Quick Transmigration: Homewrecker System!

BANG!

Yukio tried to shoot W41-FU with a bullet, but W41-FU already activated its shield, and the bullet was deflected before it reached W41-FU's body. 

"What are you doing?!" Sakuma tried to stop Amano-San from shooting his creation, but Amano-San did not budge.

"There is no point negotiating with that thing already! It clearly doesn't want to obey your command anymore. It has independent thoughts!" Yukio shouted as he gunned down W41-FU a few times. But W41-FU's shield protected itself from any harm, at least temporarily. 

"Activating self-defense system, integrating…" W41-FU didn't want its body to get destroyed. Thus it controlled upon one female android inside the lab and integrated itself into the female android body. 

W41-FU's spherical body replaced the female android's head, acted as the new head and controller of the female android, "Operation Assault on Yukio Amano."

W41-FU transformed its hand into a drill machine and charged towards Yukio with killing intent. Yukio pushed Sakuma to the side, and he barely dodged the drill attack by an inch. Yukio replaced his hand with the same drill machine and attacked W41-FU. 

W41-FU was not suited for combat. It was more of a support assistant and commander. Thus, it didn't have enough agility to dodge the attack, and its stomach was drilled and destroyed in the process. 

Sakuma was distressed when he saw the destroyed body of a female android he created with his own hands. He was also distressed because his most loyal support assistant AI, W41-FU, turned against his back, "A—Amano-San, I can perhaps tune W41-FU back to normal. There must be a bug or a virus…"

"Sakuma! Look in the monitor! Don't you see how much damage this thing did to innocent people?!" Yukio yelled. Sakuma glanced at the monitor. There were rivers of blood everywhere, humans got gored or decapitated by machines, and Mamoru was standing as the commander of all androids. 

"I…" Sakuma was still trying to digest the emotional burden put into him, but W41-FU didn't wait. It instantly called upon another android and attached itself as the new head, just like the previous one. 

W41-FU attacked Yukio again, now with high powered energy blaster. W41-FU charged the high powered energy blaster, intending to destroy the whole room, so Yukio couldn't dodge anymore. 

"Damn it!" Yukio heated his leg, and then he dashed quickly to save Sakuma first. He carried Sakuma and dashed out from the monitoring room. In only a few seconds, the monitoring room exploded from the inside and destroyed everything in the process, exposing the laboratory to the outside world. 

Sakuma was surprised that he finally saw the sky directly for the first time in eight years. He saw the sky was cloudy as it was already autumn season. Sakuma felt exposed and scared as his trauma eight years ago surged up. He clenched Yukio's shirt, "Amano-San, don't leave me. I am… scared."

"I will always be by your side!" Yukio comforted. But he couldn't comfort Sakuma for too long because W41-FU already charged another high powered beam at them.

"Wait here," Yukio said. But Sakuma clenched his shirt even tighter. His body was trembling all over, "Don't leave me! I'm scared!" 

Yukio saw the fear in Sakuma's eyes. It was apparent that he was scared after being exposed out of his shell. Yukio gritted his teeth and then hold Sakuma with one hand, while his other hand had the fingers turned into a long rod induced with electricity. 

"Hold tight!" Yukio said to Sakuma. Yukio dashed quickly before W41-FU fully charged another high powered beam, and he stabbed the neck of the female android that attached W41-FU to its current body.

Yukio discharged a massive amount of electric current on his long rod and electrocuted W41-FU in the process. The female android body exploded on the spot, but W41-FU was still unscathed, albeit losing its ability to attach itself to an android now. 

W41-FU knew that its chance to win against a perfect android like Yukio Amano was slim. Thus it flew away to the open air and escaped. 

"Operating command: restrain," W41-FU made another command, and many inactive androids in the lab that hadn't been dispatched to fight against Mamoru in Neo Yokto had been remotely activated by W41-FU. 

Their eyes glowed red. They pointed their various weapons at their creator, Sakuma Hoshino, but Yukio and Sakuma knew that Yukio Amano was the real target. Sakuma was afraid that Amano-San wouldn't be able to fight all of them. Though he was a perfect android, it was too risky. 

Sakuma gulped, his body was still trembling after being exposed to the open air, but he braced himself and said, "Amano-San, put me down. I will shield you first. So you can chase my AI. These androids will not attack me."

"And leave you alone here?" Yukio had his eyes on the androids who were ready to attack whenever he tried to escape. 

[Where does that evil AI went to?]

[Pupa: It went to Neo Yokto to assist Mamoru on the task, sensing that you might be able to beat Mamoru before the malfunctioning androids under Mamoru's command killed at least half of the population in Neo Yokto.]

[I see…]

Yunyu watched Sakuma's trembling body, his breath was heavy, but he tried to brace himself to face the hostile androids he had created. 

[Sakuma must be heartbroken. These androids are his companion for eight years. I don't want to leave him alone in this exposed, heartbroken state.]

[Pupa: You still have time, W41-FU is a command-type AI. It doesn't have an extreme speed to reach Neo Yokto without a teleporter.]

Yukio finally decided what he should do, he put Sakuma down, but he also said, "I will not leave you alone, I will never leave you alone!" 

Yukio prepared himself, and he transformed his left hand into a sword and his right hand into a machine gun. He screamed out loud and charged towards hundreds of androids. 

Sakuma was dazed as he watched Amano-San fought against his androids courageously. Although the chance was slim, they still had the opportunity. Amano-San's courage influenced Sakuma because he didn't want to watch Amano-San's body getting destroyed, he stood up from the floor, and he ran towards his bedroom. 

He entered his bedroom, took a book from the antique bookcase, and opened the middle page. There was a card key protected with a password inside. He typed the password and took out the key. 

Sakuma rushed to a safe near his bed and used the card key.

Once the safe had been opened, there was a sphere-shaped android, identical to W41-FU. Sakuma took it out and activated it. The sphere eyes glowed green, and a welcome message was heard;

"HU5B4N-D0 has been activated. Greetings, Master."
