The All-Powerful Chūnibyō Champion

This shows that the island has been 'contaminated' by His power.

Such a level of power is undoubtedly beyond the comprehension of mortals, and can be described as 'indestructible'. Even nuclear bombs, which are touted as humanity's ultimate weapon, cannot destroy such an existence.

Clearly, even under the suppression of heaven and earth, the essence of the demon god still exists, and the upper limit of the power it can exert far exceeds its current level.

"It's not easy for you to have reached this level."

"Unfortunately, they didn't choose to run away, but chose to face me."

"You'll understand soon enough."

"Even gods can be killed and die."

With a casual gesture, the Sword of Dugu Qiubai materialized out of thin air between heaven and earth.

"Hehehe..."

Amidst the cold laughter, the earth cracked and mountains collapsed. All the trees on the island grew violently at the same time, with thick roots stretching for tens or even hundreds of meters and rising from the ground. If swung around, each branch could easily snap a building in half.

The figure in the air appeared so small at that moment.

Many government officials witnessed this and were all dumbfounded, standing there speechless.

They could hardly believe that such a power existed in the world.

"A nuclear bomb... should be able to destroy it, right?"

Someone wiped away their sweat.

But someone else shook their head and said, "Nuclear bombs have a large destructive range and terrifying radiation, but that's only for humans. For something so indescribable, we can only hope that the temperature at the center of the nuclear explosion will be enough to vaporize it..."

But no one was sure, because there were too many strange abilities in this world, and unless the opponent stood still and took the hits, it would be difficult to achieve a complete effect.

"Ah!"

Suddenly, a scream rang out.

"What's wrong!"

When everyone looked again, they saw a dazzling sword light piercing through the vast sky and earth.

The white clouds resemble parted ocean waves, and the branches and roots that have sprung up along them remain still at this moment.

"Boom..."

Countless trees fell to the ground, kicking up dust and sand, their broken surfaces revealing smooth, mirror-like cuts.

"This sword..."

Otherworld Demon God couldn't help but feel apprehensive.

Such power far exceeds the strength of other weapons of the same level.

His premonition was indeed correct; this mysterious visitor was indeed an opponent He needed to take seriously.

But...

"Your power is indeed formidable, but the timing is in my hands!"

As His voice fell, the heavens and earth seemed to respond, echoing with thunder.

"What is that!?"

The girl who was watching from a distance suddenly looked up.

Countless spatial rifts suddenly appeared in the air, seemingly connecting to another strange world within that void-like maw. An inexplicable aura emanated from it, filling the surrounding environment, while the aura of the Otherworld Demon God surged accordingly.

"I see."

Hasegawa Izumi straightened her expression.

"Before the world is about to change again, you can break free from this constraint by connecting with your own world, borrowing more power from your original self to overcome the bottleneck of your power."

He said it so casually.

The Otherworld Demon God couldn't help but feel a little surprised.

"Since you understand, you should know how big the gap is between us now."

After all, the gap between each level widens as strength increases, not to mention that His divine nature far surpasses that of mortals.

Why do you think that only you can do this?

Hasegawa Izumi, with an arrogant expression, took a step into the sky.

At that moment, his power also surged into an even higher realm.

"Impossible! You shouldn't have any leverage to rely on."

Even a powerful Otherworld Demon God looked puzzled.

"If it doesn't exist now, it will exist in the future."

The other party's next response surprised Him even more.

"Amazing!"

With a loud shout, the towering tree transformed into a figure over two meters tall, radiating green Demonic Energy. Its appearance was somewhat similar to a human, but even more sinister.

"Now I will fight you in my true form!"

The Otherworld Demon God clapped its hands, and trees and Demonic Energy coalesced into a giant hand, mimicking the action.

Under immense pressure, Hasegawa Izumi remained unfazed and delivered another slash.

"Heaven-Slaying Sword Drawing Technique!"

The Sword Qi was indestructible, instantly dismembering the giant hand.

However, all the wounds healed rapidly beneath the wildly growing trees.

"Bang!"

