Crossover Anime: I Became Invincible Starting as an Ajin

The research institute is, after all, a research institution, even if it has been militarized in response to the Sato attack.

However, it still exposed the weakness in military force.

Even though the weapons have been modified to target demi-humans, the soldiers' training and simulations are still based on normal people.

The current actions against the demi-humans are truly beyond what is expected.

On the rooftop, Wang Bai and the other two had already spotted Nagai Kei and his escort team.

Kei Nagai was presumably under anesthesia and remained motionless inside the sealed restraint bag.

Before the three of them could speak, the escort team members knelt on the ground, put down their weapons, and raised their hands in surrender.

The combat information transmitted through the voice system fully demonstrated the terrifying combat power of these demi-humans.

The main force had been wiped out, leaving only their small squad. They hadn't even seen a helicopter, so they were practically trapped on the rooftop.

The money they earn in a month is not enough to make them risk their lives right now.

However, to the squad's surprise, a bullet struck one of the soldiers directly in the head.

Wang Bai was stunned, then realized what was happening and looked in Sato's direction.

Tanaka looked on incredulously: "Why? They clearly surrendered!"

Sato explained simply, "The other party is making some subtle moves. Also, be careful, the other party has attacked."

Wang Bai was speechless. These surrendered people had no way to survive. Could he not pick up guns and attack?

After firing a shot, Sato gave the other party time to react and even leisurely explained to Tanaka.

This idiotic move easily conveyed a message to Wang Bai: Sato, that old man, was looking for trouble again.

Without a second thought, Wang Bai retreated from the stairwell.

Let Sato have some fun. He's already stolen the limelight; he's probably been holding back for too long.

From another perspective, they lack the ability to control prisoners. If they send these guys back, they'll likely be used by the government as manpower in the next battle.

In the end, they'll still be enemies, so it's better to eliminate them now.

The gunfire stopped in less than half a minute.

It seems this small team is quite well-trained, managing to hold out for half a minute under these circumstances.

If Sato and Tanaka weren't demi-humans, it's possible that this small team wouldn't have been the ones to die this time.

Sato, carrying Nagai Kei's restraint bag, jumped off the rooftop.

This is a unique characteristic of demi-humans—their rapid descent down stairs.

It's way more sophisticated than a certain vampire stopping on the stairs, though the scene is rather gory.

……

"Kei Nagai, open your eyes!"

Driven by Wang Bai's obsession, Kei Nagai was bound to a chair while wearing a straitjacket.

This scene feels quite familiar; both Wang Bai and Tanaka have experienced similar scenarios.

This is why Wang Bai, who could have easily woken up Nagai Kei, chose to tie him to a chair instead.

This has become a special ritual from the research institute to Sato's squad.

After everything was ready, use a pistol to force Nagai Kei to power on.

Then comes the scene where Kei Nagai hears Wang Bai utter his famous line.

"The surgery was a success, you're a girl now!"

Kei Nagai was startled and instinctively tried to reach down, but his body was bound and he couldn't move.

But I could immediately feel the sensation between my legs, so I felt relieved.

I looked up and around at the doctor who had made the joke.

Kei Nagai then realized that he was not in the operating room of the research institute at all, but in another place.

"Where am I?"

Before Wang Bai could speak again, Sato preemptively said, "Young man, we have successfully rescued you from the research institute."

"Don't worry, we are the same kind of people as you."

Upon hearing Sato's words, Kei Nagai immediately realized: "You're both demi-humans!?"

Without needing Sato's reply, Kei Nagai immediately saw the evidence—the once-popular Ajin King, Haku.

"I see, thank you for saving me."

Kei Nagai apologized in a calm tone, his attitude was very sincere, but there was an eerie feeling to the calmness.

Tanaka, standing to the side, felt even more awkward. He had been crying his eyes out when he first heard those words, after all the times he had died.

The boy in front of me, named Kei Nagai, seemed as natural and unassuming as someone who had just gone out to buy soy sauce and was returning home.

In fact, this reaction surprised even veterans like Sato. Faced with such torment at the research institute, this attitude was indeed somewhat unusual.

Wang Bai wasn't surprised; knowing the original work, he knew that Nagai Kei's state was one of excessive rationality.

However, Kei Nagai gradually added a lot of emotional content after the main storyline, but this characteristic makes the other party have the potential to become a strong person.

Otherwise, why would so many people, so many subhumans, only Nagai Kei faced Sato and defeated him?

Seeing the reactions of the three people in front of him, Kei Nagai continued to plead, "Could you please let me go for now? I also want to let my family know I'm safe."

Sato was about to refuse, but Nagai Kei's words stopped him from speaking.

"Don't worry, I won't use electronic devices. Instead, I'll use letters or something similar to avoid letting the government find us."

Wang Bai stepped forward and used a knife to cut open the straitjacket on Nagai Kei's body.

Sato is now playing the role of the leader of an organization that liberates demi-humans, so he naturally cannot use brutal methods.

Before Wang Bai and Sato separated, he was happy to help the other party maintain this persona.

"Thanks."

Kei Nagai breathed a sigh of relief and subconsciously moved his body, finding that he felt no discomfort.

It seems he died once during the process of being rescued?

Indeed, the fact that the other party, consisting of only three people, was able to rescue him from such a research institute is already a testament to their strength.

Even having demi-human characteristics is a remarkable thing.

Thinking of this, Kei Nagai remembered his friend who rode a motorcycle.

"I wonder how Haidou is doing? Has the government made things difficult for him?"

"Kaito?"

Upon hearing Nagai Kei's words, Sato asked, "Is that a demi-human like you?"

Kei Nagai shook his head: "No, no, the other person is just an ordinary human being, my best friend."

Hearing this, Sato lost interest in asking any further questions; being a non-Ajin held no appeal for him.

"Young friend Nagai Kei, would you be interested in joining our team and contributing to the peaceful lives of the demi-humans?"
