Chainsaw Man: Mangekyo Sharingan

Chapter 111: Chapter 111: A Deal with the Sword Devil

After watching the situation for a few days, Kotone Asaba felt that there really did not seem to be any problem with this experimental base.

Once Denji gradually became familiar with the environment, the scientists also began preparing to let him come into contact with the devil hearts.

At present, the experimental base actually still had three devil hearts. They were the hearts of the Sword Devil, the Whip Devil, and the Katana Devil.

Of course, the people of this world no longer remembered the names of those three devils, because they had already been eaten by Pochita in Hell.

Their hearts, like Little Gun and Pochita, took the form of various small animals, with the weapons on their heads serving as their most obvious features.

Denji was not the only one involved. The scientists organized all the children in the experimental base to come into contact with those devil hearts.

It was an empty laboratory. The three devil hearts were each locked inside three relatively large glass containers, and the children would interact with the devil hearts through the glass to prevent any sudden attacks.

Kotone Asaba and Makima were also there, watching alongside the scientists.

"For some reason, these devil hearts all seem to have lost their memories. We cannot even determine their names."

At that moment, one of the scientists spoke.

Clearly, those words were directed at Kotone Asaba and Makima.

"Maybe some devil made them that way..."

Kotone Asaba said it casually.

A faint glimmer immediately flashed through Makima’s eyes. His words also reminded her that these weapon-type devils had all once been eaten by the Chainsaw Man, yet for some reason, they had not vanished completely, unlike other devils that had ceased to exist.

Could it be that these weapon-type devils had something special about them?

In truth, Kotone Asaba was a little puzzled by this too. It was not quite accurate to say that all weapon-type devils would not disappear completely. After all, after Pochita ate the Nuclear Weapons Devil, it ceased to exist, didn’t it?

"Maybe."

The scientist had never heard of a devil like that, but there were plenty of devils humanity had never encountered, so he thought it was possible.

They started with the Sword Devil. The scientists had the children come into contact with the Sword Devil’s heart one by one, lining them up according to their numbers and recording each child’s reaction with the Sword Devil’s heart.

The children had already been trained well. Almost none of them showed fear. If they had been ordinary children, they would not have dared to approach even with the glass between them.

More than half the children had already finished interacting with the Sword Devil.

None of them had any real "chemistry" with the Sword Devil. The Sword Devil either ignored them or acted fierce.

After losing their memories, the devil hearts instinctively had no particular fondness for humans. Whether they liked someone or not was purely based on mood, and they also had no idea what would happen to them next, so testing the devils’ reactions like this was very accurate.

For example, after confirming which child was the best match for the Sword Devil, they would begin the next stage of long-term nurturing, slowly cultivating a bond between that child and the Sword Devil. Once the child grew to a suitable age, they could begin the formal experiment.

Eventually, there was finally a child who made the Sword Devil show a slightly better attitude, but it was only that much. It still did not reach the standard the scientists had determined.

At last, only Elena and Denji had yet to interact with the Sword Devil. Their numbers were 43 and 44.

"Elena, you can do it!"

At that moment, Denji suddenly shouted.

The surrounding children immediately looked at Denji and Elena with all kinds of expressions, surprised, strange, amused...

In such a serious and solemn process, only Denji would shout encouragement at someone like that.

Also, Denji was speaking Russian. He had been learning Russian every day for the past few days. Although he still could not communicate normally, after learning the phonetics, he had memorized some common words, including "Elena" and "you can do it."

Elena’s originally aloof and serious little face immediately failed to hold itself together. Her cheeks flushed red in an instant as she said in embarrassment and anger, "You...!"

Based on Elena’s expression and tone, Denji could barely understand what she wanted to express, and he immediately became somewhat confused.

He was obviously cheering Elena on, so why was Elena angry?

Seeing Denji’s innocent little eyes, Elena could only sigh. This guy was always so oblivious.

Kotone Asaba found the scene rather amusing too. It seemed Denji was getting along pretty well with that girl.

At that moment, Elena stepped forward to interact with the Sword Devil, and as expected, she did not get any good reaction.

However, the Whip Devil’s heart in the glass container on the other side reacted. It jumped around restlessly, seeming to like Elena very much.

