"The town you're going to attack this time, Crust, is a fortress of iron walls surrounded by a 30m outer wall with a 200m high and low difference cliff on the back. It's a town like a fort in charge of defense from a country called Magi of neighboring countries or something, and it's said to be one of the best fortresses in Boreas. Well, the rumor is, they've never actually been attacked, so they have all sorts of callings, for better or worse."

Former Cor parent's troop leader Argus explains the situation as he puts his finger on the expanded map and aerial photos. At the tip of his finger like that, the appearance of a fortification-like town built on a large ripped cliff had spread. That seems to be the castle city Crust in southeast Boreas, which is the target of this attack.

"What kind of name does it have?

"Deputy Sylvia. You can't ask Yuki or Nuru that more than I do. I don't want to upset you two by saying bad things."

and when Argus speaks, Null, who knows the circumstances, starts talking.

"What, I don't care if you keep telling me.... an unbeatable town, a false fortress, an economic city in difficulty. Well, for better or worse, there are various callings. As a" fort, "I've never been able to make a difference before, but as a relay point for a deal with neighboring Magistasia? Tax revenues are the second largest of all towns, after the city of Vixen. But... I don't think the day will come to drop my own crust."

"By the way, from Master Null's point of view, do you think that town is easy to attack? Do you find it hard to attack?

"Huh... that's a stupid question!

"... Sister Null. I don't know which that is then." It's very difficult. "

So Yuki bitterly complains about Null's vague statement. Apparently, not a glimmer, is the conclusion of the Yuki and Sirius sisters.

Argus asks against those two.

"Is there any good way to drop the town of Crust? Like this, there's a hidden passage to get inside the town, there's a brittle part on the outer wall..."

"There are no hidden passages. Magistasia is, to say the least, the land of the witches. If you make something like that, you'll be immediately detected and entered, so make something like that... no, it's not there. But you think it's easier to attack normally? Even if you say there's a way in, it's in the middle of a cliff, and you're only supposed to leave."

"Even the witches made it because they thought they would never bother to go around the back of town and find a passageway hidden from the wall."

"And there's no brittle part of the wall. I mean, shouldn't we blow it up with shelling from the energy? You think you can crush it with a single blow?

"No, I'm too powerful to have a dead man.... you have no choice. Do you want to plant a plastic bomb and blow it up?"

and Argus, who begin to set up operations that are vastly out of this world's technical standards. Their aim was not to destroy the town, nor to kill those living in it, but simply to expel the Ecclesiaans... It seems that all those who were on the spot were averse to the siege with great power.

In the meantime--,

"Um..."

—— Amber opens his mouth only with his face out from the top of the carriage, looking around with glue as he sat in a rotating chair, wary of Eccleria's airship flying.

"If you remove the outer wall with metastatic magic, can't you?

"No, no, Master Amber. If you can do that, there's no point in building walls in cities, is there?

"Exactly. She may be able to do it around Lucia, but she has been told by Master Waltz that she is in this fight."

"It's the mountain of Sekiyama that moves one tank, even with the line of transfer wizards. The outer walls are very, very..."

and everyone, in showing difficulty in Amber's suggestion, only Yuki--,

"... oh, I see!

--I think I got a convincing look on my face. She knew Amber was a transfer wizard who wasn't "lined up". By the way, the wise man should have known it by nature, but he doesn't seem to remember it because he's losing his memory.

And the next morning. At the head of the soldiers, who felt somewhat less gessy than yesterday, were the witch Amber and the witch Sophia.

"... I've told you there's never going to be an attack, but you don't know how life will fall, do you?

"What?"

"No. Talk to yourself."

With that said, Sophia turns her narrow gaze toward the town of Crust, which looks beyond the horizon, whilst wearing a black robe. To her remarks like that, Amber seemed to be leaning her neck, but seemed to have no further pursuit of the situation, perceiving that Sophia would not try to open her mouth any further.

"Well. Shall we begin? Well, it's not me who does it, it's Amber."

"I'm getting nervous..."

"Nothing to be nervous about? Amber's back is protected by me, so keep exercising your metamorphosis magic without worrying about Lucia's beam flying as the tank shells fly. Partner (My Buddy)"

…………

Amber, inspired by Sophia, takes a deep breath--,

"... I'll take care of it, okay? My back."

—— with both of those hands toward the town of Crust --,

Bun......

—— began to exercise metastatic magic.
