We searched the surrounding for a while, but we still couldn't find Sofia-san and used Local Wife to warp to Empress Brigade's headquarters.
I planned to notify them of Sofia-san's plan to destroy the dungeon city and used the brigade members to search for Sofia-san's location with human wave tactic.
The Lion King also came to the Empress brigade's headquarters for arranging the brigade alliance, so I told her about Battle Princess Sofia-san's story and asked her to search for her whereabouts.
「I see now...so the Battle Princess is a vengeful demon created by this city's distortion.」
「Well, it can't be helped even if this good-for-nothing city become a target for such revenge. But even so, we're also not soft-hearted people who'll just let ourselves got destroyed one-sidedly. Sorry but we'll deal with her before she can carry out her plan.」
The Lion King and Empress Stacy-san said that and ordered their brigade members to gather information of Battle Princess Brigade.
They were taking action quickly in order to find Sofia-san as fast as possible.
Their action must be because of how much they were wary toward Sofia-san rather than them believing my words.
「Well, there's no need to be that worried though.」
The leopard beastman Liza-san who was listening to my story together with Stacy-san and others said that while laughing off the situation.
「No matter how strong that Battle Princess is, it's impossible for her to destroy this big city. It might be a different story if she has expanded her organization lots, but the current Battle Princess Brigade has just gone through infighting yeah? Even if her plan is to slowly eliminate us the top brass of opposing brigades, the capital will just notice how the three great brigades are weakening and holy knights will come from there to rule this city next. Destroying the city is just a dream within a dream.」
「Well, certainly it's like that...」
What Liza-san said wasn't wrong at the slightest.
Sofia-san's words of wanting to destroy the city normally would only sound like an exaggeration due to her getting ahead of herself because of her wish for revenge.
「But I have this bad premonition for some reason. I really can't imagine that Sofia-san's words are just nonsense...I think we shouldn't let our guard down.」
「Even if you say that」
Liza-san scratched her leopard ears hearing my words.
「If you want to destroy this big city, it'll be impossible unless you got an army or monster swarm of hundreds of thousands suddenly showing up out of nowhere. You'll only get the carpet pulled from under your feet if you're keeping your guard up against that kinda unrealistic――」
...Before Liza-san could finish saying her sentence.
.
────────────*DOO-!!*
.
An extraordinary shaking assaulted the dungeon city.
「What!?」
A tremendous tremor was making the whole building creaking.
Furthermore far from settling down, that shaking was gradually getting stronger and there was even thunderous sound of something crumbling reaching our ears.
In addition there was even the sensation of abnormal amount of mana bursting up from the bottom of earth――all of us were rushing out of the room together.
Alicia, Stacy-san, Liza-san, Lion King, and me were heading in a straight line toward the highest spire inside the Empress Brigade's headquarters. On top of its rooftop.
From there we looked down on the dungeon city and I doubted my own eyes.
「The dungeon is...collapsing...!?」
The entrance into the dungeon that was located at the center of the city.
There was a large collapse there and you could peer into a huge abyss from there.
The abnormality wasn't just that.
There were collapses all over the city, forming many large holes.
Boiling up from the large holes that suddenly appeared were torrents of mana with thickness that surpassed human knowledge.
Jumping out from each hole after that were――large amount of monsters.
「This is...dungeon collapse!?」
「Impossible...! A gigantic dungeon that has gone through many years since it appeared breaking down like this...don't tell me it's artificial!? No, that's even more impossible...!?」
Stacy-san and Lion King were speaking out with astonished tone.
My head was also turning blank seeing the nightmarish sight.
But,
「...Tsu! We need to stop it! Before the damage spread out! As much as possible!」
What flashed at the back of my mind was the smile of Sofia-san when eating happily together with us.
I broke into a run faster than anyone toward the monsters that were spreading through the city.
＊
The shaken dungeon city.
A werewolf girl was smiling inside a dilapidated building at a corner of that city.
The beautiful swordswoman armed with two short swords was the Battle Princess Sofia.
「...Dungeon collapse...a disaster that occur when a dungeon that is producing monster due to the influence of mana inclination has its mana's balance greatly disturbed. Monster will overflow endlessly from the breaking dungeon...inflicting damage to the surrounding.」
Sofia continued speaking in joy as though she was singing.
