I--the wizard, Nevis, was leading his troops on the battlefield.
　It was a siege under Sharon's senior's curtain, alongside the golem army.

　The target is a strategic stronghold of one of the Black Witches, the "Knockers of the Otherworld" (Keosnockers).
　It is an impregnable fortress surrounded by high and solid outer walls.
　Moreover, it is protected by an army of "outers," or unworldly chaos, summoned from the other world by one of the most powerful witches in Vivera hara, which makes it almost impossible to topple.

　And yet, our Strategist Magnus, not to mention Henri Magnussaud, is proud to say that he will bring it down.
　I'd like to see what he's got in store for me, but he has given me a role to play.
　First of all, let's do it.

"Gentlemen of the Magical Fire Support Unit under the direct control of the Military Master!　Are you ready?

　I shouted out loudly out of character and gave a command to the wizards under my squad.

　The placement of our magical firepower support unit is at the rear of the golem army.
　More than a thousand golems lined up in a row on either side of the castle wall, parallel to the wall.
　Protected behind them, we all chanted spells at once.
　It was a plan to strike the walls with the offensive magic that each of us was good at, and if we could destroy them, we would get lucky.
　Of course, the idea was conceived by Henri Magnussaud-dono.

Now, I doubt that it will work.

　Before going into battle, after listening to the military master's explanation of the strategy, the one who raised my suspicions was a loathsome little girl named Isabella.

"That fort's walls and gates have been properly treated for magic resistance!

　And Zucci or some shitty, cocky little b*tc* called Zucci agreed with me.

　I knew that even if they didn't say that.
　Henri Magna - that's a pain in the ass, I'm sure even Lord Magnus would be.
　If the walls of the Witch's Country were just built with a mere pile of stones, they would be quickly shattered by attack magic.
　The concept of a group firepower operation was first put into practice by Pauli-sama at the Pirate Trading Company, but a single Sharon senior's Fire III would be enough to break through the gates of the city.
　There's no reason why they don't have that countermeasure in place.

''Ah, I think even Henri-sama knows about this strategy, and I'm sure he knows about it~''

　And while whispering, the only person who held Magnus-dono's shoulder was a little girl named Kate or something.
　And Sharon-senpai, who approved of the operation.

　Of course, Magnus-dono's plan was to go beyond that, based on everything.
　The strategy was that each of us would hit the city walls with our signature attack magic and if we could destroy it, we would be lucky - in other words, the strategy was that we didn't need to be able to destroy it.
　The role of our magic firepower support unit in this battle is - a diversion.
　You're also making a lot of noise by hurling flashy attack magic at the city walls.
　Even so, they are still unable to destroy it, and are pretending to be laborious.
　Everything is a decoy for the main mission.

　　　　◇◆◇◆◇

　I - the wizard Magnus - was carrying out an infiltration operation.
　Every castle and fort has its own secret loopholes.
　They are underground passages that allow only those in power to safely escape from the castle when the need arises.
　Throughout the ages, their ways of thinking have been similar to each other to the point of shallowness.

　And now we've used that underground passage to break into the fort.
If you read the strategy book, there are no secrets or shit, and it was obvious where it was.

　You will be able to find out what is going on in the world.
　Gladius leads the way, followed by me and Chocolat.
　I'm not going to be able to get a good idea of what to expect.

　On the way, there were glimpses of outerers guarding the passage.
　As residents of another world, these people can only be summoned by witches with a unique talent.
　That's why there are few reports of their discovery, and there is no literature left on them, nor are they named or classified.
Even the guidebooks have information on their level and status, but their names are simply marked with characters that look like worm tracks.

　A monster that looks like a breathing silver disc.
　A monster that looks like an octopus with no head.
　There is a monster that is hard to describe, which makes you go insane just by looking at it.

　Such "unworldly and chaotic things" have been in this passage for decades, and they stand in front of us.
　I defeated them with Gradius' rigid fist and my Manabolt IV, while hurrying onward.

"He who knocks on the gates of the other world (Keosnocker) probably didn't expect to be taken in the opposite direction of this secret passage.
　The outers that are deployed also have a strong sense of minimum security, and we were able to break through without difficulty.
　We opened a hidden door and arrived at the basement storeroom of the fort.

　Now - there are two strategies we can adopt from here.
　Do we open the gates from the inside and guide the golem army?
　Or we could go directly to the otherworldly gate knockinger inside the castle.

　What would a true master strategist do?
　I'm sorry, but I'm going to have to do it the hard way.

According to the information in the attack book, the area around the gates is always teeming with Outers.
　On the other hand, the "knocking on the gates of the other world" (Keosnocker) secretly despises the Outers and rarely has them around.

　In other words, it is best to go and attack "Keosnocker" directly.
　The structure of the inside of the fort is also perfectly understood thanks to the 'strategy book'.

　I'm sure you'll be able to find out more about this as well.
　They look creepy and their ecology is unknown, but if you convert them to levels, they're just 15 stop monsters at best.
　The unknown is frightening to everyone, but the known is not to be feared.
It's a stark reminder of how reliable the Libraries are.

　And you'll make it to the top floor.

"Who are you!　How did you get here!

"The witch Lianlar, aka 'Keosnocker', the one who knocks on the gates of the other world, questioned us angrily when she saw us.

　Her face is a bewitching beauty of about 30 years old.
　However, her dress-clad body was unnaturally puffy from the inside out here and there.
"It seems that the price of summoning the unworldly chaos is that her body has become slightly on the other side of the world, distorted and with countless breasts all over her body....

''You crooked bastard!　Come on!　Meet me!

　Leanne Rahrer called the outers together in disgust.
　To bring her trump card, the most powerful monsters, to bear on us...
