Rebirth As Godzilla

After a while, Belial noticed something strange. The anxiety he'd been feeling constantly just… faded away. It was like his brain had finally accepted it: he had all the time in the world. 

If this were one of those typical isekai stories where the hero gets summoned to defeat the Demon King, maybe he'd have a clear mission or some grand goal. But no, he didn't get isekai'd as a Hero.

He came back as Godzilla. And with that, no one handed him a prophecy or a quest.

Whether you looked at it from a dragon's perspective or a kaiju's, his life span was ridiculous. He could live for centuries, maybe longer, without anyone being able to do a thing about it. 

So instead of rushing off to save the world or anything, he just focused on getting stronger, absorbing mana nonstop, devouring anything edible. 

That was the goal: become powerful enough to walk freely across this world without worrying about being hunted or killed.

What would he do after that? 

Honestly, that was future Belial's problem. It's not like he wanted to become some invincible ruler or wage war on kingdoms. He just wanted to be strong enough to go wherever he wanted, mess around, and not die in the process. 

That kind of goal didn't need to be rushed. As long as he didn't attract too much attention, it was just a matter of time. 

Even if it took hundreds or thousands of years, he'd eventually get there. Worst case, he could just take long naps to pass the time.

Without realizing it, Belial's sense of time had already begun to shift. Still, he couldn't fall asleep right now. So, to kill time, he decided to explore what this body could do.

He started with Godzilla's basic abilities, testing his limits, pushing the gravitational vortex to see how long he could hold it, and flicking the photon reflection shield on and off like a bored kid playing with a flashlight. 

Whether that kind of training actually helped, he had no idea. For a creature like Godzilla, training felt pointless. His strength would naturally increase as his energy did.

Once he got bored of testing brute force, he turned to something new. Something that wasn't originally part of Godzilla, mana. 

Before, any mana he absorbed was instantly used by his atomic core, feeding the endless hunger of his reactor. He could devour all the mana in a city and still not be able to use any of it directly. 

But now, with his body constantly sucking in ambient mana and recycling it through his energy field, he finally had some to play with.

At first, he went with his usual approach, brute-forcing it. He tried stuffing mana into Godzilla's natural powers like Space Claw or embedding it into the energy field to strengthen its functions.

But then he got curious. What would happen if he just tried releasing mana outward?

Back when he was human, Belial wasn't exactly a genius. And honestly, that hadn't changed. 

Even trying to "externalize mana" was a stretch for him. He could barely circulate it inside his body, let alone figure out how to project it. 

Where was the output port even supposed to be? 

He had no clue. But it didn't matter. He had time now. There was no pressure. 

The energy field could keep running in the background while he fumbled around. So, he kept trying. Over and over. 

Days? Months? Who knew how long it took. But eventually, through sheer stubbornness, he managed it. 

He learned how to release mana outside his body. No grand awakening, no sudden inspiration. Just grinding the same motion until it worked.

He stared at the faint, static-like mana dancing on his massive fingertip. It was unstable and weak, but that didn't stop him. 

He kept at it. He tried cranking up the output next. 

Before long, he could fire a thin mana beam from his mouth, like a light cannon. It did some damage, sure, but it wasn't efficient. The mana cost was way too high for what it did.

Could he boost the output to make it deadlier? Probably. But it felt like a waste. It was just another flashy breath attack, and he already had plenty of those. 

There had to be a better way to use mana. Something that made it worth the effort.

That's when it finally clicked. Magic.

"Wait… this is another world."

How had he forgotten that? Magic was one of the core tropes of these kinds of worlds. He remembered the battle he'd had with that old man a while back, how that guy had summoned a magic circle in the sky. 

At the time, Belial had been too caught up in the fight to think much of it. But now, the memory felt sharper, clearer, like everything was recorded in HD.

Then he remembered the little girl and the ring she gave him. Digging through his spatial ring, he pulled it out, along with a stack of books and some weird tools he couldn't make sense of. But one thing was certain, the real experimentation was just getting started.

Some of the books had diagrams that were clearly magic circles, filled with runes, geometric shapes, rings, triangles, and strange patterns that looked almost like circuit boards. 

A few even had 3D illustrations. Whoever wrote these definitely put a lot of effort into them. 

So naturally, Belial gave it a shot. He tried shaping his mana into magic circles in midair.

It turned out to be way harder than he expected.

He had just figured out how to release mana in the first place, like barely getting a faucet to work. Now, he had to control the flow, cut it off, and still keep the released mana stable and in place. 

Even something as basic as preventing the mana from vanishing once the flow stopped took him forever to figure out. Holding it steady in the air and forming specific patterns? That was a whole new level of frustrating.

Eventually, he had an idea. What if he didn't have to draw in the air at all? What if he just used a physical surface instead?

Any solid material would work, stone, for example. So Belial gathered mana at his fingertip, then carved into stone using his claw like a chisel. 

That was way easier, even if sometimes he pressed too hard and shattered the entire thing. Later, while out hunting, he had another thought, maybe he could draw magic circles on animal hides after skinning them.

"Now this… this feels like something our ancestors would do," he muttered.

It was a solid idea, and in theory, it worked. But his size and claws made it hard to avoid ripping the hides apart. 

It just wasn't worth the trouble. So he went back to carving into stone. Skinning things by hand wasn't exactly fun anyway.