「...But, a dungeon so huge that people would built a city around it is stable despite its immense mana inclination. It'll scarcely break down. But actually...there's a brute force way to destroy that equilibrium...」
What Sofia's hand was holding as she said that was a magic stone that was made from compressed mana. Furthermore it was a high class one with very high purity.
「...If magic stone is crushed in a particular way...it will give rise to a violent explosion of mana. If this magic stone is gathered and gathered in the deep level near the dungeon core, gathered until an amount that can buy a small country...and then remotely detonated, the dungeon will break...just like I was taught...」
As expected when the dungeon was this gigantic, it wouldn't completely break just from an artificial outbreak acceleration. One day the dungeon would get repaired naturally.
But even so...the number of monster overflowing from the dungeon until it got repaired would be more than enough to destroy the city.
「...hehe, eheheheheh. It was worth it using my presence isolation unique skill to avoid monster...and steadily brought magic stones deep inside the dungeon...!」
Sofia made a gruesome smile.
Beside her was a man past middle age crumbling on his knees with a paling expression.
「U-unbelievable...this damn brat, really done it...!」
He was an executive staff in the Battle Princess Brigade who had been managing the clerical work ever since the brigade was still called Bloody Princess Brigade.
That man had been kept alive until now to procure the magic stones that the Battle Princess hadn't managed to obtain as well as keeping the brigade running until now. He looked up to Sofia and spoke with trembling voice.
「How...! How the hell! You were a slave just for the Bloody Princess-sama to toy as she pleased! The Gift you obtained was also just a mediocre one! You didn't even have anything like unique skill, you were just a feeble brat! And yet how did you become this kinda monste...!?」
The man couldn't finish his yelling.
He got chopped apart by the Battle Princess in an instant and fell down on the spot.
The Battle Princess flicked away the blood on her short swords, as though to say that her business with this man who was exploiting the weak together with the Bloody Princess was finished.
「...This city is already a monster nest...what's left to do is just watching the situation for a while, then eliminating the exhausted main forces of Lion King Brigade and Empress Brigade in the middle of the chaotic battle...and then, this city will vanish from the map with other countries not even having any chance to interfere...」
It was simple.
Now, let's quickly erase this good-for-nothing city.
Battle Princess Sofia went outside the dilapidated building with a bright expression.
It was then.
「Eh...?」
Suddenly the faces of a soft-hearted young man and a girl who seemed to have strong lust flashed at the back of the mind of the girl who was possessed by revenge.
It was the happy memory from just now when she walked around the city with her first friends.
Instantly, a weak voice slipped out from Battle Princess Sofia's mouth.
.
「Did I really, want to slaughter everyone...?」
.
A strong doubt burst out inside her.
However at the next moment.
「...tsu!!」
The Battle Princess's heart was covered with pitch black darkness. At the same time her body also got wrapped in a darkness that was like thick mist.
『Kill everyone』
The voice of the woman who gave the Battle Princess her strength echoed.
Several seconds later, any hesitation vanished from the Battle Princess's face.
「...Yeah. For now, let's think after killing everyone...」
Without even noticing the tear that was spilling out from her eye――.
.
The Battle Princess started walking toward the massacre.
Stacy: And? What's your business?
Liza: You went out of your way calling us to this kinda inn. It must be something no good again...
Alicia: No such thing...just, I'm thinking to show appreciation to you two after being a bit unreasonable with many things until now.
Alicia: I've ordered foods that I personally chose from many restaurants...eat a lot for energy――
Alicia: (...Thinking carefully, it might be a bit wrong to secretly give them horniness doping like this)
Alicia: (The purpose of the plan this time is to have these two get along with Erio by their own initiative as much as possible...having them eat vitalizing foods beforehand is...going against the aim)
Alicia: (Besides...even without something like this, if it's Erio who's the most charming in the world...these two will obviously fall with just his plain self...)
Alicia: ...Yep. As expected let's stop. You two can eat the foods in the middle of getting along...for now just wear these lewd underwear and wait on the bed.
Stacy: Ha!? Wai-, what do you mean by showing appreciation!? You aren't making se――kuh, my body's moving on its own!?
Liza: O-oi!? Just what the hell are you trying to do huh!? Wai-, you're serious with this underwear!? Oi where're you going! Don't just leave us dressed like this damn you!
Alicia: ...It's fine. I really want to show my appreciation. ...But, it'll be better if you two can be a little more honest.
Alicia: ...Then, look forward to it…
