bavek von Magiluke.

In the game, he was just a background mob—killed off by Georg after gaining power. Mentioned by name, and that was it.

Now, he was basking in knightly praise for mastering advanced magic.

And judging by his smug expression, he was eating up every word.

“Hmph, of course. Don’t lump me in with a talentless fool unworthy of the royal bloodline. …Oh? Speak of the devil.”

Uh oh. Looked like Bavek had spotted me.

For a second, I considered turning tail and running—but that wasn’t my style.

So instead, I straightened my back, walked proudly, and stopped right in front of him.

“You usually cower and run off the moment I speak to you, but today you’re standing your ground. How unusual, dear bro-ther.”

“Well, I see no reason to run. Besides, it’s such a nice day, isn’t it?”

“…Hey. Incompetent fool.”

I brushed off his snide remark, and his whole attitude shifted.

Clearly, he didn’t like the fact that I wasn’t trembling for once.

“How dare you act so casual with me! I’m third in line to the throne!! You, a failure with no succession rights, have no right to act high and mighty!!”

“Such an unreasonable claim. Still, it’s cute—very childlike, really.”

“Y-You dare mock me!? Fine then! If you’ve got that much mouth, I challenge you to a duel!!”

With that, Bavek ripped off his glove and hurled it at me.

Picking it up meant accepting the duel.

Honestly, duels were nothing but a pain… but I wasn’t made of stone.

Some things did get under my skin.

And so, I decided to accept.

After all, the insults I’d swallowed all this time had been piling up.

I’d pretended not to care when I had no power to fight back—but deep down, maybe I’d been simmering in frustration all along.

“What’s wrong? If you plan to run, now’s your chance. If you cry and beg for forgiveness right this moment, I might be generous enough to let you go—”

“Very well. Let’s duel.”

“…Hah?”

“But if I win, I’ll be taking your right of succession to the throne.”

“Wha—”

Bavek froze in shock.

Not that I really cared about succession rights, but phrasing it that way made for the perfect provocation.

As expected, his face turned red with rage and he shouted his agreement.

“Fine then!! I’ll cripple you so badly you’ll never walk again!!”

“Good. Then it’s settled. The knights here can act as witnesses.”

“H-Hey, you!! Are you seriously going through with this!? What if the whole capital gets destroyed again like last night!?”

Diabel flapped his tiny wings in a panic, whispering at my side.

True, even a beginner spell had wiped out half the city, so if I got reckless, it wasn’t just the capital—the whole kingdom could end up in ashes.

But with Diabel’s infinite magic, I could always rewind time, repair the damage, even revive the dead.

For now, venting years of pent-up frustration took priority.

And then it happened.

Bavek’s gaze shifted toward Diabel.

He sneered, then spat out an insult.

“What’s this, brother? That fat lizard of yours? So you’ve started keeping filthy little pets now?”

“…Oi. Georg.”

“Yes, what is it?”

A vein bulged on Diabel’s forehead as he spoke, his face twitching with fury.

“Crush that little brat in my stead!! I don’t care anymore—use my magic however you like!! Just kill him, no matter what!!”

“Even when you’re furious, you still look more cute than scary in that form.”

With Diabel’s… enthusiastic cheer behind me, I bent down and picked up the glove, officially accepting the duel.

The knights looked completely dumbfounded at how fast things had escalated—but oh well, not my problem.

I stepped into the center of the training grounds, faced Bavek head-on, and waited for the signal to begin.

―――――――――――――――――――――

[Afterword]

One-Point Diabel

Because he had shrunk down with only tiny little wings, outsiders saw him as a chubby lizard.

Stripped of his overwhelming magic, his arrogant personality had softened a bit.

If you thought, “Diabel’s kinda cute,” toss me those ★s!
