The Six Wings unmanned attack helicopters floated in the air above District 11.
They were similar to the AH-64 Apache and had one "wing" on either side that had guns and missiles equipped on them.
Helicopters were aircrafts that created lift with the rotor on its vertical axis and moved using the angle of that rotor.
Using that definition, the Six Wings did indeed qualify as helicopters.
But with its 2 rocket engines for auxiliary power and its top speed of Mach 2.5, it was a bit of a mystery whether the Six Wings should be called a helicopter or not.
The unmanned attack helicopters used their AI to check the parking garage that had collapsed first and then checked the suspicious figures climbing over Academy City's outer wall a few hundred meters away.
There were about 5000 of them.
After confirming the presence of enemies, their AI brought them to automatic attack mode.
"Damn it, Yamate…!!"
The Six Wings began their attack at about the same time that Saku Tatsuhiko yelled in anger.
With a metallic noise, the wings on either side of the crafts spilt into three. They now truly had "six wings". The thin wings even had joints and moved almost like human arms as they aimed their various weapons.
"Here it comes!!" yelled Teshio Megumi as the roar of the attack helicopters' machine guns began.
It was less like strafing and more like an explosion.
Teshio Megumi leaped behind the station wagon they had used to get there, but it began expanding after receiving fire. It then was devoured by orange light as it exploded. Teshio was blown a few meters by the blast before she landed on the ground and ran to find some more cover.
"!? They're using Flame Crash bullets!?"
The bullets were made of extremely heat resistant metal and had special grooves carved in them so that air friction heated them up to 2500 degrees. When those bullets pierced armor, they would burn away the electrical circuits and the fuel tank inside.
The attack on the mercenaries scaling the outer wall a few hundred meters away had begun.
The group of mercenaries exploded like a giant balloon. Even from a distance, a red spray could be seen. The attack must have had quite a bit of force behind it because even some of the unharmed mercenaries fell down from the outer wall. The helicopters started mowing down the rest starting with the ones that were firing back.
At this rate, they would all be killed.
Teshio Megumi yelled towards Saku Tatsuhiko who was a bit away from her.
"We need to give up on the mercenaries!! Traveling in large numbers while being watched from above is nothing more than being a giant target!!"
"That's 5000 people! Do you know how hard I've worked for this moment!? Do you really think I can let it all go to waste!?"
"They're mistaking this for us having betrayed them. The ones still outside the wall aren't coming anymore. We need to retrieve the ones that fell inside and fall back!!"
"Fucking Yamate…I'm going to kill him!!" said Saku deep in his thick throat.
"Ha ha. I suppose those things had better be this good since they cost 24 billion yen each…" muttered Unabara as he hid in the rubble after having crawled out of the sewer.
It was the result of his own actions, but the scene still sent a chill down his spine.
He could see a few groups shooting anti-aircraft missiles that they were holding up on their shoulders.
However, the Six Wings merely fired something like a softball at the missiles. Iron sand sprayed out from the balls followed by a high-voltage electric current. A "surface" 20 meters in every direction became an area of electric current and the missiles exploded there.
The Six Wings returned fire with a large number of surface attack missiles which enveloped the area in crimson flames.
(Well, it looks like I kept as many mercenaries from getting in as possible…)
Unabara pressed his back against a large piece of concrete and covered his face with his hands. He tore off the talisman of skin made from Yamate, the man whose face he was borrowing, and put Unabara Mitsuki's face back on. In doing so, his physique and voice changed to that of another person's along with his face.
He no longer needed the face of someone from Block.
(The problem now is how to survive this. I'm sure those Six Wings will see me as an enemy, too.)
The Six Wings' objective was to eliminate the mercenaries climbing over the wall.
If he hid until they fell back, the helicopters should leave on their own.
However, the sound of the air being repeatedly sliced brought a pressure to Unabara's heart.
Looking up from behind the rubble, he saw one of the Six Wings moving its sights toward him.
"Looks like it won't be that easy!!"
While yelling, Unabara pulled out his obsidian knife and swung it.
He reflected the light of Venus activating the Spear of Tlahuizcalpantecuhtli and disassembled the Six Wings with his surprise attack.
When they received the report of what happened, the other two Six Wings turned the gun on one of their wings towards Unabara.
They had no problem aiming directly to the side. The wings had joints and could therefore aim at Unabara like a human arm could.
The Spear of Tlahuizcalpantecuhtli could disassemble all kinds of things.
But it could not target multiple objects at once.
"Kh!!"
He tried to hurriedly jump behind cover, but the helicopters were much, much faster.
The attack helicopters he had called in were going to blow him to pieces.
(Is this the end…!?)
Unabara held up the obsidian knife knowing it was hopeless, but something happened before he could do anything else.
He heard a clunk.
It was the sound of a white-haired Level 5 landing on one of the unmanned attack helicopters. He forcibly grabbed the rotor with his hands as it rotated at high speed and stopped its movements. The Six Wings had no way of dealing with this ridiculous action and it fell to the ground and exploded.
"He" casually walked out of the flames.
Unabara Mitsuki finally relaxed.
"Accelerator-san…?"
"I heard about something happening near the outer wall and found this going on when I got here," said Accelerator in a bored voice as he switched his electrode back to normal mode and leaned on his modern cane. "The others had finished up at the External Connection Terminal and I had destroyed the antenna for the satellite, so I thought it was all over. But then control starts crying about intruders at the perimeter or some shit."
"Ha ha. I assume you figured out on your own that they used you."
"I know you didn't call in the Six Wings for no reason. Where's Block?"
"They got away," said Unabara as he wiped sweat from his brow. "I think they managed to gather about 100 of the mercenaries that were coming in from outside."
"From outside… Tch. So that's what the satellite was for. Block, Member, and now mercenaries. What's with all the pieces of shit I'm having to deal with today?"
Accelerator clicked his tongue over all the work he was having to do and continued speaking.
"So you let the intruders in? You really are fucking useless."
"Well, there was originally going to be 5000 of them."
"You still failed either way."
A Six Wings flew through the air as if to cut off his words.
But this time its sights did not turn Unabara's way.
After traversing the area once, the last remaining unmanned helicopter headed back for District 23.
"It looks like the 'clean up' is over."
"They probably didn't like being destroyed by someone on their side," said Unabara while shrugging. "They do cost 25 billion yen each after all."
