Chapter 334.1. Tokyo Liberation Battle

Inside Tokyo, which was being purified by Mii-chan’s illusion magic, there was a special unit infiltrating while the adventurers were out gathering magic stones.
“Initiate the attack! It’s time to reclaim Tokyo!”
“Yeah!”
[Fireball]
[Earth Spear]
[Wind Blade]
Various types of magic spells were flying through the air. The monsters, which were too damaged to even walk, were blown away and defeated.
The Tokyo Liberation Battle, also known as the Snow Festival, was now in full swing.
“The enemy no longer has any strength! We will settle this here!”
The one leading the charge with high spirits was Uncle Ouga. Despite being quite drunk, he was effectively commanding the Warriors who had joined the Snow Festival. Quite impressive mental fortitude, I must say. That alcohol was supposed to have an effect for just a day, but oh well.
“Bonuses are rolling in! Stick a stick in an eggplant for a bonus.”
Perhaps his mental fortitude wasn’t that strong after all. It’s a sad reality that the cool, silent old man also turns into the “usual” old man when he gets too drunk.
“This is a piece of cake!”
“So this is what they mean by ‘kill two birds with one stone’.”
“Go, the magic sword T… something!”
Papa and the others were also doing their part. They were casting magic spells and using magic tools at will, and the magic sword Tyrfing was soaring through the sky, attacking the relatively stronger enemies among the ranks, which was quite reassuring.
“Papa is so cool!”
“That’s right! Occasionally, papa has to show his cool side. There, Tyrfing-something!”
Papa was skillfully manipulating the high-speed flying magic sword Tyrfing! Tyrfing circled the sky like a tornado, cutting down the enemies. Papa waved to Mii-chan as he did. In the meantime, Tyrfing kept taking down the enemies, so it seemed that papa had completely mastered and controlled it.
“Still, I didn’t think high-level monsters would be on the brink of death with just a little damage. It’s pathetic!”
“Normally, they’d keep attacking even with just 1 HP left, Em-chan.”
In the games’ world, monsters would attack at full power even with 1 HP remaining. However, in this world, the monsters seemed to stagger and nearly die just from a little scorching. 
Level 30 monsters should be strong enough to be formidable opponents for the people in this world, but they could barely move, let alone fight.
So Mii-chan and her group advanced swiftly. Until now, the overgrown cursed forest had served as a natural dungeon, hindering their progress. But once the cursed trees disappeared, the land was cleared, making it much easier to advance.
We had vehicles for their advance, cutting into the heart of Tokyo would have been a breeze.
As they defeated the monsters and advanced, the adventurers with a keen eye quietly collected the remains of the high-level monsters that had been left behind. It goes without saying that Kongou-oneesan were also among the adventurers with keen eyes.
Trampling over the remaining Holy Ice, Mi-chan and her party arrived at Taira no Masakado’s castle almost effortlessly.
The castle emitted an eerie and ominous dark aura, like a cursed castle resembling a Demon Lord’s castle, with black clouds looming over it.
Entering this area alone would result in damage from the contaminated air filled with miasma. On the other hand, there were monsters empowered by the miasma, as well as deadly traps like poison gas and collapsed passages, turning it into an impregnable fortress.
Or rather, it had become so. It’s now in the past tense.
“Wow, those pure white particles floating in the air, it feels so refreshing with their holy power, Mii-chan.”
“It’s like sprinkling sugar on the black castle; it looks delicious!”
“It’s already falling apart! The walls are melting!”
Sena took a deep breath, and her eyes sparkled. Nan-chan likened it to sweets, and Hoku-chan was impressed.
“The castle itself was cursed, so this trick was fatal, it seems.”
It had become a cursed castle in the style of Taira no Masakado, on the verge of becoming a dilapidated house. The gate was leaning, the walls were melting, and it was on the brink of collapsing.
However, thanks to a powerful curse, it was still standing, emitting a sizzling smoke that resembled being doused in sulfuric acid. The aura of evil clung lightly to the building, suppressing the damage.
The building was slightly covered with a miasma-infested disastrous aura that tried to push back the Holy Ice, holding back the damage.
Unfortunately, the air within the Demon Lord’s castle was no longer pure and refreshing under the blue sky.
But that’s how it goes; it’s a hidden dungeon. Holy Ice alone might not be enough to bring it down.
“So, are we going to infiltrate the castle?”
Yamiyo, who had changed into a pitch-black magic armor, asked with a resolute expression. She was already brimming with enthusiasm.
Tamamo and the others had also donned magic armor and were equally eager. There was one girl equipped not with magical armor but with a kotatsu, though.
“Well, first, we need to reduce the enemy’s defense to zero. There are lots of deadly traps in the dungeon, you know!”
“So, should we attack from a distance?”
“Yeah, there are so many throwing items scattered around. We can’t afford not to use them.”
She scooped up some snow, rolled it into a ball, and placed it on the ground. As everyone watched, they rolled the snowball. It quickly grew to be as big as Mii-chan.
With a cheerful smile, I lifted the snowball, a weight they could manage.
“Ta-da! I made a snowball nicely!”
It was more like an ice ball. Using it in a snowball fight would undoubtedly lead to some serious complaints.
“Well then, let’s start the snowball fight!”
-Fight-
[Stone Fire Scattering]
I raised the snowball high for their first throw, charging it with magic power. 
Mii-chan’s snowball flew like a missile toward the castle at breakneck speed. In mid-air, the snowball split into dozens of smaller ones and rained down like a carpet bombing, hitting the castle one after another.
