Quick Transmigration: Homewrecker System! [BL]

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

The AI sounds that Sakuma had long forgotten finally resounded again in his ear. He thought he would never activate this AI in his lifetime because W41-FU was enough to maintain all the support AI he needed. Because this AI was not suited for support or maintenance, HU5B4N-D0 had only one function, to destroy. 

Sakuma opened the central control inside HU5B4N-D0's body and then fiddled with the setting. He set up the control level to maximum because he couldn't wait any longer. He heard the sound of gunshots, explosions, and falling metal outside. 

Sakuma's body trembled because he was afraid that Amano-San was heavily injured or, even worse, died. 

"I can't wait!" Sakuma hurriedly finished the set and pressed the activate button on his AI. HU5B4N-D0 took a moment to process the new setting and then confirmed it, "Setting has been confirmed, full-frontal assault mode activated." 

HU5B4N-D0's body rearranged automatically, and his body turned into a four-legged turret with an enormous energy cannon as its head. It walked around Sakuma, "Follow me!" 

Sakuma left his room, he witnessed how Amano-San was trying his best to fight all his androids. There were scraps of metal everywhere. It was like a nightmare for Sakuma, who had built all these androids as companionship. Now they were all destroyed.

But this nightmare was not enough compared to Amano-San. He wouldn't be able to continue living if Amano-San was destroyed beyond repair. Sakuma screamed to Yukio, "Amano-San, come here!" 

Yukio saw Sakuma suddenly came, and in front of him, there was a turret that had a giant cannon as its head. Yukio hastily flew towards Sakuma and stayed beside him, "What are you doing here!?" 

"I will not let you fight alone!" Sakuma quickly clenched Yukio's arm and then commanded HU5B4N-D0, "Full power blast!" 

The androids prepared to attack Yukio again, some of them rushed to Yukio and Sakuma's direction. The turret started charging, the androids were getting closer. Right before the closest android reached them, the cannon had been fully charged;

"Fully charged, Full power attack, initiated." HU5B4N-D0 fired a colossal energy beam that blew almost all android in front of them and everything around. 

Yunyu watched as the energy beam blasted everything into oblivion. 

[… I didn't know that Sakuma's AI can do Kamehameha.]

[Pupa: Stop saying that, or we will get in trouble in later days for copyright.]

Sakuma watched as he destroyed almost all his remaining androids that he had painstakingly built in just one attack. Not only he destroyed his androids, but the blast also annihilated the whole lab. He obliterated his safe haven and everything he had with his own hand. 

Yukio protected Sakuma from the scattering debris. He hugged Sakuma tightly, knowing how painful it must be for Sakuma to watch everything falling apart in front of him.

After everything had been destroyed, Yukio finally realized that Sakuma's lab was actually in the outskirt of Neo Yokto. Lush forest surrounded the labs. It was the perfect hiding spot for someone like Sakuma. 

"Sakuma, it's alright, we will rebuild it again," Yukio tried to comfort Sakuma. Which Sakuma only replied with a nod and hugged Yukio even tighter, as if never wanting to let go. 

"Amano-San, are you alright?" 

"I am, thanks to you," Yukio said. "But we need to leave soon. Neo Yokto is in terrible condition."

Sakuma affirmed, he took a transporter and activated it, "HU5B4N-D0, sphere mode." 

The four-legged turret turned back into a sphere, identical to W41-FU, which made Yukio wondered a bit, "HU5B4N-D0?"

Sakuma scratched his cheek in embarrassment, "W—Well, I have two AIs, W41-FU and HU5B4N-D0. W4I-FU functions as support AI that helps me through daily tasks and maintenance. While HU5B4N-D0 is a combat AI, this is one of its modes, turret mode."

"I never thought that I will have to use HU5B4N-D0 for the first time in my life…" Sakuma shifted his gaze at Amano-San, "But to save you, I will do anything."

Yukio was dazed, Sakuma thought that Amano-San was touched by his sincerity. While in fact, he was thinking about the name.

[Husbando and Waifu… for an evil genius like Sakuma, he lacks creativity, especially when naming his creation. Why not call his AIs with a cooler name, like Xavier, Alma, Cyborg, Eve, or something like that.]

[Pupa: You named your cat in your world as 'Cat.']

[What? My cat has a nickname! Her full name is Catherina Von Sugarlight.] 

[Pupa: You just made that name up on the spot, don't you? You simply name her Cat because you can't think of another name.]

[Hehe.]

Sakuma and Yukio, alongside HU5B4N-D0, entered the transporter, and they were teleported immediately to Neo Yokto. The first thing they saw was a pool of blood under their feet. Sakuma gulped. He didn't dare to open his eyes. 

Yukio carried Sakuma and flew up. He wanted to place Sakuma in a safer place, "No, take me with you, I only feel safe when I'm with you," Sakuma plead. Thus, Yukio flew up while carrying Sakuma in his arm. 

They still couldn't pinpoint Mamoru or W41-FU's location, but the most important thing was to save the remaining citizens. Sakuma's army of androids that had arrived in the city far earlier had already fought against Mamoru's rampaging robots. 

It seemed that W41-FU kept its word and dispatched many androids to orchestrated a struggle against the rampaging robots. 

However, his army had been severely outnumbered, and they wouldn't protect the people unless they screamed, "Please protect me, Master Sakuma!"

Thus, the sentence 'Please protect me, Master Sakuma,' echoed across Neo Yokto as if it was a word given by gods to save them from this crazy massacre. 

But Sakuma didn't like this at all. Instead, he was horrified by the amount of destruction he did because of his stupid wish of becoming a hero.

"It's not your fault," Yukio comforted Sakuma, "I know that you never want to hurt the innocent citizen. I know that you mean well."

"No, this is my fault because there was a flaw in W41-FU. I will fix what I've done wrong, I will stop my own creation," Sakuma said, "HU5B4N-D0, Assault mode: Targeted destruction."

"Confirmed, running the system into Assault mode: Targeted destruction," HU5B4N-D0 started rearranging its body again and turned into a drone with four energy cannons attached to the bottom of the drone. 

"Attack all robots that are not under my command," Sakuma ordered.

"Confirmed, initiating targeted attacks to all robots not under the direct order of Master Sakuma," HU5B4N-D0 that was in drone mode flew around Neo Yokto and started shooting every rampaging androids and robots it passed through.
