My System: An Evolved Computer I Made With My Unique Ability—

The atmosphere above the Sea of Japan just got more intense as more reinforcements arrived for Satoshi's group, aiding them in the mutiny they were doing 'against' the government.

In hindsight, the decision of both the Japanese Government and the SAO was rash, and if their reasoning were made public, then the citizens would find it rather absurd. After all, destroying a Dimensional Portal is more complicated than it looks, and even if the Japanese Government were sure to limit the damages they would do when they attempted to destroy the Portal, it's a different case on the other end of it.

Meaning to say, that if a Dimensional Portal was destroyed, there's a considerable probability that the world on the other side of it would be severely damaged. It was obvious— the Dimensional Portal is a pure swirling mass of energy converging on its center. If the energy was repelled out and away, then that energy should affect something else due to the disruption.

With the Dimensional Portal destroyed, not only would the Urass Forest be wiped out, but the entire Nichijou Region where Ash and his family lives would be erased from their planet as well. Heck, they might even be erased due to the sudden outburst of energy which would have similar effects as a nuclear bomb hundreds if not thousands of times better.

That's why it's always advisable that the Dimensional Portals are left alone unless, of course, it was proven that the other side of it is a threat to their planet. WITH the exception that the other side of the Dimensional Portal is a threat.

But how could the Japanese Government and the SAO consider it a threat when they haven't explored the other side? Again, it was understandable since they were backed into a corner due to the Dungeon Spire appearing recently before the Dimensional Portal but such a decision was inexcusable. The topic of human lives is at play here, and if they aren't careful, they could be causing a massacre without even knowing they did.

Quite surprisingly, the masses were on the side of Satoshi on this one. They believed that such a harmless Dimensional Portal shouldn't be dismantled just because of its potential threat.

"They should at least assist the number one hero in the Dungeon Spire instead of attacking the Dimensional Portal,"

p "Time and time again, Dimensional Portals appeared in our world and those looking like that are harmless,"

"What would they gain from destroying such a passage to another world? It might even have resources that we don't have here on our planet right now."

"Look, if they're short-staffed on explorers right now, I'm sure quite a lot of people would volunteer to explore the other side of that Dimensional Portal. It's a real-life isekai, no one would say no to that sheet."

"Yeah, what the other guy said. I'm sure hundreds of people would explore that."

These people were the ones interviewed by the reporters who were at the shoreline, watching the battleships battle it out with the superheroes who came to Satoshi's aid. They may not be as formidable as Satoshi but they managed to hold the fort just like what they intended to do.

.....

Eugen Hood, the Chief of Navy Operations, is the one in charge of this entire operation. And seeing a bunch of teenagers standing up to him gave him a great blow to his pride. He clenched his teeth to the point they chattered as he pounded his fists on the railings (he was standing by the edge of the battleship). "You know what... fine. Even if you're not worth seeing my superpower, I'll show you the difference between our abilities." Eugen Hood said to himself, tightening his tie and adjusting his marine cap before he stood on the railings.

It was an unnecessary movement but it did the trick of attracting Satoshi's four classmates, as well as the other superheroes whom Eugen Hood sent to engage them in combat.

Water Creature Manifestation.

A ripple, and then a huge whirlpool appeared right in the middle of both sides, growing bigger and more ominous as seconds passed. A roar was heard, coming from the depths of the sea as the whirlpool got bigger and bigger. It was like  a yawning chasm in the middle of the sea, threatening to swallow anything and everything that came near it.

The supers  who were part of the army knew what was about to come down and so they retreated without a second thought. They knew just how powerful Eugen Hood was and they don't want to get caught in the crossfire of his superpower. On the other hand, Hiroshi and the others remained right in front of the Dimensional Portal, still defending it at all costs despite the pressure they felt from the ever-growing hole in the sea.

A few seconds later, the whirlpool on the sea was large enough that it could easily swallow a battleship at this point.

the roars continued to grow louder, and there were multiple of them. There were grunts, whale calls, and roars coming from the hole all at the same time, and as if that's not scary enough, the bottom of the huge whirlpool looked like a dark portal straight out of a horror science fiction.

The first Water Creature Manifestation that came out was none other than a Knifehead (or at least it looked a lot like a Knifehead), one of the category threes in a certain series with giant beasts and giant man-powered robots fighting for the planet earth. The beast looked like a shark, a huge shark that has arms and legs and is easily five times larger than a battleship. Its body was wholly composed of water.

With a roar, the gargantuan monster stood face to face with Kuroe and the others, staring at them as if it was looking right into their very souls. Kuroe felt an intense bloodthirst from the beast even though she knew that the beast was just a manifestation in the water.

Hiroshi's group thought that they'd already seen everything, but before they could sigh in relief that there was only one monster, a huge tentacled monster came out, resembling a Kraken. And as if that wasn't enough, three more gigantic monstrosities spawned behind the Knifehead, creating an army of giants that seemed impervious to small-scale attacks.

"Now that's more like it!" Hiroshi shakily said as he put his fists together.
