With thunderous roars, the magically defended castle began to crumble. The stone walls, harder than mithril, shattered like styrofoam, and the durable magic wood pillars used for skyscrapers snapped.
“Wow, the snowballs alone are causing the castle to collapse! It’s falling apart like a toy castle!”
“Mii-sama, even in your records, this seems like a masterpiece.”
“Snowballs alone, and you’re breaking down castle walls that held off past heroes and armies…”
Tamamo clapped her hands, and Yamiyo, holding a , began taking photos. Sena had a distant look in her eyes, her smile half-amused. 
It’s a bit embarrassing to be praised so much. Hehehe.
“Em-chan, here, have another one!”
“Thank you, Hoku-chan!”
Thoughtful Hoku-chan handed me a snowball with an excited expression.
So, she threw the snowballs one after another. Pitcher Mii-chan could throw up to 100 balls. So let’s get to work.
The cursed castle, built on vast grounds, was gradually destroyed by Mii-chan’s carpet bombing, becoming unrecognizable.
“Everything except the inner palace has collapsed!”
It seemed like Mii-chan had won the snowball fight. The castle had collapsed, and nearly all the structures behind had turned into rubble.
“However, young lady, it seems the high-level monsters have endured. They are crawling out of the debris.”
Nimue, who had switched to serious mode, cautioned. Emerging from the rubble were giant earth spiders, the familiar , minotaurs, and dragons. 
All of them are level 50 or higher, with some reaching level 70.
Most of the small fry must have been defeated; now, only the large, high-HP enemies remained.
I fired another [Stone Fire] magic, but even when the snowballs hit the enemies, they only flinched slightly, and the damage seemed minimal.
Their numbers were in the thousands, and they were all in hostile mode.
In other words, they were the opponents in my -Fight-.
“I’ll show the power of the Saint.”
Covering both hands and smiling defiantly, I increased my magic power.
“It’s a festival, after all. We should all enjoy it.”
Gray hair swept out in a gust from Mii-chan, and a pure white magic circle spread out from under their feet.
Magic power flowed through the magic circle, and the Holy Light shone brilliantly around.
[Extra Sanctuary]
“Gugyaa.”
“Gii-gii.”
“Gwaa.”
Under the influence of the holy light, the monsters groaned and writhed. It was a modified version of [Sanctuary] that imposed a Level 10 Down, a 20% reduction in all stats, and continuous damage. 
Thanks to System-san version upgrade, they had access to this magic, which could penetrate this world even more effectively.
The specific change was a modification to all magic and skills, greatly expanding their effect ranges. The alchemy skill that had made the ice earlier also received an upgrade, allowing it to affect the entire area.
“And, an addition!”
[Stone Fire Scattering]
I threw a Kinghorn Bear Beef Jerky. It whizzed into the midst of the monsters.
“Hyahyah, hyan-hyan.”
Of course, the Pomeranian didn’t miss it. Dragging Heimdall, who had been taking a break, it rushed excitedly towards the jerky.
“Um, please release this leash from my hand, Laaadddyyyyyy!!!”
I heard some kind of hallucination, but it must have been his imagination. The Pomeranian, who were robbing the suffering monsters of their food, knew that Heimdallr was their target. It bites and scratches at the suffering demons, as if they were food snatchers, and secures the jerky.
With an attitude of “It’s all mine!” it dashed to attack any other monsters that came close, vigorously protecting it. Of course, the initial jerky was left untouched as it hadn’t eaten it yet.
So, when Heimdall tried to be considerate and pick up the jerky, it turned back and attacked him as well.
“Hey, you idiot dog! I’m picking it up for your sake! Seriously! Don’t bite me for real! You’re way too stupid!”
In addition to this heartwarming interaction between Heimdall and the Pomeranian, Papa staggered forward.
“All right, I’ll release my first seal. Tiramisu parfait, answer my will!”
Papa raised the returned Tyrfing high in the air and unleashed the power he had sealed.
“Blow, violent storm! Rain, pour! Thunder, roar! Thunderous Storm!”
[Dark Wave]
With a swift sword swing, papa released a dark wave from the blade, directed at the monsters. Some of the creatures it touched convulsed and fell over with a thud. They had turned into stone and couldn’t move at all.
It was a Petrification magic. It’s one of Mimic’s specialties. It was an extremely troublesome spell.
“Wow, papa, that’s amazing! Using a feint during the incantation and then applying a petrification spell!”
Papa was something else. With sparkling eyes, he clapped his hands.
“Well, I’ve always admired magic. When I was a kid, I used to write the incantations for magics I came up with in my notebook.”
Papa shared his secret while blushing and hiccupping. He had been preparing for this day since he was a child, he had been a genius from childhood!
“Mii-sama? Let’s keep today’s events a secret from father-in-law. When he sobers up No, I think it should remain a secret.”
“Yeah, you’re right! It’s papa’s secret magic. I’ll keep it a secret from mama too.”
“Em-chan, when it comes to your parents, you’re quite blind and affirmative, aren’t you?”
As advised by Yamiyo, let’s keep it a secret. It’s definitely a secret technique. When Mii-chan gets a little older, she’ll ask him about today’s events and ask him to teach her!
With RiR and Papa’s efforts, the vicious monsters were being eliminated. It seemed like it would be okay even if they weren’t here.
“Well then, let’s head out to defeat Taira no Masakado!”
It looks like Mii-chan and the others will take on the boss. She has a feeling that he’s waiting for them in a rage.