The hands clasped together uncontrollably, encompassing the figure, and the resulting gust of wind was at least force 10.

In the darkness, a pair of eyes as bright as stars suddenly opened, and surging spiritual energy appeared in the sky like a vast sea of stars.

Hasegawa Izumi braced herself with both hands, suddenly opening her giant palms.

The Otherworld Demon God tried to restore the trees, only to find that they were decaying inch by inch.

"You possess far too much power."

This made Him frown.

I'm sorry to have amazed you.

Hasegawa Izumi smiled.

Who exactly are you?

The unease in the Otherworld Demon God's heart suddenly intensified.

"Who I am?"

"I have chatted and laughed with immortals, and shared wine with gods. I have roamed the virtual world and questioned the mysteries of the universe..."

A look of reminiscence flashed in Hasegawa Izumi's eyes.

Martial artist, pirate, navy, Ninja, Shinigami, magician...

Various images flashed through my mind.

Only...

"The past is dead, like yesterday; the future is like today."

"Everything is now just a thing of the past; I am simply 'me' now."

At this moment, he had attained enlightenment, and his heart had become even clearer.

His realm was elevated once again, Hasegawa Izumi's every move exuded an even more sacred aura, like a banished immortal.

"It's over."

His expression was indifferent as he raised the sword in his hand, compressing the incomparably sharp Sword Qi to its extreme.

Sensing this power, the Otherworld Demon God was greatly alarmed.

"Right now, my combat power is only 6000, while his is at least 10,000!"

Seeing that there was no way to avoid it, He gave up the idea of struggling and let the sword fall.

"You are a powerful being, but you are powerless to change the impending end of this world! When the planes overlap and merge, await my return..."

"Too much nonsense."

Hasegawa Izumi added another horizontal slash, and the demon's body was pierced by a cross-shaped sword mark, splitting into four pieces that crumbled at an even faster speed.

He turned around with his sword on his back, leaving behind a dashing silhouette.

"No need to come. I'll be there to find you soon."

Volume 4: Chapter 63 I am not alone! (The End)

On Sakura Island, the post-war landscape is devastated, and the once vibrant plant world has become a scene of decay.

Hasegawa Izumi looked down, and with a casual wave of her hand, the star-like spiritual energy in the sky transformed into sweet rain that nourished all things, falling from the sky and dripping onto the earth.

In the blink of an eye, everything on the island came back to life, and everything returned to its original state.

Just then, the light in his eyes gradually dimmed, he clutched his chest with his right hand, and his body slowly fell from the sky to the ground.

"Sage!"

"Lord Sage!"

"Club President!"

"Seeker of Truth."

Shouts came from afar.

It turned out that the girls had rushed over after confirming that the battle was over.

"Sage, are you alright?"

Takanashi Rikka looked worried.

The same applies to others.

They were now top-tier Ability User themselves, so they naturally noticed the unusual expression on the boy's face.

"It's nothing, I'm not injured... it's just a little backlash."

Hasegawa Izumi waved to them, indicating that they didn't need to worry, and then offered an explanation.

In battle, in order to reach the same level of power, he was forced to advance beyond his level and seize the power of the future in order to kill his opponent. Otherwise, given his demonic nature, even an avatar would be difficult to destroy.

However, since it was 'borrowed', it naturally needs to be returned.

As a consequence, he will be unable to use his abilities for a period of time.

After the girls were reassured, a Silver-haired Witch lowered her head slightly, but her eyes lit up.

"So, the Club President is currently at his weakest point?"

The battle is over.

But without a doubt, this war will have a transformative impact on the world.

That face was deeply etched into the minds of heads of state from various countries, who all issued orders to regard him as an untouchable figure.

From then on, the Far East Magic Society, once ridiculed as a chuunibyou (delusional) club, became a mysterious organization existing only in legends.

The Hasegawa family.

"Club President, that guy is a monster."

"That ominous feeling far surpassed that of any enemy I had ever encountered before."

"That's the real 'Kami,' a top-tier powerhouse even in a single universe."