After noticing this, the scientists immediately made an exception and had Elena switch to interacting with the Whip Devil’s heart.

Elena tried placing her hand against the glass, and the Whip Devil’s heart inside was as delighted and excited as a pet dog seeing its owner.

The scientists had never seen such a situation before, but there had not been many Hybrid experiments in the first place. In any case, this showed that Elena was extremely compatible with the Whip Devil.

After this, there was no need to let the other children continue interacting with the Whip Devil. Elena only had to wait for the next stage, where she would slowly become familiar with the Whip Devil.

The Sword Devil’s round was not over yet. The last child was Denji.

Denji walked toward the Sword Devil with great enthusiasm, but the Sword Devil did not really pay him any attention either. Maybe the Sword Devil cared about appearances. If someone’s looks did not impress it at first sight, it simply ignored them.

The child who had made the Sword Devil show a slightly better attitude earlier had been a pretty cute little boy.

Denji could not exactly be called ugly, but saying he was very handsome would be a lie. Still, whether he was handsome or not was not the important part. The important part was that Denji’s personality was one of a kind, with his own unique vibe and charm.

"Hey, hey, hey, why are you ignoring me?"

Denji patted the glass.

Under normal circumstances, the Sword Devil should not have understood what Denji was saying, but by coincidence, the Sword Devil knew Russian, Japanese, and English.

Even so, the Sword Devil still ignored him and even turned its head away.

But Denji still did not give up. "Say something already. Aren’t devils supposed to talk? Or do you not understand Japanese?"

The Sword Devil was already getting a little impatient, veins bulging on its face.

"Aaah! You’re so annoying! Can you go away?!"

The other human brats from before would leave on their own as long as it showed them a bad attitude or ignored them.

Only this brat was different. He was annoyingly clingy, like a burr stuck to its fur.

The Sword Devil’s voice sounded female. No wonder it cared about looks, and no wonder it ignored girls even more.

"Oh?! So you can speak Japanese. That makes this easy!"

Denji became even more excited instead. "Look, I’m the last one anyway, so why don’t we just settle for each other?"

"Settle my ass. Hurry up and get lost. Stop bothering me."

The Sword Devil spoke in an irritable tone.

The surrounding children were all dumbfounded, and the scientists were surprised too.

Throughout the entire round, this boy was the only one who could make the Sword Devil speak. However, it was speaking Japanese, so almost none of them understood it.

Although they could tell from the Sword Devil’s expression and tone that its attitude toward Denji was not friendly, it was still remarkable that he could make the Sword Devil say so much.

"Come on, settling for each other is great. Don’t you have anything you like? If there’s something you want, I’ll do my best to get it for you later."

Denji said.

"Like? I like drinking human blood. Do you dare give me that?"

The Sword Devil deliberately sneered, trying to scare Denji.

"Sure. If you agree, I can give you my blood."

Denji said it almost without hesitation.

He knew very clearly in his heart that he had to become a Hybrid, or sooner or later, he would die from his heart disease. Compared to dying, giving a devil blood really was nothing.

"..."

This time, it was the Sword Devil that fell silent. "I really don’t understand you, human brat. Fine, I guess that’s still better than being kept locked up by those people all the time."

Although this human brat’s appearance did not meet its "taste," the way he was different from the other human brats had caught its interest.

"You said it yourself. From now on, whenever I want, you have to give me blood."

The Sword Devil deliberately tried to scare him again.

"That won’t work. At the very least, I can’t die. If I die, then it’ll all be meaningless."

Denji began negotiating terms.

"Of course I won’t let you die, but I’ll drain you dry. If you have the guts, I’ll reluctantly agree to settle for you."

The Sword Devil said.

"Then it’s settled."

Denji nodded almost without thinking.

"You brat..."

The Sword Devil was a little speechless. It could not tell whether this human brat was oblivious or something else.

In reality, most of what it had just said had been meant to scare him. It only wanted to test and frighten this brat a little, but it had no effect on him at all.

Watching this scene, Kotone Asaba was a little surprised too. Denji had actually talked the Sword Devil into agreeing through sheer persistence.

