Having his divine core severed by the Olympian Sword,
At this moment, Zeus no longer had any power to resist. Reduced to a mortal, he could no longer use his authorities, and he reverted from his Lightning Giant form back to his original state.
Then...
Kaito flew into the air and watched as the tip of the Holy Spear, Rhongomyniad, precisely pierced the location of Zeus's heart, then plunged into the earth along with him.
The ground began to undergo violent earthquakes, the entire Netherworld nearing a state of collapse.
At that very moment, Aisha appeared again, reached out to grab Kaito's hand, and led him into the Fairy's Corridor.
At that same moment, the Netherworld began to shatter, and the humans of that world entered their doomsday twilight, everyone dying within the crumbling world.
However, Kaito did not show them any mercy because of this.
He had said it before—if he was going to destroy this world, then he would follow through.
Besides, all the humans in this world only believed in Zeus, and given Zeus's own degenerate nature, the humans who believed in him were actually quite chaotic themselves.
At the very least, Kaito could tell from the humans in the houses at the foot of the mountain.
Their civilization wasn't high, but the chaos was real...
As for what kind of chaos, those who know, know.
"Congratulations!!!"
Pandora appeared happily in front of Kaito, bouncing up and down with a joyful expression.
"Oh? Finally decided to show yourself?"
"Mm-hmm~"
Pandora's cute lips curled up, she put her hands on her hips, straightened her back, and preened proudly for a moment.
"Well, I've killed Zeus this time, and I'm planning to kill Odin next. Is there anything you can do to help?"
"Odin?"
"Yeah, what's wrong? You think I can't kill him?"
"...Not right now. You'll need to wait a few months, until after 'that person' appears."
Kaito narrowed his eyes slightly. He guessed that 'that person' probably referred to the King Who Manifests at the World's End from the original work who intended to kill all the Demon Kings.
Kaito was actually quite interested in him; when he first read the novel, with all that talk about the Last Steel and such, he even mistakenly thought he was King Arthur!
"A few months, huh... Looks like I'll have to deal with that later. What about the Eastern Tathagata?"
"Tathagata? That... doesn't seem very feasible either. He's stronger than Zeus, and resides in an even more powerful Netherworld. There's no way to enter through normal means, and that guy's a total shut-in! Just holed up in there!"
That's what Pandora said. Kaito was stunned for a moment upon hearing this, then couldn't help but burst out laughing.
'Are you just messing with me?'
Having only killed Zeus, how could that possibly satisfy him!
His initial idea was to boost his strength all the way to the SSS-class level in one go!
"So, what about that God of the Bible?"
"Hahahaha! He died long ago, and is currently sleeping."
Pandora couldn't help but want to laugh too. For some reason, she suddenly found watching Kaito get frustrated amusing, seeing him with that kind of desire he couldn't fulfill.
Despite his strength being sufficient to kill them, he just couldn't.
"...Alright, I give up."
Of the Four Heavenly Kings of the Mythological Realm, only Zeus was killed. The remaining three were unkillable, and Kaito felt helpless.
What?
Where did the Jade Emperor go?
No, isn't it common sense that the Four Heavenly Kings are actually five people?
He's not going to kill the Jade Emperor anyway!
"Oh, wait a moment!"
"...Hehehe~ Regarding your complete slaying of Zeus, using his own weapon to sever even his divine core so he can never exist again, I now have one piece of bad news and one piece of good news. Which do you want to hear first?"
Suddenly remembering something, Pandora vanished on the spot. After a while, she returned holding a very ornate treasure box in her palm. Instead of directly giving it to Kaito, she let him choose.
"...I'll hear the bad news first!"
'Could something be wrong?'
Kaito's heart trembled.
He instinctively thought that since he killed Zeus in a way that prevents resurrection, does that mean he won't even get to draw his Authorities?
If that were the case, he'd be so angry!
He put in all that effort to kill him, only to end up with nothing!!
"The bad news is... because the Divine Core was erased by you, the Authorities Zeus possessed are gone. Well, since Zeus can't be resurrected either, it's only natural they disappeared along with him."
Pandora said this with a 'very serious' expression. Hearing this, Kaito inwardly sighed, his heart beginning to bleed.
'No, wait, what about the good news!?'
"Then what's the good news!"
"The good news is... Hehehe, ta-da~!"
She handed the treasure box to Kaito, indicating for him to open it. Inside was the so-called good news!
"This... don't tell me it's Pandora's Box?"
"Oh? How did you know?"
"..."
'Damn, I was just asking casually!'
Kaito was rendered speechless, but since Pandora gave him the box and told him to open it, maybe there was something inside that would make him happy.
At the very least... it wouldn't be something that left him empty-handed, right?
Click—!
"!!!"
"Th-This is!!"
The box opened, and the entire white space was instantly filled with lightning!
Seeing the joy of regaining what he thought was lost on Kaito's face, Pandora felt happy too, striking a pose that said 'I'm so awesome', then continued resting her hands on her hips for a while, letting Kaito remain amazed.
"These... you managed to intercept all of these, right?"
"That's right! Although these would have dissipated along with Zeus's death, I just needed to grab them before they vanished. But my box can't hold too much, so I picked the most important ones."
"I see... so your Pandora's Box has this kind of function..."
"I can even store things like calamities, so why not other things?"
Pandora retorted, and Kaito couldn't help but laugh loudly, happily hugging Pandora with one arm.
This was great!
His efforts hadn't been in vain!
"O-Okay! Let go of me quickly! I am your 'mother,' you know!"
"Isn't that even better?"
"???"
'Wait, something's wrong with you!'
'What do you mean, 'isn't that even better'!?'
Well, Kaito was too happy to care about that right now.
After all, this reward was far richer than what he would have gotten from a normal godslaying!!
"Pandora, would you be willing to leave this world with me in the future and travel around other worlds?"
"I am not willing."
"Hah, you might not have a choice in that. But I can't do it just yet; eventually, though, it will happen."