Only a guy like Denji could chat with a devil for half a day. If it were any other child, how could they dare say so much? Especially after getting snapped at by the Sword Devil.

This made things easier for him. He did not even need to use an illusion to control it.

His original plan had been to use an illusion to control the Katana Devil’s heart and forcibly make it fuse with Denji to turn him into a Hybrid. Only after arriving here did he discover that the experimental base also had the Sword Devil’s heart, and Denji had even convinced the Sword Devil on his own.

If Denji really could fuse successfully with the Sword Devil’s heart through his own efforts, that would undoubtedly be the best result. After all, Denji would essentially be coexisting with a devil, so it would obviously be better if the human and devil had a close relationship.

Voluntary and forced were fundamentally different, especially if Kotone Asaba forcibly controlled it with an illusion.

At that moment, a scientist who understood Japanese also explained to the other scientists what Denji and the Sword Devil had been discussing.

This surprised them quite a bit, because this situation was unprecedented. A child had been able to chat with a devil for half a day and forcefully talk the devil into agreeing.

No wonder the military higher-ups had specifically recommended this child. He really was different.

Today, both the Sword Devil and the Whip Devil had found matches. For the experimental base, this was a major gain and breakthrough.

Next was the Katana Devil. Aside from Denji and Elena, the other children all interacted with the Katana Devil’s heart like before.

The result was just as expected. The Katana Devil was not interested in any of the children.

Kotone Asaba knew very well that as long as he did not forcibly interfere, the Katana Devil’s heart would not find a match for at least the next three or four years. Otherwise, it would not have ended up being Daiki Hamano’s turn in the original story.

However, the scientists no longer cared about the Katana Devil’s result. Their minds were now on the Sword Devil and the Whip Devil.

Also, by coincidence, the two people compatible with the Sword Devil and the Whip Devil were roommates.

Afterward, the children all dispersed, and the scientists specifically spoke with Denji and Elena.

"From now on, each day, you will have a fixed period of time to interact with your corresponding devil hearts. You will try to form contracts with them, such as a contract that they will not harm you, and slowly move toward closer contact with them."

Starting tomorrow, Denji and Elena would gradually begin close contact with the Sword Devil and the Whip Devil.

Now, Kotone Asaba felt there was nothing to worry about. He prepared to leave this place with Makima. In the future, he would have the military higher-ups send people to observe Denji’s situation.

According to the experimental base’s procedure, Denji would need to stay here for quite a while.

That was because the minimum age for undergoing a Hybrid experiment was at least sixteen. That was the rule here.

The reason was simple. If someone was too young, their body would not be fully developed yet. Once they became a Hybrid, their figure and appearance would no longer change at all, so being too young was not suitable.

With medication to ease his condition, Denji would definitely be able to live normally until he was sixteen. Although it would take a while, there was no need to rush.

As for his education, he could study here. The conditions here were actually quite good, and Kotone Asaba felt that Denji might even manage to get himself a little girlfriend here. Things seemed promising with that Elena girl.

......

The two of them returned to the dormitory to rest.

Although it was rest time, Denji wanted to learn Russian faster, so he used the translator the scientists had given him to communicate with Elena. "I want to learn Russian sooner. Teach me, will you?"

The translator received the Japanese Denji spoke, then automatically converted it into Russian and played the sound aloud.

"No. I want to rest."

Elena turned her face away, giving Denji the same cold attitude as always.

Elena’s words were also converted into Japanese through the translator.

However, Denji did not care about such a minor thing at all. He pulled a few lollipops out from inside his sleeve.

"How did you...? You actually dared to secretly hide snacks and bring them back to the dormitory?"

Elena was instantly surprised.

Denji hurriedly covered Elena’s mouth with his hand. "Shh... Keep it down. Don’t get me in trouble."

Having Denji suddenly cover her mouth with his hand, especially from such a close distance, made Elena’s little face turn slightly red. Her gaze also shifted away, avoiding eye contact with Denji.

"I just noticed you usually seem to like lollipops, so I figured I’d secretly bring some back. I knew they’d come in handy eventually."

Denji honestly stated what he had been thinking. "So, in exchange for the lollipops, teach me more Russian."
